Battery Drains While Shutdown

did a complete reinstall incl. wiping the HD.  No software or apps of any kind were installed.  Only windows updates.  Still had a battery drain problem. :(

did a complete reinstall and cleaned my hard drive of all documents.  Installed all windows updates.  No apps or other software were installed.  Still experienced a battery drain!! :(

Here is an updated report.  Last night I unplugged the surface from the charger and shut down at 100%.  I starter the machine and it was showing 94% power, a 6% drain.  The report shows it was at 86% after draining 6% while use after startup.  I cannot account for the remaining percentage.  Further research has shown many people experiencing similar issues but no resolution.

Here is a copy of the sleep study.  It only goes back to the 31st.  I am finding it a little difficult to read since it doen't seem to show battery power at start up.  Yet, it looks like on 6-1 I was at 86% percent and had only used 5% batter power which would make me conclude it was at 92% percent at startup.  I had shut down the evening before at 100%.  I may try this evening shutting down at 100% and seeing what the percentage is tomorrow evening.
