   1 Sep 2004 ~ 3:34pm Unregistered You say that using a hairdryer on the processor will damage it. Actually, it won't have any effect, silicon doesn't melt until about 1200c. (yes 1200, not 120). When it's powered the heat generated changes how electricity flows though which can damage stuff, but you could probably put a processor in an oven when it's off and not do damage.
   
   Good article though

   1 Sep 2004 ~ 3:39pm MediaMan You are most likely correct about heating up a processor with a hairdryer but it's a good idea to use caution. Better safe than sorry.
   
   Thanks for taking the time to comment. We do appreciate it.

   27 Oct 2004 ~ 7:46pm Unregistered YAY! I've been trying to figure out WHY my Toshiba laptop was spontaneously shutting down. It is relatively new and I do all the maintenance things I'm supposed to (NAV, defrag, doctor, cleaning internet cache, etc.). I would get no warning, blue screen, etc. Just boom - complete shutdown. I followed your article and it was like a mirror! I pulled the heatsink out and there was 1/4 inch thick mat of dust, dirt, hair, etc. I did just as you instructed. My fan now runs intermittently on low, not on high. My computer is definitely running cooler. THANK YOU, THANK YOU, THANK YOU, THANK YOU. Diane M. Hess.

   Isopropyl alcohol
8. 
   14 Nov 2004 ~ 12:19pm Unregistered isopropyl alcohol leaves a film on electronic devices. That's why it is called rubbing alcohol. This could cause the heatsink to start burning that film and a host of other potential problems. It is better to use regular old ethanol, or, if your stubborn about sticking with isopropyl, they now have a cleaning grade isopropyl for electronics equipment.
9. 
   14 Nov 2004 ~ 10:45pm Thrax I've been cleaning my heatsinks with isopropyl for the better part of a decade. What you claim may be true, but after so long, I deem it nothing more than a remote possibility.
10. 
    6 Dec 2004 ~ 1:54pm Unregistered Thanks! I've been looking for something that I could do to keep my friend's-friend's Toshiba with a 2.8E "Preshott" from shutting down under load, especially since the pictures look very familiar to the said system.

    Really? You're lucky, cause I've been cleaning mine with bourbon and gin for the worst part of a decade. But yeah, during the better part, I used rubbing alcohol.

    11 Dec 2004 ~ 10:22am Unregistered The article is quite nice, pictures help a lot! However the advice is helpful only to owners of particular model machines. Unfortunately my laptop (HP) is not so easy to open and clean (40 screws have to be unscrewed...)
    But anyway this is a problem for laptop owners
13. 
    11 Dec 2004 ~ 12:35pm Straight_Man The discussion about Isopropyl versus Isopropynal:
    
    Ethanol is in essence a fast drying solvent. Alcohol does the cleaning well. BUT,70% Isoprpyl (rubbing alcohol) has lots of water content proportionally; is is about 1\3 water. Water that is distilled will take quite a while to dry, and I use 90% or better Isopropyl alcohol simply dues to the lower water content in the alcohol mix. It dries a lot faster with less H2O molecule content.You can add a small proportion of ethanol to 90% or better Isopropyl and you will not get a volatile reaction, but you then need good ventilation, as purified Ethanol is a poison. Isopropyl of 90% or better alcohol content works real well astually.
    
    The only thing that could be better is to polish the area of the Heat Sink that contacts the CPU die itself with 1000 to 1500 grit Wet\Dry Silicon Carbide sandpaper in order to in essence LAP the working\conductive face of the Heat Sink and get all the tiny remaining amounts of old HS compound off of the surface of the HS that contacts the CPU core\die. This also works to remove any tiny scratches on contact surface of HS.
    
    Same lapping process that works for desktop HSs works for laptop HSs and the BASIC procedure given here is good to follow with desktop Heat Sinks except for CPU removal which is close to toolless in ZIF desktop CPU socket. I say close to toolless rather than totally toolless since the swinging end of the lever on the ZIF socket release lever has to be released from its locking tang (I use the very tip of a jewelers straight screwdriver to unlatch the lever, myself).

