How do I know if the logic board is bad?
So here is what is happening:
- if I plug it into my PB it does not respond, nor does it start to charge
- if I do a "restart" (menu + center button) with it unplugged I get the exclamation point with the battery (low battery indicator)
- if I do a "restart" while it is plugged into the laptop, I get the lightning bolt with a battery (battery is too low to be recognized by computer)
- if I plug it into the regular AC charger, I get the same results
- if I try to "restart" again, the screen goes blank and then the lightening bolt comes back eventually
I opened it up again and took a volt meter and measured that the battery is still good; I get 3.8V I think or something like that from the red and black wires of the battery. Plus this thing is only like 8 months old, so I know the battery isn't bad.
This leads me to believe that the logic board is bad b/c that is what the battery plugs into. The screen must still be ok b/c it looks fine.
So does anybody have any ideas?
