Battery Will not fully charge, stops at 73% even after replacing battery

[Lightwave22]

Please help, I cannot get my battery to fully charge no matter what I do.  The battery in the Envy x360 m6 stops charging at "73% available, plugged in".  Here are the things I've tried, in order:

• Run the HP support assistant battery check - pass
• Run the battery test from boot-up diagnostics - pass
• Update firmware and all drivers to current version
• Replace the battery with a new HP oem battery (still at same 73% with new battery)
• Run both the support assistant and diagnostics battery tests again, with and without the charger connected (both pass)
• Follow the HP battery calibration instructions to drain the battery entirely and recharge
• Remove the Win10 AICP battery driver, video driver, power off and remove the battery, remove the cmos battery, hold the power button for 30 seconds, replace both batteries, then fully drain and recharge the battery again before booting windows and reinstalling drivers
• Remove the AICP charger driver and reinstall

I've read just about every forum post I can find on this subject, but I just can't seem to find a way to convince the battery to charge.   I did see one post about resetting the charge bit, but it wasn't clear to me from that post how to accomplish this (besides the steps I listed above).  I appreciate any help

Hi@Lightwave22, Welcome to the HP Support Community!

I understand that you have an HP ENVY Notebook and the battery charges till 73% and then stops. You've done a remarkable job performing the steps. 

Did any software changes or updates happen on your laptop after which the battery stopped charging at 73%?

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

NOTE: You may skip any steps that have been performed by you already.

• 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.

Now let us uninstall the battery drivers and reinstall them. The following steps will help:

• Open the device manager. 
• Expand "Batteries". Right click on the ACPI battery drivers and select uninstall. If there are multiple entries of the ACPI battery drivers then uninstall them all.
• Close the device manager.Restart the laptop.
• The Windows operating system will reinstall the battery drivers while restarting. 

It is a good idea to download and run a BIOS update for your laptop via this link. The charger must be connected until the BIOS update is complete to avoid any power interruptions due to battery draining out. 

Post a successful BIOS update,  you may check if the battery charges fully. If not then please perform the steps as described in detail in this HP document. These steps help in testing and calibrating the battery. 

NOTE: Please skip the steps mentioned in "Test and calibrate the battery using HP Support Assistant".

I sincerely hope this fixes the issue. Keep me posted. 

Hope this helps! Keep me posted.

Thanks for your reply Praveenbv,  There were no software changes to my laptop that precipitated the battery stopping charging.  Beyond that, I've already run through all the steps you listed, and I already used the documents you linked to run through all the steps available.  None of it has helped (note I cannot do the battery health manager steps because per the HP document that feature is not supported on this model laptop).

I've also now replaced the charger with another charger that is the OEM HP charger specific to this model laptop.  Replacing the charger has also not helped.

Any additional help is appreciated.

Hi@Lightwave22,

`We have done the basic troubleshooting as per the document and the notebook needs to be checked taking remote access so that get to know it's a hardware or software issue.

I'd suggest you contact HP in your region regarding the service options for your computer or HP Chat Support Team.
