Trying to diagnose what's failing in my PC. Srdjan Aug 17, Ask a Question. Replies 2 Views Aug 18, Srdjan. Latest posts. The line is about the thickness of a thread. John, It might be the LCD screen problem.

There is no way to troubleshoot it, until you connect a test LCD screen and check if it fixes the problem. Thanks, cj I was hoping someone might say that. The LCD solution seems right. At worst right now it is only annoying. CJ, I took your solution and went to my local computer store and picked up Ceramique an Arctic Silver product. Could I have damaged my processor? I noticed that when I cleaned the surface of my CPU isopropyl alcohol it seemed just a tad discolored at the center, whereas around it there was a nice, mirror finish.

I opened the panel and ran my computer again. The brass directly in contact with the CPU is hot, but the heatsink out where the fan blows air is cool.

Thanks again, CJ. I think my Toshiba M45 Satellite is overheating. It freezes after a minute of the computer being on every single time. I am planning on getting compressed air to clean out the fans. If that does not work, is there a tutorial on how to apply artic gel, or to remove the fan to celean out more?

I do it myself each time I have to reapply thermal grease on a CPU. Does the fan spin all the time or it starts only on the laptop start up? If the CPU is so hot, the fan should run at least once in a while. Just yesterday I had to repair a similar problem on Toshiba Satellite A The laptop shut down after minutes being on.

The heatsink was very hot and the laptop shut down. Apparently, the circuit that turns on the fan when the CPU is hot was bad and the problem was fixed after I replaced the board. Another laptop with a similar problem I fixed about 3 days ago. Fixed the laptop by replacing the fan. So, check for fans. Arctic Silver makes a good stuff and by the description they provide, Ceramique thermal compound is a good one.

I was watching a power point file and it just repently started going very slow, so I restarted it and it was doing the same thing, and restarted it again, but it never did.

I thought is was a virus, so I took out the hard drive and connect it to my desktop, but it runs perfect and no virus found. Then I thought it could be overheating and I cleaned it as the procedure you show in the website, it stills the same. One particular thing is that the time never change, not even in the BIOS. Any advice???? Could the battery of the BIOS be causing this??? My fan seems to be doing fine. It starts up about thirty seconds into startup, and it blows at full speed.

No odd sounds or anything. I would definitely test the hard drive. You can use Hitachi Drive Fitness test. If it passes the test, I would back up all important data from the hard drive and then run a Toshiba recovery DVD to take it back to factory defaults.

It might be a software problem. Thanks for your advice CJ, I actually did that already, talking about the buckup my important information…. Thanks for your help. It would be. You follow this wizard to create a bootable floppy disk. I think that for Satellite A75 you can create only a bootable floppy disk, not sure though.

After that you will have to boot the laptop from a USB floppy drive and finish it up. After you reboot the laptop you should have new version of BIOS. When you upgrade the BIOS, you should run the laptop from AC adapter power, because if the battery is not charged and it dies during the upgrade you might have a problem. Hi, I have an AS laptop and it overheats after 10 minutes and turns off. It started this about 2 months ago and would only shut down after about 1 or 2 hours of being on.

Do you think this is a dirty heatsink problem. If so in your dissasembly instructions the last two steps are removing the CPU. Will i have to remove the CPU to clean the heatsink. Thank so much for the site. I will be donating by paypal! Most likely just cleaning the heatsink would be enough to fix overheating. Also, check if fan spins when you turn on the laptop. It should start spinning right away after you turn it on. In some cases laptop overheats because of a dead cooling fan.

BTW, I like your idea with paypal. A couple of last questions c. Where should I look for the dust. Also what email adress should I send the donation through paypal. Man you are a life saver. I followed the instructions and man was that thing dirty. It was like a big ball of lent over both openings to the fan.

I used a shop vac to get the dirt out then I followed the instructions and applied Artic Silver to the cpu. Ive had my laptop running for at least 2 hours now and its as cool as can be and doesnt shut off.

I hope a 5 spot will due for a donation until I get paid. Again thanks so much I will tell all my friends about this place! Hi there, I tried the idea above of vacuming out the vents from my Toshiba laptop, as my lap top too was shutting itself off everytime i tried to play a game or watch a dvd, and it had neever done this until now. No shutdown! I advise anyone with the same problem with any kind of laptop to try the same.

