Apple bluetooth keyboard awakes from sleep with a unentered character string. Why

I have a 18 month old MacBook Pro with and I7 processor, 1 TB of memory, 16 GB of ram, and the Retina display. I am running OS X 10.11.

When my year old Apple bluetooth keyboard awakes from sleep, and I enter a login password, the entry has many more characters than I enter. Sometimes it appears to enter an alternate character set, literally greek, I think. If I use the MacBook's native keyboard everything is fine. After I cycle the power on the bluetooth keyboard and cycle the bluetooth, it is fine until I leave the MacBook unattended in my office and the machine sleeps, then the keyboard awakes and often but not always does not seem to work without cycling power and turning the bluetooth off and on again.

I currently have a jambox, keyboard, trackpad, and magic mouse attached to bluetooth. Everything was working well until I upgraded to El Capitan a month ago. Coincidence?

I welcome suggestions on a more elegant fix than cycling the power. Or is it time for a new keyboard.

Hi, bbkarr.

Thank you for visiting Apple Support Communities.

I understand that your Apple keyboard isn't functioning as expected after waking from sleep. Here are some troubleshooting steps that I would start with for this issue.

Resetting the System Management Controller (SMC) on your Mac

How to Reset NVRAM on your Mac

If your Apple wireless mouse, keyboard, or trackpad aren't working as expected

Cheers

Hi,

did you ever solve your problem?

I think I have the same issue, but no solution.

The SMC / NVRAM etc points did not help me, neither to reconnect the bluetooth devices.

Maybe you can help me further how to fix the keyboard.

Thank you!

I still have this problem. Did you ever find a fix. I have tried new batteries? Wondering if it is interference with cell phone or wireless landline which is in my office. Generally I turn off the BT keyboard, turn off BT on the MAC and cycle power on the MAC. It clears the immediate problem but the problem still returns. If you have found an answer let me know.

Thanks and sorry I can't be more helpful. Wondering if Genius bar could help.
