I have a 2007 Macbook Pro and for nearly two years, the battery has been toast. In April, Apple replaced the logic board. Since the repair, whenever the power cable comes loose, the MBP shuts off as expected.
Before the repair, when the power cable was unplugged, the MBP simply shut off. Now, when I plug it back in and turn it on, it boots back up in the previous state, but has a white screen with loading bars at the bottom.
I haven't found anything related to this on the web. Is this related to the new logic board, or is there something else I should be concerned about? The MBP is running Leopard and is up to date.