Great tip thanks alot, saved having to take it to a pc store to get it sorted. What can I use to keep the fans from spinning that is non-conductive? We had an overheating problem with our A Now, the computer boots up, however the fans are not running.

If you could help address the fan problem first I would be most grateful. Any any ideas on the display problem would be much appreciated also.

Judy, I am not an expert but when you took apart the computer and unhooked the display cable there was another black wire secured by a screw. This is a ground make sure you hooked it back up properly. And about the fans cj will probably know the answer to that and the display problem.

Just thought i might add a little advice! If you experience the same problem as I described in the post, try to blow off the fan first. I usually take the fan out and block fans with my fingers. Judy, Did you plug fan cables back into the system board? In Satellite A75 there is no way to plug them back without taking the laptop apart. Satellite A75 fan has 2 fans and 2 connectors. May be you plugged in only one of them? When you turn on the laptop, both fans have to start spinning.

You can see fans through the grill on the bottom. Do they spin at all? It has to be secured by F3 screw located under the keyboard. I have an AS Is there anything else I will need to do ie. Thanks cj. No drivers needed. Whe I go to properties of my PC running is safe mode is really wird that the speed of my procesor is showing as I think the procesor could be damaged.

Any ideas?? I would really apreciate it. Still on the fritz, and my fan looks like its working just fine. Here are a couple guesses. Wrong thermal grease. I would contact the manufacturer and ask them if you can use the grease with your CPU. Usually fans spin at different speeds. May be your fan works only at slow speed. The fan is controlled by the motherboard. The heatsink is not seated properly and there is a gap between the heatsink and the CPU surface.

Just kidding. What speed does it show? As soon as you turn on the laptop, pres on ESC key. The laptop will continue to boot with details on the screen. You should be able to see the CPU speed. If the screen flashes too fast, you can pres on Pause key.

What CPU speed you see? My laptop toshiba as, will not power on from ac or battery. So I think power manager chip is dead? Toshiba Guy, If Satellite A75 will not boot from a good AC adapter of from a good charged battery, then I would say something is wrong with the systemboard.

Not sure about power manager chip, I do not repair motherboards on component level. Do you get any LED activity at all? What are your symptoms? Do you hear any sounds? Have you tried to reload Windows at all? Should I trhow it away already?? Do you know where to get a restore cd for a satellite AS I cant find it on ebay and I have lost mine.

Call Toshiba customer service line at and ask them if they can sell you one. You can see them through the grill on the bottom of the laptop. If both fans spin and they are not noisy, wait with the replacement, try cleaning the heatsink first. A powerful air compressor would be a better option. Thanks guys. I will follow your advise and focus on cleaning the heatsink and get back to you on the results. I have a AS model and I had the same problem described here laptop is on for mins and turns off without warning.

I already cleaned the heatsink and the fan and assembled back the laptop. I tried everything including disassembling and assembling again but it did not work. I did not bother putting any coz I thought it was just dust. What do I need to put in there? Joseph, Yep, this gray stuff on the top of the CPU is thermal grease and before you assemble the laptop back, you must apply new layer of the grease because the old one is already removed. If you run the laptop without thermal grease, it will overheat and shut down.

You can buy thermal grease in any local computer store or buy it online. When you assemble the laptop, make sure that both fan connectors are plugged into the system board. So I ordered a new hinge and put the computer back together in the meanwhile. Of course, the computer overheated. So I went out and bought Ceramique thermal paste, and followed their online directions. The first time the computer overheated, the fans were on full blast for a while.

It overheated within I believe 30 minutes or so. All of a sudden, the fans went on full blast and the computer shut down. From the fans turning on to the computer shutting down was really quick, within seconds…any ideas what to look for? I decided to retry applying the ceramique paste. I bought acetone, and thouroughly cleaned the heat sink and the CPU.

So this time, I cleaned both parts really well, and followed the ceramique instructions very carefully. The computer is still overheating. I believe it should be in the range, correct? I called Arctic Silver, and their very helpful tech instructed me that some laptops require a thermal pad for the heat sink to make good contact to the CPU.

