Surface Pro 4 - Screen won't wake from sleep

OH NO!  IT'S BACK!  I guess any more than about three months without the Intel/Microsoft Power Management Monkeys screwing up my computer was too much to ask...

Things were *finally* starting to work mostly as they should, and I hadn't had to do the YAPORRAC dance (Yet Another Power-Off, Reboot, Restart Apps Cycle) for weeks.  Unfortunately, this week's update has my SP4 failing to wake about once a day - so far, it's always been when docked, but I haven't done much out of the office this week, so it hasn't had much chance to fail to wake when undocked.

I'm currently at 14393.576, and for the first time in a long time, I'm back to at least daily failures to wake.  I'm not actually sure if the offending release is KB3206632 (the most recent one), or the previous one, KB3201845, which was replaced by KB3206632 in only three days.

Anyway, after being pretty stable for a long time, this is definitely broken again.  Who else is having this problem again?

Mine had that problem,  and the issue of locking up when I first got it. After about a month, when it had downloaded several updates, those problems disappeared.

3. I don't know for sure if this is related, but in the past two weeks, I've lost touchscreen(and pen) access two or three times.  It comes back after a reboot, but at least once, it came back after several wake cycles WITHOUT a reboot.  (Nothing shows as wrong in Device Manager.) This is my biggest concern now, as it makes OneNote effectively useless and again you're left with forced poweroff as the only option if you don't have a Type Cover with you...

^This. I'm on my third SP4 now (touchscreen failure on the first, complete loss of SSD on the second) and on my second day of using the replacement, I lost touch and pen just as you described, after waking from hibernation. Suspending and resuming brought the screen back. Right now I'm debating with myself whether I should return this replacement as well, or if this is a software regression that will hopefully be fixed soon™.

My patience is running low...

I haven't updated in a while, and I wanted to take the opportunity to report good news.  Somewhere in the weeks after the 1607 (Anniversary) Update, sleep/wake and power management started working pretty much as it should.  I haven't had a SoD event in quite some time now.

Although it took nearly a year to get a fix, kudos to the Microsoft engineers for coming up with a fairly viable software/firmware solution to a hardware failing.  I'm familiar with the degree of difficulty of fixing problems like this, and it's off the scale.  Again, great job got getting this far, but there's still a bit of flakiness to wring out - please keep fixing the SP4 and don't just transition over to SP5/SB2 development, even though I'm sure there's pressure that way now.  Please honor those of us that toughed it out, stuck with you, and didn't return our SP4s outright by making it work as well as you possibly can.

My three biggest complaints with the SP4 now:

1. Although sleep/wake works, battery life still sucks pond water.  There may not be anything to do about this, due to power management (esp. S0ix) just being fundamentally broken in Skylake, and the battery being sized assuming S0ix works ; 
2. There are still bugs and instability in the sleep/wake code, especially around USB and Bluetooth - these often (at least a few times a week) prevent my SP4 from sleeping properly in the SP3 dock;
3. I don't know for sure if this is related, but in the past two weeks, I've lost touchscreen(and pen) access two or three times.  It comes back after a reboot, but at least once, it came back after several wake cycles WITHOUT a reboot.  (Nothing shows as wrong in Device Manager.) This is my biggest concern now, as it makes OneNote effectively useless and again you're left with forced poweroff as the only option if you don't have a Type Cover with you...

Overall, though, I'm willing to call this one pretty much fixed, at least for me.  Hope others are faring as well...
