While it is possible for there to be driver update issues that cause trackpad issues on the Asus, the most common issue is from folks accidentally hitting the F6 key -- which disables the touchpad on the Asus (the same feature exists on the Lenovo with the F8 key). Historically, we've mostly seen this happen on the computers of 6-9th grade boys for some reason ?
If F6 or FN + F6 doesn't re-enable the touchpad, please open a ticket.
