Title: No video after resuming from sleep - Windows 10 Anniversary Edition
Post by: Deozaan on September 03, 2016, 03:16 PM
Hi folks,

Shortly after I updated to the Anniversary Edition of Windows 10 Pro x64 I noticed that my primary display no longer gets any video signal after waking my PC from sleep.

I never had this issue before the update. Sometimes I can "fix" it (work around it) by remoting into my PC and logging in. Then the monitor gets a signal and things start working again. But today, when it happened again, even that workaround didn't work for me.

I haven't been able to find anything relevant in my searches for solutions. The closest thing I've found is people complaining about their lock/login screen being black after resuming from sleep. But that's just the background image they're talking about. Other UI elements and the mouse and everything still seems to work IIUC.

Does anyone have any solutions or troubleshooting suggestions?



More info that might be pertinent:

My GPU is an AMD Radeon HD 6870. I have a dual-monitor setup. The primary monitor just flashes the LED at me like it does when it is sleeping due to no signal. The secondary monitor appears to wake up properly, but just displays a black screen since it's normally black/blank on the lock screen anyway. If I move my mouse around, sometimes I see it on the secondary monitor, but it kind of comes and goes over the course of a few seconds.

Update your video-drivers, or installing a WHQL-qualified release should help, IMHO.

It seems I'm already using the latest drivers. But the GPU is considered "Legacy" and drivers for it aren't being updated anymore (http://support.amd.com/en-us/download/desktop/legacy?product=legacy3&os=Windows+10+-+64).

But I've been running Windows 10 since it released a year ago and it's never had this problem until after the Anniversary Update, so I know it "should" work in Windows 10. Honestly it's probably about time to upgrade to a newer GPU anyway (the fan is starting to make a lot of noise) but it's not in the budget at the moment.

There are beta drivers for the HD6000 series (I'm running a 6850):

Beta is available here (https://support.amd.com/en-us/download/desktop/legacy?product=legacy3&os=Windows+10+-+64) - if you have trouble getting it, I have the installer available (x64 only).

An aside:

I'm also surprised that what I thought was a lower-to-mid-range GPU I got 5 years still ranks fairly high up there according to this chart (http://www.tomshardware.com/reviews/gpu-hierarchy,4388.html), and spending the same amount of money today that I spent on it 5 years ago will get me a GPU that is only three tiers higher on that chart. It would move me from the 12th best tier to the 9th best tier. :(

I certainly expected the price to be lower or the performance to be much better by now. :-\

From experience, the relative "newness" of the GPU drivers may be irrelevant. Sometimes the "latest" GPU drivers may not actually be "the best" for a given case. It is worth experimenting.

Again, from experience, the noisy fan thing may also be irrelevant. The word to use here is "maintenance". Try dismantling and cleaning the fan and heat exchanger, and especially cleaning/lubricating the fan spindle with CRC, or something that doesn't offend electrics - that can make a world of difference. Make it just like a new fan.

Make it just like a new fan.

This is the 2nd fan on this GPU after the first one completely failed.

It was noisy, like it is now, so I took it apart and lubricated it with WD-40. It was nice and quiet for a while, but it wasn't long (as in a month or two) before the noise started up again. Eventually (months later) it ground to a halt and when I took it apart again I saw what appeared to be ruined ball-bearings.

You saying "something that doesn't offend electrics" caused me to do some research. I see now that WD-40 is bad for electronics and may have been what caused it to go from just noisy to completely broken. Oops! :-[

Anyway, I contacted the manufacturer after the original fan failed and got a replacement from them (because it seems to be non-standard and I couldn't find a generic/replacement fan online anywhere). Once again it was nice and quiet for a while. But after only about 5 months it started making some noise again, which came and went for awhile. That was nearly 2 years ago and now the noise is pretty consistently there. I haven't attempted lubricating it since I figured it was just a faulty design (and saw other similar complaints in reviews for the product). But now that I know it was probably me who ruined the last one, I may spend a few bucks to get some proper lubrication (https://www.amazon.com/dp/B00BYCKTW2/) for it and attempt it once more.

It sure would be nice to have a quiet GPU again. :) Well, quiet is a relative term, since by default it comes with two speed settings: Loud, and louder! (But I use SpeedFan to reduce the fan speed to make it quieter when it doesn't need to be running so fast.)

Failing fans on GPUs is quite common where I live. Subtropical ambient temperatures and often humid...that doesn't help with longevity of fans. That is to say, GPU fans. Case fans are much "sturdier" in my experience and if you don't care much about the looks of the GPU inside your case, then try to fit a case fan onto the heatsink of the GPU.

