The laptop is dual-boot Windows 7 and Ubuntu. After updating Ubuntu to 11.10 a sudden started rebooting. (perhaps no more than a coincidence)
The symptoms are the following: the independence of the external reasons for the laptop suddenly turns off (like if you hold down the off button) and after a second or two begins to load. Described occurs both in Windows and in Ubuntu. And if Ubuntu to listen to music or watch a video, then restart is not happening. (to the extent that if you turn the music off, then after a short time restarts, cost while aplay /dev/urandom) In Windows the music does not produce this effect, i.e. when the music restarts, the same happens. However, if you run a heavy game, it reboots almost not happening. (e.g. hours-long gaming session in Skyrim occurred without interruption for reboot, although once when reading the books the reboot occurred, however, after installing updates, restarting has started to happen during the game) in the selection menu grub reboots not happening.
The temperature of the equipment beyond reasonable limits (measured immediately after the reboot), run a memtest'passes without errors.
This is all done with the power cable because the battery is exhausted and does not hold more than an hour of work. Taken out battery, restart same happen. On one battery reboots apparently not happening. With a new battery and another power supply everything was exactly the same.
Don't especially like to carry a laptop into the service center. What you can try to restore the normal operation of the laptop and what might be the problem?
Random rebooting can be caused by local overheating (dried up thermal interface and the motion of the crystal body instantly overheats in a small area) — it is in the EEE PC 901 — treated by dissection and replacement thermoprotei garbage (I thermoprotei glue put the copper plate).
While the first time didn't clean the cooling system and not smeared thermal paste — the system could not tell the cause of the fall, and once smeared thermal paste — had to say that critical overheating (although immediately after reboot the temperature was normal).
That as an option.

And try the energy saver setting to disable the "lull hard disk when idle". It seems when hard goes to sleep You have a computer and restarts. Well, or with another hard drive machine.

Freezing, obviously. Urgently wrapped in a towel!
In General, a couple of times is met on dextop, how to logically explain not know, but always helped change the PSU, maybe the track which is cracked on the motherboard of the laptop...

Can be bhed on the screw. You have probably disabled BSOD in the BIOS, in any case, in Windows there is a log krasev. There you can see what the error is. Maybe something out of IO
