[QUOTE="Buzzard2010, post: 1187333, member: 176415"] It is designed to do this, for instance if you unplug it and yank the battery out without turning it off it will do the same thing, it's designed like this so you don't lose your data incase of a fault or power failure. Here are the full steps for re-calibrating it... It's a simple procedure. Just plug in the MagSafe power adapter and have the Macbook Pro battery completely charged, till you see a change in the light on the MagSafe connector. The light will change to green and the battery icon on the menu bar of the Macbook Pro will show battery charge is full. Without removing the power adapter, allow this fully charged battery to rest in this full state for the next two hours. Then, disconnect the power adapter, leave the device on till the battery gets drained and it shows the 'battery low' sign. Continue to keep the Macbook Pro on until it goes into sleep mode on its own. Leave the Macbook to be in this sleep state for the next 5 hours. You can check for a pulsing white light on the laptop. When this light stops flickering you know the battery has been completely drained. Once again connect the power adapter and charge the battery completely once again. Once the battery has been thoroughly charged, the calibration procedure is done. Calibration will minimize the number of Macbook Pro battery life problems in the future. Hope this helps - Simon [/QUOTE]
