I use my 13" MBP connected to an external display with a magic mouse, magic trackpad, and apple wireless keyboard. I always used to wake the laptop from sleep by pressing a key or clicking, but recently this has stopped working - the only way I can wake the computer is by opening the lid, but the bluetooth accessories still connect and work fine. This means I can no longer use only the external display, say when I want to watch videos. I have tried unpairing and repairing all of them, as well as restarting, doing a PRAM reset, and restoring my computer to a time machine backup of when they were working, all with no effect. Any ideas? Thanks.
