Screen garbled/tearing in Windows 7 when waking from Sleep (GMA4500)

idata — Thu, 04 Feb 2010 18:27:50 GMT

I have a Toshiba Satellite Pro with the GMA4500 integrated graphics. I'm running Windows 7 Enterprise (equivelent to Ultimate). The graphics are running perfectly, however if I put the laptop to "sleep" and leave for longer than about 20 minutes, when I wake it the screen is a mess with large areas of what can only be escribed as TV static (but with colours). At first I thought the laptop had a faulty conenction but no, this only occurs when waking from sleep.

I have updated the drivers, tried drivers from Toshiba and Intel site. Currently on the latest ones from Toshiba - which match the latest Intel version - I suspect its the same file.

To fix the screne I have to restart the laptop. If the laptop wakes from Hibernate it is also fine. In fact its rock solid except for this issue.

Any ideas on this one? Tried changing resolution etc to kick the driver/chip into life but the problem persists until a reboot.

I am also having the same issue on an Acer 3935 and again the only way to get rid of the problem is to restart the laptop. Although upon start-up windows loading up screen and boot screen etc... there does not seem to be any artifacts/screen distortion, making me think that it may be a driver issue but i have the latest drivers.

Any help would resolving this problem would be appreciated.

Thanks

I've been having this identical problem after integrating driver version 8.15.10.2021 into my Windows 7 Ultimate 64 bit installation DVD (and installing it obviously). I encounter the problem when I put the computer to sleep while on battery, wait some time, plug in the computer, and resume. The problem can be fixed by restarting, or by sleeping again, unplugging the power cord, resuming, then plugging it back in. It's almost certainly a driver issue since the cursor and some windows can appear on top of the artifacts, although the artifacts are not captured in screenshots. My hardware is a Sony VGN-FW270J with the latest Intel drivers for my 4500 MHD.

So does the issue relate to changing between mains and battery power when going to and coming out of sleep? Or is it down to the drivers Power Plan for the chipset. By this I mean that if it wakes on mains and tries to implement a Full Speed power plan when the chip and driver originally went to sleep on the Balanced or Max Battery plan.

It's a weird one. I still think this is a driver issue, but may be a chipset bug. Either way thanks for the advice.

To summarise....

Rather than Reboot simply put the laptop back to sleep, changing power from Battery to Mains, or Mains to Battery - basically away from the power type that corresponded to scren distortion. Then wake from sleep. If this works you can then revert to the power source of your choice.

Answered - in terms of a working solution that doesn't require a full restart.

Not answered - in terms of Intel actually fixing their chipset/driver

But I don't blame them, they have been useless at this for years. /sigh

I would suggest that if you are having this issue that you work with your OEM since this kind of issue sometimes has SBIOS dependencies. I have not seen this issue with the systems I have available for testing so it very well may be SBIOS related or some other factor related to the build on your system.

Three different OEMs are affected, and the problem only occurs with Intel's latest driver (i.e. the driver before this worked fine). That would imply a correlation of zero between having the issue and laptop manufacturer thus making it a very illogical approach in finding the bug. Plus it's inefficient, since an OEM isn't going to look into something until enough users complain, and then you'd have three teams duplicating their efforts. Furthermore, the most obvious first step would be to look into what changed regarding standby between the two releases, which would require looking at driver source, which Intel is most qualified to do.

OTOH, it's understandable that Intel would have difficulty investigating a bug they can't reproduce. Personally I'd just wait and see how many more complain of this issue as the update trickles down to the masses and see if there are any commonalities between the aflicted. Plus, knowing my OEM, suggesting that they spend money fixing something in a laptop they already sold is remarkably futile.

Same issue on Acer Aspire 1410. No problem until the Intel driver update (8.15.10.2021) which I performed last week - since then, the problem occurs frequently on awaking from sleep and/or hibernation.

I greatly appreciate the workaround (assuming it really will work) but it is not a solution, as most users will not find their way to this forum - indeed, will not even realize that the problem is associated with an Intel driver update.

As for the chance that Acer would do something about this... maybe in an alternate universe.

