I have only experienced a crash waking from sleep once or twice (wake, but black screen with backlight obviously on). I did have problems with it crashing when waking from hibernation and the display driver crashing during the sleep-hibernation transition, but I have not experienced these problems for a while. Give sleep mode another try - what's the worst that can happen...
I don't want to change my power settings and make my device crash (technically metro is broken for me so I can't change them anyway).
Have they fixed the bug where the device crashes when being turned on from sleep? I'm very annoyed having to hibernate my device every time.
I'm now convinced after fighting this problem for a couple months it is hardware related for those having it on more than the rare occasion. My previous SP2 wouldn't wake reliably on a daily basis, drove me nuts. Did an advanced exchanged and my replacement has been 100% stable for two months now, waking every single time successfully.
Sorry to hear they haven't fixed this, and also sorry to hear that it might be hardware related.
I'm scared of doing an advanced exchange because the last time I did they sent me an even older surface, and the colours on it were quite strange but what troubles me is they've had a $1000 hold on my credit card for over 2 months, and have not removed it yet..
Normally I would say sell that sucker for whatever you can get and head for ze hills. But with those issues it has, you'd likely have another headache to deal with when the other person finds out. I would just keep calling MS as much as possible, trying to escalate your case higher until you reach someone who will get you a new surface or better yet, a refund (if bought from an MS store).
