Why are Windows machines doing ANYTHING in sleep mode? Here's a tip, MS: shut that **** off. If the machine is sleeping we don't need you force feeding it. No wonder the battery sucks in these things. :/

Well one example could be Windows 8 tablets (Like my Surface 2) that will periodically check for updates for App content, such as Twitter updating in the background.

I've not used sleep much so far on my Surface as I've only had it a couple of months but when I have I've not noticed any additional battery drain so if it want's to update in the background that's fine by me.

If you don't like it updating during sleep, use the "Shut Down" option instead to fully power it off, simple enough.

Because Microsoft didn't write the device driver, and that driver decided it needed to do something is one very common scenario.

But if you'd bothered to read the post, you would know this is for ConnectedStandby state, which as the name implies is connected. Network still functioning, USB devices still drawing power for whatever reason those devices wish.

If you are going to be critical, complain that it took them this long to make such nice functionality, and that it requires a power management level few devices support!