    11 Feb 2005 ~ 1:20am Unregistered OMG Thank you so much! I'm a college student and have had this A25-S207 model for awhile now. At first I thought it wasnt getting enough ventilation and propped my laptop. Obviously that didnt work so I went searching for solutions. I'm so happy I found this tutorial on how to clean my laptop up. Its running like it was when I first bought it!

    4 Mar 2005 ~ 11:18am Unregistered HAHAHAHA sorted,i got a TOSHIBA A30 and it shut down under high load {trying to reistall windows...and it always shut down,infuriatingly around 98%complete..anyhow,i jacked the machine up on books to let air get in easier me thinks...and it completed ,great !} BUT now hang on a minute,why am i sitting it on books ???,so of to google and on to here...what?,heatsink?,dust? aha...10 mins later...back to opening line ...hahahahahahahaha. yup it worked,well,really well.Now somone deserves praise indeed .cheers!
16. 
    4 Mar 2005 ~ 7:26pm Unregistered Thank you Thank you Thank you. I tried about 20 things before doing finding this fix. You've changed my Toshiba A35-S159 experience...and save me $100 by not having to take it into the shop.
17. 
    12 Apr 2005 ~ 10:05pm Unregistered Thanks for your instructions, but I need more help. I did as you suggested with the exception of taking off the CPU. However, I put it back together after cleaning, and I can hear my computer come on, and the fan runs, but I get nothing on the screen (as if only the electrical parts are running). Do you have any suggestions?
18. 
    8 May 2005 ~ 11:10am Unregistered Excellent article .. my friend's A30-141 had the same problem, shutting down unexpectedly and following your instruction .. lo and behold, a think layer of dust stuck between the heatsink and the fans. Removed it and now the problem seems to be gone away. Thanks a billion for the article again.
19. 
    16 Jun 2005 ~ 11:24am Unregistered Wonderful. Thank you for helping me solve this problem. I removed the heatsink from my A35 and boy was it covered in dust. Thanks for taking the time to write your quick fix article. - Eric

    30 Jun 2005 ~ 5:02pm Unregistered What a fantastic well put together article as i have a Toshiba A30 as well and i will print this off and follow the steps, the web-site is superb as well and very well put together. A big well done to you.
21. 
    8 Jul 2005 ~ 9:02am Unregistered Thanks to the article my Tosh A30 is now running a lot cooler, I am surprised that Toshiba have not taken more responsibility at what appears to be a design flaw.
    Much appreciated
22. 
    12 Jun 2006 ~ 5:03pm Thank you EVER so much for going to the trouble of writing this article. I've been having shutdown problems for so long that it seemed 'normal' and the fans were on constantly (when the laptop (Toshiba A30) actually worked, that is). Having cleaned the heatsink following your advice, the fans now sometimes turn *off* and I can actually use my laptop without propping it up at the back. THANK YOU!!!

    31 Jan 2007 ~ 12:25am audsnends Found your article searching for information about over heating Toshiba laptops.
    
    I did it!!! Naturally taking it apart was easy, despite driving all over town to find a torx bit #9, had to settle for a #8. Then dropped one the screws inside, lot of shaking going on as it managed to wedge itself, so had to loosen a couple of screws on the casing to get it out. Cleaning went fine, it was filthy as I have a cat that believes my laptop fan is her own personal heater. And as you mentioned in your article my processor is permanently affixed to the heatsink.
    
    The nerve racking part was after putting everything back together my laptop wouldn't quite start. Opened it again, somehow I'd managed to bend two of the pins. Using a magnifying glass & dental tool to straighten them, and after four more tries adjusting the unit...VOILA!
    
    My laptop is sooo quiet now...should be able to run some programs completely now, thank you!

    :celebrate Terrific, audsnends! I'm happy you were able to get it cleaned out and up & running again. As you discovered, laptops can be tricky business when taking them apart. You did well on your 1st venture into your laptop's innards. :woowoo:
    
    Re: kitty camping out in front of your laptop fan vents, it's very important that all the vents on your laptop are unobstructed. A laptop can overheat very easily because all the electronics are enclosed in such a tight space.
    
