Learning machine maintenance method

1. Pay attention to waterproofing All electrical products have a common feature, that is, they cannot enter water. There are IC appliances, DC circuits, and touch screens in the learning tablet computer, and the joints of the shell are not waterproof, so once you learn the tablet computer If it falls into the water, or gets the water on the learning tablet, it is possible that the water will fall into the circuit board, which will cause a short circuit between the IC pins and leakage. Once the electricity leaks, there will be abnormal noises whether it is a Taiqi notebook or other learning machines.
2. Note that the shells of hard objects are all plastic products, even the better BBK learning tablet is also made of plastic shells. If you hit the shell with a hard object, it is likely to smash the shell or break the shell. If it is serious, the circuit board will be damaged and cannot work normally. Or cause the parts of the Taiqiqi notebook to fall off and make abnormal noises when shaking.
3. Turn off the battery before inserting the SD card. Usually, when inserting the SD card, you should turn off the power first, and then turn on the power after inserting the SD card, because the SD card has a hot-swap function. The copper contact of the learning tablet computer rubs and ignites, or the power is cut off instantaneously and the content of the SD card cannot be read. Therefore, these problems can be avoided after plugging in and then turning on the power, thereby protecting the service life of the SD card.
4. Remove the battery if you don’t use it for a long time. If you don’t use the tablet for a long time, you should remove the battery. The tablet uses the battery. If you don’t use it for a long time, there will be a problem of leakage. If you don't use the tablet for a long time (more than 1 month), it is safer to remove the battery.
