HP dv8000t Taken Apart

[Sledgehammer70]

Well Myself and MackOCZ decided to see if a CPU upgrade is possible when the new Intel Meron chips roll out. Well to get to the CPU in the dv8000t is not a simple task... But it is possible and now I know how to clean this bad boy after a few years of use. I also want to note we replaced the CPU Thermal grease with Artic Silver 5 :)

I suggest not trying this at home unless you know what you’re doing....

Cool, you got that puppy stripped down. :thumbsup:

[citrixmeta]

u guys are nuking futs! i wish i was there for that!!!11

[Sledgehammer70]

It was one of the hardest and time consuming disassembling I have ever done.

[GHoosdum]

Wow, that is an impressive photo.

Are you planning to write an article about the teardown?

[Sledgehammer70]

A few more images of the massive fun....

[Sledgehammer70]

I was thinking of it... but I might do an article on how to upgrade your Core Duo CPU.

That would be pretty freakin' sweet. I love articles that set S-M apart from the other tech sites, and that would be one of them.

Don't tell HP that he used Sauza Gold Tequila to clean the old heatsink gunk off ;)

[airbornflght]

lol, why are you wasting the good stuff on a HEATSINK!! crazy man!! rubbing alcohol is much cheaper.

[Mt_Goat]

Gigantor I mean Sledge

Let me know when you figure out where the extra screws came from. OK?

[RyderOCZ]

Good thing you had some great coaching :D ;) ;D

[Sledgehammer70]

Don't tell HP that he used Sauza Gold Tequila to clean the old heatsink gunk off ;)

It was the last resort... We had nothing else to use... I think the goal was each dip with the Q-Tip you had to take a swig of Tequila and than wipe the CPU...

[Sledgehammer70]

Let me know when you figure out where the extra screws came from. OK?

What screws...????

[Mt_Goat]

What screws...????
Oh, I remember now. You put them in that glass of water so they wouldn't get lost. Then the glass almost got knocked over and it was removed from the table. ;)

[cridgit001]

Were you able to find the GPU? If you did do you have any pics?

[Sledgehammer70]

Yes the GPU is under the Grey Block to the right "look behind the cable with the red sleeve... It is non removeable....

[Mt_Goat]

He was able to locate the GPU but it would have been much more involved to get the HSF off od it. His initial quest was to see how accessable the CPU was so that he could update it to a Merom when they arrive. See here. (http://http://www.short-media.com/forum/showthread.php?t=47575)

[maxclark]

wow...that thing got stripped...lol..so many parts to a computer...wow...:thumbsup:...

[maxclark]

ive been inspired also...now where is my comp?? ;)

[SuperEula]

Hey, is that an HP security card you found in the notebook (between hard drives and mouse in the pic)?!? Bet that could come in handy when you want to wander around the HP production plant... Oh wait, that would require a trip to Singapore or such. Better start saving up those frequent flyer miles.

this is my processor, but it says it is 479mPGA, but the removable (i think) core 2 duos are 478 mPGA,

the number of pins are different, how did u come across this>

[Sledgehammer70]

Core™2 Duo Mobile processors (T7000 & T5000 Families)

The Core™ 2 Duo Mobile processor family consists of five processors currently: the T7600, T7400, T7200, T5600, and T5500. They run at clock speeds from 2.33 GHz all the way down to 1.66 GHz. The T5600 and T5500 are equipped with a 2MB L2 cache and the T7x00 models have a 4MB L2 cache. All five of these new mobile processors use Intel's 65 nm manufacturing technology packing 291M transistors into a die size of approximately 143mm2. Like the previous Core™ Duo, the Core™ 2 Duo processors utilize a 667 MHz front-side bus, and support DDR2-667 SODIMM memory. These Core™ 2 Duo processors voltage draw ranges from 1.0375V to 1.3V, are rated at 34W thermal design power (TDP), have a thermal specification of 100°C, and use the standard mPGA 479-pin socket (Socket M) found in all current "Napa" (945GM/PM) BTO notebooks.

