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?
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
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)
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.
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
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.
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..
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.
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.
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
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?
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.
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.
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)?
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.
Hey guys, first post here I came across this thread in google So kinda diggin up an old thread here just had a few questions since this seems to be the most knowledgeable place on this laptop
Short story, I'm in the market for a new laptop (replacing my nc8000) and my employer just got a new macbook to replace his dv8000, deal is if I move all the crap from the old laptop to the new one, I get the old one for free
First off, the CPU fan is about to die. Can someone confirm that 407862-001 is the correct P/N for this laptop? Its the core duo not amd which seems to make things really confusing. I looked at both HP service manuals and its obviously not the AMD cpu, but the intel manual says that its just a Pentium M (I didn't see anything about core duo)
I think technically speaking this is a dv8300... just to make things more confusing.
Second, I plan on upgrading the CPU from a T2250 to a T7400. My question is, can 64bit be used? The CPU can do it, IIRC the chipset can, OS can, but the BIOS I don't know about.
Also FWIW I ran CPU-Z on my dv8000 and the ram specs show DDR2 PC2-5300 in both slots running dual channel.
I swear every thread I find about this laptops people are listing off different specs....
Thanks!!!

The laptop will be able to run 64-bit. Your biggest problem would be drivers.

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!
