now before any one says any thing I am NOT a gamer. The only real games I play are the Tony Hawk games. But I am a big BTTF fan. I am stuck at the part at Docs garage. I walked around clicked on the town square and Biff took the book. I then talked to him, bla bla bla. I did the hint it said "powerful punch" so I was like oh play the guitar and blow it out with the speaker. So I did that and I thought I saw the notebook fall out of the courthouse but it was not on the ground when Biff. Left and the only clue they gave me was talk to dad about fighting my own fights and that did nothing. Did I miss something here is the notebook on the ground now next to the speaker or not. I did it about 3 times and every time I thought I saw it fall out of the courthouse. Please Help.

Turn on the speakers before you play the guitar.

I did that then I tried it again and all marty said was i better not turn the amp any higher and I no the speaker is one b/c I hear the buzzing sound.

Make sure you talk to marty's dad and tell him your fighting your own fights. Then go over the ampflier controls and turn them to the max setting. then try the guitar again and he will take it from you, blow himself off the ground and the book is yours.