    Perhaps a heating pad slid under a towel and atop a pillow would suit kitty even better... I have kitties, too. (In fact, I'm currently typing one handed while I hold my youngest in my other arm) They've all made it clear who the boss is not. Kitties being who they are, I suspect the same holds true for you as well. Even so, perhaps the heating pad (in close proximity to you of course) might be a sufficient bribe to get kitty away from your laptop vents. :smiles:

    18 Mar 2007 ~ 11:58pm catrebligtx THANK YOU THANK YOU THANK YOU for this article. I used to take my A35-S159 in for repair when this happened since it was under warranty. But now that I would have to pay for the work myself, I figured I needed to learn how to do this myself. I can take desktop computers apart and put back together in my sleep but this is the first laptop I've owned. Like some of the others who responded to this, I dropped screws inside the laptop and got a blank screen when I turned the computer back on. But it's working now, and it's great. I thought I was doing something wrong when reassembling but then I found this article that indicated that the cpu won't go back in with any resistance. I spent over an hour trying to get it back in thinking it was supposed to resist. So again, thank you. This article saved me a whole lot of time and frustration.

    12 Jan 2009 ~ 3:15am Mike Great howto, works perfectly. Just did it to my Toshiba Satellite for the first time since I got it 5.5 years ago. I'm pretty sure the performance is improved and it's definitely running cooler and quieter. I had to make due with a T10 instead of a T9 bit... if you do this, try to have the right tools on hand!
30. 
    1 Feb 2009 ~ 2:22pm NorahBatty I was delighted when I found this article as my Toshiba A-30 was behaving just like all the others mentioned here. It is almost five years old. I did everything in the article but when I put it together again power came on but nothing else. The HDD light blinked once then went off. Went through process again and found one pin bent flat in the corner. Didn't have a dental tool like Audsnends but managed to lift it upright with a sewing needle. Only problem is it still has a curve in it. I'm such a neophyte I don't know if I should attempt to straighten the pin myself. How robust are the pins? Would it withstand using a tweezers to straighten it? Can anyone help please? The CPU seemed to move a bit on the paste but since it went back in o.k. I figured I had lined it up correctly but maybe not. I do hope I can get help on this as I reallly don't want to have to spend money bringing it to the repair shop.

    22 Apr 2009 ~ 1:05am Phil Hey, I have had my lappy shutting off like crazy, and now i know it isnt just a piece of crap, it is overheating wow!
32. 
    18 Jun 2009 ~ 7:34pm Yaf Hi,
    I had the same problem, my laptop is less than a year old. It would shut down after long periods of simple surfing, however whenever i tried to play a game it would shut down after about 5-10 mins.
    
    I tried opening up the laptop, Satellite A300D but it was a little more intimidating then i thought it would be so i settled with blowing pressured air through the fan outlet and all the other openings and that seems to have done it for me. Now can feel alot more air coming out and its still cool after 30mins.
    
    worth a try before opening it up, but thanks for the info.
33. 
    28 Jun 2009 ~ 9:56am Jay Thanks, great guide
34. 
    4 Aug 2009 ~ 9:06pm Marty The CPU is definitely NOT glued to the heatsink.
    
    The thermal paste may be dry and require heating up with a hair dryer and sliding a razor blade between the IHS and the heatsink.
    
    Mine didn't even need this. Simply prying it off with a credit card did the trick. Cleaned it up, applied Arctic Silver 5 and put it all back together. No problem. No shutdowns.
35. 
    4 Aug 2009 ~ 9:09pm Thrax It entirely depends on your heatsink, CPU, manufacturer, thermal grease, etc. Some thermal adhesives, particularly from OEMs, are part adhesive, part TIM.
36. 
    12 Sep 2009 ~ 6:59am Mozzman If you own a Toshiba and your having this problem, theres a very simple solution. Sell it and NEVER buy a Toshiba again. Overheating is a very evry common problem with Toshiba's for one of 2 reasons. 1. They dont know how to cool thier systems properly or 2 they consume way too much power overheating the CPU. I have run comparison tests with Toshiba's, Asus and HP laptops and found that the HP and Asus laptops would run at about 30 degrees celcius while the Toshiba ran at around 70. This was sitting idle. If you pushed it, the HP and Asus would reach around 40 degrees while Toshiba could get up to 100 and switch off. Its simple, stay away from Toshiba's as they have no clue how to build a laptop. I have an A70 and an A200 with the same overheating problem and have many clients with the same issues.
37. 
    2 Oct 2009 ~ 10:45pm Aaron I don't have any thermal paste, canned air or isopropyl alcohol. I know I could troll about town finding them, but I'm just wondering if I can take the heat sink out, remove the bulk of the dust like a clothes dryer filter and put it back in without dealing with the paste etc.
    Is that an OK temporary fix? I'm not really confident with hardware
38. 
    3 Oct 2009 ~ 1:14am Linc You can get by without the canned air probably - just suck it out with a vacuum. The thermal paste is ABSOLUTELY necessary if you remove the heatsink from the processor (you will DESTROY your computer if you don't re-apply paste afterwards), and isopropyl alcohol is like $1 at the corner drugstore.
39. 
    22 Oct 2009 ~ 9:44am Will T Thanks so much, this solved my problem after I had spent countless hours trying to fix an overheating A30