Don't know where your reading about a 478 mPGA.. as the 478 CPU is a P4

[alnazli]

Don't know where your reading about a 478 mPGA.. as the 478 CPU is a P4

it read it in this intel document (ftp://download.intel.com/design/mobile/datashts/31407801.pdf) about core 2 duo section 4.1

maybe i am reading something else :scratch:

[Sledgehammer70]

The above blurp is also form Intels site :)

As far as I can tell the Pentium 4 Northwood was based on the 478 mPGA

The New Core 2 Duo Notebook chips are on the 479 as seen here:

http://www.xoticpc.com/laptop/core2image.jpg

[alnazli]

u got it from here (http://67.91.114.164/inetpub/ftproot/intel_c2d_mobile.htm)? but that's not intel's website

if u look at intel's specs finder (http://processorfinder.intel.com/List.aspx?ProcFam=2643&sSpec=&OrdCode=)

u will see that each is offered in two different packages the 478 & 479, and according to that document i mentioned about, says the 479 is BGA (soldered) and 478 is PGA (removable)

and u made the processor upgrade and it is 479, this is very confusing :scratch: :scratch: :scratch:

[Sledgehammer70]

My laptop reads the socket as a 479.... and not a 478 and it is very removable. I am not sure what else you want me to say? I am only reporting what I have done and what my Laptop is telling me. I didn't do anything special to make it work differently, just dL'ed & installed HP's bios update. either which way it would probably been cheaper to take a loss on selling my laptop and buying a new laptop from HP that comes with the CPU....

i am not asking u to say anything, i am just sharing what i found from here and there

so maybe someone got an answer/explanation for all of that :)

[RWB]

Hey sledge, I am LOST.... what are you trying to accomplish? I checked into possibly upgrading my Pentium M to a Core 2... I have the proper socket but was told the Intel chipset will not support the new processor :(

If it is possible THEN I WOULD LOVE TO SPEND MONEY!

[Sledgehammer70]

In all my research and my testing, I contacted HP they said it was possible but not recommended "due to they don't like users breaking apart their systems" I checked the chipset and the bios, which they all support the C2D's so I purchased a C2D, re broke down my laptop as I did in the above image, and dropped the chip in. Now if the chip was a 478 or a 479 to fact stands that when I put the Laptop back together again it worked. Now this is on a DV8000t not a dv5000t, the dv5000t from what I have learned in the past has a way different build...

But over all the 64bit boost I think is the only think I can say was worth the upgrade, as if you even ask other SM guys that saw & helped me break this thing apart would agree that there was times when this sucker just about broke. Even taking it apart a few times I still had to force and pull things to the point I was afraid it was going to break... so be advised if you try this, be very careful.

[RWB]

Well if I could upgrade my CPU... I only have to remove a hatch and viola... I can replace the CPU :P Same goes for pretty much everything but the motherboard itself.

But it appears that I cannot get a nice upgraded CPU like that... maybe in a couple years when the warrantee is up I'll try to do some modding and get something more powerful put into my lappy.

[DenasenOCZ]

Hi Sledgehammer70, just bought myself this baby, the first one had a motherboard problem so they replaced it. The problem is in this part of the world (Africa|Kenya-Nairobi) HP support is quite far both at warranty & parts support (Middle East). I had a XP media & WSXGA (1680X10X0)on the machine that developed the MB prblem could not recognize the DVD-DRIVE completely!

As it were in your investigations is it possible to replace the NVIDI Go7400 with something higher so as to be able to do this resolution?

I look forwrd to the disassembley guide for this baby.

What were the performance gains from the processor upgrade? could you post comparative benchmarks?

Grateful

Another OCZ rep on S-M. Awesome! Welcome, Denasen.

[steelclash]

Hello,

Looks like an old thread here, but it is relevant to my current problem. The fan over the CPU is making noises, and I suspect the baring is to blame. I know if I can get to it, I can grease it. I have taken it mostly apart, but couldn't get to the portion where I could access the fan.

Do you still have any pictures or instruction in reaching the CPU fan?

Thanks in advance.

[Sledgehammer70]

the problem is... to get to the fan you have to remove the mobo from the bottom plastic casing... only than can you get to the fan. It seems like a tight fit where the USB ports are but it semi forcibly will come out...

[steelclash]

the problem is... to get to the fan you have to remove the mobo from the bottom plastic casing... only than can you get to the fan. It seems like a tight fit where the USB ports are but it semi forcibly will come out...

