Hello - the trackpad on my Acer Aspire e11 es1-111m-c3cp used to work beautifully on 2015 version of Windows 10, but after a major install to an up-to-date Windows in 2020, the trackpad didn't work at all at first, so in BIOS I changed Trackpad from Advance to Basic and now it works a bit... but not much... no gestures, right-click doesn't work properly, barely useable.
In Device Manager the trackpad is NOT PRESENT. In "Mice and other pointing devices" there is "PS/2 Compatible Mouse". And if I "Show Hidden" under "Human Interface Devices" is "USB Input Device".
Any ideas please? Thanks.
