Windows 7 Display Problem

[zack431]

I wasn't sure where else to put this, so I decided to ask for help in the Graphics Card are as my problem probably pertains to my graphics card.

I recently installed Windows 7 and it went through without a hitch, except for some reason whenever I unplug my laptop from a power source the display becomes all screwed up; the gamma skyrockets and it looks like one big threshold effect.

Any ideas about what's wrong here? My monitor is an Intel(R) 915GM/GMS.910GML Express Chipset. I have the Intel Video Bios installed, and my total available graphics memory is 96 MB. I'm running on a 32 bit display at 1280 x 800 resolution.

Help would be greatly appreciated.

HP Compaq tc4200 Tablet PC*-* Intel 915GM Graphics Driver for Microsoft Windows Vista - HP Business Support Center

^^ it's the highest version number for the 915 chipset on the net afaik.

Thank you; I'll try that driver and see if it works.

I've not had a 910/915 to test on recently but I know for a fact that the video driver and perhaps even the display subsystem in old builds of Windows 7 would not run properly with Intel's drivers installed AND graphics chipset power saving. If you're not running RC load it clean and do NOT install any garbage drivers from Intel. Last I looked they had no drivers for Windows 7 on their web site. If you need to get drivers from anywhere get them ONLY from Microsoft here: How to download updates that include drivers and hotfixes from the Windows Update Catalog. You're virtually always better off getting your drivers here anyway as Microsoft deletes all the vendor bloat and leaves only the code required to run the device.

Were you able to resolve this problem in any way? I installed Windows 7 RC1 on my HP Elitebook 6910p and I am having the same problems with Any intel drivers I use.

Unfortunately, it's not really something that I can solve. The power saving features of the Intel driver set for 910/915 appear to be incompatible with Windows 7 when video acceleration is enabled. I heard that these drivers will help with hangs and crashes when playing video at least on some ASUS netbooks. Perhaps give them a try? http://dl.getdropbox.com/u/561353/rpeterslll.zip

I had a similar problem with my GM45 graphics chipset... but my screen started showing artifacts after about 15 minutes of uptime. Reboot cleared it, but it comes back. The WDDM1.1 drivers were just as bad.

I suggest you try the Vista drivers for it, this may or may not work. Seems like the Intel graphics are suffering a fair bit with Windows7...

I had some weird artifacting with the 965 architecture, but the Vista drivers fixed the issue... It would be nice if Intel decided to get on the ball with Windows 7 WHQL drivers... Some 1.1 drivers would be dandy.

Thanks for this. I read this.. I've had it on battery before, but never booted up from battery before and 90 % WHITE. Very annoying. Hope Intel has a fix for this. I'd been running Windows 7 RC1 on my moms puter with a spare hard drive and it has an intel based graphics card. Ran fine until I asked if my brother wanted to check it out. and thats what he got. Turned it on from battery. What exactly is the probelm there. That I have to power it from a power source first then detached from the power in the middle of it.

Yep moment I unplug it, poof the display goes all funky. totally idiotic Makes no sense to me.

Is that a GeForce Go 7300? If so try these new drivers from the Update Catalog at http://catalog.update.microsoft.com/v7/site/Home.aspx. A direct link is here:

No, it's the intel card. My Dell D820 is just fine. It's got Nvidia.. Mom's D610 however has the Intel graphics card. I've read about Vista drives so maybe I'll fool around with that. Thats how I got the scroll function to work on the D610 (touchpad). I simply used my driver for the D820 on the D610.

Same problem

I had this same problem with my Dell Latitude D610 with the Intel 915GM on board. Everytime I took the laptop off of AC power, my display would go to what appeared to be 8-bit mode, displaying minimal colors. When running on AC power, everything worked wonderfully!

I had tried everything! Then I found the solution that fixed this on my laptop. The answer lies not in Windows' power management console, as I had originally thought, or even in the bios (no options for video power management other than brightness). I was playing around with this issue again today and re-discovered the little Intel driver app that was loaded with the driver. I found it again by right-clicking on the desktop, going to graphics properties, allowing UAC to run the program and then going to "power settings" (bottom right-hand corner of the app in my version).

In that setting, there is an option for "Intel(R) Display Power Saving Technology" that was set all the way over to "Maximum Battery". I moved it all the way over to the other side to "Maximum Quality", clicked "OK", then "Apply". Then I took the power cord out of the laptop, and VOILA! - the display didn't change other than dimming to the bios' default. SWEET!

I hope this helps with this frustrating issue with Intel's chip.

Wow, that worked.

Typing right now using both the main battery and the backup. I should print that out and frame it. Well it is printed out, but I should frame it