Well, I guess it's just unclear how to separate the mobo. The grayish portion seems to have a snap system that I started to unsnap. One side unsnapped pretty easily, but the other end doesn't seem to want to come out at all and I'm afraid to really force it.

Maybe you can see if I'm doing something wrong: I take out the battery and memory and disconnect the wireless card. Then I take the keyboard off and remove the screen from the base. After this is where I'm alittle hazy. The gray portion on the left side (AC power side) seems to snap off pretty easily, but the side that has the DVD-RW doesn't seem to want to budge.

Is there something I should be doing differently here?

[Sledgehammer70]

take everything off, slide the dvd tray out and on the side with the media card reader is where your going to have to apply the most force... At one point i almost though I snapped the mobo, but with patience and doing it slowly i got the exp port and svideo and USB ports to come out...

Just make sure all the sqrews holding the board down are removed... remove the speakers etc.. everything. the entire system has to be broken down to remove it.

[steelclash]

Well, after about 2 hours of work, I was able to get to the cpu fan. I put some 3-in-1 oil on the baring as best I could, but alas it is still rattling away. Seems like it is still able to blow air out, so I guess I'll just have to live with the noise.

Thanks for all the pointers.

PS: I took some pics of it apart as well. Was pretty fun.

EDIT: Seems as though I'm not quite privileged yet to post my picture. Oh well.

[Sledgehammer70]

I think there is a 5 post rule... I could be wrong.

[steelclash]

=/

Now that I got my comp up and running (posting from) I realized I have a few screws left over. Eek. Hope it doesn't fall apart >.,

[Keebler]

You can post pics now, all fixed.

[steelclash]

http://i118.photobucket.com/albums/o101/gamephase2002/LaptopDisassembly003.jpg

So, after all this work, it looks like no amount of grease/oil was able to fix the problem. Looks like I'll need to get a new fan.

Anyone have any idea what I could replace the fan with?

EDIT: Well, I found the replacement part for it. Looks like you have to buy a new heatsink/fan assembly at the price of $70. Quite the headache.

For anyone else that has this problem, the part number for reference is 407862-001 .

[Sledgehammer70]

I so remember all those parts....

[CB]

That picture makes my teeth hurt...

I got my HP dv8321tx upgraded to T7200 too. :bigggrin:

In order to break it down, you need the 'Service and maintenance manual' from HP.

And thanks Sledgehammer70, the first useful stuff I found was the article post by him.

(I am not allowed to post the links :mad: )

Cheers!

[Sledgehammer70]

Glad to hear I could help... in some sort of way :) how's the new CPU running...

[Bez]

Hello every one,

hey Sledgehammer70, bravo! i am sure it took allot of guts.
great stuff.

I was searching today in google so long, to find exactly this.
I own a dv8391ea (sorry, can't post links yet even as plain text?)
it looks like yours, but I was wondering what is your
model specific name? do you think it's the same?

my specs are,
cpu: is T2500, video: nVidia 7600 256 mb, monitor: 17 inch 1440*900,
storage: 2 hdd 100 gb.

I was chatting earlier today with an HP online tech, guy,
I asked him about what chipset I have? he said nVidia 7600.
I told him that I mean the mainboard, cpu chipset?
maybe I don't know some terms when it comes to lappi's,
like what is a mobo? anyways,
he couldn't really help me there, but he did say that the cpu is soldered,
and I won't be able to upgrade, I didn't believe him.

cpuz say the following in my laptop:
CPU:
T2500
Package: Socket 479 mPGA
Mainboard:
Chipset: i945PM
Southbridge 82801GHM(ICH7-m-DA)
Memory:
DDR2
Frequency: 332.5 MHz (is that ok?)

A bios update was issued to my specific model at may 25 2007,
but I did not install it yet.

It would be so cool if it would be possible to also overclock
the new chips to around 2.7Ghz, maybe 3Ghz :rarr:?
they produce less heat, those chips, no?
and you also replaced to a better cooling sink,
did I understand that correct?
it's a shame that upgrading graphics is not possible,
Or do you think someone crazy enough might be able to?

