Bought a Gateway 400SD4 laptop in good shape and did preventative maintenance: cleaned the heatsink and replaced the thermal paste. Has a Pentium 4 running at 2.4GHz, 512MB RAM, Windows XP Home SP3, 40GB HDD, CD-RW/DVD-ROM combo, floppy drive (something that didn't come standard on Pentium 4 laptops), 1 CardBus slot (has 2 doors for inserting a bigger CardBus card, like Xircom modem and FastEthernet cards or something similar to that nature), VGA, Parallel (printer), modem, Intel FastEthernet, 2 USB, FireWire 400, and audio in/out jacks/ports, ESS Allegro ES1988 PCI sound, and either a 14.1" or 15" TFT Active Matrix display. Main battery is flat and refuses to charge and the clock battery is an ML1220 (rechargeable coin cell), which is rather odd, however, no charger came with it, so I improvised and decided to use my ASUS X54C's laptop charger and it works perfectly fine, even my HP Pavilion N3350 doesn't have a charger and the ASUS charger does a good job.
