Lynne, You may have ran battery down too low and cannot take a charge from Asus a/c wall charger and will not power up. Try this, 8 hour trickle charge your tablet from a low voltage/amperage connection, plug to PC USB port to the charging connector on your tablet, or use a low power phone charger 5 volt/500 ma. From forums I have read, lithium batteries do not like to be drained fully. Good luck.

I hope this helped you out, if so let me know by pressing the helpful button.
