Hi margatehani, Good day. Do you long press the power key or not? If not, please kindly help me check this matter under safe mode. (For instructions, please refer to the link: http://www.asus.com/zentalk/forum.php?mod=viewthread&tid=3105&highlight=safe%2Bmode) If this problem still appears, this might be a hardware issue, I would suggest you bring your phone to a local service center for a check. Sorry for any inconvenience this may cause. http://www.asus.com/support/Service-Center-All-Countries/

Just a short press. As long as the screen goes off, phone automatically turned off. Then if you turn it on battery life decreases about 15%. What a waste.

Hi margatehani Thanks for your reply. The power button might be caused by a hardware issue, I would suggest you to backup phone files and bring your phone to a local service center for a further examination. Do you use this Version 8939 of UnlockTool? https://www.asus.com/Phone/ZenFone-Max-ZC550KL/HelpDesk_Download/ Please show me your error screenshot and show me your serial number by PM. (settings> system> about phone > status > serial number) Thank you.
