Should I replaced the Left I/O Board for power issue?
I have a MacBook Pro 15" Core 2 Duo Model A1211 that was dropped. It runs just fine off of a charged battery, but it does not power on without a charged battery installed (does not work off charger alone) and it does not charge the battery when it is plugged in.
Would the root of this problem lie in issues with the Left I/O board? Can you recommend any testing to isolate the source of the problem?
Is this a good question?
