I also have an Asus Zenbook UX21E and am having the same problem! Also have had no luck with Asus tech support. For me, my open bracket has worked for nearly three months, and then all of a sudden I'm getting the page up thing too! I think it actually might be the numlock solution for me, as I plugged my laptop in to an external screen, keyboard and mouse to do a uni project last week.
Will try that, wanted mainly to say thanks for your help
Cheers.
