My MBP hasn't worked in forever, though today I just happened to attempt to turn it on not expecting it to work.... IT DID! Asside of being very slow, it works. The only thing I had to do is change the date and time. I haven't checked the internet, though. (I'm on my iPhone now.) My internal hard drive is at 368.25 GBs with an original capacity of 498.88 GBs. I don't want to do anything with my new iPhone on it because the problem might not be totally fixed. Should I take it in to have it checked out?
