I reinstalled XP and downloaded drivers from IBM website for my R31. Device Manager shows OK except one which is UNKNOWN.

Properties for this unknown device show Intel 82801CAM LPC interface controller. I checked with IBM website again but I cannot find driver for this one.

Any advise what is this device and where I can download the driver?

Try the ACPI driver.

Thanks for the reply...

ACPI? is that the same as the power management drivers? I believe I have installed them but OK I will install them again.

The ACPI driver is called Thinkpad PM Device under System Devices.
