I recently reset the computer and it may have shut off before finishing. I moved to another town and when I tried to boot the computer I get two messages : (1) OSD Menu Lockout, (2) PC mode,PC going to sleep. When I turn it on the screen is black.

Hi @8432,

Welcome to HP Support Community.

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

It sounds like your computer might be encountering a boot issue due to an incomplete reset or a hardware/software conflict. Here’s a step-by-step guide to troubleshoot and potentially resolve these issues:

1. Power Cycle the Computer

Turn Off the Computer:

• Press and hold the power button until the computer completely shuts down.

Disconnect Power:

• Unplug the power cord from the computer. If it's a laptop, also remove the battery if it's removable.

Wait and Reconnect:

• Wait for about 30 seconds to a minute. Reconnect the power cord and, if applicable, reinsert the battery.

Turn On the Computer:

• Press the power button to turn the computer back on.

2. Check for External Peripherals

Disconnect All External Devices:

• Remove all connected peripherals (USB drives, external hard drives, printers, etc.).

Try Booting Again:

• Power on the computer with only the essential components connected (monitor, keyboard, mouse).

3. Check Display and Monitor

Ensure Monitor Connection:

• Verify that the monitor is properly connected to the computer and powered on.

Check Display Input Source:

• Make sure the monitor is set to the correct input source (HDMI, VGA, etc.).

Try a Different Monitor/Cable:

• If possible, connect to a different monitor or use a different cable to rule out display issues.

4. Access BIOS/UEFI Settings

Turn On and Enter BIOS/UEFI:

• Restart the computer and immediately press the BIOS access key (usually F2, F10, F12, Esc, or Del) as soon as you see the initial startup screen.

Check Boot Order:

• Ensure that the hard drive or SSD where your operating system is installed is set as the primary boot device.

Reset BIOS Settings:

• If you can access BIOS/UEFI, look for an option to Reset to Default Settings or Load Optimal Defaults. Save the changes and exit.

5. Perform a Hard Reset

Turn Off the Computer:

• Power off the computer completely.

Power On and Immediately Press Safe Mode Key:

• As you power on the computer, repeatedly press the F8, Shift + F8, or Shift key to try and enter Safe Mode.

I hope this helps.

Take care and have a good day.
