I have a laptop (dell inspiron 8200) that exhibits a problem.
Sometimes the left Alt key doesn't work, however sometimes the OS thinks the key is being held down (while the physical key position has no effect). And sometimes (very rarely) the key works fine.
I firmly believe the problem is not due to the mechanical switch in the keyboard, because when it DOES work, it works so well, and the physical condition of the key is fine.
I reinstalled Windows XP and updated my CMOS to eliminate that as a possible cause, and the problem still happens. Plugging an external usb keyboard works fine, while the internal keyboard ALT key still has no effect.
Any ideas on how to remedy this problem?
