I have a similar issue as the original poster. SP3, no hyper V or realy anything changed on the power profiles. When it goes to sleep (presumable Connected Standby) and I touch the windows button on the device it takes 3-4 seconds to wake up. It certainly doesn't feel 'Instant'.
Any suggestion on how to improve this?
Is anybody receiving e-mail notifications, Skype messages/calls and such when their SP3 is asleep? From what I read that's the whole point of connected standby, fast resume and notifications. When mine sleeps I get no notifications at all, Skype shows offline to others, etc. Then when it wakes up I get an avalanche of messages/notifications. It seems to me that Wifi get's disabled/turned off during Connected Standby but i'm not sure how to verify this.
To me having a device that functions as a tablet and a laptop should have these functions and I thought SP3 could do this when I bought it.
1.5 hours with the techs at the MS Store resulted in them first denying SP3 was Connected Standby enabled, then they asked me why I needed such a feature? Last they suggested I change the power settings to not let the device fall asleep. I had hope the techs at the MS store were knowledgeable about their products, but when I explained the issue they went on google to find out about. They had never heard of InstanGo and said only the original RT supported Connectec Standby and Push Notifications....sorry ..rant over.
