Hi @Ibrahim372,

Welcome to HP Support Community.

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

If your computer isn’t displaying anything on the screen, it can be due to a variety of issues ranging from simple connection problems to more complex hardware failures. Here’s a step-by-step guide to troubleshoot the issue:

1. Check Power and Connections

Verify Power Supply:

• Ensure the computer is plugged into a working power source. Check the power cord and power adapter connections.

Inspect Display Connections:

• External Monitor (if applicable): If you're using an external monitor, ensure that the cable connecting the monitor to the computer is secure.
• Internal Display: For laptops, make sure the lid is fully opened and the display connections are secure. If you recently worked inside the laptop, check that the display cable is connected properly.

Power Indicators:

• Look for any power indicator lights on the computer. If the computer is on but the screen is blank, this might indicate a display or connection issue.

2. Perform a Hard Reset

Power Off the Computer:

• Hold down the power button for about 10-15 seconds until the computer completely shuts off.

Disconnect Power:

• Unplug the power adapter (and remove the battery if it’s a removable type).

Drain Residual Power:

• Press and hold the power button for another 15-20 seconds to discharge any residual power.

Reconnect and Power On:

• Plug the power adapter back in (and reinsert the battery if removed) and press the power button to turn on the computer.

3. Check Display Brightness and Functionality

Adjust Brightness:

• For laptops, adjust the screen brightness using the function keys (usually marked with a sun icon).

External Monitor Test:

• Connect your laptop to an external monitor or TV to see if it displays correctly. If it does, the issue may be with the laptop’s internal display or its connection.

I hope this helps.

Take care and have a good day.
