Battery charging Problem, New firmware?

I charged mine up last night, used it for a short period today and turned it off, not sleep or hibernate. When I turned it on this evening, battery was dead. Trying to see if system restore will take care of this.
 
Mine keeps changing mind on what 100% is still.

After system restore I installed all the updates except the firmware. Everything is back to normal. No more automatically installed updates from now on. Problems persist so I restored back again and did not install any of the updates.

I like to control the time, status and circumstances present when doing an update. Consequently I have always chosen "check for updates but let me choose whether to download and install them". This policy has worked well for me. I would recommend it to be the default choice for Windows Updates.

This is strange. I ran the command prompt and entered that ( copy and paste ) and it made a report with a .html extension but none of my browsers will open the file.
They all say they can't find it when I point them to the file to open.
Being a .html file browsers should open it.
I tried using Word but that wouldn't work either.


From the command prompt:

powercfg /batteryreport​

Odd. Try typing battery-report.html from the command prompt (same location from where you ran powercfg), and windows should open it a browser for you.
 
This is my report. System is a week old.

BATTERY 1
NAME X863568
MANUFACTURER SDI
SERIAL NUMBER 291E
CHEMISTRY LION
DESIGN CAPACITY 42,002 mWh
FULL CHARGE CAPACITY 41,788 mWh
CYCLE COUNT 2
 
Didn't work.

I tried also going to the file in Explorer and right clicking and selecting Open and it tries to open in IE but says it can't find the file!!

So I tried renaming the file and that didn't help. I took the dash out of the title thinking it might mess things up, but that wasn't the answer.

Very strange that it can't find the file when it is pointed right to it.

I went into the properties and changed them all so all the users had total permission to do anything with the file, but that didn't fix it either.

Battery report of my brand new surface:

Design capacity: 42 mWh
Full Charge capacity: 30 mWh

The most bizarre thing is the table showing the Recent Usage. The first days, the maximum Capacity Remaining shown was 100% (41 mWh). Now, sometimes the maximum capacity shown is more than 100%, but only 33mWh

2013-12-15 00:17:47 Suspended 74 % 31 mWh
00:18:41 Active Battery 98 % 31 mWh
00:21:24 Suspended 97 % 30 mWh
00:32:13 Active AC 107 % 32 mWh
00:33:16 Active Battery 108 % 33 mWh
00:33:23 Active AC 108 % 33 mWh
