Dell order n5050 laptop

Product Name: Dell order n5050 laptop
Used Dell inspiron 15 n5050 laptop. It has a small crack on the top right hand corner of the latop, it doesn't interfere with the function of the latop. The things that's wrong with this laptop is the battery no longer holds a charge. meaning the laptop battery wont charge, but it still sends power to the laptop only when it is plugged in. You can order fit this by replacing the battery Also one of the usb ports isnt working but the other two are operational. I've spent a lot of money fixing this laptop & ensuring that it's functional for use. The mother board, keyboard, original charger & the original battery was replaced a few years ago. The laptop still runs on windows 7 & You can still update to new windows program if you want to. Serious inquiries please.
