iMac keeps searchong for bluetooth keyboard?

by dklosen / November 29, 2012 11:46 PM PST

Hello...I have a 27" iMac bought in 2011. I am using an apple usb keyboard. Sometimes when I start or restart, a dialog pops up that says something about no keyboard attached and the computer is searching for a bluetooth keyboard. The usb keyboard is definitely attached but does not work unless I pull the usb out and plug it back in. This hasn't happened since apple replaced the motherboard 3 or 4 weeks ago. Prior to that, my motherboard had issues that required apple to replace it. My motherboard issues were causing the computer to not display properly, but during that time, I started getting this same bluetooth keyboard search issue. Is it possible that my motherboard is again crapping out after 3 weeks? If not, any suggestions on what to check regarding this? Should I trash any bluetooth prefs, etc?

Yes, of course it is possible that the logic board is going

the same way as the last one but the first thing I would try is to turn OFF Bluetooth.

That way, the system will not bother searching for one.

I would also consider replacing the keyboard with another USB one to see if you have the same, "Doesn't work until I unplug it", problem

If neither of those two things work, then it's back to Apple to get them to take a look at it

iMac overriding plug in keyboard with blue tooth
by effect63 / June 29, 2014 10:30 AM PDT

I'm having the same problem, plug in keyboard is totally dead and blue tooth search begins, have to restart the mac sometimes up to 3 times to get it to recognise there is a key board already plugged in. I have tried to turn the blue tooth off and it just resets itself to on again after the computer reboots.

iMac keeps searching for a bluetooth keyboard

I just turned mine off, unplugged the power cord and held the power button in for 10 seconds. Then I plugged it back in and turned it on. Wired keyboard is working now and it's not searching for the mysterious bluetooth keyboard.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
