Hardware :: Apple Wireless Keyboard Randomly Stops Working?

My Apple Wireless Keyboard is haunted. It will randomly, in the middle of sentences, or sometimes after I haven't used in a few minutes, stop responding.

The really weird part? I open System Prefs, click Bluetooth, and viola! It works again. I don't have to do anything - just open the Bluetooth prefs. As soon as I do, everything I've typed since it went dead (usually just a word or two) is actually output into the search box in Systems Prefs.

There is no rhyme or reason to this weirdness. Sometimes it will literally happen a few times an hour for days (which drives me up the wall); sometimes it'll go months without doing it. When it's doing it a lot, no amount of rebooting/relogging-in fixes it. One thing I have not tried is using a fresh user account (or Guest), because it's so unpredictable... even on my own account it will take a break and work normally for a few hours, then go right back to freaking out.

The fact that it stores everything I type when it's "not working" is the really weird part. It's like the OS is receiving the data but just forgetting to process it until I poke it and remind it, "you have stuff coming in via Bluetooth, wake up and do something with it!"
