Hi @Whitetail23,

Welcome to HP Support Community.

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

It sounds like your HP Pavilion is experiencing a hardware or power issue. Here are some troubleshooting steps you can try to diagnose and potentially fix the problem.

Check the Power Supply

• Power Adapter: Ensure the power adapter is working correctly. If you have a multimeter, you can test the adapter to see if it’s delivering the correct voltage. Alternatively, try using a different compatible power adapter.
• Power Outlet: Verify the power outlet is functional by plugging another device into it.

Perform a Hard Reset

A hard reset can help if there is an issue with the laptop’s hardware state.

1. Unplug the power adapter.
2. Remove the battery (if it is removable).
3. Press and hold the power button for at least 15 seconds.
4. Reinsert the battery (if removed) and plug the power adapter back in.
5. Try to turn on the laptop.

Check for Loose Connections

• Open the laptop (if you’re comfortable doing so) and check if there are any loose connections, especially around the battery, RAM, and power components.

Test the Battery

• Remove the battery and try powering the laptop directly from the power adapter. If it turns on, the battery might be faulty.
• Replace the battery with a new one (if available) to see if the battery is the issue.

Remove Peripherals

• Disconnect all external devices (USB drives, external monitors, etc.) and try to power on the laptop. Sometimes, external devices can cause startup issues.

Check for Physical Damage

• Inspect the laptop for any signs of physical damage that might have occurred while you were away. This includes checking the screen, keyboard, and ports.

Listen for Beeps or Sounds

• If the laptop is making any beeping sounds or showing LED blink codes, note these as they can help diagnose the issue.

Inspect the Display

• Sometimes the laptop might be on, but the display is not working. Try connecting an external monitor to see if there is a display output.

CMOS Battery

• If you're comfortable opening your laptop, you might want to check the CMOS battery. A dead or dying CMOS battery can sometimes prevent the laptop from starting.

I hope this helps.

Take care and have a good day.
