The screen on the laptop went out
But, just like in a computer, various unexpected errors can occur in a laptop. So, many users encountered the following problem: the laptop was working and suddenly went out. Or the laptop screen periodically goes blank. Let's try to figure out what can be done in such a situation. If your laptop screen has gone dark, try the old “old-fashioned” method. Restart your laptop by pressing the power button. Perhaps this will help. If not, then read on.
The laptop screen may go blank if the computer's power supply is not configured. You need to go to your computer's control panel, then select "Equipment and sound"and here you will need to go to the menu"Power supply".
After clicking on "Power supply"you will be taken to a menu where you can select one of several power supply schemes, or rather, the settings for this scheme. You need to select the one that is currently working. In our case, the “balanced” power supply scheme is selected.
In this menu, you need to pay attention to the time after which the screen will automatically darken or go dark. If you have it running for a very short period of time, then the screen might go dark due to these settings. In a good way, the screen will not go dark on its own if it has the settings set as in the screenshot.
By the way, it is worth noting here that the screen may suddenly go dark if you accidentally press hot key (most often one of the f keys), which is responsible for the screen brightness state. Try pressing some of these buttons.
Also, the screen may involuntarily go dark due to a lot of dust in the laptop. It would seem that this is not very realistic, but there have been cases when the dusty filling of a laptop affected the operation of the screen.
The problem may also lie in the drivers for the video card. Due to their absence or if they are not very new, the screen may lose brightness, and in some cases even go dark. In this case, you just need to update the drivers. By the way, it’s worth mentioning the BIOS here. It may also need updating.
The most unlikely reason for a laptop screen to go dark is the presence of viruses in it. There have been practically no such cases, but it is still possible. Check your system for viruses using your antivirus or healing utility Dr.Web CureIt. If none of the methods given here helped you, then try connect an external display to your laptop. For these purposes, the laptop has VGA, HDMI or DVI connectors. If in this case an image appears on the external monitor, but it still does not appear on the laptop, then you will have to take the laptop to a service center, since here the problems will most likely be in the screen matrix.
