El capitan 10.11 keyboard crazy after sleep

Hi Peps,

I have the same thing going on, exactly as you described. I have a Mid-2015, 27" Retina 5k iMac, US Wireless Keyboard (2011), Magic Trackpad and Magic Mouse on 10.11.1. So far, I have worked with Apple support and had the keyboard replaced. This did not fix the issue. I need to call them back when I have some more time.

I wanted to ask you a few questions to see if our issues are exactly the same. If they are, I'll be happy to share any solutions I come across.

If your sound is up, can you hear a noise as if you have held down a button for a few seconds?

The caps lock key does not respond (light indicator) while this is happening. Can you confirm the same?

Does your battery life say 100% on the keyboard all the time?

Previously this has only ever happened coming out of sleep and on the lock screen. Then, yesterday for the first time, I saw the same behavior while pasting an address to the address bar in Safari. It just pasted over and over again. I could tap delete and it may back up, but then it would go back to pasting. It acted the same as it does sometimes at the lock screen. I had to to turn off the keyboard and turn it back on, then as usual, everything was fine again.

All the best,

John

Hi Peps,

I will have to check with the other keys that you mentioned. The sound that I was referring to happens during the "automatic typing" problem. Normally, if you type in the wrong password and then press enter, you get that sound (complete with screen shake). When the password field automatically fills itself in after waking, it makes this same sound, but as if someone pressed enter several times.

The problem hasn't happened again in over 3 days. This is about as long as it has gone without having the issue. I noticed that you and I both have a bluetooth keyboard, mouse and trackpad. I don't know if you have all of them on or not. I decided to turn off the trackpad and only have the keyboard and mouse on, then I switched to just the keyboard and trackpad. After that, I decided to leave them all on again. I don't know if it is just a coincidence, but since I turned off the trackpad and turned it back on, the keyboard hasn't gone crazy again.

All the best,

John

... and there it goes again. I'm going to turn off the trackpad and leave it off for a while to confirm it isn't related.

I did not get a flashing caps lock upon clicking cancel, but I did see the lag when pressing the volume controls.

No issues for about a week. I'll turn the trackpad back on now and see what happens.

Hi Peps,

I went from my Nov 9th post until just now with no issues, and I think I've finally narrowed it down.

Details, details... my keyboard and iMac are one shelf above whatever pointing device I am using. That means if both my trackpad and mouse are on, the one I'm NOT using sits next to my keyboard and almost under my iMac. The pointing device that I AM using is just below on a sliding drawer.

Results:

With my apple bluetooth keyboard and magic mouse only, no problems.

With my apple bluetooth keyboard and magic trackpad only, no problems.

With my apple bluetooth keyboard and both pointing devices on, using the magic trackpad (on lower surface), no problems.

With my apple bluetooth keyboard and both pointing devices on, using the magic mouse (on lower surface), FAIL - trackpad is next to keyboard

Do you have the trackpad on and close to the keyboard and iMac?

Can you use just the mouse and tell me if you have any issues?

If not, can you get the trackpad further from the keyboard and iMac to see if you still have an issue?

I may have not noticed something, but I'll pay close attention to see if there is only 1 configuration that gives me trouble.

All the best,

John

It did it again... so this time, i didn't turn off the keyboard. I turned off the trackpad... guess what? the the keyboard stopped typing by itself. I am now convinced that the trackpad being off will cause this to never happen... at least in my case.

I have exactly the same problem, every time after iMac's sleep.

Only switching of and on again the bluethooth keyboard helps.

Issue startet with update of OS.

Thanks for the help, Peps! I'll send this to the tech who replaced my keyboard.

All the best,

John

Reported to Apple support on phone. Information will be provided to the senior advisor who I first spoke to. The person I just spoke with restated our exact issue to me and I am confident that she understood the problem. I'll let you know if i hear anything else.
