Lenovo ThinkBook 14s Shutdown backspace key
Lenovo ThinkBook shuts down when backspace key is pressed.
This problem happened after a couple of months using the laptop. Tried using a USB keyboard and this problem didn't occur and backspace on the USB keyboard works as expected.
SOLUTION:
Microsoft Windows is updated to the latest release and Lenovo ThinkBook 14s BIOS updated to the latest version.
