The tablet does not charge

If the tablet computer does not charge or there are other problems with recharging the battery of this device, there are several reasons for this. This may damage the charging, failure of the wire, connector, power controller, battery or firmware.

Why the tablet does not charge

The main reasons are as follows:

1. There is no required voltage in the mains. This may be the reason that the tablet does not charge or the power is in “lazy mode”. Disconnect household appliances that consume large amounts of electricity. And reconnect the gadget to the mains.
2. If there is a long device and at the same time the panel heats up very strongly on the back side, the power controller is out of order. This requires repair in the workshop using special equipment. Sometimes it is possible to restore the controller using thermal positioning with further installation in place. Often the cause of this breakdown is the moment of displacement of the element from the contact chip after the fall.
3. Software crash. In some cases, the software is a kind of conductor of incorrectly issued commands, this disrupts the power process. Flashing the tablet can help fix this malfunction.

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

How to find a reason

Not many users pay attention that new gadgets on Android need to be recharged using special technology. Sellers in the store talk about it, but this information is almost immediately forgotten. The tablet computer should be completely discharged the first 2-3 times before shutdown and only then installed on the 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 battery sparseness. So she soon loses capacity, and the owners of the tablets do not understand why the battery quickly runs out or takes a long time to charge.

Another recommendation is that you do not need to leave the tablet overnight on food. Naturally, he will not burn out. But heating does occur, it can lead to a malfunction of the battery. Especially this applies to devices in cases.

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

How to troubleshoot

Most often, you must do the following:

1. Incorrect operation. By completely discharging the tablet’s battery, this greatly reduces its service life. The gadget does not turn on and slowly charges due to battery drain, because it was not properly used. Still, you can 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. In 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, and the current is not constant, then the gadget will still be charged, but in this case, the power 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 option to check the memory is to power the tablet from the laptop. If everything is charging, then you need to replace the device.
3. Voltage is present, but charging does not occur. The simplest thing that can be is the contamination of contacts. As a rule, a lot of dirt is collected 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 begin to charge. Accordingly, the reason is in the connector. It happens that the contact is either bent or broken.
4. If neither cleaning of the connector nor "stirring" could help, then the connection between the board and the battery has probably moved away or the screen cable has moved away from the device controller. It is undesirable to disassemble the device and determine the voltage on the battery yourself. It is necessary to carry the tablet for repair.
5. Also a common reason for the lack of battery power is a violation of the power supply circuit. The cause of the malfunction is the charger, which supplies the battery with a current much higher than necessary, at the same time either with constant signals or with one strong pulse. The power supply circuit of the gadget is disrupted, making recharging physically impossible. The tablet needs to be carried in for repair. It’s not worth fixing this hollow yourself, especially if the gadget shows power, but the battery does not charge.

Any owner of Android devices must be careful about the gadget, “train” the battery and have several spare devices. In this case, any damage can be easily dealt with using simple instructions, and the tablet will last more than one year.
