Assuming that you charger is not defective, and that you have no other electrical issues, then if your battery has been allowed to completely flat line, it may no longer accept a charge from the normal wall charger. Then you can try to trickle charge your tablet from a low voltage/current source, such as a USB port or a low power phone charger (5v/500ma). Try a trickle charge for 8 - 24 hours on your tablet. After that try your normal charger and see if it will now charge properly.
If that does not work, and you have previously ruled out your charger, then I would suggest contacting the manufacturer, as it is likely some other fault, either with the battery, or the tablet itself.
Turned off the tablet, unplugged the charger and kept the tablet off for about 30 minute to one hour, plugged in back the charger, then turn on the tablet. After that I you might see the tablet started charging. Good Luck.
Lithium ION batteries are usually rechargeable. The use mode for these batteries is that there are a set number of recharges that equate to the life of the battery. Usually that life is approximately 1,000 charges.
If you use your battery to 50% then recharge, you can do this ~2,000 times. As the life of the battery is used up, the maximum charge lessens which means where you may have had 8 hours of play time when the battery was new, you will only have 6 hours as the battery life is used up.
In order for a Lithium ION battery to recharge there must be at least a small amount of charge left as a "seed" for that recharge. If you drain a L-ION battery down to zero, it may never recharge again or the max charge will be reduced to an insignificant amount of the original full charge. eg instead of 8 hours you may only get 15 minutes, or 5 minutes, or no minutes.
You are much better off recharging when 50% depleted than using it up til your product stops.
L-ION batteries cannot be repaired only replaced. Most cheap products using L-ION batteries cannot have their batteries replaced.
hmmm, sounds as if the battery had dropped below it normal 'low' charge, therefore it may not appear on the charging circuit (as if it were missing). This sometimes works for me. Put the tablet in your freezer for at least 6 hours. Lowing it's temperature sometimes will help bring a 'dead' battery back to some life, at least enough to get it back on line with your charger.
You need to check battery to see if the battery has correct voltage. Their should be on the battery the number for voltage of battery if battery is not at suggested voltage then check for tablet with voltage meter to see if the tablet is charging at correct voltage. If battery is at correct voltage then something is wrong with tablet. If battery is not at correct voltage then probably battery is bad. Let me know for further assistance
1.Check the device's battery level for at least two bars of strength. 2.If the battery level is low, charge the battery. 3.If the issue is not resolved, remove the back cover. 4.Remove the battery. 5.Wait 10 seconds. 6.Press and hold the W key. 7.While pressing down the W key, re-insert the battery. •The device restarts and after approximately 15 seconds, the 'Recovery' screen appears •Release the power button but *continue holding the home button*, for another 30 seconds.
