Question 1

Install fails or rolls back?

Accepted Answer

Confirm the chipset/SMBus controller drivers are installed first, run the Synaptics package as administrator, and check Device Manager for a pending reboot or unsigned-driver error.

Question 2

Touchpad not detected?

Accepted Answer

Enable the touchpad in BIOS/UEFI, verify the Synaptics device appears in Device Manager (including hidden devices), and reseat/check the touchpad ribbon cable if it is missing entirely.

Question 3

Version conflicts after Windows Update?

Accepted Answer

Roll back to the OEM-approved Synaptics driver in Device Manager, uninstall duplicate Synaptics entries, then reinstall the matching SMBus package and pause automatic driver updates if needed.
