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

[idata]

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.

Hello, I want to join the discussion because I have the same problem on my DELL Inspiron 11z. This is not an Acer problem, it is a problem with the GMA 4500 video driver. My computer looks like this:

• Dell Inspiron 11z with BIOS version A04
• Graphics adapter: Mobile Intel GMA 4500 MHD with driver version 8.15.10.2021
• Windows 7 Home Premium 64 bit

When the computer resumes from hibernate mode, the graphics sometimes looks "scrambled". I have attached photos to describe how it looks. I believe this is not a hardware defect, because I have run all kinds of hardware and RAM tests with the built-in Dell test application. I looks to me like the video memory is not correctly initialized after hibernate. However, the computer itself runs fine - applications are not affected. The problem is cured when I reboot the machine. However, it is very annoying. I already found out this:

• Problem never happens after reboot
• Problem never happens after resume from standby (suspend to memory)
• Problem sometimes (50%) happens after resume from hibernate (suspend to disk) and is cured by a reboot

The workaround described here seems to be working for me. Happy to know that my computer is not broken! However, I hope that Intel will fix this in the video driver. I do not want to go back to an older driver release, because I want to use Flash player 10.1 with video acceleration.

Update: I run a Memtest and everything seems to be ok with RAM.

Definitely it's a video card problem, maybe related to O.S. system (Win7).

At this point it's an Intel job! Thanks, A.Colella

Add me to the list of people who get a black screen....

HP G60t-200CTO

Windows 7 64 bit.

I uninstalled the previous intel driver (8.15.10.1986) and installed 8.15.10.2086.. and got a black screan... grrr... Other older intel drivers have worked just fine so I don't agree that it's a special vendor bios issue.

Intel! Intel? I cannot hear your presence!

I have the exact same problem on my VGN-SR210D Sony laptop with GMA 4500 MHD graphics, and Windows 7 x64 OS ever since I installed the new graphics driver 2086. I thought I was the only one with this problem, screen tearing (2021) and blackscreen (2086). BTW, I'm writing this in safe mode.

I really need help. If someone can provide a solution other than uninstalling the driver, I would be extremely grateful.

The workaround is the one given earlier: put the machine into sleep, then if the power cord is plugged in, unplug it, or vice versa, then wake it up.

Two problems with this: 1. if you are not near a power source. 2. The thousands of users who are experiencing this problem but are not tech savvy enough to find this forum.

The workaround for 1, hard to remember at the time: always unplug the machine before putting it to sleep. After it's asleep you can plug it back in if you want. Try to remember to wake it up unplugged as well. If you forget and it wakes up garbled, just put it back to sleep, unplug it, and wake it up again.

I know I'm going to labled as crazy for even suggesting this.. but chouldn't Intel just fix the buggy driver?

I know that sounds a little crazy.. but it's just crazy enough to work.

Not to mention that the black scrren of death isn;t fixed by this.

I'm the original poster about this issue. Thanks for all the other posts.

I'm using driver 2082 and don't seem to suffer from the issue anymore!

[idata]

Installed 2082 using windows update. Black screen appears and the computer must be run on safe mode to see anything.

Your issue appears to be a seperate, perhaps unrelated, issue.

I would suggest using the drivers from our laptop manufacturers website - and/or contact them directly for support.

Clearly the reference drivers are not compatible with your laptop.

I just updated to driver version 8.15.10.2086 from the Intel download site: http://downloadcenter.intel.com/SearchResult.aspx?lang=eng&keyword=%224500MHD%22 http://downloadcenter.intel.com/SearchResult.aspx?lang=eng&keyword=%224500MHD%22

The problem with pluggin/unplugging the power cord seems to be fixed now. Thank you Intel for the help! I am a happy Dell user now.

Woohoo!! Glad to see the new drivers resolved the issue!

[idata]

Windows update has downgraded the driver to 8.15.10.1892 (dated 9/2/2009). This version does not exhibit this problem.

I also tried installing the current version on the Intel site but it refuses, citing possible system incompatibility.

May ask for workaround advice later, but for now the downgraded version seems ok.

I have a Gateway Model # new90 with this same problem, I won't buy any computer with intel graphics again, thi i clearly a failure on their part, just look at how they choose to deal with the issue... they send some rob u guy (yea he really is trying to rob u guys, rob you all of your dignity and dollars) to replace them with faulty products) to try to disperse us all and get us to bother someone else before more people group together and establish a boycott.

if they arn't gonna fix the issue, lets buy from nvidia or ati next time!

Robert U quit pussy-footing around and make some calls, talk to the higher ups, tell them we are getting restless and want this problem fixed right!!!

We paid for your garbage inside our computers, now make that garbage at least function right!

I will repost this message and links to this page all over the internet tonight, I suggest that if anyone else wants this issue addressed that they do the same!

News from Acer: with the (2086) driver I got the black screeen. I need to downgrade manually to get PC working. I tried both 32 and 64bit version of windows 7 ultimate without any positive result. With the new driver the pc works, but the screen simply switch off. I will wait a new driver to see what happens..
