Hi @Bhar4,

 

Welcome to HP Support Community.

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

 

It sounds like your HP laptop is experiencing a hardware or software issue that's preventing the display from working and causing the keyboard and touchpad to be unresponsive. Here are some troubleshooting steps you can try:

Basic Troubleshooting Steps

Restart the Laptop:

  • Hold down the power button for about 10 seconds to force a shutdown.
  • Wait a few seconds, then press the power button again to restart the laptop.

Check External Display:

  • If possible, connect your laptop to an external monitor to see if the display works there.
  • This can help determine if the issue is with the laptop's screen.

Advanced Troubleshooting Steps

Perform a Hard Reset:

  • Turn off the laptop and disconnect all external devices (e.g., USB drives, external mice, etc.).
  • Disconnect the power adapter and remove the battery (if removable).
  • Press and hold the power button for 15-20 seconds.
  • Reconnect the power adapter and battery, then try to turn on the laptop.

Boot into Safe Mode:

  • If you can see the HP logo or any screen during startup, repeatedly press the F8 key to try and boot into Safe Mode.
  • In Safe Mode, you can troubleshoot driver issues that might be causing the problem.

Check BIOS Settings:

  • Turn off the laptop and then press the power button. Immediately start pressing the F10 key repeatedly to enter the BIOS setup.
  • In the BIOS, check if the keyboard and touchpad are recognized.
  • Exit the BIOS and restart the laptop.

Reset BIOS to Default Settings:

  • While in the BIOS, look for an option to reset settings to default.
  • Save the changes and exit.

Hardware Troubleshooting

Reseat the RAM:

  • If you're comfortable opening your laptop, try reseating the RAM modules.
  • Turn off the laptop, remove the battery and power adapter, open the laptop case, and carefully remove and reinsert the RAM modules.

Check for Loose Connections:

  • Ensure that there are no loose connections inside the laptop, particularly related to the display cable and keyboard connections.

I hope this helps.

 

Take care and have a good day.
