Since the recent firmware update, I have found that my Surface Pro 2 no longer goes to sleep when I close my Type Cover 2 or press the power/lock button; it instead appears to hibernate. Before the update, when I closed my Type Cover 2 and then came back and opened it later on, the Surface would wake instantly to the lockscreen. However now when I open the Type Cover 2, nothing happens, I actually have to press the power button which brings up the Surface logo for a few seconds before taking me to the lockscreen as if it is coming out of hibernation instead of sleep. My programs and documents are all still pen like they were beforehand, however this short wait is rather annoying when I'm so used to a quick wake when I just open the cover. I have checked my power settings and it is still set to sleep when I close the lid, not hibernate, yet it still appears to hibernate instead of sleeping. Is anybody else experience this issue, and does anyone have a fix?
