So i noticed my delete key wasn't working so i closed my laptop and opened it again and then i couldn't log in bc more keys werent working so i restarted the mac and now i can't log in because the keys are typing by themselves and acting retarded and some are t working and im getting so frustrated! Im on my phone right now.. It's my school laptop so i really don't want to take it in because they might charge and i can't afford it!!! WHAT DO I DO????
