Charging Light blinking White

[Plakman]

I change a battery on my laptop few days before. Now when the laptop is turned off the charging light blinking 3 times every 5 seconds. What this could mean?

I perform a full battery check and optimization from UEFI HP assistant but nothing happens!

Hi @Plakman,

Welcome to HP Support Community.

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

The blinking charging light pattern on your HP Laptop - 15s-eq1012nv is often indicative of an error related to the battery or power system. Since you recently replaced the battery, the issue may involve the battery itself, the connection, or the charging circuitry. Here's what the blinking light typically signifies and what you can do to resolve it:

Possible Causes

1. Battery Error: The replacement battery might not be compatible, faulty, or not recognized by the system.
2. Power Connection Issue: The battery might not be seated correctly in its compartment, or the power adapter might not be supplying sufficient power.
3. BIOS or Firmware Mismatch: The system may need a BIOS or firmware update to recognize the new battery.
4. Charging Circuit Fault: A hardware issue with the motherboard's power delivery system.

Troubleshooting Steps

1. Reset the Laptop's Power

• Disconnect the power adapter and remove the battery.
• Press and hold the power button for 15–20 seconds to drain any residual power.
• Reinstall the battery and connect the power adapter.
• Turn the laptop back on and observe the behavior of the charging light.

2. Inspect the Battery and Connections

• Ensure the battery is securely seated in its compartment.
• Check for any visible damage or dirt on the battery connectors or laptop terminals.

3. Verify Battery Compatibility

• Confirm that the new battery is an official HP replacement or meets the exact specifications of your original battery.
• If possible, test with another battery to rule out compatibility issues.

4. Update BIOS and Drivers

• Update the BIOS for your PC by clicking on the link.

Make sure you keep only the charger plugged in while updating the BIOS for your PC.

Click on the + sign next to BIOS and then download the file.

Open the file and follow the on-screen instructions to complete the update.

• Please install all the pending updates for the Windows operating system following the below steps.

go to Start > Settings > Update & Security > Windows Update and select Check for updates. If the upgrade is 

• Install the updates, reboot the system, and check if the issue persists.

5. Perform a Battery Calibration

• Charge the battery to 100%.
• Use the laptop until the battery is completely drained and shuts off.
• Recharge it to 100% without interruption.
• This helps recalibrate the battery and the laptop's battery management system.

6. Check Power Adapter Functionality

• Ensure the power adapter is functioning correctly. Try a different compatible adapter if available.

7. Hardware Diagnostics

• Run HP's UEFI Diagnostics tool:
  1. Power off the laptop.
  2. Turn it on and press Esc repeatedly until the Startup Menu appears.
  3. Press F2 to access System Diagnostics.
  4. Run the battery test and power test.

Please mark this post as “Accepted Solution” if the issue is resolved and if you feel this reply was helpful click “Yes”.

I hope this helps.

Take care and have a good day.

Dear @Irwin6,

Thank you for your response!

The battery is a compatible battery and meet's the requirements of the system. Also I've perform battery calibration and system Diagnostics. All of the test are positive results. I had already perform BIOS update throu HP diagnostic tool. Also all the Windows update are installed.

The battery charged to100% when needs and the duration is very satisfactory.

At last I would like to tell you that all the connections are good.

I mention there that when the light is blinking the laptop doesn't turning on. It needs to press the button continuously for 10 sec so I can turn it on.

Thank you in advance!
