Yes & No. When I was having sleep issues I tried overriding srvnet & doing so, by itself, didn't resolve my sleep issues ... but then I didn't & still don't know what exactly was causing the PC not to sleep before I re-installed of Windows in June.
For the NO part ... these days I'm using
SmartPower to manage when my PC goes to sleep or wakes up. SP monitors the Power Request queue & if there are active requests will keep the PC awake. I'm not sure, if issuing a override will work with SP ... I intend to ask the developer as he was very responsive to several questions I had about SP several months ago.
I use SP because several, potentially long running pgms that I use, such as, Internet Download Manager (IDM) do NOT create a active power request whilst they are doing their stuff ... bloody stupid I say.
With regards to IDM, I sometimes schedule D/L's to start in the early hours & I use SP to wake the PC 5 mins before the D/L's start, use SP to monitor the network activity to keep the PC awake while IDM is D/L'g the files. Once the D/L's finish the PC will go back to sleep.
I'm also very much a smartphone newbie ... the S4 is my very 1st mobile phone which I purchased only about 6 months ago. I don't use the S4 much beyond phone calls & SMS msgs. So I don't really need to connect my phone to any device!!! No big loss + I would have thought that having this option DISabled or OFF would have prevented the connection. IMHO that's a bug in Android KitKat.