I won't try any thing soon, but maybe one day I will.
you all sure inspire me, fantastic job!

Hope to hear more news about how are performance wise was it really?
do you really see a big performance boost in games and such?
if you would be able to overclock your cpu maybe it will be even better.
it's a shame because this laptop is really good but the cpu is not a gamer cpu,
if it's possible to overclock this to 3Ghz, do you think it would make
allot of a difference in performance?

in short: is it worth the hassle?

Again, fantastic effort,

thank you in advance,
Bez.

-EDIT-

fucintosh, I have googled the user manual number you posted
and also found a different one named --> c00637497.pdf
I found it in a post in a site called "r3000forums"
I am going to check if they look the same...

they are different a bit, I didn't check everything but
in the PDF you mentioned it's written about AMD processor,
while the PDF I have found show a strange thing in processor section:

Processors (include thermal paste)
407763-001 Intel Pentium M 21.7-GHZ
407662-001 Intel Pentium M 2.0-GHz
407661-001 Intel Pentium M 1.83-GHz
407660-001 Intel Pentium M 66-GHz Dual Code <-- (what is that?)


I don't find a manual like this in HP site under my laptop model, dv8391ea,
But I do know that the PDF I have found in the other site
is for the dv8300 serie, so,
I am assuming I can upgrade with out any fears, right?

sorry for the very long replay.

thank you for all your help.
it was allot of time until I found your post here, pure luck!

[Sledgehammer70]

I had the dv8000t CTO it sported the T2600 Core Duo processor.

I hate to break the news but you can OC the CPU :( but you can download and install many different utilities to OC the GPU. While i never OC'ed mine I know it is possible with any Nvidia GPU.

If you could honestly upgrade the GPU and still have a working Laptop I would be amazed. The chip is by no means removable or upgradeable...

DDR2
Frequency: 332.5 MHz (is that ok?)

Right on par with what it can do. The Core Duo can only support upto 667MHz Memory which is 333Mhz Single channel.... so your good to go.

Bios updates are always good, but HP will never unlock the mobo for OC'ing. if soemone could find away to enable it I would pay some cash for it :)

[Bez]

hey Sledgehammer,
thank you for your quick replay,


I hate to break the news but you can OC the CPU :( but you can...


now, I am assuming you meant can't, and that is ashame,
though I have seen here and there in the net some people that
claim to OC thier laptop to the around 3GHz clockspeed,
should I believe it? I don't know.

regarding the GPU,
since you and maybe a few others are the only one that
actually have seen this baby from the inside and won't lie about it,
did you manage to see if this laptop use the MXM module?

I do know that some of the NX9000 models are on the list in the
MXM-upgrade website.
I would like to believe that the dv8000 has MXM,
if so, an upgrade would be possible, no?


hope to see a guide on upgrading the CPU,
that would be great,
Ho, and I am really interested to know,
do you see allot of perfformance boost? was it worth it all?

again thank you for sharing your info,
Bez.

-EDIT-
Sledgehammer, did you ever read this article? "Mobile CPU Wars: Core 2 Duo vs. Core Duo" in the AnanDTech website?
can't post links yet, sorry. interesting article.

I actually did some research on upgrading the CPU, and I concluded that it wasn't worth it. Right now, we have a desktop version of the core duo. You'd have to upgrade to the core 2 duo mobile which is a weak version of the chip. Sure it's an upgrade, but it's so minute that it's not worth the cash or effort of installing.

Also, overclocking the GPU is very easy. Google "Coolbit". If you have 9xxx+ drivers, overclocking software is included, which also contains a temperature reader for the GPU. I have successfully overclocked the GPU by about 100 mhz with no major change in temperature and no graphical anomalies.

Good luck if you decide to upgrade the CPU though. :)

EDIT:

To clarify the GPU overclock. You have to make some additions to the registry, then the nVidia control panel will be available. (which contains the stated tools)

Edit 2:

bah, coolmax -> coolbit

Found a link: http://www.nvnews.net/vbulletin/showthread.php?t=29541
This is a good guide to getting it running and how to use it.

Wow, thank you steelclash,

I was actually just thinking of doing that to my GPU,
I have forceware 84.54, they are the original drivers I got from HP,
never changed them, never needed to.
I have the 7600 256 mb, do you think it would work?
should I update my forceware even if nothing is broken?

