I suggest you press the reset port (that is, the reset hole), find a toothpick, a ballpoint pen and the like, find the reset port of the flat body and poke it in, and then try to turn it on. If it doesn't work, poke it again and try again (you can also try to press and hold the power button 10 second or more to see if it can be restarted, and some machines need to poke 10 second or more to start).

If you really can't, you can only brush the machine. Tablet PC brushing steps:

① Download the firmware package of the corresponding model from official website (no matter what brand of your tablet is, you should look for official website).

Under normal circumstances, after the firmware package is decompressed, there will be many files in it, including a brushing tutorial. Just follow the tutorial. If you don't understand Baidu, ask other users.

(3) When sufficient power is needed, brush the machine.

④ Back up important files and software before brushing.

It should be noted that each brand's brush method and brush firmware package cannot be universal. Don't use third-party software to brush the machine. Only officially provided software and methods can be used. It is recommended to brush the machine on WIN7 and XP computers, and it is best to install drivers. WIN8 brush machine generally needs to turn off the forced signature of the driver to succeed.
