anybody know the remedy for my MBP (mid 2010)?? it recently feel off my bed (but had been running well). but days later (it was on just closed and when i opened it up) there was a screen with a folder with a question mark in it blinking. i restarted it many times and still the same screen so. i took it to ifixit and they said that it was the hard drive not starting up properly, they fixed that problem (then said) but when they tried connecting to wifi a screen came up asking for a password. (they still never signed in and on the desktop like normal and connecting to wifi they never got the chance to) the ifixit guy was asking me for apple id but that didnt work and they said it was the system password and i bought it used and dont know any other passwords. is there any way to get my MBP back without that password? its a white screen with a text box and doest even say whats it asking for :/