Just yesterday I bought "R6 Vegas" and that
is the most intensive game I had to date on my laptop.
would be nice to overclock my gpu just for this game!

I'm using driver 91.33. They are the most optimal and most recent available for this particular GPU.

It's kind of hard to come by. That being said, the best place to get them is http://www.laptopvideo2go.com/ . Find forceware 91.33, download the driver, then you will need to download the .inf file. They are both located there.

You'll unpack the driver into a folder, then copy the .inf into that folder. Since nVidia isn't so keen on supporting laptop go cards, all forceware drivers support pretty much every nVidia card product, but for legal reasons, they don't include most go cards in the inf file.

I've been using these drivers for the past 2 months, and they work very well. Much better then the stock 84.54 drivers.

Hope that helps.

EDIT:

I have my GPU overclocked to the following:

433 MHz on the Memory Clock and
471 MHz 3D clock

You can go higher then these, but you will start to see some texture corruption.

[Sledgehammer70]

Try these drivers...

XtremeG MobileForce- Windows Vista 32bit & 64bit

- XtremeG MobileForce 32bit - 101.70 WHQL - 33.5MB (http://www.nvrev.com/drivers.html)

Also the GOU is built onto the motherboard and not based on a MXM Board... As far as I know Non of HP's laptops use a MXM board. :(

Also while you can get the memory boosted it is only the provided memory, You are not able to OC or boost the shared system memory. so if it is a 7600 with 256MB your only OC'ing the 256MB not the shared memory. ( Most of these chips will use 370+MB of system memory....)

[Bez]

Thanks Sledgehammer, steelclash,

I am using xp sp2, not vista, are they ok for xp also?
also, how can I check what is my stock clock/memory clock speed?
rivatuner?

I went to their site and it is mostly for desktops,
didn't find any real answers for notebooks.

and since you guys have the notebook as I have,
I was wondering maybe you know what software is best
for finding out with out frying the gpu?

never OC anything before not even my desktop,
should be fun though,

thanks.

-EDIT-
Sledgehammer, I found only 101.17 for xp 32 bit not 101.70 did you mean those?
Steelclash, I have found 91.33 but it does not state support for Go 7600,
How safe is it to do these things assuming I don't OC to much,
can I really fry my GPU, or is it only myths?

I really appriciate all your help, thanks.

[steelclash]

No drivers out there specifically support 7600 go other then the 84.54. Reason is, nVidia left it up to the manufacturers of the laptop to provide driver updates. nForce drivers support all gforce cards, however they took out the 7600 go from the inf file.

You can download the inf file that people have modified to add all of the go cards out there and the installer will fix you up.

91.33 is about the best ones out there for 7600 go, after that most of the drivers are focused on issues unrelated to 7600 go cards (especially features that aren't included on the card). Sledge may know more about this then me, so correct me if I'm wrong here. I've tried a lot of different drivers including 100.xx+ drivers, and I have found 91.33 to be the most stable and best performing so far.

Keep in mind, I don't have Vista, so if you plan to upgrade, you might wanna go with Sledge's driver suggestion. On XP, I think these are gold.

It's very difficult to fry the gpu, you have to "test" the OC settings you use prior to applying them. There is also an option to only use the settings until you restart, that way if your gpu overheats and shuts down or freezes, then you can just restart back with normal settings. Either way, most of the time you will see memory corruption if you set it the frequencies too high.

EDIT:

Also when changing your drivers, it may be best to download some driver cleaner software to get rid of all the old driver components prior to installing the newer drivers.

[Sledgehammer70]

For Windows XP these driver seemed to work the best for me

XtremeG MobileForce- Windows XP 32bit & 64bit

- XtremeG MobileForce 32bit - 97.92 WHQL - 37.3MB (http://www.nvrev.com/drivers.html)

The drivers are rock solid for the 7600Go and should work for you overall...

Also you won't fry your GPU with a driver update, and in most cases (99%) you will not fry the GPU when overclocking. Nvidia has some nice shut down features when the core gets to hot. Worst case, your laptop will just shut off.

