Hi @Fredsyear2020,

Welcome to HP Support Community.

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

If your laptop won’t turn off after replacing the battery and charger, and the power light remains on for a few seconds before turning off, it’s essential to systematically troubleshoot the problem. Here’s a step-by-step guide to help you diagnose and potentially resolve the issue:

1. Perform a Hard Reset

Disconnect All Power Sources:

• Unplug the laptop from the AC adapter.
• Remove the battery (if it’s removable).

Perform the Reset:

• Press and hold the Power button for 15-30 seconds. This will help discharge any residual power.

Reassemble and Test:

• Reinsert the battery and plug the laptop back into the AC adapter.
• Try turning on the laptop again.

2. Check the Power Supply and Battery

Verify Battery and Charger:

• Ensure that the new battery and charger are compatible with your laptop model.
• Confirm that the charger is providing the correct voltage and current as specified for your laptop.

Inspect Charger and Connections:

• Check for any visible damage to the charger or charging port.
• Ensure all connections are secure and free of debris.

3. Test with Only AC Power

Remove the Battery:

• Disconnect the battery and plug in the AC adapter.

Power On:

• Try turning on the laptop using only the AC power. If the laptop powers on successfully, the issue might be with the battery.

4. Check for Hardware Issues

Inspect Internal Components:

• If you’re comfortable with hardware, open the laptop to check if the internal components (such as RAM, hard drive, and connections) are properly seated and connected.

Test RAM and Storage:

• Remove and reseat the RAM modules. If you have multiple RAM sticks, try testing with one at a time.
• Check the connections for the hard drive or SSD.

5. Check for Error Lights or Beeps

Listen for Beep Codes:

• When you attempt to turn on the laptop, listen for any beep codes. These codes can help identify specific hardware issues.

Observe LED Indicators:

• Pay attention to any LED lights or indicators that might provide clues about the issue.

6. Update or Reinstall BIOS

Access BIOS/UEFI:

• If the laptop can be powered on, access the BIOS/UEFI settings (usually by pressing F2, Del, or Esc during startup).

Check for Firmware Updates:

• If possible, check for and apply any available BIOS updates.

I hope this helps.

Take care and have a good day.
