Certain keyboard keys broken

Question

A while ago, various keys on the left side of my keyboard began needing to be held down to work. After holding one of them down for a while, all of the keys would begin working as usual. Overtime, the time needed to hold them down for got longer and longer until I stopped being able to get them to work. The laptop was taken for repairs and the entire lower half was replaced. Recently, the issues came back and presented itself in the same way as last time, the keys are slightly different but still are all on the left side and include the space bar. The other day the keys once again stopped working entirely.

I’ve attempted reinstalling and updating the keyboard drivers, as well as reinstalling windows onto the laptop, neither of which made a difference.

I haven’t been able to find anyone else with my exact issue and i’m struggling to work out what it could be and how to fix it. Any advice or support would be greatly appreciated.

Hello,

Sorry you are dealing with this.

The symptoms you described are consistent with possible microcracks on the circuit board under the keyboard. Since the previous repair appears to have been only a partial repair, there may be additional damage elsewhere.

Driver or software issues typically do not behave this way.

To confirm whether the keyboard itself is the problem, test with the on-screen keyboard or connect a different keyboard through USB or Bluetooth. If the other keyboard works normally, that would strongly indicate a hardware issue.

I would avoid uninstalling or reinstalling drivers or software at this point, since it is unlikely to help and could introduce unnecessary new issues.
