Keys issue on laptop.
Keys issue on laptop.
I just replaced the battery and cleaned the heatsink and fan. It’s unclear if the issue started before or after because my laptop had been non-functional for weeks. After a factory reset, the problem is only with that particular diagonal row not working. I’m looking for guidance on what might be causing it.
On a laptop, the key matrix is usually linked straight to the motherboard using a flat flex cable rather than having the entire keyboard self-contained and connected through USB. If a connection gets disrupted—due to a misaligned, dirty, or damaged flex cable—the keyboard layout may stop working properly. You might have accidentally shifted something while handling the device.
