My wireless keyboard (2 battery type) has suddenly started eating batteries. Previously I could go for weeks or even months before having to change batteries. Recently I'm having to swap batteries daily. Even multiple times a day!
I use rechargeable batteries, and I assumed the batteries must have outlived their natural lifespan, but I just bought some new ones, and they're fully charged, but when I put them in the keyboard, it shows only 30% battery life remaining!
Is they keyboard past its pull date...?
Try the following in order as necessary:
1 - Reset NVRAM or PRAM on your Mac - Apple Support
2 - How to reset the SMC of your Mac - Apple Support
3 - boot into Safe Mode by booting with the Shift key held down. Reboot normally and test.
NOTE: Safe Mode boot can take up to 10 minutes as it's doing the following;
• Verifies your startup disk and attempts to repair directory issues, if needed
• Loads only required kernel extensions (prevents 3rd party kernel/extensions from loading)
• Prevents Startup Items and Login Items from opening automatically
• Disables user-installed fonts
• Deletes font caches, kernel cache, and other system cache files
Thank you for your reply, Old Toad!
I've tried #1 above, and discovered that it's not simply a matter of my keyboard eating batteries. Now my computer is also not recognizing my keyboard every time I reboot... which makes resetting a bit of a challenge! However, I did ultimately manage to reset PRAM. That doesn't appear to have helped the issue, as my computer still didn't recognize that I had a keyboard afterwards!
I'll continue trying the other suggestions....
Progress! After resetting SMC, my computer at least now recognized that I have a keyboard after rebooting! Hooray!
I don't know yet if the keyboard is still eating batteries like they're going out of style--fingers crossed!
I very much appreciate your taking the time to help, Old Toad!
The keyboard may be at its end of life. Do you have another Mac you can test it with?
