How to solve the problem that the tablet computer of Reading Lang students can't be turned on?

Lang's solution to reading without turning on the tablet is as follows:

Tighten the battery and wait for one minute before reinstalling the battery.

The tablet is dormant. If it is useless to wake up any operation, press and hold the power supply for 5 seconds and wait for the system to automatically cut off the power supply.

The tablet will have a small button to restore, which is hidden on the side or back of the tablet. Find the word "reset", insert a little thing and press it.

When the tablet crashes, don't be too anxious to operate. The general waiting time is about 30 seconds. If there is no response after 300 seconds, please touch the screen with your hand or press the back key. This will soon prompt the application not to respond, wait or close-just choose close.
