I plugged USB keyboard and could then use macbook until I shut it down. Just tried hard reset and it came back on, however I have noticed keyboard doesnt seem to be working but lights are on in background (Trackpad works). Yes it did charge battery fully and all light indicators are now green, lights went from green to amber. Lights with the other battery - bad original battery. This would be for a 'no start' scenario but basically it's the SMC reset w/ a battery you can remove. The addendum to this would be to try a known good battery. No? - Go through the same procedure and try to start without the battery connected. Let the computer sit for 5 minutes, Reconnect and try to start up. Use your fingernails.) and power adapter. Disconnect the battery (open the bottom and pull the connector off.

No lights in either case - possible bad DC in board. ' Tried another battery from another mac book and it comes back on!'ĭoes the charge light come on with the other battery? Any lights on the MacSafe plug? Green or amber (charging).
