My girlfriends Macbook Pro battery was drained completely. Upon awakening from charging a little, the screen displayed the last webpage she visited only it was in black and white until she pressed the spacebar making it color again. She closed that window and tried to restart, it seemed frozen so she held the power button down. Power up thereafter was painfully slow, several minutes on Apple logo w/spinning wheel then several more minutes on wallpaper and even longer loading dock along with desktop items. I'd say it takes 15-20 minutes from power button to completed desktop. All other programs run very slow also. All I've done was remove battery and hold power button to no avail. Any insight into our dilemna will be greatly appreciated!
