HP all in one desktop monitor

[Harborcon]

HP all in one desktop, purchased 2016,  running Windows 10.  Computer will not boot. Powers on with HP logo for a split second, then instantly powers off. No recent software or driver changes. LAN connection. Connected to HP OfficeJet 3830 printer. I’ve disconnected and reconnected power source after 30 seconds; Herod down power button for 20 seconds…no change.

Hi @Harborcon,

Welcome to HP Support Community.

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

It sounds like your HP all-in-one desktop is experiencing a power or hardware issue. Here are a few troubleshooting steps you can try.

Check Power Supply: Ensure that the power cable is securely connected to both the desktop and the power outlet. If possible, try using a different power cable or outlet.

Inspect for Loose Components: Open the desktop (if possible) and check for any loose or disconnected components, like RAM or hard drive connections.

Perform a Hard Reset:

• Disconnect all external devices (USB drives, printers, etc.).
• Hold down the power button for about 20 seconds to discharge any residual power.
• Reconnect the power cable and try turning it on again.

Test with Minimal Hardware:

• Remove any additional hardware (e.g., extra RAM, peripheral devices) and try booting with just the essential components.

Listen for Beep Codes: If your desktop has internal speaker beeps, listen for any beep codes during the power-on sequence. These codes can indicate specific hardware issues.

Check for LED Indicators: Look for any LED indicators on the desktop. Some models have diagnostic LEDs that can help identify issues.

Try an External Monitor: If you have an external monitor, connect it to the desktop to see if the issue is related to the built-in display.

CMOS Battery: Sometimes, a failing CMOS battery can cause boot issues. Try replacing the CMOS battery (a coin-cell battery on the motherboard).

I hope this helps.

Take care and have a good day.
