Windows 10 Why would a Surface Pro 3 with Windows 10 Shut Down for Low Battery Warning, while Running on AC Power?

[MarkBC01]

Issue:

1. Today (3/20/18) my Surface Pro 3 (I7, 8Gb/256G) suddenly shutdown with a screen message declaring Low Battery power, Windows is shutting down.
2. However, the machine was plugged into the MS dock at the time, and the connection to the dock was good. At least (1) the light on the magnetic connector was lit and, (2) both peripherals were fulling working [1 USB drive, Logitech wifi keyboard/mouse adaptor) .
3. When I restarted (unplugged) the computer started without issue -no restart message (Your computer etc. etc.).
4. The task bar indicator indicated fully charged 100%, and the machine runs well as if it really does have a full battery.
5. The action occurred while typing in a notepad app window. MS Outlook, and Google Chrome also were open apps in background

Equipment Summary:

• - This is a Surface Pro 3 I7, *Gb ram with 256g SSD connect directly via MS video cable to an external HP Pavilion 27 xw monitor, and a MS Dock connection for power, for an external (6Tb) HD, for a Logitech wifi keyboard/mouse combo.
• - The Windows Version is: Windows 10: MS Ver 1709 (OS Build 16299.309) with all updates automatically applied as soon as they come out.
• - Below is the Battery Report that I ran immediately after this incident.

Questions:

Q1a. Could somebody please let me know what could cause this? [And]

Q1b. Is it a known bug or issue with this version of Windows or Surface Pro 3 I7 8Gb 256Gb?


Q2. Is there any action or fix I can take to eliminate any repeat of this.


Thank you in advance very much for any helpful information or support on this issue!
