Experiencing a black screen on your HP computer can be frustrating. This guide will help you troubleshoot and resolve the issue.

Inledande felsökningssteg

Kontrollera strömförsörjningen

Ensure your computer is receiving power. Check the power cord and the power outlet. If you’re using a laptop, make sure the battery is charged or try using the AC adapter.

Starta om datorn

A simple restart can often resolve the issue. Hold down the power button for about 10 seconds to force a shutdown. Wait a few seconds, then turn your computer back on.

Hardware-Related Solutions

Inspect the Display

Connect your HP computer to an external monitor using an HDMI or VGA cable. If the external display works, the issue might be with your laptop’s screen or its internal connections.

Reseat RAM and Hard Drive

Loose RAM or a hard drive can cause a black screen. Turn off your computer, unplug it, and remove the battery if possible. Open the back panel, and carefully reseat the RAM and hard drive.

Software-Related Solutions

Starta i felsäkert läge

Booting in Safe Mode can help determine if the problem is software-related.

  1. Turn off your computer.
  2. Turn it on and repeatedly press the F8 key until the Advanced Boot Options menu appears.
  3. Välj "Säkert läge" och tryck på Enter.

If your computer boots successfully in Safe Mode, the issue might be due to a recently installed program or driver.

Uppdatera eller rulla tillbaka grafikdrivrutiner

Graphics driver issues can also cause a black screen.

  1. Starta i felsäkert läge.
  2. Go to Device Manager.
  3. Find “Display adapters,” right-click your graphics driver, and choose “Update driver” or “Rollback driver.”

  4. Press and hold the power button for 15 seconds.
  5. Reconnect the power cord and turn your computer back on.

If the black screen issue started recently, performing a system restore might help.

  1. Starta i felsäkert läge.
  2. Open Control Panel and go to “System and Security” > “System” > “System Protection.”
