how to restore factory defaults if my computer won't turn on?

[Shelly kay]

I cannot get my laptop to stay on. When its unplugged the power light indicator will light up for 1 second then turn off again. When I plug in the charger, the laptop starts going crazy and automatically turns on and off over and over again and it won't stop until it is disconnected from the power source.
At first the computer would turn on but the screen would stay blank but I figured out how to get it started but now I can't get it to do anything. Please help!!

Restoring to factory defaults (commonly called Factory Recovery) is not possible while the laptop keeps turning off & on, and in any case Factory Recovery won't fix that problem because it's hardware-related.

The laptop needs taking to a PC/laptop repair shop for diagnosis of the problem, but ask for an estimate of repair cost before giving them the green light to repair it.
