Question about Dell Precision M4400 Notebook
Keyboard has stopped working most keys not working
If you have access to an external keyboard, plug this into your laptop USB (or PS/2) port. If this works you may have a faulty keyboard on your laptop.

The particular keyboardpart must have gone. I had his problem with my Dell some years back. I removed the entire laptop, removed and reinstalled teh keyboard wire to the motherboard..and the problem did not arise. Happens whenever over heating occurs.

yes it is probably dead for some reason ..the probabil cause it is a contact for a area..and this is a used but a good price one ...that works ..
here are another if that one seams not on your taste ...among them are even new ones..
to actually change it ..you have to remove the front part that covers the hinges and holds the buttons ..(see that it have spots to insert something on the F1 and f11 keys ) than remove the keyboard itself by pushing it a little toward the lcd..and up..it is snapped in place and slides in a little...Than it has just a ribbon that removes by pulling the safety plastic ends a few mm out ...
