Q: Wireless keyboard won't turn on after changing battery

This is what happened:

I got a message yesterday telling me that the battery for my wireless keyboard was low and I should replace them. This morning, before I switched on my Mac, I put in new battery for the wireless keyboard. Then I switched on my Mac. And I got a message on the screen saying that There's no keyboard connected and couldn't find any keyboards. I thought that maybe I need to turn on the keyboard to make it work. So I pressed the power button and noticed that the green light doesn't even come up..

What's going on? Is my wireless keyboard already dead??

Any advice would be appreciate it. Thanks.

G5, Mac OS X (10.5.2)

    Tinfoil 1 : Apple 0

    Can't believe that a small piece of tinfoil solve my wireless keyboard problem. Maybe ms can use this for their next advert

    My keyboard has no problem connecting the batteries although I did the tinfoil trick just in case.

    My keyboard will show the green light for like a second then it disappears which I assume means that the keyboard turns off and doesn't give the computer a chance to connect to it.

    Is there any fix for this? It just started last week I believe. I rarely even use this mac so as far as the keyboard being used and abused that is not the case at all as it normally just sits here doing nothing.

    Tinfoil for the win!

    Fixed it for me too. Wondering if I should bother trying to get a replacement keyboard or just deal with this one.

    Hi,

    I have the same problem; reinserted the little gray cap and can't get it out. Aluminum wireless keyboard won't power up. No green light. Nothing.

    Did you find a solution? Does the foil work if you've already reinserted the gray cap? I'd like to know before I stick anything else down there.

    Also, can the small plastic shield covering one of the batteries in the battery compartment be removed or is it permanent?

    Thanks!
    Joan

    I had this issue happen a couple months ago. I balled up some solder, dropped it in and it worked. I went to change my batteries yesterday, and the ball came out with the batteries - and now I can't get it working again.

    Has there been any official word on getting this fix? I'm out of warranty and don't want to pay $80 for a new wireless keyboard with battery compartment issues.

    I used a small portion of a paper clip on the contacts inside and it started to work again. Thanks for the suggestion. But what kind of product is that Apple? I mean, I loved Apple products but these small stuffs makes you literally scratch your head.

    Please do something about it.

    Many thanks for the aluminum foil solution-worked immediately. Sad, sad, sad that one has to have to find their own solutions such as this. My keyboard is two months out of warranty. As an addendum, my wireless mouse has become useless as well after 14 months. Scroll works only intermittently despite cleaning as recommended and scroll ball no longer able to bring up dashboard by pressing it. Lousy quality control.

    This is ridiculous! My keyboard stop working and I just found this discussion thread. It seems a lot of people have the same problem for this past 2 years!
    I've tried the foil ball tip twice and finally got it to work.
    Basically the size and the location of the ball probably matters too. It can't be too small, can't be too big either.
    But I just feel NOT happy about the fact we need to use a tip like this to solve the issue. Apple you should do something!!

    I also must say thanks for the aluminum foil tip. After changing the batteries in my keyboard it refused to switch on. But after using the aluminium foil it now works fine.

    Same issue here, iMac from Summer 2008, keyboard dead after battery change.

    Tinfoil: fixed it!
    Thanks again for the suggestion.

    I thought you all were crazy, but I had nothing to lose.
    I had already tried 3 sets of batteries and even followed a different thread which had me sand the bottom + contact with a dremel tool, all to no avail.
    So I decided to try the "foil theory" if nothing else for the amusement factor.
    Well, I am writing this from my wireless keyboard! I cannot believe this worked!
    Good post you guys.

    Same here. Kudos to the foil solution. My wireless keyboard is now working again (after a good deal of battery changing frustration), thanks to a little ball of tinfoil. Apple should put this solution on their website. Thanks to all of you for sharing!
