I have had a couple of weird Macbook issues with my Macbook in the last week. First it didn't go to sleep properly and the fans were going on full, I had to remove the battery and restart it. Then this morning my Macbook didn't go to sleep properly and when I got to Uni it was warm, I opened it up and the backlight was off but the screen still on, the backlight wasn't switchable on with the backlight keys, though the mouse seemed to be beachballing, again to use it I had to remove the battery, it now appears to be working correctly. All the threads on this have been archived. What is going wrong? Normally it is usable on my knee so doesn't seem to have a heat problem. Do I need to take it into an Apple Store?
