Blank screen , HP pavilion x360

[rowanlo2]

I have an HP Pavilion laptop that I've been using lightly for the past three years. Today, while watching lectures, it suddenly turned off. I thought it might be a charging issue, so I plugged it in, but now it turns on, and the screen is just black.

Any suggestions on what to do?

After the above  troubleshooting steps if the unit  turns on 
 

here are some troubleshooting steps you can try:
 

1. Hard Reset the Laptop

• Disconnect the power adapter and remove the battery (if removable).
• Press and hold the power button for about 15 seconds.
• Reconnect the battery and power adapter, then try turning on the laptop again.

2. Check Display Brightness

• Make sure the screen brightness isn’t turned down all the way. Try increasing the brightness using the function keys (usually Fn + F3/F4) to see if that helps.

3. Try External Display

• Connect your laptop to an external monitor or TV using an HDMI or VGA cable. If the external display works, the issue may be with your laptop's screen or display settings.

4. Boot into Safe Mode

• Try booting into Safe Mode to see if the issue is related to a software problem:
  • Turn off the laptop.
  • Turn it on and immediately start pressing the F8 key repeatedly until the Advanced Boot Options menu appears.
  • Select Safe Mode and see if the display works.

5. Reset the BIOS

• Turn off your laptop.
• Turn it back on and repeatedly press the F10 key to enter the BIOS setup.
• If you can see the BIOS screen, try resetting to default settings (look for an option to load defaults).
• Exit and save changes.

6. Check RAM and Hard Drive Connections

• If you're comfortable opening the laptop, check if the RAM and hard drive are properly seated in their slots. Loose connections can sometimes cause boot issues.

7. Perform System Recovery

• If the above steps don’t work, consider using a recovery option:
  • If you have a recovery USB or recovery partition, try booting from it to restore the system.
