Did you install some keyboard mapper / keyboard mapping program?
To check: boot into Safe Mode.
If still wrong, boot into some Linux disc or stick (free to make) and try there.
Only if it's still wrong in Linux, it's a hardware issue.
Hello! I noticed yesterday that my "t" key doesn't work any more. It doesn't work on either my laptop keyboard, external keyboard or the on-screen keyboard. HOWEVER, i does work if used together with "shift" as a capital letter "T".
I've read around for solutions for 2 days now but can't find anything helpful.
I've already tried to:
Power off, unplug all wires and hold the power button for about a minute.
Clean out the keyboard.
Uninstall HID keyboard device drivers and reboot.
Any idea on what this can be?
