Question The left control function keys (cut/paste/undo) wont work on my EliteBook 840 G3

Try the following...

  1. Uninstall the keyboard driver.
  2. Reboot the computer (without reinstalling the driver).
  3. When it restarts, it should reinstall the driver on its own.
If this doesn't work, you may wish to try connecting/reconnecting an external keyboard and see if it works fine. If it does, then it could be the keys themselves that are the issue.

Additionally, if your device uses one, you may want to try updating the Synaptics Driver if the above doesn't help.

You may also want to check the device for malware, viruses, etc., which can interfere with normal operation.
