The purpose of this spreadsheet is to provide a guide to the compatibility within and between the ThinkPad T Series models.
The spreadsheet contains information that can be used to highlight the compatibilities and differences between ThinkPad models when doing transition planning and/or to build an initial software image.
This package is NOT intended to be a list of the latest levels of the software drivers needed to build an image. Although it is current as it is being created, it will become out of date over time.
For the current list of the levels of the latest software drivers, see the support page on the IBM ThinkPad web site at:
