Welcome to The HP Support Community.  

Thank you for posting your query, I will be glad to help you.

I understand you are facing an issue with vertical lines on a laptop screen can be caused by various issues, ranging from software problems to hardware failures.

Please try the following Troubleshoots steps.

2.    Disconnect the AC adapter.

3.    Remove any discs from the disc drive.

4.    Remove memory cards from the card reader slot.

5.    Disconnect all nonessential peripheral devices, such as printers, scanners, external hard drives, and USB flash drives.

6.    Disconnect the AC adapter press and hold the power button for approximately 15 seconds.

7.    Reconnect the AC adapter, and then turn on the computer.

Step 2

Turn off the unit and please press and hold the Windows key + letter B key and the power button together for 30 seconds after 30 seconds, 1st release the power button but keep holding the Windows key and B key for ten more seconds and then release these two keys If done correctly, you will see the display flashing once.

Step 1: Restart Your Laptop

• Sometimes, a simple restart can resolve temporary glitches. Restart your laptop to see if the lines disappear.

Step 2: Check Display Connections

• Ensure the display cable is properly connected. If you're comfortable, you can open your laptop and check the connections between the display and the motherboard. This step might be best left to a professional if you're not experienced with laptop hardware.

Step 3: Update Graphics Drivers

• Outdated or corrupted graphics drivers can cause display issues. Update your graphics drivers:
  1. Press Win + X and select Device Manager.
  2. Expand the Display adapters section.
  3. Right-click your graphics card and select Update driver.
  4. Choose Search automatically for drivers and follow the prompts.

Step 4: Boot into Safe Mode

• Booting into Safe Mode can help determine if the issue is software-related.
  1. Press Win + R, type msconfig, and press Enter.
  2. Go to the Boot tab and check Safe boot, then select Minimal.
  3. Restart your laptop.
• If the lines are not present in Safe Mode, it suggests a software or driver issue. Update or reinstall your graphics drivers as mentioned above.

Step 5: External Display Test

• Connect your laptop to an external monitor or TV using an HDMI or VGA cable.
  • If the external display shows the same lines, the issue is likely with your graphics card or drivers.
  • If the external display is fine, the problem is likely with your laptop's screen or its connections.

Step 6: Run Display Diagnostics

• HP laptops often have built-in diagnostics:
  1. Turn off your laptop.
  2. Turn it on and immediately press Esc repeatedly until the Startup Menu opens.
  3. Press F2 to open the HP PC Hardware Diagnostics.
  4. Run the Display Test.

Step 7: Check for Physical Damage

• Inspect the screen for any physical damage. Cracks or pressure marks can cause lines. If the screen is damaged, it will need to be replaced.
