[TriLUG] How to read IBM Thinkpad Model & Type?

[Liyun Yu]

I was trying to find out what was the difference
between two IBM Thinkpad X41 Model/Types. I searched
the IBM web site and Lenovo site but did not find
the easy way needed to compare these two:

IBM Thinkpad X41 2525-F6U
IBM Thinkpad X41 2528-FRU

I can find the details of 2528-FRU but could not find
details about 2525-F6U.

Anybody knows a way of how to compare them? Any links?

Thanks,

Liyun Yu
