Hi @RajaJanak,

Welcome to the HP Support Community.
 

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

If your HP laptop screen goes blank or dark after booting up, it can be due to several reasons. Here are some troubleshooting steps to help identify and resolve the issue:
 

Check the Connections:
 

• Ensure that the power cord is connected properly.
   
• Verify that the laptop is actually powered on and not in sleep or standby mode by checking the power indicator light.

External Display Test:
 

• Connect your laptop to an external monitor using an HDMI or VGA cable. This can help determine if the issue is with the laptop's display or the internal hardware.
   
• If the external monitor displays correctly, the problem might be with the laptop's screen or its connections.

Safe Mode Boot:
 

• Try booting the laptop in Safe Mode. This can be done by restarting the laptop and pressing the F8 key repeatedly while it’s starting up. In Safe Mode, you can check if a driver issue is causing the screen to remain blank.

Check Display Settings:
 

• Once in Safe Mode, right-click on the Desktop and select Display Settings. Ensure that the display output is set correctly, especially if you have previously used multiple monitors.

Reset the Laptop:
 

• Perform a hard reset. Turn off the laptop, remove the battery (if removable), disconnect the AC adapter, and then hold the power button for about 15 seconds. Reconnect the power source and try turning on the laptop again.

Update or Rollback Drivers:
 

• In Safe Mode, access Device Manager by right-clicking on the Start menu and selecting it. Check the Display Adapters section and update or rollback drivers if necessary.

BIOS or Hardware Check:
 

• Access the BIOS settings during startup (usually by pressing the F2, F10, or ESC key) to ensure that the hardware is recognized properly. If a BIOS update is needed, follow HP’s official instructions carefully.
  
  
  I hope this helps.

Take care and have an amazing day!
