How to disable ATI Radeon 3400... for good!
Posted on 2011-05-10
I've had ongoing problems with an ATI Mobility Radeo 3400 series card on my Lenovo T400. Now and again, the video card (or driver, who knows?) fails, my mouse freezes, I get a BSOD (black, not blue), and I have to reboot. It used to be that the screen would just go black momentarily and then recover (with an display driver error message), but lately, it's gotten worse and the only solution after the screen goes black is to force a shut-down and reboot. That's the bad news. The good news is: If I disable the ATI card and go with the Intel card, I don't have the issue. I'm not gaming on the thing, so this is a fine solution. However: There's one small problem:
Even though I've disabled the ATI device in device manager, it keeps re-enabling post reboot. I've disabled it, I've uninstalled all the software, but the blasted thing just keeps coming back to haunt me. So here's my question:
Short of opening up my laptop and performing an ATI-ectomy, how can I permanently disable my ATI Mobility Radeo 3400 Series device.
