Answer to: Why is my Asus Transformer T100 not turning on?I had the same problem after having my tablet for 4 months. I called ASUS and they had me unplug my tablet, hold the power button down for one minute, plug the charger back in, and try turning on the tablet. It worked for me! They told me that my tablet was in sleep mode for too long which caused it to think it needed to charge even though it was fully charged. Hope this helps!
