I've got a wireless apple keyboard, about 6 months old and it is killing batteries. I use it for my HTPC with a mac mini, so it get used no more than a couple hours a day of actually being connected to an "awake" mac mini. The mac is asleep when not in use (90% of the day) and the batteries are quality batteries. I've tried PowerEx and now using brand new Eneloops. The firmware on the keyboard has been completed and is up to date. Batteries die after about 7-10 days. Any ideas?
