Hi, Just got a Surface 3, windows 10. Have all the latest firmware & windows updates. Everything works fine, however when I put the device to sleep, the battery is still used quite heavily. Using powercfg /sleepstudy, I see that the Avastar wireless is responsible & is in use 100% of the time during sleep. I don't see lots of other threads with this problem - am I alone? Or is this a buggy wifi driver issue? Thanks!
