[SOLVED] My tablet won't charge.
We often get questions such as " My tablet has stopped charging & I have ruled out the problem being either the charger or the cable. What do I do?". If this happens to you, then...
Possibly your battery has been allowed to become flattened to the point where it cannot accept a charge from the wall charger. the best thing to do is to try and trickle charge your tablet from a low voltage/amperage connection. Either a powered on PC USB port to the charging connector on your tablet, or from a low power phone charger (5v/500ma). It has been pretty well documented that lithium batteries do not like to be drained fully & it may be that the battery in your tablet has drained so low that it cannot accept a charge from the Asus a/c charger.
Try a trickle charge for 8-10 hours (or longer) on your tablet & see if that gets enough charge into your battery to enable it to recognise & accept a charge from the a/c charger.
The only other suggestion, other than contacting Asus to arrange for a hardware repair, is to face opening up your device (if it is out of warranty) & checking the cables are connected correctly & possibly replacing the battery.
