Dell inspiron 15R's numpad Enter key suddently stopped working ! The keyboard layout is the same, I don't think something changed !
Any ideas ?
We think we have found that this is a hardware problem. The following tips might be useful for other users with similar problems, in order to find out, if it is a hardware or software problem.
If you run the on-screen keyboard onboard, does the corresponding key work?
If not installed install with
sudo apt-get install onboard
If you boot the computer live, 'Try Ubuntu' from a USB drive or a DVD disk? Does that key work? Or try live with another linux distro.
If you dual boot with another operating system, for example Windows, does that key work in the other operating system?
