So after the December Firmware updates, my Surface was one of many which suffered from the 1 hour wakeup. Now I was patient with Microsoft and the issue is now fixed since the January 18 update. Another issue though, which used to work properly has arised. The computer just won't go to sleep. I've tried various things by playing around with powercfg and also the advanced settings in Power Options. Nothing seems to budge. I've tried resetting everything to default and disable USB suspend and restarting and all that but nothing seems to budge. I know some of you have had this problem even before December and I was wondering if it's just me or if anyway can give their SP2 a quick test run to see if auto-sleep is working for you? There's only one thread on the official Microsoft forums and it doesn't seem like it's picking up like the auto-wake issue which affected almost literally...everybody. I really would not want to reset the system because it'll take some work to even reinstall all the apps and what not so if anyone could help me out, it'd be great appreciated!
