Not sure if this'll help on your particular laptop but, Windows XP and up can use a thumbdrive (USB 2.0 is best) as additional RAM. Maybe not as fast as the real thing but, faster than the Page File used by your HD. A 4GB thumbdrive gives you that much more memory. Installing a new TD should automatically bring up a menu asking you if you want to use the thumb drive as a performance enhancer. It might help.
BTW, in the stock version, there isn't even a port at Truk.
