Dell laptops can turn off the screen without making it light up by using the following methods: 1. Use shortcut keys
Most Dell laptops are equipped with a shortcut key combination to quickly turn off the screen, typically consisting of the "Fn" key plus a screen icon key (such as one of F1 to F12, depending on the computer model and brand). Just press these two keys simultaneously, and the screen will immediately turn off while the computer will continue to run. Press any key or move the mouse again, and the screen will light up again. 2、 Through system settings
For Windows system users, the screen can be turned off without turning on by adjusting the power settings:
1. Enter power settings: Open "Settings" or "Control Panel" and find "Power Options".
2. Adjust plan settings: In the power options, find the currently used power plan and click "Change Plan Settings".
3. Set screen off: On the "Change Schedule Settings" page, find the "Turn off monitor" option and set it to the time you want (if you want to turn off the screen immediately, you can choose "Never" and manually turn it off, but this is not direct). However, a more direct approach may be to find an option to 'immediately turn off the monitor', or to achieve this function through other means such as using third-party software. 3、 Closing operation
For Dell laptops that support sleep mode or screen shutdown, simply close the screen to turn it off. However, the specific effects of this behavior (such as hibernation, sleep, or simply turning off the screen) depend on your system settings. You can adjust the setting of "When closing the cover" in "Power Options", and select "Do not take any action" or "Turn off the monitor" to achieve the effect that the screen does not light up after closing the cover. 4、 Using third-party software
There are also some third-party software that allow users to more flexibly control the screen display of their laptop, including functions such as timed screen shutdown and automatic screen shutdown based on specific conditions. These software typically provide intuitive interfaces and rich settings options, suitable for users who require highly customized needs. matters needing attention
