I have a surface pro 4 i5 4GB that has all the latest updates. When I "shutdown" from the menu, I find the battery still drains over night (5-10%). I mainly use a work laptop so I only occasionally use my surface. So after a few days of non use, I sometimes find it completely dead. I tried a shortcut to shutdown "C:\Windows\System32\shutdown.exe /s /f /t 0" hoping this will fully shutdown and prevent battery drain but unfortunately I am still seeing similar battery drain. Is there a way to completely shutdown so I don't see battery drain? Thanks in advance.
