Lately when I have been using my Apple Wireless Aluminium Keyboard with my iPad, I have been noticing issues such as it typing two of the same letter, or lagging at plugging in the letters. It was really bad before I restarted the iPad, not sure that resetting it would help since people with Macs have issues with this aswell, found in these communities. I don't think I could get a firmware update for it on iPad, I'm having to type this discussion through Splashtop on my iPad since I can't enter text in this field with my iPad (probably because I'm using Atomic Web Browser), and the keyboard hasn't lagged.
Is there a way to fix this? For example, when I was typing the title on my iPad, it said AApple Wireless Keyboardd Lag, and many more variations of this.
This could be something as simple as the batteries going bad and in need of being replaced. If you are seeing the same problem with the keyboard when you connect it to your Mac and you have replaced the batteries, then the keyboard may be going bad an slowly dying for good.Hope this helps.
