Help...my keyboard is locked up...I can't type anything. I think know I hit a combination of keys by mistake and now can't type at all. Does anyone know how I can unlock it. I have a Dell Inspiron laptop.
To solve this problem: Press 2 keys at the same time: "FN" (next to the CTRL key, lower-left of the keyboard) and "num lk", which is the upper-right of the keyboard (it is on the same key as "scroll", and is next to "F12"). This will either turn on or turn off the "Num Lock" function.
