    Some Acer laptops have a setting for touchpad in the bios - Advanced or Basic

    Make sure it's set to basic

    I had 2 Acer laptops recently with the touchpad not working and it was the setting in the bios set to advanced

        Try flashing the BIOS for one - I had a 5551G on which no touchpad would work - Synaptics didn't even register as a device, and ELAN showed up as Synaptics.

        Flashed the BIOS to the latest version - touchpad started working (ELAN) as intended. Didn't try the actual Synaptics TP as I've decided not to fiddle with something that started working.

            Hi Just got another Acer E5-511 touchpad not working and not detected in device manager - no option in the bios to select basic/advanced

            Bios was on v 1.03 - updated to 1.10 and option appeared in bios - set to basic and now working ok.

            Have you tried a bios update?

                  Is the touchpad driver installed under HID or mouse if yes download the latest driver from acer (windows 10 64 bit I assume) uninstall the driver currently installed and select remove driver the use the downloaded installer.

                    Acer E1-571G Q5WVH LA-7912P Rev 1.0 Bypass Touchpad Requirement
                    by uintptr
                    Hello, i have Q5WVH LA-7912P Rev 1.0 motherboard on my old PC. I accidently broke the touchpad things when replacing the back and up case. After doing that my motherboard going to blinking orange light on LED2. When I properly seat that touchpad thing, it occasionally boots. I think the problem is because of this. I don't have a soldering iron, so I can't solder it there. Since I'm going to use the computer as a server, I don't need a touchpad. I'm also leaving a photo for better understanding. I need to short-circuit it and make it work all the time. Which pins is for short-circuit? Thank you....
