I cant conform im having the same exact issue as you show here, there I I noticed when I turn off the tab the fan goes off so I think its hibernating and o leave it alone mabe the fan comes on later not sure, but do notoce the huge battery drainage. I leave it at full charge during night, and when I try to awake it the light on side is yellow\brown and while I try to boot it up it goes to bios screen and battery is drained to 10% probrslly the battery is down so it goes into bios. there is huge drainiage while I leave the tablet on standby at night, and a little less when its shutdown. but I am noticing the battery drainage not the fan on and off

Hi Skyrida,

Thanks for confirming that someone else is seeing the issue.  In relation to the fan, I have only noticed it once or twice and usually right after it goes to sleep - potentially because the processor is still warm or something.  I have figured out that the "sleep" that the tablet goes into is called "connected sleep" which means that it is still able to download program information and data such as mail and news feeds (not sure what else).  If you managed to get you tablet into true "hibernation", then the battery should remain pretty level during that time.  However, you will notice that hibernate is not listed under the shutdown menu or really anywhere else.  

I wonder if Dell could chime in and let us know is 3%+/hour drain in sleep is typical.  Seems way extreme.

Just to be clear on how Windows 8.1 works now....

You have sleep mode, where the device just turns off the screen and is still otherwise active.    After this, you have connected standby, which is what happens when you hit the power button briefly or let the device sleep for long enough.   In connected standby, the device can still wake up periodically (in the background) and turn on WIFI to check for important updates.   Connected standby is only supported on the Atom and iCore devices - not the Vpro devices.   The idea here is to mimic how a cell phone works when in standby (e.g. still talking to the network and alerting you if a call comes in, etc).  

With that being said, I don't think your device should be completely draining the battery overnight while in connected standby mode.

Thanks guys- have asked our resources to attempt to duplicate and investigate further.    Certainly seems like this could be related to the other hang issues.

Thanks Brian - appreciate your help.  I think we all agree that it is a nice product just want to get the full potential out of it.

Gotcha - thanks for the quick reply Jones - How's your battery life in "sleep" with the vPro?  I can trick my tablet to go to "hibernate" to save battery, but that bootup process is about 5-10 seconds.  Maybe that is what the vPro is really doing - or at least a level of hibernate.

Is there any documentation detailing all of these "differences" between the Vpro and non-Vpro chips? My dell rep sold our company 10 of these devices from your Smart Selection configuration which included the Vpro chips. Now I hear that I have diminished functionality, a 3-4 second delay before the screen comes on, etc., all without being advised of the caveats of going with that configuration.

Michael,

   That processor does not have the Vpro technology: http://ark.intel.com/products/76611. The Vpro stuff is in the i5-4300Y processor configuration.
