Which laptop should I purchase?

I'm torn between two laptops. I can get a used IBM Lenovo Thinkpad T400 laptop for $193.00. It has a few minor scratches on the outside case. I'll have to buy a new battery it. It won't hold a charge without the cord. Everything else works great. My other choice is a brand new HP Charcoal 15.6" 15-g019wm Laptop PC for $248. Which one would you choose and why? I can't decide.

Get the new one the battery for the used one will cost the difference and you will get a warranty on the new one
