I have ThinkPad T500 which is originally installed Vista and then converted to XP but not successful. After reinstall back to Vista from XP, an error message " Can't open ACPI ATK0100 Kernel Mode Driver ". I try to download some ACPI driver from the web, but not good at all. Please help me to resolve this problem. Thanks.
