    I just got a T500 (running Xp Pro) and am having an annoying issue with the display resolution. I have it set to 1680x1050. When I close the screen lid the display is disabled but switches into a lower resolution. When I open it, it switches back to 1680x1050 but the icons are all misarranged and open windows are smaller, just as they would be if you switched to a low resolution and switched back. I'm running no external monitor and am using no docking station. I have the power settings set to never shut off the screen, to never go into sleep mode when I close the lid, etc.

    I read something online about this model having two video adapters, so I thought it may be switching to the other one to conserve power or something like that. But in the ATI "Catalyst Control Center" program it only shows one adapter (HD 3650 DDC Display). Any ideas how I can get it to stop switching to a lower resolution when I close the lid?
    Thanks,
    MikeSebring

    If you using Windows XP the operating system should not switch between the two display adapters because you can do that only under Windows Vista. That said go into BIOS and make sure you have the Dedicated graphics option selected. That practically locks the display adapter to being the ATI graphics card. You can also disable the option that the OS can switch between them, because Windows XP will not do that. After you made these changes try again if it helps your problem.


    By the way, does your computer enter sleep when you close the lid or have you configured another action to the lid closing?
