ES1-512-C162 dos not start

Hi,

I have the acer ES1-512-C162 of a friend. The issue is that is will not start. If you press the power button the blue light blinks, I hear the HDD start but it stops immediatly.

The BIOS doesn't start.

If I remove the HDD and try to start without HDD I just get a blinking blue light. I also put in another HDD but then ony the blue light blinked.

Can anybody help?
