How about using another keyboard?
So earlier today, while my dad and I were working on my science fair project, the 'i' key broke randomly. A bit stupidly, my dad thought that restarting the computer would fix it. We didn't know that the entire diagonal row wasn't responding (8,I,K,Comma,Alt). His password ends with -888, so we can't get back in. This is incredibly bad, because we need that computer (paint shop pro) for my science project, and he leaves late tomorrow for a huge meeting. He may be able to find another computer, but not the exact same one (so they could put the hard drive in) and not with his work stuff on it. Please help! Is there any way?
