An HP Probook 455 G3 laptop with a 1TB hard drive (that is working perfectly fine, I removed it and checked), and all the rest of the parts included, it just doesn't turn on anymore. Also the screen is cracked. But you can use the hard drive and any other parts you may be able to. It used to be a really fast laptop that I got a lot of use out of, but it slowed down over the last couple years and finally stopped working altogether just the other day.
