Having problems with your HP PC Laptops ?

I have an HP 450SX4 laptop and the battery was getting very hot and wouldn't hold a charge. I bought a new battery that seemed to hold a charge, but was not showing on the laptop (battery level). Now it does not seem to hold a charge. Can you get a pin-out for the charger connections on the battery connection or a website to find the same? Thanks.
