My family has an old Dell inspirion 1545 laptop sister used it for school many years ago and it is locked and she does not remember the password. We've tried for days with no luck and I guess too many attempts on login now when it restarts it doesn't boot to the Windows page it boots to a gray and white page. And also the f keys or none of the keys seem to work or lit up . It's been several years since used and she has no info or past papers on it. what do we do please help
