I own a Lenovo IdeaPad 3, and I used to run Windows 10 Pro (I purchased a code, this isn't native on my PC; don't know if it matters). Wanting to test the 11 Pro beta version, I upgraded and as soon as I did, the touchpad stopped working.
On the device manager, the is a new section called Keyboards, with two Lenovo Keyboard Device, one of which has an error mark. The touchpad driver (formerly HID Complient Touchpad driver - or something similar) is not totally missing.
The device manager finds no driver updates, as does Windows Update, as does Lenovo Vantage (from where Lenovo updates the BIOS and certain drivers itself). I tried to discharge power by turning off the computer and pressing the power button for 40 seconds. I've deleted the corrupted drivers and restarted my PC, but they were reinstalled in the same state. I tried to manually reinstall the drivers from Lenovo's website. The two things I mean to try last are to roll back to Win 10 / run system restore / hand the PC over to a Lenovo technician.
The touchpad options are likewise missing from the settings, though this could be some rearrangement of the settings in Win 11, I don't know.
Lenovo support couldn't resolve the issue remotely, which is why I address the masses. Any idea?
