Tablet won't charge

If your tablet computer does not charge or there are other problems with charging the battery of this device, there are several reasons for this. This may result in a breakdown of the charger, failure of the wire, connector, power controller, battery or firmware.

Why is my tablet not charging?

The main reasons are as follows:

1. There is no required voltage in the electrical network. This may be the reason that the tablet is not charging, or the power supply is in “long mode”. Unplug household appliances that consume large amounts of electricity. And reconnect the gadget to the power supply.
2. If the device remains on for a long time and at the same time the panel on the back side becomes very hot, the power supply controller has failed. This requires repair in a workshop using special equipment. Sometimes it is possible to restore the controller's operation using thermal positioning and then reinstall it in place. Often the cause of this breakdown is the moment the element is displaced from the contact microcircuit after a fall.
3. Software failure. In some cases, the software is a kind of conductor of incorrectly issued commands, this disrupts the power supply process. Reflashing the tablet can help fix this problem.

Attention! What exactly to do if there is no power depends on the reason.

How to find the reason

Not many users pay attention to the fact that new Android gadgets need to be recharged using special technology. Store salespeople talk about this, but this information is almost immediately forgotten. The tablet computer must be completely discharged the first 2-3 times before turning off and only then installed on power.

Often this condition is not met; the device is connected when the energy level drops to 30-40%. The device remembers the difference until the battery is fully charged and subsequently charges exactly the same amount, regardless of the level of discharge of the battery. So it soon loses capacity, and tablet owners do not understand why the battery drains quickly or takes a long time to charge.

Another recommendation is that you don’t need to leave the tablet on power overnight. Naturally, it will not burn out. But heating still occurs, this can lead to battery failure. This is especially true for devices in cases.

Attention! It is advisable to use only the “native” memory. The use of Chinese devices also leads to overheating and malfunction.

Troubleshooting

Most often you need to do the following:

1. Incorrect operation. Constantly completely discharging the tablet's battery, this significantly reduces its service life. The gadget does not turn on and charges slowly due to the battery being discharged because it was not used correctly. You can still revive the battery in an alternative way - disassemble the device, remove the battery and recharge the battery, bypassing the device controller.
2. The device is probably not working properly. For Chinese tablets, this is the most vulnerable spot. As a rule, this problem is solved with the help of a tester.If there is voltage in the device, but the current is not constant, then the gadget will still charge, but in this case the power supply will only be 3-4%. Tablet batteries are quite powerful and will require the same power from the device. A weak charge can even damage the gadget. The easiest way to check the memory is to power the tablet from the laptop. If everything is charging, then you need to replace the device.
3. The voltage is present, but recharging does not occur. The simplest thing that could happen is that the contacts are dirty. As a rule, a lot of dirt collects here. Visually inspect the connector where the device is inserted, especially the plug that connects to the gadget. Try moving the wire. Probably, in a certain position the tablet will still start charging. Accordingly, the reason is in the connector. It happens that the contact is either bent or broken.
4. If neither cleaning the connector nor “wiggling” could help, then the connection between the board and the battery has probably come loose, or the screen cable is coming away from the device controller. It is not advisable to disassemble the device and determine the voltage on the battery. It is necessary to take the tablet for repair.
5. Another common reason for the lack of battery power is a fault in the power supply circuit. The cause of the malfunction is the charger, which supplies the battery with a current much higher than necessary, either with constant signals or with one strong impulse. The gadget's power supply circuit is disrupted, making recharging physically impossible. The tablet needs to be taken in for repair. It’s not worth fixing this problem yourself, especially if the gadget shows power, but the battery is not charging.

Any owner of Android devices must be careful about the gadget, “train” the battery and have several spare devices. In this case, any breakdown can be easily dealt with using simple instructions, and the tablet will last for many years.
