Windows 10: Surface Book battery drain while turned off

As the title describes, it happened this morning after charging it the night before to 100%, I disconnected the power source and had it on for a few minutes then turned if off. About nine hours later, I turn it one (without power chord) and it was at 33%!!

I ran a powecfg report and the cycles (~100) and watts seem normal.
I ran a sleep study and it showed a "abnormal shutdown" around the time I turned it on. Info is below.

The system is up to date per its own autoupdater.

Any suggestions?

Failing battery or draining issues?


Bang! Problem solved! I also posted this in Neowin: Do I have a failing battery? Or is a program draining the heck out of it? - Surface Pro 3 - Hardware Hangout - Neowin Forums

I was suggested to reinstall the drivers. Device Manager didn't expressed any anomalies, but reinstalling the drivers yielded outstanding results. The device now lasted 4 hours and 23 minutes. The last hour and 23 minute was with the device playing music in Media Player Classic with the display always-on at 100% brightness and the volume 80%.

Thanks for everything *Biggrin *Biggrin *Biggrin
