Hi there!
Your cpu heatsink and ventilation system has definitely covered up with dust!
Your laptop is simply overheated and turns off.
Please try
to open the cover of the laptop and clean the vents in the heat sink
area and the cpu area. It is very likely those vents have been filled up
with dust and down. Remove and clean the heat sink that covers the cpu,
also.
If you find difficult to do that you could let me know the model of the laptop and maybe i could find some instruction on google or youtube on disassembly of the heatsink.
When the CPU overheats then it will shutdown (i.e. thermal overload) and won't boot up again until it has cooled down.If this is the problem 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 withdust the remove the dust and make sure the vents are clear
and dust free. Use acan of compressed air to do this.
Let the car sit undisturbed for 10 - 15 minutes, then try to start it. Check the owners manual if you have it. Sometimes, on various cars letting them sit awhile will allow the system to reset itself. On others sometimes rapidly turning the key from off to on, without turning to start 3 to 8 times within 10 seconds and then on the last turn to the on position leave it there until the horn chirps, at that point turn the key directly to start, or turn off first and turn to start. If all this fails, a dealer can reset the system.