Fugly, but your GPU is getting lots of cooling and depending on the model case fan, it can be a very quiet solution. Even if you cannot mount a case fan directly, putting an extra case fan as close as possible to the GPU also works quite well. Especially if you can make some sort of funnel to pull the heat from the GPU. Case fans are much easier to replace or maintain and usually cost much less than a new GPU.

@Deozaan: Yes, using the wrong lubricant can apparently tend to wreck your nearby electrics and conductivity, though being somewhat cautious and having read of others' accidents in this regard, I personally have avoided making the same mistake.

I used to use CRC as that is a superb penetrating lubricant and it says it is good/OK for demoisturising car ignition contacts, but over the last few years I've been using something called inox-mx3 for things like laptop cooling fans as that says it's OK with electric motor windings, etc..
Laptop fans are beautifully simple bits of engineering, albeit a bit delicate, and in their normal operational position (upside down) they hang in the air by magnetic force attraction to their spindle and its base, and they are thus virtually frictionless. With occasional maintenance, they could last for ages. It's probably best not to let them run too long in a noisy or laptop-overheated state though - same probably goes for any PC (CPU/GPU) cooling fan.
I just wish laptop manufacturers would make them easier to get at for maintenance work.

Good idea to use SpeedFan too. Is very useful. I discovered a while back that SpeedFan has an option Info-->DIMM Info-->Read Info that can tell you all about your installed RAM - very informative. It apparently gets the info via the SMBus, but doesn't seem to work with all SMBuses - or maybe the RAM is connected to a different Bus in those cases, I don't know.

There are beta drivers for the HD6000 series (I'm running a 6850):

I didn't think I wanted the beta because:

  • It's a beta (implies unstable) and won't be updated further.
  • The download link says it is non-WHQL.

But I guess I'll give it a try and see what happens.

I installed the beta drivers and let my machine sleep overnight. It just woke up fine without a hitch. I'm cautiously optimistic that this issue is fixed, but we'll see how it handles sleeping a few more times before I say case closed.

___________________________
I just had a thought about that - overworked PC fans.
I'm not trying to teach my grandmother to suck eggs here, but I wondered whether some experiential tips/thoughts that have served me well might also be useful to others.

Humidity helps for cooling:

The fans may be defeated from having any effect:

The waste heat may not be getting to the heat exchanger:

SpeedFan is very useful, but...:

Conclusion:
So what I would suggest is, if you haven't done so already, then replace the thermal grease on those chips (or whatever they use in the PC hardware heatsink interfaces), as described above. This will remove one possible cause. After that, if the airflows are clean, the fans are in good order, yet the chips don't perform like they should, then - whatever the cause - they are probably permanently damaged and they will need to be replaced. To test this hypothesis, try replacing them with any old (working) spare you might have access to, and see if that eliminates the problem.
The fan systems will also need to be inspected/maintained, as they will have probably been operating outside of their normal performance range for extended intervals. This may have caused some mechanical wear and tear.

I've let mine install the Anniversary Update, this is the driver I'm using:

[ You are not allowed to view attachments ]

And it resumes from Sleep fine, I'm using HD6850 with HDMI to an AOC I2470Sw and DisplayPort->DVI to a Dell 1701P.

Don't think it'll make a difference but FWIW I'm running an AMD chipset.

EDIT: Spoke too soon, I just had it happen for the first time even though the Anniversary Update was done a week ago.

You'll probably see that the Event Log is full of this:
[ You are not allowed to view attachments ]

It appears it can happen even with a reasonably recent card: Event 4101 Display driver amdkmdap stopped responding and has successfully recovered. (https://community.amd.com/thread/205566)

More (https://community.amd.com/thread/204624)

From here (http://www.tenforums.com/general-support/61466-warning-event-id-4101-a.html):
Warning Event ID 4101


    Hi TenForumers.
    Few days ago I found some strange warnings concerning the display driver (event ID 4101):
    "Display driver amdkmdap stopped responding and has successfully recovered".
    After trying this and that with no avail, I noticed these warning were raised when I was using my Internet browser (Firefox):
    sometimes my browsing experience suffered of occasional "blocks" of 1-2 secs (with a Warning 4101 coming out in my event viewer).
    I turned off hardware acceleration on my browser's settings page and I eventually got rid of those warnings.

    I'm writing this post hoping it could be useful to someone with the same problem.

I did have Firefox running at the time the machine went into Sleep so I'll disable HW Acceleration and see what happens.

I've also noticed that maybe it has to do with the length of time the computer is sleeping. If I put it to sleep and wake it up immediately, it seems to work just fine in my tests. Sometimes when I put it to sleep and wake it up within about 8-9 hours it works just fine. But if I let it go closer to 12 hours before waking it up again, it seems to fail much more often.

That said, I have never properly logged any of the times or paid close enough attention to say for certain that this pattern is true. It's just what it "feels" or "seems" like to me when I experience it, because sometimes it works fine and other times it fails.

