When the CPU overheats then it will shut down (i.e. thermaloverload) and won't boot up again until it has cooled down. If this is theproblem is not fixed then the CPU will eventually fail.
A faulty fan causes the problem or the fan and heat sink assembly are cloggedwith dust.
Check the CPU fan to see if it spins freely, if not replace the fan.
If the fan and heat sink is clogged with dust the remove the dust and make surethe vents are clear and dust free. Use a can of compressed air to do this.

Your power management in Windows is corrupted. I would do a system restore to an earlier date.
Click Start, point to All Programs, point to Accessories, point to System Tools, and then click System Restore.
On the Welcome screen, click Restore my computer to an earlier time, and then click Next.
On the Select a Restore Point page, select the date from the calendar that shows the point you'd like to restore to, as shown in Figure 2, and then click Next.
Figure 2
On the Confirm Restore Point Selection page, verify that the correct restore point is chosen, and then close any open programs.
Click Next if you are ready to proceed or click Back to change the restore point.
The computer will shut down automatically and reboot. On reboot, you'll see the Restoration Complete page, and then click OK.

If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.
Thanks, Joe

There are several reasons to this problem but the first reason may be because of over heating problem therefore just check the processor fan whether it is running in its speed or not.

Just put the heatsink paste in the processor which also may solve the problem

SOURCE: My Toshiba Satellite A75-s206 shuts down by itself.

Yes, it could be, but it could also be that your heatsink that sits on top of the processor has come loose, therfore it cannot transfer the heat to all the little blades for the fan to blow on to keep the processor cool. So, the processor overheats, making the computer shutdown automatically to prevent from destroying your processor.

This is a safety feature that most computers have, however, if your processor keeps overheating over and over, you could destroy it, so for right now, the best thing to do if you have to use your laptop is to stay away from programs that use the processor alot, like games, and video players or editors.

My laptop gets way to hot and turns off.

Keeping the fans clean is especially important, because the fans blow out hot air and bring in fresh air to cool down the laptop.

Fans attract dust, however, which can slow them down, resulting in a hot laptop.

If the laptop overheats, vital parts can cease functioning altogether.

Consequently, keeping your laptop's fans clean is crucial.

check you CPU make sure its securely seated and has thermal grease

hope this helps

I turn the compute on and last for 2 minutes and the it turns off itself, I want to know why

Theres not enough information to properly tell you. But I would start with looking to see if your fan turns on when you turn on the computer. If the fan does not turn on then your CPU overheats and the computer will shut itself off. To try and fix this, clean out the fan (hair or anything around the fan motor can prevent it from turning).

It gets very hot and turns itself off. I took it apart and cleaned all dust and dirt away... it is really clean now! But when I turn it on again the fan works a little and goes off... after a while it...

The problem is with your Cleaning!
I think that you've removed the Heat sink and wiped off all the Thermal Paste off the processor while cleaning the laptop.
Please don't switch on your computer the processor could get damaged. To solve this Purchase Thermal Paste appropriate for your laptop from a local store and apply it carefully on top of the processor and install the heat sink above it firmly this should solve the problem.

My laptop is running very hot and keeps turning off although the screen is not black but blank. I have a Toshiba Satellite L305d-s5881. Thanks!

The Toshiba Satellites were will known for heat problems, the bottom of the laptop needs to removed for access, the cpu fan, heat sink, must be removed for cleaning, when all dirt is removed including the fins. Clean thermal conductive grease off the heat sink and cpu ic, apply fresh and assemble, if not sure get a professional.

Toshiba Satellite A100 LE4000 Turns Off Randomly

there must be still a problem with your current cooling system. try cleaning up your laptops fan. cpu gets heated up very easily even if you turned it off for a while. you can do this by unscrewing the parts, the inside must be pretty dusty or something. this also happened to me but from a different unit.

also, try checking for the latest bios driver for your laptop and to be sure, download it on toshiba site itself. because latest drivers for your bios also manages the control of your cpu fans.

if you could also get access to your systems cooling options in bios, try checking if your cpu's temperature are doing fine.

but i prefer you cleaning up the inside fans as well. hope this helps.

Laptop (Toshiba Satelite A60) keeps turning off

Is it turning off by itself after being on for 20min... each time? I.e. is it consistently turning itself off after the same amount of run time? Check the bottom of the laptop... how hot is it? Might be an over-heating problem. Some freeware (MobileMeter) might help you monitor temperatures and see if it is a problem


Some excellent heat management information here:
