Question
Just got my X220 (i7, 4gb, 300hdd) a few days ago; and I notice a beep noise after hitting a certain combination of keys. The beep occurs every time I hit a 3-key combination consisting of any key + the key above + the key to the left.
For example the beep occurs, when I write "fre" or "vfd" or "loi".
But it also occurs when typing "ouh" or "oun" or "oum". The weird thing is: it only beeps when I type the 3 letters quickly. If I type slowly, no beep noise is made.
After the beep, nothing else happens. I can continue writing and no error message or anything else comes up.
Answer
It is a normal with ThinkPads, you can turn off Keyboard Beeps in the BIOS menu.
- Press F1 at the ThinkPad POST screen.
- Highlight Config using the arrow keys, and press Enter.
- Highlight Alarms using the arrow keys, and press Enter.
- Highlight Keyboard Beep , and press F5 to change the value to [Disabled] .
- Press F10 to Save and Exit.
- Choose Yes to save your changes.

The ThinkPad keyboard has 2-key rollover, and will jam on certain 3-key combinations.
