IPad is able to receive push messages while it has screen turned off.
Is it possible to receive push messages with WinRT device in sleep mode?
I would guess it is not possible with Intel based pro models…
Note. This is quite important issue when planning for Windows RT applications. Chat application could be made if somekind of alert could be given to user. Pro models can run real Windows Desktop apps, which can alert user when running at backround…
based on this whitepaper http://www.microsoft.com/en-us/download/details.aspx?id=30703 and what i have read before, there is a connected standby..
the whitepaper talks about background tasks working as should. no mention of notifications per say but i’d imagine they should be work as well. Apps however will be in suspended state at that point
