The cpu get overheated and will shtdown to protect it. The fan continues to run until a CPU safe temperature is reached / sustained.
1. Use laptop on flat surface, not on pillow, carpet, bed, etc. that will restrict air flow. Using a can of compressed air, clear the air vents.
2. If the symptom continues, then the heat conductive paste between the cpu chip and the heatsink is no longer effective (hardened, too thin, etc.). Remove the heatsink and add thermal paste
($6 Radio Shack).
Hi..
If the laptop shutdown maybe it cause overheating.
Laptop shuts down? Computers may not be smarter than people, but if
they’re designed properly, they will shut themselves down before
overheating to the extent that they do themselves damage. If the smart
person keeps turning the notebook back on and figures out a way to foil
the protection, the laptop is probably doomed. Once a laptop shuts down
for thermal event protection, it may refuse to power back up for a
fixed period of time, five or ten minutes, or it may begin to boot and
shut down immediately as soon as it boots to the point that it can
figure out that its too hot. The over-temperature protection is
generally a BIOS rather than an operating system function, so one sign
of an overheated laptop is one that shuts itself down while you’re
using it and then refuses to boot as far as the operating system unless
you leave it alone for an hour or so to cool down. Unless you’ve been
working in a very unfriendly environment, high temperatures, direct
sunlight, etc, you should take even a single overheating shutdown as a
warning to back up your data at the first opportunity and to give the
cooling system a serious cleaning.
Good luck !!!
