Windows 10: Power Button Stops Working Until Restart in Windows 10
Power Button Sleep Stops Working Until Restart in Windows 10
I upgraded to Windows 10 from 7. Since the update I've run into an issue where, after I've been using my computer for a while and have done a few sleep/wake cycles, I won't be able to put my computer to sleep with the physical power button. It wakes up just fine with the power button. Restarting my computer temporarily resolves the issue.

I have the same issue. I posted previously, but it looks like It got removed, but had no explanation. Probably because I mentioned some software that might not be legit.
I'm still looking into it, but haven't found anything yet.
I installed my Windows 7 from an official ISO, so I don't think that's related. I may have just noticed a new symptom, though. I tried to wake my computer this morning using the keyboard. The num lock light on the keyboard came on, but the computer did not wake until I hit the power button.
I've tried numerous things. I rebooted, and then pressed power button, it's all okay, I've played a couple games, gone to go to bed, and it's screwed up again. I literally have nothing, and can't find anything with a proper solution!
I'm also getting this.
Legit Windows 7 Home install from late 2012 until last week. Power button always put the computer to sleep no problem.
I ran the Windows 10 upgrade, then did a clean format and install. The power button refused to do anything when I tried to sleep it yesterday, so I rebooted and it seemed to work so I chalked it up to a one off. Then it did the same thing again this morning. It seems to sleep okay from the start menu, but this is very annoying.
I tried powering down the whole system instead of sleeping, then powering back on, leaving it for 24h and the power button DID put it to sleep after all that, so it appears it can do one sleep/resume before it stops working. No idea what would cause this and I don't really want to try BIOS updating for something that appears to be exclusively a problem with Windows.
It seems the upgrade from Windows 7 isn't related. I did a clean install from an ISO I made with the Windows Media Creation Tool, and the issue is still there. I submitted the bug using the Windows Feedback app built in to Windows 10. If those of you with the same issue want to upvote it, you can find it by searching the feedback app for "physical power button on my computer" with the quotes.
Thanks for updating. Hibernate seems to work consistently, though it crashes video drivers.
I tried disabling deep sleep (suspend to memory), and I think it worked, though it doesn't turn the fans off, which defeats some of the point. I also get the following error in the event viewer resuming from deep sleep (the one I can do only once per reboot):
The system firmware has changed the processor's memory type range registers (MTRRs) across a sleep state transition (S4). This can result in reduced resume performance.Event ID: 137.
I'm not getting any events with ID 137. The only two kernel-power source events I'm seeing are when it goes to sleep and mentions the cause is power button or lid, and then the wake event which says "Firmware S3 times. ResumeCount: 1, FullResume: 967, AverageResume: 967".
I believe I've narrowed down to issue to when I wake up the computer with the power button, then it won't go to sleep again with the power button. I was mistaken about needing to restart Windows to get the power button to work with sleep again. If I use the start menu power to sleep because the physical power button isn't putting my computer to sleep, then wake it up with the keyboard, I can then sleep the computer with the power button again.
Can anyone confirm their computer is behaving the same way?
a bit of an irritant - anybody else had this and do they know how to fix.
The Automatically hide taskbar / quick launch bar suddenly stops working until next re-boot. No rhyme or reason --just stops randomly.

This happened on the previous build as well but I was hoping it would be fixed with the newer build. I have a AMD R9 280X GPU which I connect with an HDMI cable to my one monitor with built in speakers (ASUS). Any time I restart or shut down my...
Start button not working is a known problem and is supposed to be fixed by KB3034229. That update does not show in Windows Update. I also tried a direct download from
sfc log file attached, looking for inputs.
symptoms include but no limited to:
-mouse over bug, toolbars changing in colour being greyed or highlighted, but will not return
-drives appear empty, until complete freeze