I called Toshiba, and their not so helpful tech stated that according to his specs, Toshiba uses pink silicon grease, not a thermal pad. According to Toshiba specifications, Toshiba Satellite A45 requires a pink grease. I would probably try using the grease recommended by Toshiba. I was very surprised that with Arctic Silver grease my desktop ran 10 degree C hotter then with grease that I got with the heatsink. Since then I use grease that came with the heatsink. From your knowledge, is there anything special about this grease?

Do you know if Compusa sells anything that I can try? When we were out of pink grease, we used just whatever we had in stock, some kind of generic white grease.

Let me know how it goes. What else should I be looking for? Do you know the version of the laptop BIOS? Version 1. Are you sure that laptop shuts down because it overheats? Also, I downloaded a freeware called Speed Fan or something like that, and it shows temps idling in the 60C range, and then when I do something like watch a DVD, it creeps up.

When it hits around 82C, the PC shuts down. I think you should sell the laptop to somebody who lives in Alaska; at least they can use it as a heater. Can you see if both fans spin? I have a TE and I have this overheating problem too.

Do you know where I can get the Toshiba pink grease cheaply? I live in Singapore. Apply just a small drop, just barely enough to cover the CPU surface after you spread it. It had a overheating issue. Blowed the dust seems to fix that. The lines are kind of cm long. I tested the graphic card with a external LCD..

No Lines apear ever. So I opened the top lid that coved the connector of LCD to the motherbord. Tapping that connector seems to remove the problem temporarly. Is there a way to fix this issue? Replacing the video card? Is symptom of cold wirring? CJ, Thanks for the help, I did finally get the computer to work. I had ordered a new hinge, and figured that I might as well fix the hinge and worry about the overheating later.

So I fixed the hinge using your wonderful tutorial thanks man! I cleaned the heat sink and CPU again, this time for like a solid half hour. Yes you can change the Processor from an Celeron to a P4. Now the bad part. You must take the computer apart to gain access to the processor and remove fans, heatsink and processor. You will need new thermal grease to re-attach to heat sink. Now the most important part to remember you must find a compatable P4 that has the same or lower wattage rating than the Celeron.

I changed a Celeron 2. Good Luck. I need to dis-assemble the unit anyway. I had an overheating issue with this machine. I found your website and followed the directions to clean it. I was thinking this would be a good time to up-grade the processor since I have to dis-assemble the unit.

You assistence is greatly appriciated. I was able to locate a 2. It requires the same wattage as my 2. Will it still work? The thermal design power for both processors is I will also be placing a triple 60mm fan cooling pad under the machine.

Does anyone know where to buy or replace an LCD screen cheaply for a toshiba ps? Any suggestion will be really helpful. Thank you. You will find a new lcd for this laptop on ebay or amazon very cheap. Or you can order from toshiba for an extremely high price. If you are interested in selling your damaged screen let me know. My TE will occasionally shut down by itself, so I thought it is due to overheating. However, I took out the HSF and did not see any clogging. I assembled everything and switched the laptop on, but the temperature is about the same as before.

AS5 needs some time to perform optimally, so maybe it is due to this? I used a program called MobileMeter to check the temperature. It ranges from 60 to 64 degrees Celsius. Is this OK? I have dealt with the overheating issue on my A too, but my problem now is that it keeps restarting and going to the Windows Advanced Menu. Hi I have a fan problem with my Toshiba Satellite Pro The fan also starts when i start up in bios upgrade mode. I have a s I used to have the overheating problem but fixed it by cleaning the heatsink and every few months thereafter cleaning it.

My problem now is when I plug in the dc power adapter sometimes it shows it charging and sometimes not. When I wiggle a little the light goes on to show it charging. Sometimes it stays like this for a long time and sometimes I have to keep playing with it for a while. I read about the plug coming apart from the motherboard and re-sodering it there can fix the problem. If I want to check if this is indeed the problem do I check from the back of the computer or do I need to disassemble the front which I have never done before and am not quite sure how to do.

Thanks for any help or advice. Wayne, I think that 60 degrees Celsius is a little bit high. Steven, Did you take it apart for cleaning? If the laptop worded fine before you cleaned up the heatsink then check if all cards and connectors are seated properly.

