Solution 2: Connect to an External Monitor or TV
If the Dell laptop screen remains black after trying hard reset, connect it to an external monitor or TV using an HDMI cable.
If the display shows up on the external monitor, then the issue is likely with the laptop screen. But if both the laptop screen and external monitor remain black, then the problem is with the software or internal hardware.
How to connect to an external display:
Step 1: Turn off the Dell laptop and connect the HDMI cable from the laptop’s HDMI port to the TV/monitor.
Step 2: Turn on the external display first, then power on the Dell laptop.
Step 3: Try toggling between the laptop screen and the external display by pressing the Fn + F1 or F2 function keys.
This method also indicates whether the problem is specifically with the laptop’s display panel or components like the GPU, motherboard etc.
Solution 3: Boot Dell Laptop into Safe Mode
Booting into Safe Mode starts Windows with only the essential drivers and services. This can help identify if the issue is either software or driver-related causes of the black screen.
Follow these steps to boot your Dell laptop into Safe Mode:
Step 1: Force shut down the laptop by pressing and holding the Power button for 10-20 seconds.
Step 2: Turn on the laptop and immediately start pressing the F8 key continuously.
Step 3: This will bring up the Advanced Boot Options menu.
Step 4: Select Safe Mode and press Enter to boot into Safe Mode.
Step 5: Log in to your account. The screen resolution will be low, but you should now see the desktop.
Step 6: Restart the laptop normally and check if the black screen issue is resolved.
Safe Mode dismisses any third-party software conflicts or driver issues that are causing the black display on your laptop.
Solution 4: Run Hardware Diagnostics on the Dell Laptop
Dell laptops come with a pre-installed hardware diagnostics tool. This can test the various laptop components for faults like bad RAM, motherboard issues, GPU failure etc.
To run the ePSA Preboot System Assessment, follow the steps below:
Step 1:Turn off the Dell laptop.
Step 2: Press and hold the Fn key, then power on the laptop.
Step 3:This will initiate the hardware diagnostics.
Step 4: Run the full suite of tests. It will take some time.
Step 5: If any error is detected, it can indicate faulty RAM, storage drive, battery or motherboard failure.
You can also press F2 during boot to enter the BIOS settings menu. Navigate to the SupportAssist section and launch Hardware Diagnostics from there.
Solution 5: Check for Loose Screen Cable Connection
A loose display cable is a common reason for a Dell laptop’s screen remaining black. This DIY fix involves opening up the laptop to check the display cable connections.
To check the display cable connections:
Step 1: Turn off and unplug the power from the Dell laptop. Remove any removable batteries.
Step 2: Using a plastic pry tool, carefully pry open the bezel starting from the top or bottom edge.
Step 3: Once the bezel is removed, you’ll see the display panel and cables.
Step 4: Check that the thin display cables are firmly plugged into the connector at the bottom of the panel.
Step 5: Also check the other end where the cables connect to the motherboard behind the hinges.
Step 6: Reconnect any loose cables firmly and reassemble the laptop. Test if the black screen issue is fixed.
This simple cable reconnection fix can restore the display in many cases. Tightly plugging in the video cables eliminates the black screen due to cable issues.
Solution 6: Update or Reinstall Graphics Drivers
Outdated or corrupted graphics drivers can also result in a Dell laptop showing only a black screen.
You can update the display and GPU drivers to the latest available version:
Step 1: Boot into Safe Mode with Networking by selecting the option from Advanced Boot Options. This starts with Windows with internet access.
Step 2: Go to Device Manager > Display adapters. Right-click and Update the driver.
Step 3: Search automatically online for updated driver software. Install it and restart.
Step 4: Alternatively, go to the Dell support site and manually download the latest display driver for your specific Dell laptop model.
Step 5: Uninstall the existing driver first if updating doesn’t work. Then fresh, install the newly downloaded driver.
Updating to the newest graphics drivers often resolves black screen problems caused by incompatible or buggy drivers.
Solution 7: Restore or Reset Windows on Dell Laptop
If you recently installed apps or drivers before the black screen appeared, restoring Windows can fix software-related causes.
To restore Windows to an earlier restore point:
Step 1: Boot into Safe Mode. Press F8 during startup and select Safe Mode.
Step 2: Go to Search > type strut> Hit Enter.
Step 3: Open System Restore and choose a restore point created before the issue occurred.
Step 4: Follow the prompts to restore Windows, which will undo recent changes.
You can also reset Windows, which performs a clean reinstallation:
Step 1: In Safe Mode, go to Settings > Update & Security > Recovery.
Step 2: Choose Get Started under the Reset this PC option.
Step 3: Follow the prompts to reinstall Windows deleting apps and programs.
This will fix any operating system file errors causing black display issues.
Solution 8: Test with a Known Good Screen
If the above steps don’t help, the cause may be a faulty display panel itself. Testing with a known good replacement screen will confirm this.
Step 1: Order a replacement LCD screen that is compatible with your specific Dell laptop model.
Step 2: Follow a teardown guide to replace the current screen with the new replacement LCD.
Step 3: Reassemble the laptop and test if the new display works properly.
If the replacement screen shows the display, then the original screen was the faulty one. But if even the new screen doesn’t turn on, then there are deeper hardware issues with the motherboard or GPU.
Solution 9: Motherboard or Video Card Repair
If the black screen doesn’t get fixed on your Dell laptop after trying the above solutions, the main problem is with the motherboard or dedicated graphics card.
This requires professional repair service as fixing motherboard or GPU issues involves advanced micro-soldering and replacement of SMD components.
A computer repair tech can diagnose and replace any damaged parts on the motherboard or video card circuit to resolve hardware-based black screen problems.
Note: All these solutions are based on my personal experience and knowledge. If your laptop is fixed by following these solutions, that's great. However, these solutions may not work in all conditions. In that case, please contact DELL Support.
