Left CTRL key stopped working on HP ProBook 450 G2
My laptop runs on Linux and Windows 10 and on both systems the CTRL key did
not work properly.
BIOS was the problem.
If your CTRL key does not work, first check if you can use FN key
instead of CTRL.
For example, FN+C is the same as CTRL+C or FN+V is the same as CTRL+V.
You can try this with a line from a text.
If the FN key works as CTRL key then
turn off your laptop,
unplug it,
TAKE OUT THE BATTERY for 10-15 seconds and then put it back in and turn
the laptop on.
The CTRL key should work normally now.
