Charger LED is dim, will not power on.
I was given a Macbook Pro that will not power on. The green LED on the Magsafe charger is very dim when plugged in. I have cleaned the contacts and opened up the charging block. When plugged in the charger is putting out 16.3 volts. I assume it is working. Would a bad DC in board cause this issue, or might it be something else?