[Bez]

Hey Sledgehammer,

I know this is not the place for this but
I registered in the tweaksrus forum but it will take some time
until I could post, so,
I was hoping you could help me,

I installed ForceWare 97.92 M4 just like they explain in the site,
(didn't find WHQL)
with Driver cleaner and Ccleaner and so on...
but I fear I might got a virus from that,

after rebooting with the new drivers,
there is a process called wmiprvse.exe,
I googled it and as you probably know it's some Microsoft s**t.
But the strange thing is that the process is always jumping,
as in blinking in the task manager, and it is there 2 times every
time it's appearing, more over my mouse cursor
is now having the "thinking" icon (sand clock) every few seconds (flicker)
I have seen in google that this process could also be a virus,

Did I do something wrong? ;..(

every thing is working fine, games also,
with out overclocking, my core is 450 and
memory at 600!!! is that for real?

To how much did you OC your GPU?

Again, sorry for totally changing this thread into OC help forum.
I hope you could help me with this last question, (I hope)

thank you all very much.

-EDIT-
I OC to core: 585MHz memory: 876MHz,
I did not touch any bios stuff, should I?
I just clicked the detect optimal frequencies button and hop!
temp in idle mode is 56 cel. looks promising! : )
will check later in Rainbow6 vegas.

thank you again.

[Sledgehammer70]

detect optimal frequencies is the best way to go with coolbits :)

as far as the (wmiprvse.exe) I think you should be fine, It is just a MS service... I hear some say get ride of it and some say keep it. Might have been something Nvidia tacked on. It is not a virus :)

Thanks to Nvidia I am unable to get the coolbits hack to work in Vista. (well at least the version I have now). I think I will go on a hunt for a Version that will work in Vista & with Nvidia's new dumb control panel.

[Bez]

ok, I don't get this anymore,

Lost cost video stress test:
84.54 --> 48.37fps
97.92 --> 47.41fps
97.92 (OC with detect optimal frequencies) --> 7.73fps

After seeing the fps in lost cost are so bad when OC
I decided to try R6 vegas, it was the same as in the
84.54 more or less about 30fps average by eyeballing it,

And now the strange part comes in,
when I quited R6, I saw that the core/memory
went down to the stock 450/600
and now I can not change the OC at all,
any settings I put in manually it says: test failed try lower the speed,
but even lower than the stock speed is not possible.
when I try to press the detect optimal frequencies again,
it just put me back at stock 450/600.
what gives?
Does it mean that my BIOS or videoBIOS is locked?

[Sledgehammer70]

try a fresh restart.. sometimes it gets locked up.

[Bez]

thanks, it's better now.

Though I am sure I have a leak in the wmiprvse.exe process.
I will solve it with the help of the tweaksRus forum guys.

thank for all your help!
Bez.

Ok, I realize this all about the dv8000t, but I am curious about the dv8040us which is the 66-bit machine. I have been downloading HP's crap BIOS and I still can't attach a USB device to boot off. Is there a way to install another BIOS (believe that the HP firmware is just branded AWARD BIOS), and assuming that I can do that, would I be able to boot off of a USB device?:confused:

[Sledgehammer70]

Hard to tell. On my dv8000t I was able to boot off a USB drive when bios was set to look at external devices... I am pretty sure your dv8040us is the same build... But I am unable to check it, as I no longer own the dv8000t :(

[dvpuuw]

I've got the same problem steelclash had, awful noise from the fan (have owned for over a year, and it just happened) Gonna order a replacement and attempt repair. Wish me luck! (any pointers would be appreciated)

[Sledgehammer70]

its tons of fun getting to it :) if you have questions feel free to post them here.

[battery55]

its tons of fun getting to it :) if you have questions feel free to post them here.

I'm having a HUGE processor fan problem, much like the one posted earlier. It's making a terrible noise. It's intermittent and very loud. They decided to make this god forsaken thing impossible to work on, so I can't get to the processor without going through a whole lot of trouble. Do you have any suggestions other than taking it apart? Ive tried cpuclock and it's not doing anything. Anyway, if it comes down to it, if you can give me an idea of how to get this thing apart to the processor and what to do when I get there that'd help alot. Thanks in advance.

