I also have an Asus laptop with sleep issues. Different sleep issues I suspect... A 10ish year old Q535UD (aka Zenbook Flip 15 I think). Mine has an issue going into sleep: it goes dark and inactive, but instead of powering down, it actually powers up and starts getting warm. Only solution is to hold the power button and do a hard reboot. It’s a different WiFi device than the article’s laptop, but could be a related issue. I’ll probably never know as I had to eventually remove the battery for safety reasons, so now I use hibernation. No issues with that.
