Hello, how to operate the portable black screen

1. Double-click the screen in the black screen state to light up the screen.

2. The black screen is in the state and swipes according to the predetermined gesture, which can solve the state lock and enter the preset application.

3. If the swiping gesture is consistent with the preset gesture, the touch screen of the mobile phone will make the corresponding selection. For example, go up to the camera interface, go down to the dial-up interface, go left to enter the SMS comic side, and go right to enter the browser.

4. The black screen gesture supports screen sliding operation in the case of the mobile phone standby black screen, and the user can directly wake up a certain function of the mobile phone or the corresponding software through the gestures set inside the mobile phone.

If the screen is black, there are many situations, first of all, check them one by one, the following is for your reference.

1: The graphics card, the black screen is likely to be a problem with the graphics card driver, or it is possible that the graphics card is not in normal contact. You can update the driver in Jinshan Guardian - Treasure Chest - Heavy Loading Master - Install Driver.

2: It may be that the system boot is relatively slow, because there are many boot items, and the system needs time to boot. Therefore, it is recommended to use Kingsoft Guardian to prohibit unnecessary startup items.

3: The black screen may be a Microsoft genuine verification failure, please verify the serial number 4: It may be a failure of the system itself, this depends on whether the problem is serious, try to reinstall!
