The problem with your Lenovo PC turning on but the screen remains black could be such a simple error that you could even fix it yourself. If you turn on your Lenovo laptop and feel that the computer is working, but the screen is black, don't panic. There may be a way to fix the black screen problem without having to replace it or replace the computer.
Why does my Lenovo laptop turn on but the screen stays black?
There are a number of reasons why your Lenovo PC screen won't turn on.
- Hardware errors: If hardware components or peripherals such as cables are worn, it can prevent the screen from being displayed.
- A defective display: if there is something wrong with the display, it may stop showing the image.
- A defective battery: If your laptop battery is very low or not working as it should, it could create problems with your display.
- Software errors: Windows and other software applications can also affect the screen display.
What to do if the Lenovo laptop turns on but the screen remains black
If your Lenovo computer screen isn't working, there are a few things you can try to get it working again. Try these steps, each in order, until you find the solution that works.
1. Restart your computer. It is amazing how a simple restart can solve any problem of any technological gadget. Restart the computer with no peripherals connected. If you fixed the problem, it is likely that a connected device prevented the screen from turning on properly.
2. Reset the view mode. Press the following key combination: Windows key + Ctrl + Shift + B. Press all keys at the same time and then release them immediately. This updates the display connection and could fix the black screen issue on your Lenovo laptop.
3. Remove all peripherals connected to your laptop. If the software or driver for one of these devices is damaged, the display may not work properly.
4. Try a soft reset. In this case, a soft reset is similar to turning the laptop on and off. Turn off your Lenovo laptop, unplug it from the power supply and remove the battery; unplug all peripherals and let everything rest for 30 seconds to one minute.
Then, hold the power button for 60 seconds, put the battery back in place and plug in the power cord. Then turn on the computer to see if the display turns on properly.
5. Connect to an external monitor. To test the LCD and LCD cables, connect your laptop to an external monitor with a VGA cable or connect it to a TV as an external display using an HDMI cable, depending on the connections available on your system. Then restart your computer and check if your Lenovo PC turns on but the screen still remains black.
When the computer restarts, it should be displayed on the external monitor or TV. If not, you may need to press F4 on your keyboard (or another key with a rectangular box with vertical lines to the left and right, to indicate the monitor).
6. Update the video drivers. If the video card drivers are damaged or out of date, the display may not work properly. Try updating the driver and then restarting your computer to see if the display turns on.
7. Update Windows. Another thing to try might be to update Windows. Windows updates can fix many problems on your computer. So if you are left behind you may have some kind of problem with your PC. Update your version of Windows to see if the display turns on.
8. Restart the explorer.exe process. Explorer.exe manages several essential processes on your computer, including the desktop, toolbar, and many other things. If something happened and that process was accidentally closed, the screen could go black. Try restarting it to see if that fixes the problem:
- Press Ctrl + Shift + Esc to open the Task Manager.
- Tap Details.
- Find and select explorer.exe, then click End Task.
- Restart your computer to see if the black screen problem on your Lenovo laptop is resolved.
9. Reset the computer to factory settings. This solution is a nuclear option because when you reset your computer, it will be back as it did when it left the factory and you will lose all your data, so try everything else first. If you need to use this option, make a backup of your data before you start restoring your Lenovo PC.
Know when to call a professional
If you've tried all of the above and your Lenovo laptop screen is still not working, there is likely a problem with the internal cables connecting the screen to your computer board or display. Unless you are experienced in computer repair, it may be time to call a professional. Remember, if your computer is still under warranty, contact Lenovo first.
