Ответ на "Keyboard doesn't respond after pressing Caps Lock."My computer is Thinkpad X220t. However, I have the same problem: when the Caps Lock key is off, everything works fine. When the Caps Lock is on and the led is lit, the system starts behaving erratically. Some windows freeze, other keys render wrong characters (ex euro E), etc. I'm using Ubuntu Linux. I suspect this problem is generated by a short circuit on the keyboard. Before ordering a new keyboard, I was wondering if you solved the problem and how (software, keyboard replacement or motherboard keyboard connector problem?) . I would appreciate a quick answer. Many thanks.
