Is the motherboard shorted?
My G3 3579 doesn’t turn on nor shows signs of life at all. It doesn’t even turn on the leds when the AC adapter is plugged in.
I don’t know exactly what happened, but my guess is that the motherboard shorted / fried because I opened the laptop to clean the fans, and completely removed several pieces until I realized I forgotten to FIRST unplug the battery.
When I tried to turn it on after I reassembly it, it did turned on but the Dell logo didn’t show up. Fans, keyboard and lights went all on, then turned off again in like 1 sec. I tried several times to turn it on, until it completely stopped to show signs of life and now it is as I first mentioned: not even turns led on when the AC adapter is plugged in.
What tests should I run? What’s your guess, can this be solved?
