How do I disable touchpad on Asus Laptop?
Check your Function or “F” keys. One of them should have a graphic of the touch pad with a line through it. Hold down the Fn key and press this one to disable or enable your trackpad.
Fn + F9 used to work, but every windows update enables it again. This latest seems to have disabled this combination completely. It’s very annoying and causing me to lose a lot of work.
