so how could i test that?
could it be my hard drive? i really doubt that though.
 


Yes it will be a wise choice, because troubleshooting the motherboard, you need experience and the knowledge of how the laptop is powering up. The best way to resolve your problem, if you don't want to go to a store for the repair, is to buy a new motherboard, it's cheaper than the repair.
