Experiencing the same and I’m also exacerbated from these updates. After a snafu with the SP2 update that caused similar problems, I had hoped to avoid updates for good. I made good with that promise
with the SP3. But with SP4 and Windows 10, avoiding updates is very difficult. But because I have the phantom touch problem, I’m in need of a proper update to fix it.
Fortunately pre 2/17/2016 update, I had no issues with sleep and only occasional issues with heat (always found a culprit and found rebooting fixed it). Immediately after the update my SP4 changed.
At first I thought it was a one off crash when the power button was unresponsive to wake. Then I thought it was related to my keyboard cover.
Pre update I may have had 1 or 2 nonwake experiences ever. Now it happens 5 times a day.
One observation is that under the new update, “sleepstudy” showed that my system is, for the first time, running in a low power state while asleep. I’ve never seen that before. I wonder though, if
the new low power state is causing the difficulty in waking.
Fed up with another hard reboot because of the non-responsive wake, I attempted a restore. Note, given my aforementioned desire to avoid certain updates, I’ve invested in understanding the use of
‘wushowhide’ where I can hide unwanted updates.
I checked the drivers and noted their January dates. Then performed a system restore. Dates rolled back to November.
Great!
Feels like the computer I had before the update.
I hide all the firmware updates – but apparently I couldn’t hide the one referred to as ”system hardware update 2/17/2016”. Before I knew it started to install.
My display adapter date changed to January.
I don’t know if I will experience continuous wake issues but after several short tests and a 30 minute test, I hadn’t experienced it yet.
Now what has me curious is if the new wake issue is related to the new low power state – which I believe I was able to roll back as evidenced in the sleepstudy.
Note the update caused the green low power state and at a Power rate of 38 mW which experienced a wake crash.
Now, I’m back to the numbers I have come to expect with the 350 mW rate and no crash.

I wonder if anyone here might have thoughts on this theory. Of course, I still may experience wake issues after posting this. So this is just a preliminary theory.
I would not recommend to anyone to system restore as I do expect some fix eventually.
