Ctrl shortcuts partially working

[chule92]

Some shortcuts on my laptop keyboard are working normally while pressing keys simultaneously (Ctrl + A, Ctrl + S, Ctrl + N, Ctrl + D...), but some are not (Ctrl + Z, Ctrl + Y, Ctrl + X, Ctrl + C, Ctrl + V...).

Actually, they are working only when I: press and hold Ctrl + C (for example) and then release only Ctrl key, but when I simultaneously press the key combination like it suppose to, nothing happens.

I tried uninstalling the keyboard driver from device manager, no luck.

Recently, I had a problem with my laptop keyboard (some keys malfunctioned) which I solved by holding on/off button while laptop was turned off, unplugged and without battery. Maybe this strange issue is connected with this?

When you uninstalled the keyboard driver, did you make sure to reboot the laptop before having it reinstalled?

If you did, and going by the other problem you mentioned, I would start to wonder if there are any damaged/loose connections to the keyboard.
