I had to repeat the process two more times before it worked.
The rear cover was unexpectedly difficult to remove and there was one hidden screw behind a rear rubber footing strip.
The battery display now reports plugged in and charging and 39%. I won't be satisfied until I see charge go to 100%.

Hi! @Denizen,
Thanks for the update.
Please try the steps recommended below and check if it helps.
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.
Also, try the steps recommended below.
Remove the AC adapter and discharge battery capacity to 10 percent or lower.
Re-connect the AC adapter and check if the battery can be charged to 95 to 100 percent (95 to 100% is normal).
If upgrading to F.45 does not fix the issue, replace the battery.
If replacing the battery does not resolve the issue, follow the standard repair process to get the issue resolved.
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.
Let me know if this helps!
Happy Weekend ahead! 🙂
