I use an external monitor with my MacBook,, Bluetooth keyboard won’t wake it any more.

I have woken my MacBook by tapping on the shift key for over a year now, and a few days ago that stopped working.


Now I have to take it out of the cabinet where I keep it, open the lid, press the power key and then I can close the lid and put it back in the cabinet.


A bit over a week ago it wouldn’t recognize my Bluetooth mouse, (which I’ve also been using for over a year) until I got another mouse, paired that one with the computer, and then went to system preferences and removed the non working mouse, paired it again and now it’s working.


Is this a hardware issue?!?

Why do I have difficulty with Wi-Fi or Bluetooth devices when USB 3 devices are attached to my computer?

Some USB 3 devices can generate radio frequency interference that can cause Wi-Fi and Bluetooth devices operating in the 2.4GHz band to have issues communicating with your computer. Here are some tips to avoid this issue:


  • If your USB device has a cable long enough that you can move the device, place it away from your Mac—and make sure not to place it behind your Mac, or near the hinge of its display. The antennas for Wi-Fi and Bluetooth are located there, and USB 3 devices placed there might interfere with your wireless connections.


  • If you're using adapters or dongles on a Mac computer with Thunderbolt 3 (USB-C) ports, plug them into the front port on the left side of your Mac, or into the ports on the right side (if your computer has them). These ports are the farthest away from the antennas, making interference less likely.


  • To avoid interference on the 2.4GHz band using Wi-Fi, try using the 5GHz band instead. You can change this on your wireless base station. Bluetooth always uses 2.4GHz, so this alternative isn't available for Bluetooth.
