I have an ASUS laptop model: N43S
I used fn-f9 keys to disable my touchpad, and after I pressed these two keys, a picture of a locked touchpad appeared on the screen but the touchpad was still working.
So I went to control panel -->
mice and other pointing devices-->driver
but the “disable” button was disable too.
I should disable my touchpad because I have to type my thesis and the touchpad is a big problem for me. Please help me in this case.
