I got this laptop for one dollar.
Something was obviously taken out of it. My guess is the battery, but I've never really dealt with laptops before. It's a Compaq Presario 1245. I'm really not too keen on buying a battery for something I don't even know works. Can I use a compatibile power supply to at least see if it works? Can this be done without the battery?
