My tablet wont work at all

Try this
Plug in the charger
Hold down Volume + and Power buttons at the same time for at least 15 seconds. Remove the charging cable from the tablet, then plug it back in.

Either the battery or the charger is shot.

If the tablet works while plugged-in to the charger, yet dies immediately when the charger is disconnected, it means that the rechargeable battery in the tablet is dead.
If the unit will not turn on at all, even with the charger attached, the charger itself may have failed, or the unit may be having other issues.

Try connect to PC. If PC find it - its ok, then you need reinstall windows or android, if not find, something wrong with microschemes

Try another charger, or the battery may have to be renewed

Most likely you are using an aftermarket charger. You may want to purchase another or buy and OEM charger.

At this level of charge their is not enough to start the boot process , if it doesn't charge at all their may be a fault with the Battery cell , however i had a similar issue, just leave it for a while, if their is still no indication that its charging or it wont turn on their could also be a problem with the Start Button

There should be a tiny reset button or pinhole (use a straightened out paper clip). If reset button/hole itself does not work, try pressing it while holding down the power button at same time. Otherwise, it sounds like you have a battery/charging issue (try another charger cord if available).
