    I had put my KB away some time ago - probably because I had changed the batteries and found it wouldn't work but this afternoon I got it out of the cupboard to use with my iPad and, having found this thread, tried the aluball trick and discovered that it instantly worked - but why?

     

    I took a length of 11.5 mm dia dowel and shaved it down to about 11.1 mm dia so that it would fit tightly into the plastic cup at the base of the battery housing.   I twisted the dowel carefully so that it "unscrewed" the cup from the spring over which it fits and pulled it out.   It comprises a plastic cup about 5.5 mm deep below which is attached an inverted metal cup the base of which forms the battery contact and the open end of which fits over the spring.  

     

    Despite the comments on this moanboard the item is a good simple design - except for one thing.  The plastic cup is about 5.5 mm deep but the +ve terminal on modern batteries is only about 1.5 mm long and the body of the battery does not fit into the cup.  This results in a 4 mm gap between battery terminal and the terminal in the plastic cup.   At some time in the last couple of years battery terminals seem to have got shorter but perhaps nobody told Apple.   It is a shame Apple didn't tell us when it found out.   All the talk on this thread about cleaning dirty contacts will not help bridge this 4 mm airgap.

     

    So, although the aluball trick worked well, I wondered if there was a more sophisticated repair. After spending an hour on the problem I decided there wasn't.   Returning to the aluball, after some experimentation I came to the conclusion that a 6 x 6 cm square of baking foil rolled into a tight ball and packed well down into the plastic cup with a piece of dowel will fit snugly without overflowing the sides and short-circuiting the batteries and it shouldn't fall out the next time the batteries are renewed.  The packing-down can only be done effectively with the cup out of the battery housing.

     

    The filled cup can then be dropped back down into the tube.  It is a loose fit but it slides down controllably back onto the spring by being cushioned by the air below it.

    Hello all,

     

    After 4 years of uninterrupted service, my wireless keyboard suddenly didn't turn on.

    The aluminium ball trick worked perfectly.

     

    For those with a similar problem: take a small piece of aluminium (2cm x 2cm for example, folded over), drop it down the battery barrel, add (charged) batteries and hey presto, the keyboard works again...

    interestingly enough i had the same problem, but found an easy solution. I checked the batteries in my keyboard and they were still making contact... i blew into the battery barrel a couple of times and could smell some residue in there.  Once I put the batteries back in again, it started working... woot!

    I have a aluminum bluetooth keyboard, it was working fine the evening before bed, i wake up the next morning and it doesnt work.  Figured it'd be the batteries so I put in a brand new pair of batteries and the light doesn't turn on.  Really frustrated with this not working.  I've tried a new set of batteries, blowing into the battery case to get rid of any dust, even checked to see if the batteries were snug and they are.

     

    Anyone have any idea's why the light wont turn on, and if there's a way to fix it?

     

    thanks.

    Another keyboard, brought back to life by the ball of aluminium hack! Soo good to see that little green light working again

    If only the blown capacitors on my G5 were as easily fixed

    So I just got a new aluminum wireless keyboard and it doesn't seem to connect. I tried to unplug my iMac for a minute or two and restart all to no avail.

     

    I notice too, when I turn the keyboard on the green light in the upper right hand corner only stays on for a few moments (yet the caps lock light can stay on for several minutes). Is this normal?

     

    Sometimes if I time it "just right" my iMac can "see" the keyboard, but can't connect.

     

    The other thing, I was able to connect to my iPad and it worked great. Could that have anything to do with the issue?

     

    I've put brand new batteries in made sure they are in correct, etc. Still no success.

     

    Help!

     

    Thanks.

    I had the same problem - this morning woke up and the keyboard was dead. Presumed that it needed its batteries changing, since a message had come up about it a few days ago, but despite changing them several times, the keyboard refused to turn on. Following advice on here, I coiled a paperclip around a lollipop stick to get the spiral shape, snipped off the ends (cutting my thumb on the sharp end of the paperclip in the process - be careful!) and then dropped it into the battery hole. Dropped in the batteries after it and voila! Working keyboard!

    Hey All,

     

    Thanks for saving me from teaching my keyboard to fly from my balcony The tin-foil method worked as reported.  Hopefully, Apple will do the right thing and fix this issue.

     

    Cheers !

    Had the same problem and was able to solve it. Just make a small ball of alumnium foil and throw it down the tube before the first battery. Turned on immediatelly. Think the spring must be somehow worned out...

     

    Hope it works ok for you.

    I've been having problems with my keyboard on and off for over a year now,...

    after changing the batteries my keyboard would not work.

    I've discovered.... that my apple keyboard does not like DURACELL batteries

    and the keyboard will only work if the first battery in has a proud tip.

    Try another brand of battery and your keyboard should work.
