About Asus GL553VW restart under load/SOLVED/ - What is purpose of +VCCGT ? Hi, I know this is an old post but I have an Asus zenbook duo UX481FA which has very similar symptoms. When windows boots the laptop freezes either in startup or right when it hits the login page. I have 0V on VCCGT but am unsure if thats normal or not. Would appreciate if you had any suggestions on how to tackle this problem. Thanks.
