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)

My wireless keyboard wouldn't turn on after I changed batteries. I tried the foil ball and other recommendations. Nothing worked. I thought something had failed or disconnected inside. I flipped it over to look for access to the back and noticed a faint graphic on the exterior of the battery tube.

I had put the batteries in 6 times and didn't pay attention to they way they came out. I reversed them and we're back in business. Green light is on.

I know my way around a spludger, I've changed hard drives, fans & memory in multiple MacBooks and missed the most obvious solution.

If you've given up on your wireless keyboard, give this a try.

Had the same exact problem - the tin foil solution worked for me.

I used a small staple, folded into a square shape, and it worked!

Foil worked for me. Have the first version of the bluetooth keyboard and was frustrated that the $70 keyboard was busted. Thank you for submitting this fix!!!
