Fix Procedures:

  1. Check Power Status:

    • Verify that the power indicator lights are illuminated.

    • Connect the laptop to its charger and confirm the charging light is on.

  2. Adjust Screen Brightness:

    • Use the function keys (e.g., Fn + F keys) to increase the screen brightness.

    • Confirm that the display hasn't been dimmed to the lowest setting.

  3. Test with an External Monitor:

    • Connect an external monitor to your laptop using HDMI, VGA, or DisplayPort.

    • Switch the display output by pressing the appropriate function keys (e.g., Fn + F4 or Fn + F8).

    • Check if the external monitor displays your desktop.

      If your system is running slowly after these checks, visit our Slow Computer and Performance Optimization page.

  4. Cycle Display Modes:

    • Press Windows Key + P to open display settings.

    • Toggle between "Duplicate," "Extend," and "Second screen only" modes.

  5. Perform a Hard Reset:

    • Power off the laptop completely.

    • Disconnect the charger and remove the battery (if removable).

    • Hold down the power button for 15 seconds.

    • Reconnect the battery and charger, then power on the laptop.

  6. Inspect for Physical Damage:

    • Examine the laptop screen for cracks or signs of impact.

    • Check the hinges for any misalignment or damage.

  7. Check Display Cable Connections:

    • If comfortable opening the laptop:

      • Power off and unplug the laptop.

      • Carefully remove the bezel and access the display cables.

      • Ensure the ribbon cables are securely connected to both the motherboard and the screen.

  8. Reset RAM Modules:

    • Power off the laptop and remove the battery.

    • Open the RAM compartment.

    • Gently remove the RAM sticks and reseat them firmly.

  9. Boot in Safe Mode:

    • Restart the laptop and press F8 or Shift + F8 during boot-up.

    • Select "Safe Mode" and see if the display works.

  10. Update Graphics Drivers:

    • If display works on external monitor or in Safe Mode:

      • Download the latest graphics drivers from the manufacturer's website.

      • Install the drivers and restart the laptop.

  11. Check BIOS/UEFI Settings:

    • Restart the laptop and press F2, F10, or DEL to enter BIOS/UEFI.

    • Ensure that the internal display is enabled.

    • Save and exit.

  12. Run Built-in Diagnostics:

    • Access the laptop's diagnostics tool (often accessed by pressing F12 or a dedicated key during startup).

    • Run a full system test to check for hardware issues.

      If you suspect system software or update issues, our Windows Updates and Operating System Errors page could help.

  13. Test with One RAM Stick:

    • If you have multiple RAM modules, try booting with one at a time.

  14. Try a Different External Monitor or Cable:

    • Use another monitor and cable to rule out faults with peripherals.

  15. Consider Screen Replacement:

    • If the screen remains black after all steps, it may need to be replaced.
