I've also got battery drainage problems with my Wireless Keyboard. I've got firmware version 0x50. I have done all the Software Updates up to date... and this problem keeps coming back. I've also got a Magic Mouse and that one also drains batteries rather quickly however slower compared to the keyboard.
Keyboard can drain a set of batteries per week quite easily. The mouse is more like once a month.
My wife has a Mighty Mouse + Wireless Keyboard and it doesn't present the same problems... hers is a Macbook Black which is different than mine, not sure if this has anything to do with it though.
I think I will log a case with Apple Care and see what they tell me. Will keep you posted.
My 2007 Aluminum Bluetooth Wireless Keyboard (-numeric pad)... is eating batteries also.
I have to unscrew the battery cover whenever I am not using it in order to conserve battery life.
Otherwise I can only get maximum about 3 hours!!!
any suggestions or is the alternative another BT Update from APPLe ??? when when when?
I was having the same issues with the wireless keyboard that came with the 21.5 inch iMac I purchased in December. I also have the magic mouse and track pad. I took it back to the Apple store, (who naturally said I was the first person to mention it), and they swapped it for me. When I first set up the replacement one a seven digit number was dispayed on the screen which I had to enter on the keyboard. This didn't happen with the orignal one. It has now been about three weeks and all of the devices are still showing 100% battey charge.
So it looks like there was a problem they may have fixed.
Ah, this is a rather disappointing thing to discover! I just bought my iMac in December, just barely more than a month ago, and haven't had much chance to use it since then, but today I turn it on to find a warning that my keyboard batteries are down to 17%!
Have there been any updates from Apple about this since the last post? Any comments that would indicate that they are working on a fix for this problem? If not using the Magic Mouse will solve the problem, I've got plenty of spares to use instead.
I've experienced this problem too.
I mentioned it previously in the forum - http://discussions.apple.com/thread.jspa?threadID=2588388 - but it seems to have been classified as 'answered', even though the problem quite clearly still exists.
I've reported the problem to Apple, as suggested in the aforementioned forum entry. I suggest you do the same.
Well, my one lasted almost half a year, my battery status now is 3%
Snow Leopard would not effect the keyboard, I am very sure.
It is probably because your keyboard is a bit old, a some strange problem happened
Trying putting Energizer ADVANCED batteries instead of rechargeable or Energizer MAX ones, since Advanced lasts longed
The only try is to put good batteries, if it still 'eats' it would be the keyboard's problem, and you can't fix it.
I just hope I don't get my keyboard like yours...
I too have a 22" Mac OSX Snow Leopard purchased just 4 weeks ago, and have had to replace batteries twice already. I switch the keyboard off ever time I have used it, but makes no difference. I think I will have to use the ordinary plug in keyboard, can't keep up with replacing batteries at this level. If you find an answer to this problem please let me know. Seems after reading the posts on this forum that there is no cure for this problem. Very disappointed in Apple for not solving this issue.
I reported the battery problem to the Apple shop where I bought my computer, I am having one to one lessons there. They eventually agreed to change my keyboard. I was told that the magic mouse wakens up the keyboard but they said they had never heard of the mouse affecting the keyboard. I insisted that it did and to prove it I have only used an ordinary plug-in mouse for the last 3 weeks. The battery life on the keyboard is still 100% and so is the mouse. I also tried another experiment, I used the magic mouse only and an ordinary microsoft keyboard, leaving the Apple keyboard alone for a week. Well, the batteries in the keyboard had gone down to 16% even though I had not used it. So that to me proves that using the mouse drains the life out of the keyboard. So for now, I do not use the magic mouse, just the plug-in mouse with the Apple keyboard. Charging the batteries in a battery charger is also a waste of time as they only re-charge to approx. 50% of their life, thus lasting about 1 week at the most. So my advice to everyone is to use a plug-in mouse as the magic mouse is not very magic!
Try doing following:
Open Bluetooth in System preferences.
Disconnect your keyboard and then remove it from the list.
Then pair your keyboard again.
It seem to do the trick for me (my battery lasted for a week now and its still above 50%). Before it lasted for 3 days max.
One more tip: whenever you're not using your computer, turn off magic mouse.