[Intruderscooter]

Sledge -

Your postings are very helpful. Thank you. One quick question...How do I remove the bottom cover of my dv8000 to get to the fan to clean it? I must have removed 13 screws and still could not get the cover off. You may email me at Intruder1400@triad.rr.com to provide directions. Thanks! Scott

[germanwolf35]

I got my HP dv8321tx upgraded to T7200 too. :bigggrin:

In order to break it down, you need the 'Service and maintenance manual' from HP.

==> google: c00701888.pdf

And thanks Sledgehammer70, the first useful stuff I found was the article post by him.

(I am not allowed to post the links :mad: )

Cheers!
I have the 1.8Ghz dual core,.. what is that new cpu? & WHERE can I find it? how much?

germanwolf31@yahoo.com

[germanwolf35]

Uhhh got mine apart & back together. Then No video and 4 beeps. What does that mean?

[Thrax]

It means you might have broken something. Try it again.

[germanwolf35]

Uhmm,.. guess it would help if I had plugged in the LCD screen. It's good now. but still lags a lot like before. Cleaning it & applying better paste for the cpu didn't help. I've tried all drivers new DirectX and a bunch more ideas. I'm at a loss.

[germanwolf35]

Exactly WHAT RAM is this supposed to use?? DDR or DDR2? & what model??

[Black Hawk]

DDR2 PC2-4200.

[germanwolf35]

Nope DDR PC2700... I just found out the specifics... thanks though

[Black Hawk]

Oh, that's a different laptop than the one in this thread. I thought you had a dv8000t.

<---- New Guy Sup all..

Hey I got this same notebook a while back .... Dv8000t... (runs great lol)
Anyways about a month ago I was getting really high core temps (80 -90c)

Decided to tear down the rig and do a little house keeping... removed a fair amount of dust, currently The cpu is at the bottom of the food chain.. (Yonah T2400 1.8 Core Duo) ... Applying Silver Thermal Gunk I cut the temps down a bit... but i must say the heat sink in this thing is kinda tiny wimpy XD...
Temps at load stay bellow 78C which i think is good enough...
Was wondering if anyone else noticed higher core temps on this model and if is common place.

Also on a side note... taking this thing apart with the Maintenance Book from hp at ur side is a must .... lucky me no missing screws / extra screws... actually I think at the factory they forgot to put 1 screw 0o... for the dvd/mobo gap bridge thingy ... not big deal i found one from an old broken lapy and threw it in there XD

Would anyone be able to answer me one question ...

Would buying Pc26400 Ram for this laptop Give me any Benefits.?
I am thinking of upgrading from pc5300 to pc6400 and well... i have read around that doing so sometimes causes a decrease in gaming performance on some laptops.... Would using Ram that runs above the motherboard bus speed cause such issues? Wouldnt the Ram just down clock to the bus speed?
Would doing so have a negative change on the cas latency of the ram?

This is the only thing keeping me from buying more ram ... as i dont know if i should go for the faster ram .... or the same speed ram...
Going to throw 4gbs...in since... i have no 64 bit support i will proly only get like 3.5 maybe w/e i know about all those possible probs... hoping since mobo and cpu are PAE supported it will use most of it.... we will see.
Sorry for the long read! Any input would be nice..

[dvpuuw]

finally did that planned fan replacement, a year later.

I messed up some on reassembling (put a screw in a wrong place, also had difficulty tucking the fan cable in its proper place), but I decided not to fix those to save time. Works great, no more noisy broken fan, only a small bulge in the keyboard from my screwup.

Hey there. I own a dv8308tx, and recently put in 2x2gb of RAM. In BIOS, it shows up as a full 4096mb, but when running my OS (linux), it only shows up as 3gb. I'm in the process of installing a new version of mandriva later this month, so I will keep you posted on whether or not it's any different. I hope that helps you out. I myself knew of the 2gb limitation, but decided to do it anyway. An extra gb does make me happier though! Happy computing. :rockon:

[donoterase]

In regards to your heat issue, I experienced the same thing about 2 months ago, where my system would idle at 65C, hitting 72C on light-medium load, and quickly hit 82C on heavy load, in which the system shuts off.

