When charging/ Im getting a charging battery icon with a question mark in it. Isnt charging & no longer will power up. ???
I also experienced that before with my tablet. I found out that there was an issue with my charger. I got a new one and everything was ok after.
But if you replace your charger and the same thing still happens, then it could be the battery. Contact Asus to find out how you can get your tablet repaired.
