ACER laptop unbootable

hello,
past few days my laptop freezes without heat roughly 45/50 °. Then I had the problems started in the average temperature . When applied power button, the LED indicating that the laptop is on is ok (so it seems that the food is ok?). The CPU fan runs for 2 seconds and stop again .
I await your opinion on the matter.
Thank you in advance to all those who give me an answer.

Hello,

Try this: Hold the button walk for a few seconds without power supply and battery.

Can you replace the battery ?

Dr. V, thank you for your reply.
So I tried but without success. The pc still does not start

how many years old is your laptop ?

Hello,

Maybe the hard disk that a little HUMOR!
Try to get a CD of Windows to boot from the Recovery Console.
