How to persistantly disable PCI Express graphics adapter? RRS feed

  • Question

  • I have a laptop with two graphics cards, a PCI Express ATI HD 5xxx series and an embedded Intel HD graphics adapter.

    I never want to use the ATI card because of the poor color depth and just want to use the Intel HD adapter. Unfortunately, the sleep functionality of the laptop is not enabled unless the driver for the ATI card is installed, so simply uninstalling the driver to disable the card doesn't work.

    I have disabled the ATI card in device manager but after reboot, it is re-enabled every time.

    How can I persistently disable a graphics adapter while still leaving the drivers installed?

  • How about if you just physically remove the ATI card?

    You don't mention the laptop manufacturer, but have you tried their tech support or forums for an answer to why sleep mode doesn't work with the Intel graphics chip?

  • thanks for the reply, it's a brand new HP tm2t (2100).  The Intel card does suspend correctly when the ATI driver is installed and disabled (it just won't stay disabled). The reason suspend doesn't work I believe is that the ATI card is detected by windows as a "Standard VGA Graphics Adapter" when the driver isn't installed but it doesn't know how to stop and resume so it disables the feature.

    I'm loathed to take a screwdriver to my brand new machine, I'm surprised that disabling a device in device manager is not persistent, and that there is no software solution...

    I'll give the HP support forums a try as well.

  • I was mistaken about there being two cards, it's just that the ATI card shows up as two cards in device manager. Still trying to figure out how to disable one of them, or get it to work correctly...

  • It looks like, for some reason, both drivers were installed. The latest are here:

    You could uninstall both the Intel and the ATI drivers, reboot, and see which one Windows finds as new hardware. Or use something like Belarc Advisor   http://www.belarc.com/free_download.html   or SIW http://www.gtopala.com/  to find out which you really have.
