m5884 powerbook 4g does not turn on. The battery charges. The connector light is green. It just does not want to power on. I've changed adapters. Did what you did on the video about the PRAM.
I push the power button and nothing happens. The battery is fully charged. I even tried to power on with and without the battery. I've left it unplugged with nothing for weeks at a time.
It was working fine. I put it away for a few month. I was overseas. When I got back, I plugged it in and that's when it didn't turn on.
Hope you can help me. Thanks!
