    Sleep Draining Battery: Due to SD card? SleepStudy included

    I recently upgraded my SP3 Pro to windows 10. I have a 128Gb SD card in the slot for videos etc. Now the sleep sucks. Drains overnight. So am I reading this sleep study right? Is the USB device listed my SD card? This worked FINE under 8.1. I have seen others state the SD card was their problem...
