Thanks for getting back to me so fast.
The Windows part is easy: It’s Windows 7 Enterprise, 64 bits.
The hardware is harder, as there aren’t very many model numbers visible. So I’ll give you a dump of everything I could find.
The computer says “T430” on the front panel (on the hinge below the display). Under the battery there’s a sticker that says “Type 2349-G5U” and a serial number, then “12/09”. That’s it. This computer has two USB 3.0 ports, a Mini Display Port, a headphone jack, a VGA connector, an Ethernet port, two USB ports (no distinguishing marks, so I assume 2.0), and a little slide switch that’s labeled with a tiny icon that looks like a computer with sound waves coming out the sides (so maybe a speaker on/off switch??).
The dock says “ThinkPad Mini Dock Plus Series 3” and has a label that says “Type 4338”. There are other labels that say things like “4338 M2N7MT7 11/08” and “P/N 75Y5730”. I think this is the older of the Type 4338 docks, as it doesn’t seem to have USB 3.0 ports and it does have an eSATA port. The ports it has are: VGA, eSATA, six USB (2.0) ports, an Ethernet port, two paired DVI/DisplayPort ports, a mic port and a headphone port.
The built-in LCD display on this laptop is 1600 x 900, and the Device Manager says that the only display adapter is an Intel HD Graphics 4000. I don’t see any signs of any nVidia hardware. I currently have an elderly (but still very good) 20" Apple Cinema display (1680 x 1050) attached to one of the DVI ports on the dock. I have just bought an LG E2342V 23" monitor (1920 x 1080) that has DVI and VGA connectors. (I’m hoping to use the digital port.) When I tried my wife’s ViewSonic 1680 x 1050 (DVI) monitor earlier today, I was able to get both external monitors to work but no built-in display, or the built-in display plus my Apple monitor (as I’ve been using all along), but not all three displays at once. I’m hoping that one of your boxes will let me attach my new 1920 x 1080 monitor via a USB port without causing the other displays to go crazy. (Otherwise I’ll just hook up the two external monitors; but I’d like to take advantage of the built-in screen if I can—more pixels are always better.)
I hope that somewhere in there is the information you need. Otherwise I’ll have to get out a wrecking bar. Let me know if you need anything more.
