How to factory reset hp tx1000 entertainment notebook


My dad gave me a tx1000 that he bought from a friend a couple years back. He never used it, so I need to do a factory reset. All I have is the computer and cord. When I try to press F11 when I reboot it, it just continues to the log in screen. Do I need a disc to factory reset, or is there a different underlying problem here? Thank you for any help you can offer!
