That's a BIOS update I believe and would leave well alone unless you know what you are doing. Granted BIOS updates are easier to do nowadays but if you get it wrong you will have an expensive doorstop. Check in device manager under mice and other pointing devices, select the touchpad and see if you can roll back the driver first. Reboot and see if it works now. It might have been an incompatible driver downloaded via windows update. If that doesn't work there is a driver Version V2.2.7 from here to try, but from the same link, and considering how young the laptop is, I would email Asus with your query. Customer service top right. If still no joy take it back under the warranty from where it was purchased. They will repair it for you.
