Hi - I upgraded our Switch 10 to W10; it had earlier been having issues with the touchpad mouse pointer going straight to the top left corner of the screen & not moving from there, which I thought I'd cured with the latest BIOS update. The upgrade went fine (used a USB stick for storage), & W10 worked fine. However, the Switch seemed slower, so when the touchpad started playing up again, & within the 30-day period, I downgraded it back to 8.1.
However, the touchpad mouse & buttons still don't work, & I have to use a USB mouse. I've used the platform installer from Acer support; no pointer appears on screen, & the touchscreen works (I can scroll this window up & down, but only 'directly', not by using the scroll bars, & I can't load programs by touching their icons. Oddly, Device Manager now shows 'Pluralinput' for both mouse devices listed.
Oh, & the Start button often doesn't work . . .
Any hints? What should the mouse drivers be called in Device Manager? Alps? Synaptics? They were just MS HID-compliant drivers under W10.
Thanks in advance for any help
