Wireless keyboard won't turn on after changing battery

Thank you so much...I did what you suggested and it works, a thousand thank yous!

Same problem. Use screw driver to 'scratch' (clean) the contact. Also check the battery contacts. After a few attempts, it works.

13 August Same problem, installed new batteries and no keyboard light.

Followed suggestions to scrape the contacts at both ends of battery compartment

and lightly on battery terminals. May take a couple of tries but it works.

Like so many others, same issue. My solution is slightly different.

I cleaned contacts. No change.

Tried aluminum foil ball, which I've seen elsewhere. No fix.

Finally, tried loose ball of Steel Wool. Voila! Solved.

Worked fine! Thanks.

I had the same problem. I didn't realize that on the right side of the keyboard, directly opposite the battery compartment, is a power switch.

What an awesomely simple solution. Hats off to you friend, brilliant! Had me thinking the keyboard had expired cos this has happened in the past and I changed the keyboard. Thank you so much.

Make sure batteries are in correctly, directions are on the bottom of keyboard. Also, simple but I forgot the "on-off" button on the other side from batteries. Simple but I missed it at first.

Just wanted to say that I also had the same problem as everyone else. Even tried to clean the positive contact as discussed in other threads. No luck with that option however the aluminum foil trick worked immediately! Brilliant!! Thanks very much!

Of course you all know you have to press the button on the right side of the keyboard after you replace batteries? I have had multiple battery life problems with my Magic Mouse and my Bluetooth keypad since upgrading to El Capitan 10.11.4. It's a software issue. New batteries don't always fix the lack of connection. Although my device appears on the Bluetooth page, it says not connected. I have spent too much money using non-rechargeable Duracell batteries in my wireless devices manufactured by Apple since upgrading to El Capitan. Get some rechargeable batteries at Best Buy (I don't work for them.) and keep replacing batteries until Apple figures out why El Capitan is draining our Bluetooth devices battery life. Duracell says it's a storage issue, but these were brand new from the store and the package, yet they sometimes only last 24 hours. It's El Capitan. I'm convin

Is is a possibility that because we're using rechargeable batteries, that the constant inserting of the batteries into the charger is wearing away the metal contacts? This would explain to my mind why the insertion of something metal into the area alleviates the problem.

You asked a question of the original poster that is eight years old. Obviously he is not going to respond. Drop the "hope this helps" trolling, please
