My tablet is not charging beyond 62% - Tablets & eReaders

hi.

How do turn my tablet back on Google Search

If it truly is the connector in the Nabi, you're in a bit of a jam. But, the power cords I find are very finicky. I have two Nabi's and each has its "preferred" charging cable. One cable works better than the other on each tablet. Before attempting any major repair, try another USB charging cable. You can get the cable for under $4 on Ebay. Make sure you have a high powered USB source (2 Amp or 2000 milliamp) or it won't provide enough juice to charge the tablet. Beyond that, I also sometimes have to "position" the cable just right, twisting the connector and cable till I get the red charge light to stay on. Often this requires I fully power off the Nabi, not just put it into stand-by. Good luck.

You have a battery failure.. You need to replace the battery, its worn beyond its life cycle and therefore cant take charge.

Good evening
This happened to my iPad. When I discovered that there were many programs open, I closed them and it charged.
hope this works for you as it did for me. Some one told me that it was a good idea to plug the tablet to a computer and charge it that way.

try a different USB / Charging cable. If still not resolved, replace the battery.

The battery can't hold the charge. Defective.

Or the charger is defective and not outputting enough voltage.

This can be tested with a voltage tester. The charger should be outputting 5 volts.

A good purchase is an inexpensive voltage tester. Can be used for so many things.

Sounds like battery is faulty. Replace it and check.

You may need to reboot your tablet. Try turning it off, then at the same time, Press the "On" button, press the volume up button at the same time. Keep holding till you see the little Android light up, and you should see your tablet come back up. I think your tablet may have froze up on you. Freezing screens is common on these types of devices. Good luck.

Older tablet batteries can begin to give out after less than two years. If a newer tablet shows this symptom, it could be that the battery monitoring software has lost sync with the battery. If a complete discharge and recharge cycle shows the same result, then a failing battery is likely. Tablet batteries are technician replaceable only and then only if they can be obtained from the MFG.