Simple simple simple solution. Discovered this morning after finding a garbled screen.

Remove the power lead (your screen will flicker and restore itself) then replace the power lead. Obviously do the opposite if you initally wake on battery.

No need to go in and out of sleep as previously suggested. Clearly this chipset has issues relating to going in and out of sleep with different power sources.

For the record, removing / replacing (or vice versa) does not work for me on the Acer 1410, but the sleep / change power / wake solution workaround does work.

I am having the same problem on a Gateway NV5814 laptop running Windows 7 Home Premium. This NEVER happened prior to updating to 8.15.10.2021. Since the "update," most of the time when I close the computer without shutting down (don't know if this is "sleep" or "hibernate" mode) the screen is garbled when I return. The computer is on electrical power when I close the lid, though sometimes I might unplug as it's going to sleep. I always plug in before turning the computer on again.

I don't believe "simply" unplugging and replugging (which I haven't tried) is a solution. A software update should not dictate our physical interaction with our machine. It may work--I haven't tried it--but it's not a solution; if an update to your car required that you unplug the battery cables every time you start it up, you would demand a repair. I demand a repair to this update!

Could you possibly try the latest release for the graphics driver to see if the issue still occurs? It is available here: http://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&DwnldID=18787&lang=eng http://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&DwnldID=18787&lang=eng

Hurrumph, follow the link and get this: "The file that you are trying to download has either been moved, renamed or archived.

Please go to http://downloadcenter.intel.com/ http://downloadcenter.intel.com and choose your product to find your download."

Follow that link and get the same thing again.

Definetly seems to be an issue there,, thanks for pointing it out, I will have it fixed. In the mean time, you can use the "zip" version of the driver. Just extract it and run setup.exe.

Here is the link: http://downloadcenter.intel.com/confirm.aspx?httpDown=http://downloadmirror.intel.com/18788/a08/WinVista7_15169.zip&agr=&ProductID=&DwnldId=18788&strOSs=&OSFullName=&lang=eng http://downloadmirror.intel.com/18788/a08/WinVista7_15169.zip

Attempted install. Got "This computer does not meet the minimum requirements for installing the software."

Acer 1410, 2 GB RAM, lotsa free hard disk space, Win 7 Home Premium.

Enough. I'll let others play guinea pig for a bit.

You probably have an ACER modified driver installed that is preventing overwrite. There's a way around it if you want to try.

I just searched for and installed the 64-bit version. I had to uninstall it in safe mode since it left me with a completely black screen after installation, and didn't resolve after a hard reboot (i.e. the login screen never became visible). When I have more time I'll try again and watch the installation a bit more closely.

Edit: I reinstalled the driver a couple times (once with the installer, again after extracting the driver and using Window's Driver Update) and had the issue both times. After the installation the backlight goes out, and the screen is entirely black (tested with a flashlight). Upon reboot the backlight comes back, but the driver never displays anything on the screen. It actually reminds me of an issue the linux driver had a while back, where TV-only output was favored despite not being connected. In any case, this isn't pertinant to the topic at hand, unless there turns out to be a link between the two problems.

Hello! Same problem here with an Acer Extensa 5635Z with 1 month of life (bought 30th Jan 2010). O.S: Windows 7 Ultimate 32bit. Tried both the drivers for the GMA4500, the Intel latest one, and the windows update one. The problem occurs randomly after coming back from the suspend mode. Have to restart PC to get it working.

I post some images of the artifacts. I read around that someone resolved changing defective RAM. What to do?

The common theme on this thread seems to be ACER. I would strongly recomend everyone with this issue on their ACER system contact ACER or the place where you purchased the system to get support.

I have a Toshiba laptop - and I was the original poster.

I have installed the updated drivers, linked above, but am not sure if they have helped. I am now in the habbit of waking my laptop (sleep and hibernation) with the mains power disconnected. Then once, the desktop has loaded, re-attach the mains power - if I want to use it. My screen now does not come up garbled. But I need to try waking it on the mains to see if the issue has actually been resolved.

At this point, I can live with the issue.
