Thunderbolt not charging via monitor or when monitor connected (HP Spectre x360 - 13-aw0XXXXX)

[bshack]

I have a Spectre X360 and a Samsung CJ791 34 inch monitor which can provide 85W via Thunderbolt 3 to charge an attached laptop. Unfortunately, I have only been able to get the monitor to charge the laptop a handful of times after several hard resets (holding power button for over 15 seconds) and uninstalling USB driviers / battery drivers.

Currently the laptop battery drains when connected only to the monitor via Thunderbolt 3 even though the orange charging light is illuminated. I get repeated "plugged in, but not charging" messages. Even worse, the laptop battery continues to drain (not charge) when I connect the HP charging cable to the second Thunderbolt 3 port. The laptop battery will only charge if I disconnect the external monitor, which then becomes a very expensive paper weight.

I saw another post that suggested a recent upgrade to the latest BIOS (F.26) may be a contributing factor, but I don't think that is the main issue because I *have* been able to get the monitor to charge the laptop on occasion both before and after the BIOS update. I cannot find more current Thunderbolt, battery, or AC adapter drivers than what I have installed. Any help would be appreciated.

Thanks!

Hi@bshack, Welcome to the HP Support Community.Apologies for all the inconvenience. Request you to follow the below troubleshooting steps

I have a few steps listed below that should help you resolve this concern: 

Unplug the charge and use the laptop until the battery drains to 15%. 

Turn off the laptop and turn it back on after 30mins. 

Reinstalled Microsoft ACPI-Compliant Control Method Battery under device manager: 

1) In the search box, type and open “Device Manager”.  

2) Expand “Batteries”.  

3) Right-click the "Microsoft ACPI-Compliant Control Method Battery" that is listed there.  

4) Click on “Uninstall”.  

5) At the prompt put a check in the box to remove the current driver  

6) Shutdown the computer.  

7) Remove the battery for minute and then put it back in.  

😎 When the computer comes back up it should automatically find the driver.  

9) Go to Device Manager.  

10) Expand Batteries.  

11) Right-click the "Microsoft ACPI-Compliant Control Method Battery" that is listed there. 

12) Click "Search automatically for updated driver software"  

Do the same thing with Microsoft ACPI-Compliant Embedded Controller.  

Restart the computer and the issue should be fixed.

My issue has been resolved for the time being. Shutting down windows, unplugging all cables, doing a hard reset, then starting the laptop after reconnecting the monitor cable seems to have done the trick.

Thanks you,
