Having a Dell laptop with a black screen can be frustrating. Here are some troubleshooting tips to help you resolve this issue.
Identify Symptoms and Causes
Symptoms of a black screen on a Dell laptop can indicate several possible causes. One common issue is a power problem, such as a drained battery or a faulty AC adapter. Make sure to check the power strip, power cable, and AC adapter for any signs of damage or malfunction.
Another possible cause is a hardware issue, such as a faulty graphics card or a problem with the motherboard. In this case, it may be necessary to contact Dell technical support for further troubleshooting assistance.
It is also important to consider software-related causes. A corrupt operating system or incompatible drivers can result in a black screen. Try booting the laptop in safe mode by pressing the F8 key during startup to see if the issue persists.
Additionally, check for any USB devices, SD cards, or USB flash drives connected to the laptop. Sometimes, these devices can interfere with the booting process and cause a black screen. Disconnect them and try restarting the laptop.
Troubleshooting Steps and Fixes

Safe Mode Booting and External Display Checks
Safe Mode Booting: To troubleshoot a black screen issue on your Dell laptop, you can try booting it in Safe Mode. This will start the computer with only essential drivers and services, which can help identify and resolve any software conflicts. To boot in Safe Mode, follow these steps:
1. Turn off your Dell laptop.
2. Press the power button to turn it back on.
3. Repeatedly tap the F8 key before the Windows logo appears.
4. Select “Safe Mode” from the boot options menu.
5. Wait for Windows to load in Safe Mode.
External Display Checks: If your Dell laptop’s screen is still black, you can check if the issue is with the display itself. Try connecting an external monitor to your laptop to see if it displays anything. Follow these steps:
1. Connect an external monitor to your laptop’s HDMI or VGA port.
2. Turn on the external monitor and make sure it is set to the correct input.
3. Press the Windows key + P on your keyboard to open the display settings.
4. Select “Duplicate” or “Extend” to display your laptop’s screen on the external monitor.
5. Check if the external monitor shows any display.
If the external monitor works fine, the issue may be with your laptop’s LCD screen or graphics card. If you still see a black screen on both the laptop and external monitor, it could be a hardware problem that requires technical support.
Updating Drivers and BIOS

3. Look for the “Drivers & Downloads” section.
4. Download the latest drivers for your laptop’s graphics card, chipset, and display.

6. After updating the drivers, check if the black screen issue is resolved. If not, proceed to update the BIOS.
7. In the “Drivers & Downloads” section, search for the latest BIOS update for your laptop model.
8. Download the BIOS update file.
9. Make sure your laptop is connected to a power source and the battery is charged.
10. Run the BIOS update file and follow the prompts to install the update.
11. Once the update is complete, restart your laptop and check if the black screen issue is resolved.
Updating the drivers and BIOS can often resolve black screen problems on Dell laptops. Make sure to follow the instructions carefully and seek further assistance from Dell support if needed.

F.A.Qs
Why is my computer turning on but the screen is black?
If your computer is turning on but the screen is black, it could be due to a loose connection or a malfunctioning component such as the CPU, motherboard, RAM, power supply, or graphics card. To troubleshoot, try reseating these components and test them in another computer to ensure they’re functioning correctly.
