Hi @920Harsh,

Welcome to the HP Support Community.
 

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

I understand your HP laptop screen is flickering on and off, and you're unable to run system diagnostics. It could be due to a hardware issuedriver conflict, or even a loose display connection. Here's a step-by-step guide to help you troubleshoot:

Immediate Steps to Try:

  1. Hard Reset the Laptop:
    • Turn off the laptop.
    • Unplug the power adapter and remove any external devices.
    • Press and hold the power button for 15 seconds.
    • Plug the power back in and turn it on.
       
  2. Boot into Safe Mode:
    • If the screen stays on long enough:
      • Hold Shift and click Restart from the Start menu.
      • Go to Troubleshoot > Advanced options > Startup Settings > Restart.
      • Press 4 to boot into Safe Mode.
    • If the flickering stops in Safe Mode, it's likely a driver or software issue.
       
  3. Connect to an External Monitor:
    • Use HDMI or USB-C to connect to another display.
    • If the external monitor works fine, the issue may be with your laptop screen or cable.
       
  4. Try HP Hardware Diagnostics via USB: If you can’t run diagnostics from the laptop:
    • Use another computer to download the HP PC Hardware Diagnostics UEFI tool: Download from HP
    • Create a bootable USB and run diagnostics from there.


 If You Can Boot into Windows:

  • Update Graphics Drivers:
    • Go to Device Manager > Display adapters.
    • Right-click your graphics driver and choose Update driver.
    • Or visit HP Support to download the latest drivers.
       
  • Disable Hardware Acceleration:
    • In apps like Chrome or Office, go to settings and disable hardware acceleration to see if it helps.

 

I hope this helps.

 

Take care and have a good day.
