I have a G62-465DX here with some very odd power problems. Here's the rundown:
The laptop will not power on from battery alone (tried multiple batteries that are working just fine in other laptops). If the battery is in the laptop and I plug in the power cord the the power light does not light up (the one next to the jack) and it will not start. Now here's where it gets weird... If I remove the battery and then plug in the power cord the light comes on and I can power on the laptop. At this point I can also put the battery back in (light will turn orange and it will charge the battery) Once the laptop is started I can run it off of battery just fine. I can also plug/unplug it while it's on and everything works like it should.
I'd think it was a battery issue if it wasnt for the fact that the battery works fine in other laptops and other laptops' batteries do the same thing in this one. Any ideas what this could be?
