Read somewhere that you can turn Hyper V on, change the power management setting on the network adapter to not turn off to save battery life, then turn Hyper V back off and the setting should stay and that could fix your network problems. Every time I do this afterwards if I use the power button, to enter sleep mode, or let the screen turn, I have power my SP3 back up using volume up plus the power button. My SP3 refuses to sleep just powers off. Is there a way around this? Sorry if I have already asked this using a few different forums and tend to mix things up.
