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)

    Though I felt a bit like a lemming while doing it, I'm happy to report that the tin foil ball trick worked for me as well.

    Hi,

    the transformed paper clip was the solution for me, too. Thanks for sharing the tip!

    RE: NO CONNECTION FROM KEYBOARD TO COMPUTER (after changing the batteries, green light on indicated)

    This has been an ongoing issue for most people and unfortunately it happened to me. I made an appt with the apple "genius" and went to the apple store with my aluminum keyboard and tested it. My keyboard worked. So I went back to work and tried what the apple "genius" told me to do but nothing helped. He actually told me to turn the Bluetooth Off but I forgot that it would be completely impossible because my mouse would lose its connection...the genius should have told me in case you have a wireless mouse then there is another option, but the "genius" didn't. Go figure.

    Apple self help guides you through all the steps to fix technical problems and usually most work, that is if you are patiently reading through all the steps, or not easily frustrated. I did all the necessary steps but again nothing helped.

    I figured the only thing I didn't do was sort of "reboot" the keyboard, by taking out the batteries and start all over again. Sure enough after placing the batteries back in, the computer immediately recognized my keyboard. Again, go figure.


    RE: NO CONNECTION FROM KEYBOARD TO COMPUTER --- DURING LOG IN (after changing the batteries, green light on indicated - solid light for a couple of seconds, blinks twice after)

    NO SOLUTION. Purchase or use an old keyboard that connects to your computer with a USB to log in and type your password then proceed to the necessary troubleshooting.

    Good luck.

    Well my issues wasn't remedied with a piece of tin foil as the power light kept flashing after the battery change.

    But reading Moraesan's response on page 4 or 5 (I forgot which it is) I resolved to turn off the bluetooth devices in my room, then power off the iMac, then power back on. When prompted with the access number I had to type it in twice but it finally worked. I didn't hit the return/enter key, I was just notified that the keyboard was paired in the bluetooth set up menu.

    Sorry but this seems like a common problem that should have been addressed on the trouble shooting section on mac forums every where and the fact that I have been searching so many places threads and found a solution buried on page 4 of a thread where the other solution is to drop a piece of foil to ensure batteries meet the connector is ridiculous. I'd expect this from a PC forum but not Apple. I love Mac so much but this really tarnished my faith in their products. More so than over heating iPhone batteries or video chips in iBook G4s. Don't let my iPad disappoint please!

    Another vote for the magic tinfoil. The keyboard isn't actually mine, but when the user took the batteries out to change them a 'small grey plastic washer' fell out, I'm told. The user just put the washer back in the compartment and then the batteries and then.... nothing. I couldn't get it to work, searched these forums and used the tinfoil trick and off we go. Thanks

    I have the problem with this keyboard.

    PLEASE CALL TO APPLE for the possible change/solution.

    Hardware fabrication problem.

    Thank you !

    My wireless keyboard also would not turn on after a battery change -- I have deployed the little ball of aluminium foil as recommended on this forum and it turned on straight away.

    p.s. Apple -- you may want to ship the foil ball with these keyboards...customer service and all that.

    nice long thread here.... ridiculous problem. similar story -

    "2007" wireless keyboard worked great for 4 months, even after changing batteries. Then all of a sudden out of the blue stopped working. I tried to pair it again and it wouldn't work. It wouldn't find the keyboard initially, then it would see the name after turning it off and on several times. At that point would not pair. Tried another computer... same thing.... over and over.. found the tinfoil trick and that wouldn't work. My keyboard never "blinks" so never seems to go into discoverable mode. Light is only solid or off. Of course I am using fresh batteries.

    Isn't it about time for a recall?

    "I have an Apple Care plan, so I called and was told to shut down. Then remove the power cord from the back of my iMac, wait one minute, plug it back in. Fire up, and then attempt to set up a new device in BT. It worked on the first try. Then to double check, I shut down and restarted and the mouse stayed connect and paired!"

    This worked for me Yeahhhhhhh

    Had same problem of no power after battery replacement. Trouble shot issue to positive terminal in battery cylinder deep inside. Only easy work around was to wind tape on three AAA batteries and put a 1/2 inch screw on negative end and lock the battery cap back on. May have shorter life but for whatever reason the AA batteries are not connecting to the + terminal.
