Fully working XP system. I have installed XP Pro SP3 with all drivers. Main battery and CMOS battery do not hold a charge, so any time the computer is unplugged, the time must be set in the BIOS. The left click is loose if clicked on the far left side. Works fine, but you have to click it from the middle or the right side to keep it from getting loose. Has NVIDIA Quadro NVS 140M graphics, which should be good for a majority of games prior to about 2002. 2.5GB of RAM, 60GB HDD. No power adapter included. I can help you find one if needed. 1440x900 display, great picture.
