In the beginning, my OG Zenbook had beautiful white keyboard backlighting. I have looked everywhere I can think of to get instructions for restoring it. Half the time I'm told this model had no key backlight. There are no on/off switches on the F3/F4 function keys, but I'm not crazy. I remember remarking on the beautiful backlight. I wouldn't be surprised if Windows forcing a download initiated the problem. I'm going to be using this laptop on a new WFH job. Please let there be an ASUS whisperer out there who can help me!
