I have the same laptop model and problem. I actually started a new thread on this because I hadn't noticed this one.
Also, if I shut down the laptop I completely lose the gesture functionality. It can be restored by reinstalling the driver or by removing it. Shutting down and rebooting removes the gestures again.
Edit: After some testing, I managed to keep the gesture functionality after shutdown by turning off Windows fast start-up. But restoring it after sleep still requires a reboot.