In my experience as a technical support specialist, I've learnt to rely on myself and no one from service centres, so I decided to take it apart and see what was happening under the hood.

To my amazement, dust and dust. It was all trapped in the groove in the heatsink, and was really clumpy. This obviously was blocking airflow trapping hot air in the laptop.

Plastic covering the heatsink. What was HP thinking.

DODGY thermal paste used. Ok now here's the thing. Prior to having this heat issue, the laptop had taken a trip to the service centre just under a year ago, but upon inspection of the thermal compound, it was very dry and starting to crack. Good thermal compound should last at least two years. This leaves me to believe the thermal compound used at the repair centre was low grade.

I removed all the thermal pads off the heatsink, and used Arctic Silver 5 thermal compound. Thermal pads are totally useless and unneccessary if you have good paste. Here are my system temps as monitored. Also shows before and after.

BEFORE
CPU IDLE: 65C
LIGHT TO MEDIUM LOAD: 72C
HIGH LOAD: 78C - 82C
HDD TEMP: 55C

AFTER
CPU IDLE: 48C
LIGHT TO MEDIUM LOAD: 55C - 60C
HIGH LOAD: 65C
HDD TEMP: 50C

It has not gone over 65C. Good thermal paste can do that. I'm very happy with these temperatures as they are NORMAL for my processor (T2250).

As for how I'm feeling about the process, the results speak for itself. My laptop is running smoother than it ever has been, a lot more responsive, and a lot cooler. I plan to upgrade the cpu sometime soon with a new core. They run a lot cooler.

[xenosaga21]

I took laptop apart put new thermal compound and got rid of the dust.
Good as new Temps Range 54- 65 Which is reasonable atleast.

As for the 3gb's of Ram from the other guy
Have you tried enabling PAE, i used everest to scan the mobo and it says it and the cpu are PAE enabled which should allow you to hit 4gb's

http://www.microsoft.com/whdc/system/platform/server/PAE/PAEdrv.mspx

Im going to buy ram soon... but i hear horror stories about other laptops where they used faster ram pc 5300 to pc 6400 and it caused a slow down in gaming graphics ( i suspect due to the shared ram link between the 256 dedicated and the system ram) that is suppose to enhance the graphics engine, by using some of the systems ram for the gpu.

I am thinking about getting some really fast pc 5300 ram... to keep clock speeds around normal but get some with a good Cas latency of like 4.

This in theory should reduce delay to a minimal and maxamize the potential gains.

Has anyone had any success with PAE? to address more than 3 to 4gb's of ram? within a 32 bit os like vista 32b or xp 32b?

[Thrax]

Enabling PAE will not enable the full 4GB of memory on any Windows OS. All current, updated 32 bit Windows operating systems can only recognize 2.5-3.3GB of memory.

[raywins]

Wow, glad I found this forum and your thread.
I'm replacing the keyboard on a DV8000 (AMD64) for a friend. "Someone" spilled something sticky on the keyboard and touchpad. I've got the keyboard replaced. Unfortunately, the touchpad buttons seem to stick also. It looks like a PITA to get to the underside of the buttons. Do you know if the buttons can be popped off to access the switches, like removing a qwerty keycap? I couldn't find any info in the HP Manual.

Tnx again for the great thread!

[Sledgehammer70]

I am so happy my endeavor a few years ago has help a handful of people... I should do these things more often :)

[Qnorsten]

Hello i am new at this forum found this searching through google in hunt of information about taking an dv 8000 apart.

I own a HP Pavilion dv8199ea that has been experiencing some overheating issues and random shutdowns, sent it in to hp they sent it back after a few weeks with a note that they couldn't find anything wrong with it.

I have reason to suspect that its dust inside the computer mainly around the heat sink that may be causing my problems.

I found the maintence manual on the net and are going to buy some articpaste. But now to my questions what tools do i need to be able to take it a part and clean it? And is it hard to do (I have pleanty of experience taking desktop computers apart but i have never dissambled a laptop before)?

Thanks in Advance
///Qnorsten

ps sorry for my english.

[GHoosdum]

Before you disassemble the laptop, I'd recommend using a toothpick in the vent to hold the CPU fan from moving, then blowing some compressed air through there to see how much dust you can free that way.
