My laptop randomly shuts down

[shadowgarden]

My HP Pavilion Plus 14 7840u laptop randomly shuts down out of nowhere but only on battery, when charging it does not shutdown at all. I have tried almost everything, reinstalled windows, swapped out wifi card for a new one, put tape on the wifi card etc etc! When it shuts down the power button is unresponsive and I have to plug the power supply for a sec to get the power button working again to power it on. I am lost.

Hi @shadowgarden 

Welcome to HP Support Community.

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

It sounds like you're dealing with a frustrating issue. Here are some steps you can take to troubleshoot your HP Pavilion Plus 14 that shuts down randomly on battery:

1. Check Battery Health

• Use HP’s built-in battery diagnostic tool:
  1. Restart your laptop and press Esc repeatedly until the Startup Menu opens.
  2. Press F2 to enter the HP PC Hardware Diagnostics.
  3. Select Battery Test to check the health of your battery. If the battery is failing, it may need to be replaced.

2. Inspect Power Settings

• Go to Control Panel > Power Options.
• Check your power plan settings. Ensure that the settings for "Sleep" and "Hibernate" are set appropriately.
• Look for any advanced settings that might be causing the laptop to shut down.

3. Update BIOS

• Check for BIOS updates on the HP Support website. Sometimes, BIOS updates can resolve power management issues.

4. Perform a Hard Reset

1. Turn off the laptop and disconnect it from the power source.
2. Remove the battery (if removable).
3. Press and hold the power button for about 15 seconds.
4. Reinstall the battery, reconnect the power, and turn it on.

5. Check for Overheating

• Ensure the laptop’s vents are clean and unobstructed. Overheating can cause the laptop to shut down. You might also want to monitor temperatures using a tool like HWMonitor or Core Temp.

6. Inspect for Hardware Issues

• Since you swapped out the Wi-Fi card, check other internal components (like RAM) to ensure they are seated correctly.
• If you’re comfortable doing so, reseat the RAM modules and check connections.

7. Run Windows Power Troubleshooter

• Go to Settings > Update & Security > Troubleshoot > Additional troubleshooters > Power. Run the troubleshooter to see if it detects any issues.

8. Check Event Viewer

• Open Event Viewer by searching for it in the Start menu.
• Look for any critical errors or warnings around the time of the shutdown. This might give you clues about what’s causing the issue.

9. Replace the Battery

• If the battery health check indicates that the battery is in poor condition or if none of the above steps resolve the issue, consider replacing the battery.

I hope this helps.

Take care and have a good day.
