My dad bought this for me overseas and I'm not from the US so I can't actually call support. My laptop haven't been used for a while because I know it's not functioning properly and when I turned it on again, it won't boot. There's just the Dell logo with press f2 and f12 (but they won't work too) and then the screen goes black with "enter system password" and I have no idea what it is. I remember getting this laptop fixed but the technicians can't get through this system password thing. How am I going to get the password? And I get through this, will I be able to restore it to factory settings? I'm trying to format my hard drive. Thanks
