Hello Everyone,
Nothing is more frustrating than having a PC work well, and then doesn't after a software update. The steps to take are really tedious trying to identify a problem that was not there a second ago.
I checked first to find out if my hardware, the trackpad, is working. To do that, the easiest way is to enter safe mode in windows 11. If the trackpad happens to work, it would mean that it's driver isnt working normally, or there might be another driver that is conflicting with it.
Once I figured out nothing is wrong with my hardware, I started to check the device manager under the normal boot (had to use the touchscreen and keyboard, or an external mouse) for any device that has error. In my case, none had problems, just that my trackpad was missing. I uninstalled all vendor HID devices under human interface, and rebooted. Viola, the trackpad starts working.
Then went back into device hardware, and noticed that there are two mouse settings. I disabled wake up computer under power management for both mouse. From then on my laptop had no more trackpad problems. Hopefully Microsoft fixes the problem instead of passing it onto the vendors.
All the best
