the dfklmosy keys stopped working on my old dell xps m1530
tried re-seating keyboard connector, no effect, any ideas how to fix or further troubleshoot...?
Is there any liquid spillage / physical damage on the system?
Replace the keyboard and check - if the issue is not resolved, then I would suspect a keyboard controller failure and the motherboard needs to be replaced.
I would personally suggest you to invest your money on a new machine than to repair this old system if it is a motherboard failure. However, that is your discretion.