I've just started either leaving it on all night long or shutting it down completely at night, so I don't lose any work in the morning when I attempt to wake it from sleep.

Well done Microsoft, second time in less than a week since I installed the Anniversary Update after 12 months of not a single occurance since installing Windows 10.

So, hope for the best, plan for the worst and all that - I've restored the system image I created before I let the Anniversary Update happen.

They can take their Anniversary Update and stick it in a dark place.  :)

Oddly enough, I had a look at the restored System Event Log, not a single Event 4101 to be seen.


And a FYI re. the times my computer sleeps, almost always less than one hour, (over meal times longer than 20 minutes).  System is shut down overnight unless there is a video encode happening.

I was surprised to receive a notification a day or two ago saying AMD had a driver update for me. I thought, "Wow! They updated their old, discontinued driver to support the Anniversary Update! Nice!"

I let it run its thing and then it told me it was running the latest version after all. :mad:
Title: Re: No video after resuming from sleep - Windows 10 Anniversary Edition
Post by: 4wd on October 06, 2016, 04:43 PM
That's because you installed the beta driver, the newer Install Manager for the Radeon Crimson software checks for updates but unfortunately it doesn't seem to take into account what graphics hardware you're running before it does.

I completely removed all AMD software and then reinstalled the latest applicable.

Edit: Had the wrong program referred.

BTW, one thing I also noticed with the Anniversary Update, Windows Defender would no longer do scans in the background, ie. you couldn't close the window as it would say it would cancel the scan ... there's a backward step.

Did you ever manage to find out what was the reason or did it come good in a later update, Deo?

Did you ever manage to find out what was the reason or did it come good in a later update, Deo?

I had stopped putting my PC to sleep and instead either left it running or shut it down completely to avoid the issue.

Eventually I forgot that I ever had this problem and probably around the new year I began putting my PC to sleep at night again and the problem hasn't happened yet.


But as of about mid-December, my other monitor has started having issues when I turn on my PC, though I'm fairly confident it's unrelated. My screen is a pale grey, then looks like "clouds" form on it, then there are either some bright or dark lines of pixels that show up at the top, soon replaced by several lines of glitchy pixels at the top of the screen which gradually expand down toward the bottom until finally the picture comes back, but the colors are messed up. Once it reaches that point, I can shut the monitor off and turn it on again and the colors are all good. But if I try to restart the monitor earlier in the process, it continues about from where it left off. It's like it needs to "warm up" a bit first. It has happened both when resuming from sleep and also when powering on from an off state.

I took a video of it using my tablet. It seems to be worse and last longer since I took this video:

Maybe I'll give the Anniversary Update another go again, who knows, it might decide to work on my machine.

Re. the monitor, first thing I usually think of when anyone mentions a TV, monitor, computer, or such needs to "warm up" before it works properly is the electrolytic capacitors in the switchmode PSU, (or main board),  have started getting way out of spec due to age.

Can be replaced easily enough if you're competent with a soldering iron but there are some lethal voltages lurking in the PSU, especially the discharge from the main capacitor.

Salvaged plenty of things just by replacing the capacitors in the equipment, spending <$20 and an hour or so has always been preferable to spending a lot more to replace the equipment, eg. salvaging a discarded complete Dell XPS730 by replacing 5 capacitors on the motherboard  :D

Failing to come out of sleep has been happening to me, ever since anniversary too, may be even before anniversary actually. I blamed it on it being an Windows 7 era Vaio not officially Windows 10 supported. Have been doing same thing as no sleep, only shutdown or on.

Not to hijack, but if anybody reading this has any advice for my version would be appreciated.

I'm usually glad to take things apart and tinker with them. But I decided I'd better not ever mess inside of monitors when I learned about those lethal voltages.

Wasn't this high voltage thing a thing from the past? CRT monitors/TVs needed 10.000Volts to get the system started, but I thought that such high voltages aren't required for LCD-/LED-based monitors or TVs.

Of course, a jolt of 220-240 volts or 110 Volts isn't fun either...

You're correct, it's not high voltage as such, being below 1000V it's technically low voltage but still hazardous/lethal.

The main capacitor of a switchmode PSU can discharge around 350-400V, it's usually the biggest and closest to the AC input, can be anything around 220-400uF.

This problem went away once the weather warmed up. And suddenly this past week when it finally cooled down again the problem has returned. So it does seem to be related to the monitor's temperature.

There you go, this problem seemed to have been fixed in some MS update at some point since it hadn't occurred on my machine since a couple or so months after the initial Anniversary Update.

Have now upgraded the HD6850 to a RX560 and it's back ... terrific  :-\

Machine is totally unresponsive trying to wake from sleep mode sometimes which then needs a push of the reset button.

Time to dive into the Eventlog and Google again.
