Battery charges for just a few seconds

[M4rw]

Since a few weeks my laptop doesn't charge anymore when powered on. No specific hardware/software changes were made around that time. When I connect the adapter, the indicator light turns white, the tray icon says the battery is charging for about 5 seconds, then says it's on battery power instead of net power. The indicator light stays white. When the laptop is turned off and the charger is plugged in, the indicator light is orange and the laptop charges normally.

I already tried some things:

• I've replaced the battery itself.
• I've used the HP Support Assistant to update all drivers.
• I've tried a hard reset following this guide: https://support.hp.com/us-en/document/c01684768#c01684768_nonremovablebatt
• I've updated the BIOS following this topic: https://h30434.www3.hp.com/t5/Gaming-Notebooks/My-HP-omen-15-laptop-battery-is-plugged-but-not-charg...
• I've removed the battery drivers following this topic: https://h30434.www3.hp.com/t5/Notebook-Hardware-and-Upgrade-Questions/Laptop-only-charges-when-turne...

The charging implies that the charger itself is still working (right?) so I'm not sure how to continue troubleshooting. Any help would be appreciated.

Hi! @M4rw, 

Try the steps recommended below.

Check the BIOS to confirm the setting is set to Full Charge, if it is not, change the BIOS setting to Full Charge.

Power on the unit.
Press F10 to enter the BIOS.
Select the Power option. 

Full Charge: The battery charge stops at 91~100%. 
Extended Life of Battery Pack: The battery charge stops at 76~80%. 
Optimize Life of Battery Pack: The battery charge stops at 46~50%. 

Save changes and exit the BIOS.

On your keyboard, press the Windows logo key and X at the same time to open the quick-access menu.

Click Device Manager.

In Batteries section, right-click on your battery driver, commonly it’s Microsoft  ACPI-Compliant Control Method Battery. Then click Uninstall device.

Restart the PC the drivers would automatically install again.

Run Power Troubleshooter.

On Cortana, enter  Troubleshooter then select Troubleshooting.
Click Improve power usage to open the window, then click Next. 
This should run the troubleshooter, and can fix any detected issues. You may try restarting your computer and charge your battery again.

Lastly, try running a battery test from the F2 system diagnostics page under the component test.

Thanks for you reply!

The BIOS setting was already at Full Charge. I changed it - save&exit, and changed it back just to be sure.

Removing the Microsoft ACPI-Compliant Control Method Battery didn't change anything either.

The Power Troubleshooter did fix some settings, but did not fix the charging issue.

The most useful came from the F2 diagnostics menu. I ran all power tests, and the adapter was the only one which did not pass and showed "Smart adapter feature failed to return valid data".

Hi! @M4rw,

Thanks for writing back to us.

It sounds like the AC adapter is faulty due to which you have charging issues.

I've replaced the adapter with HP part number 776620-001, and everything works as expected again. Thanks for the help!
