You turned on your laptop by pressing the power button. You could hear the fan of your laptop whirling. And, as usual, the indicator lights flickered. Then you waited for something to appear on your laptop screen. But after a while, you saw something terrible: there's nothing visible on the screen. Your screen is completely black!
Here are possible reasons why your laptop screen is black:
The computer is not starting up. Even if you don't see anything on the screen, listen for noises that indicate the laptop is starting. If it's completely silent, therein lies the problem.
Problem with the laptop's battery. A laptop battery might create issues with booting and screen display. Even if it can be charged to full capacity, the battery may contain a flaw that causes it to mess with the laptop's startup process.
The laptop is overheating. When a laptop overheats, it usually shuts down. However, it may just shut off the display by limiting power to the GPU.
It's a hardware problem. Common hardware problems such as a loose or unconnected cable, a defective LCD screen, a problem with the CCFL or backlight, and so on might potentially cause the display to go dark.
Laptops are designed to be portable, which is where the issue arises. They get bashed, dropped, have liquid spilled on them, and are subjected to a variety of other ordinary incidents while being moved. As a result, laptop problems such as the screen going blank are rather common.
When you switch on your laptop, and the screen goes dark, these could be some of the reasons why:
The brightness control has been deactivated. Function keys are found on laptops. These are keys that allow you to access particular features, such as the brightness of your screen. Assuming your laptop has power and is switched on and operating, try increasing the brightness setting to see if this addresses the problem.
There is an external monitor that has been switched off. Do you have an external monitor? Check that it is switched on. Next, check to see whether your external monitor is configured to display a black screen since this might be the source of the problem.
The screen is damaged. Your laptop's screen may be dead. This is rare, but not unheard of. What is most plausible is that your screen is dim, but the image is still there.
Don't freak out if your laptop screen is black when you turn it on. Listen closely. Can you hear it running? If so, you can certainly fix the problem.
Here are 4 ways you can repair a running laptop with a dark screen:
Perform a hard reset. When your laptop is having difficulties starting up or otherwise misbehaving, you can hard reset or factory reset it. However, keep in mind that this process deletes data and programs, although it frequently fixes black screen issues.
Test the display by connecting an external monitor. When there is an issue with the LCD backlight or a damaged graphics driver, the screen may remain dark. Connect an external monitor and reboot the laptop to test the display. This test is useful if the screen is blank but you can hear the laptop running.
Reset the memory modules. A loose memory module frequently results in a laptop not showing a picture. A black or blank laptop screen may be resolved by resetting the memory modules. You may eventually get the screen to function by disconnecting the AC adapter from the laptop, unplugging and resetting the memory module, and reconnecting the AC adapter to the laptop.
Restart your computer. If your laptop powers on but no display appears, you may refresh or reset it to reinstall Windows without impacting your files, programs, or preferences.
Though black laptop screen issues are quite common, they can still be annoying or even frightening. But don't be alarmed. This problem can be fixed. Here are a few things you can do:
Restart the explorer.exe process. If the explorer.exe process on your laptop is closed, you may get a black screen. It is a process that handles your operating system's desktop, taskbar, and so on. Closing it may render your desktop and taskbar invisible, resulting in a black screen.
Enter safe mode and undo any modifications you've made recently. You may have made changes to your system settings or installed an application that is unsuitable to your operating system. You can reverse these modifications by booting your laptop into safe mode.
Do a hard reset. Hard resetting your laptop will erase all of the information in your memory as well as any changes made to your laptop.
Reinstall your memory. It's also likely that your laptop screen problem stems from an issue with your laptop's memory (RAM). Try reinstalling your RAM to see if it fixes the issue.
If you can hear your HP laptop operating and see the lights and indicators lighting up, but the display is still black, you can try a few troubleshooting steps.
They are as follows:
Adjust the brightness. Make sure the brightness of your laptop screen isn't set to the lowest setting. Increase the brightness and see if this helps make your screen visible.
Turn off hibernation mode. Hibernation files can occasionally become corrupt. Turning off this function and restarting your laptop could make your laptop display come back on.
Update your graphics driver. An out-of-date graphics driver may hinder the screen from displaying properly. You also could try updating the BIOS.
Here are a few things you could attempt to revive your Lenovo laptop if it has a black screen.