    24 Nov 2009 ~ 1:33pm Armagan D. Greetings from Istanbul. Thanks a lot mcwc. I wouldn't have dared to touch any screws on my laptop if it weren't for this article. Having summoned my courage here, I found this: where they provide a hardware maintenance manual for IBM-LENOVO 3000 N200 (and N100) series . This manual makes stuff really easy, provided you read it thoroughly before you begin and follow the instructions verbatim. I cleaned a ton of grime and dust from my fan and now everything's good as new. (The only thing that made me a little uneasy was Lenovo's strict recommendation about using a set of screws, which are all nylon coated, only once. But who gives a flying ... !) Cheers and thanks again
41. 
    24 Nov 2009 ~ 1:37pm Armagan D. Ooops! The web addresses I posted in my previous comment are sifted out. You can still get there from here. The title of the page is: Lenovo Support & Downloads - Hardware Maintenance Manual - Lenovo N100 (type 0689, 0768), N200 (type 0769). Just google it to download a 13MB pdf manual.
42. 
    28 Nov 2009 ~ 9:16pm Frank W I've had my A30 for 5 years and it recently started freezing occasionally (a total halt or freeze type crash), usually when using Firefox. Updated RAM to 2 GB about a year ago, RAM seems OK.
    
    Thanks mcwc, I used your info to clean the slightly dirty heatsink. Btw dental floss good for cleaning heatsink. Maybe the cleaning will get rid of the freeze. I saw some dust on cpu pins, maybe it was causing static & the freeze.
    
    I read elsewhere that static electricity can cause freeze in A30 & similar Toshibas. Toshiba has a cure with a little mod but I don't have details.
    
    I still like this notebook so might put in a 320 GB HD - WD WD3200BEVE.

    2 Jan 2010 ~ 10:41am Chris This is a great method of getting your laptop back into working order. One tip for anybody who gets it all back together to find the machine won't boot, don't forget to lock your CPU after you put it back in. If it isn't locked it won't boot.
47. 
    16 Feb 2010 ~ 11:36am Sam Thanks for the article. Dead useful.
    
    I found that when I put everything back together it wouldn't boot (see other posts above, black screen, fans whirring but nobody home etc).
    
    Spent half an hour cursing before realising I hadn't unlocked the CPU in the first place. Go back in, unlock it and lock it back in. Booted up first time.
    
    Thanks again

    THank you for your attention.

    19 Mar 2010 ~ 3:35pm bren Great article. Thanks very much. The cleaning went just fine. However, I can't get the processor to seat properly despite multiple retries. It seems to be lined up OK and there are no bent pins. The machine won't boot up. Maybe the overheating has already damaged it ?. Again, many thanks. Best wishes, Bren.

53. 
    21 Sep 2010 ~ 6:37am AnswerMan I think the answer to the below is that some pins probably were bent in putting the part back in. at least that is what happened to me.

    25 Nov 2010 ~ 2:38pm NTTS Much thanks for donating your time to give this very well laid out article. I had a custoemr come in with an older laptop, (unable to run a recovery) and after checking DVD drive, media, and BIOS settings, this was the fix! I just wish Toshiba had a CPU temp reading so I could have skipped all the troubleshooting (it took over 40 min of use bfore the computer would start powering itself down/pointing to a heat issue)! years later, your info is still golden. keep up the great work.
56. 
    25 Nov 2010 ~ 2:42pm NTTS PS: When putting the CPU back, hold the laptop up and look through the air vent to line up the pins. Do NOT put any pressure, but wiggle it back and forth a little. If you do bend a pin, bend it back VERY gently witha screwdriver (be very picky, make it perfect). Lastly: instead of any liquids, I removed the dustball by hand, and used a can of air to clear the remaining debris from the heatseink. Thanks again!

    10 Feb 2011 ~ 5:18pm MeMeBev I can not get the cover off my heatsink on my toshiba satellite a25-s159. I take the screws out and the corner lifts but resists about 1/3 the way. Trying to open to clean as it is doing just as discribed above. Had it almost 7 years, runs well still..just a bit slow.

    29 Dec 2011 ~ 7:13am Aida My hp 520 was shutting down spontaneously all the time. I've cleaned the heat sink and cooling fan. My desktop got corrupted and I lost a lot of data because of the constant shutting down and my efforts at restarting - i think.
    I took it to a local computer repair shop and after £60 for reinstalling software, retrieving data, it's still shutting down all the time. What could possibly be wrong? I am a student and can't afford to pay any more.
63. 
    29 Dec 2011 ~ 12:13pm Tushon HDD could be going bad. Easiest way is to shutdown, pull HDD out to verify manufacturer (as in, Western Digital, Seagate, Hitachi, etc), download and burn UBCD to a disc/USB, and run the manufacturer test after booting from that CD/USB. Personally, I recommend the manufacturer test AND Hitachi's Drive Fitness Tool (long test).
    
    If it passes both tests, then you can also try just running chkdsk (windows key + r, chkdsk /r in the box, type y to schedule a chkdsk for next reboot, and reboot) to see if it was just some software issues.

    22 Feb 2012 ~ 2:02pm Fred Hi great read, really appreciate your efforts!
    
    My issue is that I do not want to let go of my A30, obsessive compulsive I am sure, however, I want to upgrade, various components, so it is fast and more reliable and up to date almost alongside today's units. But everyone tells me it can not be done! I don't think that is true, I mean I am sure it can be done it just may be difficult and I might have to make some room in the unit or something. I just find it hard to believe that all of today's computers are thin and components are getting smaller than ever, and that I can not find compatible parts to install, that are either from other labels. Or maybe I just have not talked to the right people or found the right forums or websites hence this comment :0)
    
    Can you please help?
    
    Best Regards
    Fred
    
    P.S. if your wondering? Is it capable to replace the motherboard, HDD, CPU, and basically everything else.

    16 Jun 2012 ~ 1:27pm Richo The heatsink in my Toshiba was almost the exact same as pictured here! Thanks for the great advice

    20 Aug 2012 ~ 9:13pm Cody SOMEONE PLEASE HELP ! ! my acer Ferrari 5000 laptop cant operate for more than 5 minutes after starting. Its shuts off just like that. Then when you restart again it shuts off when booting and the shutting off time gets shorter again and again. I've tried all these great advice - cleaning the heatsink with a brush, removing the thermal paste build up and cleaning surfaces etc.etc. but this seems to be an extraordinary problem. What could be wrong please ? ? ?
67. 
    21 Aug 2012 ~ 8:39am CB Have you tried running the system (from cold) elevated? Prop it up on a couple doorstops or something else that would leave breathing room under the system, and see if that extends it's time running. Maybe even try an icepack underneath - just to see if that's the problem, not as a permanent solution.
    
    If it is heat, then you may not have reseated the heatsink on the CPU properly. That can make a CPU get hot real quick.

    SOMEONE PLEASE HELP ! ! my acer Ferrari 5000 laptop cant operate for more than 5 minutes after starting. Its shuts off just like that. Then when you restart again it shuts off when booting and the shutting off time gets shorter again and again. I've tried all these great advice - cleaning the heatsink with a brush, removing the thermal paste build up and cleaning surfaces etc.etc. but this seems to be an extraordinary problem. What could be wrong please ? ? ?

    Also, you said you removed the thermal paste and cleaned the surface, but did you apply new thermal pads after? As CB said you may not have good contact with all the surface that need cooling. If you did, did you use thermal paste or pads when resetting the heatsink? I would recommend pads because not every chip surface will match up exactly with a heatsink and the pads are a little more forgiving.
