I have used the Asus (ZE551ML) before and have experienced tons of issues but not this one so I have to guess,
what I would do instead is try disconnecting the battery and reconnecting it (soft resetting it). Asus is known for their buggy OS (their customized android even destroyed my zenfone 2 lcd during an upgrade) and buggy apps even on PC. so Im hoping a soft would be sufficient.
and make sure you dont update the OS. I learned that the hard way.
Let me knw it that helps
