Hi @Masterblaster61,

 

Welcome to HP Support Community.

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

 

If your computer screen isn't coming on but the side indicator light (with the three discs) is blinking, it generally indicates that the computer is powered on but there's an issue with the display or related components. Here’s a step-by-step approach to troubleshoot this issue:

1. Check Power and Connections

Verify Power Connection:

  • Ensure that the computer is properly connected to a power source.
  • If using a laptop, check that the power adapter is securely plugged into both the laptop and the wall outlet.

Inspect Display Brightness:

  • Make sure the display brightness is not turned all the way down. Use the brightness function keys on your keyboard (often marked with sun icons) to increase brightness.

Check Display Cable:

  • If you’re using a desktop with an external monitor, ensure the monitor’s cable is securely connected to both the monitor and the computer.

2. Perform a Hard Reset

For Laptops:

  • Power Off: Shut down the laptop completely.
  • Unplug and Remove Battery: Disconnect the power adapter and, if possible, remove the battery.
  • Hold Power Button: Press and hold the power button for 15-30 seconds to drain any residual power.
  • Reconnect and Restart: Reinsert the battery (if removed), plug in the power adapter, and turn on the laptop.

For Desktops:

  • Power Off: Shut down the computer.
  • Unplug Power Cable: Disconnect the power cable from the back of the computer.
  • Hold Power Button: Press and hold the power button for 15-30 seconds to clear residual power.
  • Reconnect and Restart: Plug the power cable back in and turn on the computer.

3. Check External Monitor

Test External Display:

  • If you’re using a laptop, connect it to an external monitor or TV to check if the display issue is with the laptop screen or the graphics card.
  • Switch to the external display mode (usually by pressing Fn + F4, F5, F7, or a similar function key, depending on your laptop model).

Check Monitor Connections:

  • For desktops, ensure the monitor is powered on and properly connected to the computer.
  • Try a different cable or port if available.

4. Inspect for Hardware Issues

Check for Loose Components:

  • Laptops: If you’re comfortable opening the laptop, check for loose or disconnected internal cables, especially those connecting the display to the motherboard.
  • Desktops: Open the case and ensure that all internal components, such as RAM and graphics cards, are properly seated.

Listen for Beeps:

  • Pay attention to any beeping sounds from the computer, which may indicate specific hardware issues. Refer to the computer’s manual for beep codes.

5. Check BIOS/UEFI

  1. Access BIOS/UEFI:
    • For some issues, you may need to access the BIOS/UEFI settings. Restart the computer and repeatedly press the BIOS key (usually F2, F10, Del, or Esc) to enter the BIOS/UEFI setup.
    • If the screen remains blank, this step may not be possible.

 

I hope this helps.

 

Take care and have a good day.
