either your battery is shot as in dead or your charger is faulty
you could try to charge it using a usb lead in your computer or another usb port to see if that works , or try another charger to eliminate your lead /charger you are using

The charger has a function that restores the battery operation parameters by discharging then charging the battery a number of times. Refer to charging instructions in the pack but I think the cycle is a 3 hourly one, time to charge from a full discharge. If the charger thinks the battery is dead then it will try to recover the battery using this process. You may have left the charger on long enough to charge then also discharge the battery.
Start again and charge for the time in the instructions ONLY, if you are not sure of the time try it for an hour, then without disconnecting the charger turn the unit on and take particular note of any screen messages, if any.
You should be able to continue as normal now, but still be aware of the time you are leaving the charger connected for, as it may take some time before it returns to normal operation and stops trying to recover what it thinks is a dead battery.

The battery is dead and cannot be recharged. Replace the battery.

HI Jessica,

please let it charge 10-20mins to pop up the battery voltage level.
if it is not turn on anymore please go fore the warranty replacement.
regards.

i have a problem with my nexus7 and it want charge or turn on please help me with this problem

friend please give a pawor shok to bettery.i think then he started to work.if she not working then please try a new bettery.

Try removing the battery and see if it will boot without it
Then check the caharger, charging light should be green and steady on the charger itself
If it is flickering, it meand power is not making a circuit, test charger jack with a DC volt multimeter with one probe to the outer side (earth) and one on the inner (positive). If this is ok, check the charging socket is not loose (if it is, will need replacing).

After that, suspect the power strip or charging / powerboard is dead on the motherboard
