What should I do if my computer has a black screen if I don’t use it for a long time?

The screen goes black when the computer is not used for a period of time because the computer is set to the energy-saving mode by default, and the system automatically turns off the monitor and enters sleep mode.

Set the computer sleep time:

1. Turn on the computer, and then open the computer’s settings options.

#2. Select "Power and Sleep" in the menu bar on the left, and then click it.

#3. Modify the two times under sleep to "Never", as shown in the figure below.

4. Save and then exit the settings to complete the operation, so that the screen will not turn black no matter how long it takes.

Extended information:

1. Computer sleep mode

"Sleep computer" generally refers to "computer sleep mode". Computer sleep mode is a mode in which the computer is in standby mode and can be set through the computer's "Power Options" menu.

2. Advantages

It can save power for you, and it is relatively "environmentally friendly". This saves you the tedious boot process. Increase the life of your computer.

3. Mode startup status

There are things that need to be handled temporarily, but it won’t last long. There are too many edited documents and opened web pages, but they have to be left for a while, and saving them is very troublesome. Where there are restrictions on the use of electrical energy.

New energy-saving mode The Windows operating system has long added standby, hibernation and other modes, and Windows Vista has added a new mode called sleep mode, but many people are still used to not using the computer. Turn it off completely.

In fact, by making full use of these modes, we can not only save power consumption, but also restore the system to normal working status in the shortest possible time. The definitions of these three modes are as follows: Standby. After switching the system to this mode, except for the memory, the power supply to other computer devices will be interrupted. Only the memory relies on electricity to maintain the data in it (because the memory is volatile , as long as the power is cut off, the data will be gone).

In this way, when you want to restore, you can directly restore to the pre-standby state. This mode is not completely power-free, so if there is an abnormality in the power supply during standby (such as a power outage), you will have to restart the phone next time, so any unsaved data before standby will be lost. However, this mode has the fastest recovery speed and can generally be restored within five seconds.
