my frend was going to throw out a dell inspiron 6400 laptop because he lost the harddrive(dontask) so i said ide take it and i had a spare hardrive laying arond. so i poped it in and installed windows xp but the laptop is ment for vista so nothing works. built in wifi bluetooth and the modem. and when i try to put windows 8 on it it says i need xp service pack 3. and i cant get internet to updte that. i tryed the ethernet port but that doesent work eather. i was looking for some drivers for xp.
