I have had my G9 about 1 month. Am experiencing an issue where the touchpad will intermittently lose functions. Initially it seemed that just the swipe functions would stop working. Usually a restart would restore them. More recently the left click button has also begun to intermittently malfunction co-occurring with the loss of swipe function. When this occurs it might take 2-3 depresses of the left click button for it to respond - though sometimes it works first time. Seems to occur in all apps / games. Drivers all up to date. Not result of disabling touchpad.  Still able to manipulate cursor and touch click on touchpad. Not sure if its a hardware or software issue. Touchpad often works properly again following restart or even putting laptop to sleep (low power mode) and then waking up.
