This as happened 5 times now. Have a Surface Pro Ver 1 connected to a 7 way USB 3 externally powered distribution hub. If I put the Surface Pro into Sleep, Shutdown or Hibernate overnight with the 7 way usb hub externally powered it only starts with Volume up and Power On over 10 seconds? Also it does not update time and date it thinks its never shutdown. If I depower the 7 way hub then shutdown the Surface Pro it restarts OK. Just press Power On. The 5 volt external supply via the USB is effecting the Surface? Anyone had similar problems?
