My hp chromebase 21.5" All-in-One, when I start up the system, the power light turns on but the screen is just black. I can't do anything with it.

Hi @yellowjersey,

Welcome to the HP Support Community. 

I'd be happy to help you! 

If your HP Chromebase 21.5" All-in-One powers on but the screen remains black, you can try the following troubleshooting steps:

Basic Troubleshooting Steps

Restart the Device:

• Press and hold the power button for about 10 seconds to force a shutdown.
• Wait a few seconds, then press the power button again to turn it back on.

Check the Power Supply:

• Ensure that the power cord is securely connected to both the Chromebase and the power outlet.
• Try a different power outlet if possible.

Check for Display Issues:

• Adjust the brightness using the keyboard shortcuts (usually the brightness keys are found in the function row, e.g., F6 and F7).
• Connect an external monitor via HDMI to check if the display works externally. This can help determine if the issue is with the internal screen.

Advanced Troubleshooting Steps

Perform a Hard Reset:

• Disconnect the power adapter.
• Press and hold the power button for at least 20 seconds.
• Release the power button, reconnect the power adapter, and turn on the device.

Enter Recovery Mode:

• Turn off the Chromebase.
• Press and hold the Esc + Refresh keys, then press the Power button.
• Release the Power button when the device turns on, but continue holding Esc + Refresh until you see a recovery screen.

Check for Hardware Issues:

• If the above steps don't work, there may be a hardware issue with the display or other internal components. In this case, it's best to contact HP support for further assistance or to arrange a repair.

If none of the above steps resolve the issue, you might need repair. Contact HP phone support for assistance:

There are no function keys on the Chromebase keyboard to try what you suggested. Additionally, the monitor is hardwired/secured to the base, so there is no option to try a different monitor.

So I am unable to try your suggestions.