It keeps shutting down randomly. I checked the heat sink and cpu and its clean.. When it shuts down, the power light button stays lit but the screen is black. My battery charges fine. When the laptop shuts down sometimes it takes a few tries to get it to boot again. Some times it boots on the first try. Sometimes the laptop will stay on for hours and sometimes it shuts off after a few minutes.

Do you know what the problem could be? Thank you for your help. I guess that the temperature sensors might not work properly and the fan will not turn on when the laptop is hot. Not sure though. Let me know if you find a solution. The booting up problem existed before I cleaned out the heatsink. I plugged the hard drive into another computer as an external and can read it fine. I tried using Linux suggest in 34 to reboot from disk and even with failsafe it gets a kernel abort.

I also have this model toshiba satellite ps with the exact same problem. It began to shut off unexpectedly about 4 months ago, I took it to the service and they told me the problem was in the heating system and also maybe the hard drive. They told me that they fixed the problem and it did begin to work normally about months and now it again began to shut down, sometimes even only log off and sometimes start again by itself.

I took it to the service again and after a week of diagnosis they now tell me that something is wrong with the motherboard and it is a common issue with this model. I do not know what to do know. Are there any ideas? Ajit Vamadevan Honorable. Dec 10, 1 0 10, 0. I tried to get it fixed by tech but in vain , he says he haven't seen this problem even once. Joeslim Honorable. Jan 3, 1 0 10, 0. Im having the same problem , ive got this toshiba a which is quite old , now its shutting off randomly when u turn it on but when i go safe mode it stays , i ran linux and it shuts off after couple of minutes but when i run in compabitliy mood it didnt do it , i have tested the hdd and ram and all good , so i suspected the graphic card driver or maybe another driver , i updated bios and installed the original windows that came with it ,so far no problem but only two drivers in the driver list still not installed and i also noticed , the network driver had some weird name "isatap.

If anyone have an advice or can have any knowledge about what is going on let me know plz. Jan 6, 2 0 10, 0. Have same Problem with toshiba equium ad turned it on and after a minute or 2 the fan would go real loud and the laptop would just power off ,tried updating all drivers and the bios ,tried reinstalling windows and same thing kept happening, i then took the laptop apart and cleaned out the fan that did not work i was thinking of replacing the thermal paste but when the fan came on the heat was coming thru so i went into power options and into advanced power options in boat battery and plugged in and went into processor power management and brought the maximum processor state down to 80 percent the fan still runs all the time but it no longer shuts down.

Spar parts can be had on eBay by either buying the part at a marked up price or bidding on another machine being sold for scrap that has a different problem. Throttle Stop to force different states on the cpu when the need to reduce its speed if temps remain high. Jan 16, 1 0 10, 0. Same issues with my brand new Toshiba. I have only had it a month and a a half.

Sounds like Toshiba has something they need to fix. Unfortunately their staff is completely inadequate to handle such a situation and does not keep track of their callers.

I bought mine direct from the company and it has been an everyday occurrence at least twice a day. My computer is not over heating because it doesn't even have the time to warm up.

I am fed up with it and am fighting for reimbursement. Good luck to anyone having the same issues. Michael Miller Honorable. Jan 24, 1 0 10, 0. Feb 12, 1 0 4, 0. I had this problem back in August. I took it to a Toshiba Authorized Centre and he said he'd never heard of a sudden shutoff.

He cleaned out the fan and vents and said the laptop was fine. It's been working fine--until three days ago. The laptop started to shut down at random, twenty minutes, six hours, 12 hours. The underside and side vents are still cool to the touch. It was good for four months, and here I am again.

Any new thoughts? Thanks for your feedback, it helps us improve the site. In reply to Vijay A. Verma's post on December 22, Thanks for the reply. Resetting the battery was going to be my next step. Problem with the other options is it won't stay in Windows long enough for me to be able to run anything. I believe I can change the power options and fast start up from the bios screen though because it won't shut off when I'm in it.

If yes, come out of this and start normally. Thanks for all your help. It will not not to safe mode. Tried resetting battery, did not work. I was just thinking it has to have something to do with Windows itself because when I boot up to the login screen it'll stay running, but when I log into Windows, it'll shut down in the 15 to 30 seconds.
