Wireless keyboard stopped working, flashing green light (not batt. related)

My wireless keyboard has not given me a single problem until today. When I turned my computer (intel iMac) on this morning I also turned on the keyboard as I usually do. Rather than the steady green light I usually get, I now have a flashing green light that eventually turns off after a minute or so. I've changed the batteries to brand new batteries. I've even tried using new packs of different brands of batteries. Nothing works.

The computer no longer sees the keyboard.

Any ideas as to what the problem is?

Hi, I started having trouble today. My white Apple bluetooth keyboard will now not work or pair with my computer. I get a flashing green light when I turn the keyboard on but the computer will not put in the list when you choose keyboards in bluetooth setup assistant. It will however show it if you choose all devices instead. I can't pair it from there however. This happened overnight, didn't install anything or even turn my computer off and it didn't sleep. not sure what to do now, tried what's been suggested here, except buying a new one which I'm not keen on doing as the new wireless keyboards have no number pad.

I think when the new aluminium Apple Wireless Keyboard batteries die, it corrupts the Bluetooth preference file. My batteries ran out, I changed them, but could not pair – the pairing pass key dialogue did not even come up!

BUT the keyboard worked at login, when I had to input my password, but once my user desktop appeared, it stopped working. I assume the root level OS (ie before user loging) uses a different preference file of something.

I deleted the bluetooth plist thing, restarted, fixed permissions, etc, and it worked!
How I discovered this, was that I noticed that I could not access the Bluetooth preference file, in the Bluetooth pulldown menu – I got the spinning rainbow disk!

Apple needs to get this sorted. The bluetooth preference file need to be robust enough to deal with a run down battery.

PS Tried the Airport interference thing, but that had not effect!

HI
Same thing for me. New batteries lasted 2 weeks?!
Well I fixed the blinking/unpaired problem by deleting the keyboard name in the bluetooth pref panel.
(This can be done without the keyboard- use your mouse to highlight the name and edit menu to cut/delete. Close pref. Re-pair.)

This is just one way. Logout or restart are always a good first bet, deleting the pref.list file could work too.

Hope this helps.
