your IBM may or may not have an HDMI connector, or an S port. It depends on how it was configured, you may need an adapter cable, or you may not be able to do it at all.
Why don't you post some pictures of the available connectors on the laptop? The forum members need to see what you are looking at.
Look in the user manual, or tech manual for the laptop, this can usually be downloaded from the manufacturer. The manual shows what is available, or what options can be installed.
