If your notebook is experiencing BSODs or complete shut-downs then the culprit be a dusty, dirty CPU and heatsink. This means it's time to clean it and gain back stability. Just how to do it is what this guide is all about.
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.
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 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.
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.
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.
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

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).
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!
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!
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.
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?
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.
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
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.
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
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!!!
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:
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.
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!
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.

Thanks to Matt for editing the guide and getting it to MM.
Thanks to MM for getting it up.
Good article though
Thanks for taking the time to comment. We do appreciate it.
