How to Reset the Power Management Unit on a MacBook Pro
I was talking to a tech at Apple this evening, explaining to him that my 1st Gen MacBook Pro has some battery issues. The crazy thing is that it’s one of the recalled batteries, maybe 1 year old. I didn’t think that it would have 1:48 at a full charge. Let’s hope this trick helps.
- Power down
- Remove the battery
- Remove the power cable
- Hold the power button down for 10 seconds
- Plug the power cable back in
- Plug the batter back in
- Condition battery by fully charging and then using it until it is empty
