Continuous white light blinking on battery led. Even after switching off the system

[Emeka3]

My pavilion 15-cs0053cl right from the first moment I put it on keeps blinking on the battery led. With or without being pluged. It keeps blinking even after the system has been turned off. Is this a fault so I can go return it first thing tomorrow morning. Or how can I repair this?

@Emeka3,

Thank you for posting your query on HP Community,

I recommend you to perform the following steps to isolate the issue and arrive at a fix: 

• Power off the laptop.
• Remove the battery out. If the battery is integrated and does not have a latch to release it then leave the battery inside the laptop.
• Disconnected AC adapter from the laptop.
• Press and hold the power button for 15 seconds.
• Reconnect the battery and plug the AC adapter.
• Power ON the laptop.

Let us uninstall the battery drivers and then reinstall then. The following steps will help:

• Open the device manager. 
• Expand "Batteries". Right click on the ACPI drivers and select uninstall. 

• Close the device manager.
• Restart the laptop. While restarting, Windows will reinstall the battery drivers. 

If the battery still does not charge then please perform a BIOS update on the laptop via this link. Please ensure that the charger is connected to the laptop during the BIOS update. 

Once the BIOS update successful, you may test the battery if the battery does not charge. The following steps will help:

• Make sure the power cord and adapter is connected to the system and wall outlet.

• Press and hold the power button until the computer turns off completely.

• Turn on the computer.

• Immediately press the F2 key repeatedly, about once every second, until the UEFI Hardware Diagnostics screen is displayed.

• In the UEFI Main menu, select Component Tests.
