Laptop turns on and off repeatedly.



Problem description:The laptop turn on without showing any image on the screen. After a few seconds the laptop turns off by itself. Then it turns on and off again. It continue turning on and off repeatedly until you power off the laptop completely.
Possible problem:
Most likely it happens because of some kind of motherboard failure. You can try reseating/replacing memory as I described in the Problem 2. If it doesn’t help, I would say this is motherboard related failure.
In most cases it’s not worth replacing the motherboard, better to buy a new laptop.
