Question 1

Install fails or rolls back?

Accepted Answer

Run the Synaptics installer as administrator. In Device Manager, uninstall the existing touchpad driver under “Mice and other pointing devices,” restart, then install the package matching your laptop model.

Question 2

TouchPad not detected?

Accepted Answer

Check BIOS/UEFI for a disabled internal pointing device. In Device Manager, enable “Show hidden devices” and look for the Synaptics PS/2 TouchPad; if missing, scan for hardware changes.

Question 3

Version conflicts after Windows Update?

Accepted Answer

Windows may replace the OEM Synaptics driver with a generic one. Roll back to the previous driver, then set your OEM package as preferred or reinstall it after updates.
