I have one of the series, mine is 2621, very similar tho. Once you close the lid it becomes stand alone cd player. Other than it's big and bulky it's pretty nice design. Mine has a night lite above the LCD where a modern webcam is. Crucial memory said my max is 512 ram. One thing I like a lot about the Thinkpad it is that many comes with miniPCI slot. Usually used for the modem. I take out the modem card and put in a cheap Wifi card and find a way to run antenna out. Mine is also only 433Mhz with 256mb ram. Run XP pretty well until I update to the modern updates such as sp3, ie7-8, etc.
Does yours look like one of these?http://i33.tinypic.com/2ah8wt4.jpgAdmin edit
