need help finding a new replacement power AC adapter

[Kaitlin Kaschak]

ok so my uncle gave me his old dell inspiron 9100 laptop it has a pentium 4 desktop cpu in it. any how he lost the ac adapter a while ago during a recent move and i need to buy a replacement but have no idea how many watts i need or anything else. was hoping i could go down to my local pc parts store and buy one of thoes ac adapters that fits many laptops but it looks like the dell uses a special non standard ac plug unless im wrong any ideas

edit need something cheap and for thoes who ask reason i took this free laptop from his is i like to collect and tinker with old laptops just for fun

Try Ebay as you'll stand a better chance of getting the right one without paying much for it.
