Hello snair,

 

I understand that your laptop will not power on.

 

Have you checked that ac adapter?

 

Do a hard reset.
Turn the computer off.
Remove the power cable and the battery.
Hold down the power button for 15 sec while booth power sources are removed.

This should reset the hardware in the computer.

Hello anthony82,

 

I am having the similar problem with my Compaq Presario CQ40. I have already performed the hard reset but the same problem still occurs, it would restart after turning off though..but after 3 seconds it would turn off again.

 

Could it be a hardware failure?

Looking forward for your reply, thanks!
