Question Windows 11 - Touchpad erratic after screen turns off Is there something else I can do to test if this is not a software issue? It seems strange to me that my trackpad is not working anymore after only a couple of months since I bought it. The last thing I did was to mount the cable and test every pin (the ends on the rear of the sockets, soldered to the motherboard and to the trackpad respectively) with a multimeter, and guess what? Everything worked, there were no obstructions and the signal should pass with no problem. Thinking I could have not mounted the cable properly, I then disassembled the laptop again and tried to fit the loose end of the cable in the socket in a variety of angulations, depths etc., but it still wouldn't work. I ran lspci but there was no entry about the touchpad. I then tried to see if Arch Linux would recognize it instead, but with no luck. I thought it was something trivial like I had accidentally hit FN+F9 (the key combination to turn the touchpad off on my laptop), but it came out that Windows wouldn't even recognize the trackpad at all, as if it was unplugged from the motherboard.
Some time later I realized instead that it didn't respond anymore, and that Windows didn't even show the cursor after the boot if the USB mouse wasn't plugged in. It seemed to work fine, and since I usually use a USB mouse when I'm at home, I didn't bother to check if the touchpad was working. Some days ago I bought a caddy to fit a second HDD in the optical drive bay, so I disassembled my Asus laptop (in this process you have to detach the touchpad's cable from its socket), installed the caddy and mounted everything back.
