Question

 

I have installed Windows 7 on my T400 as an upgrade, but the devices list is reporting a missing driver for the "PCI Serial Port".  I installed the card reader drivers from Intel which has resolved another missing driver error but this one remains.

 

I have run the System Update tool and the ThinkVantage Toolbox but these did not find and install the appropriate driver for some reason.

 

Answer

 

This driver is part of the Intel AMT package and can be downloaded from the Lenovo support site.

 

Visit http://support.lenovo.com and select from the ThinkPad driver matrix.

 

Here is a direct link for the Windows 7 version.
