Answer to: How do you Solve Service Battery WarningThere is only two ways to fix this: SMC - Static discharge 1. Take out the battery and disconnect MagSafe cord 2. Hold the power button for 30 seconds (static discharge) 3. Plug-in power adapter & MagSafe cord, wait until the cord LED is green 4. Put the battery back in If that doesn't work ... 'Recalibrate the battery (takes a long time) 1. Charge your battery up to 100% until the MagSafe cord LED is green 2. Disconnect the MagSafe cord and run the system all the way out of batteries 3. Put the computer to sleep (5 hours) to finish discharging the batteries charge 4.
