Acer 5742ZG power issues

[Learn2Day]

Hi everyone,

This laptop doesn't turn on, but as soon as i connect charger or press power on battery, the DVD drive turns on.
I've checked for burned or over heating components, moist, but I see nothing.
I'm stumped where to check for faulty components.. Can you help?

Thanks.

What graphic card is in there? Is it onboard or a separate card?
Can you remove the DVD drive and tell me if you hear kind of a clicking sound when powering it on?

ATI onboard. no sounds.
Also might be worth mentioning i replaced RAM and CPU with no results.

Thanks.

Might need to flash its bios.

I doubt it's related to BIOS. The fact that the DVD powers up as soon as I plug the charger (without pressing power button) makes me believe the issue is in the power module.
Problem is I'm too much inexperienced to check it without help.

Often experience this, mostly related to bios or bios battery.
