Unknown device ACPI\LEN0068

Installed a new T420 with Windows 7 Enterprise and loaded drivers from Lenovo support site

One Unknown device remains in Device Manager

Hope someone knows what device driver this refers to

It was the Power Management Driver (not Power Manager) and using Lenovo System Update for Windows 7/x64 solved it

Mine is fixed now too, thank you. I didn't see any other posts here and I just wanted to make sure you know your two were helpful to me. Thanks again, mt420.
