Chicago, Astronomy & Astrophysics Lines: 27 *** Trust the Computer! The Computer is your friend! *** Recently (2 weeks ago), my Mac's power supply was fried by a power surge. I took it in to my dealer, who replaced the supply for me. The problem is this: since I got the computer back, the active screen area is much larger (extending up into the corners of the physical screen), and the bell is annoyingly loud upon startup. Since I did not have this problem before, two possibilities have come to mind: (1) My friendly dealer decided to give me some "extra," free service. This seems unlikely. (2) The new power supply is delivering more voltage than the old one did. I know the screen height and width are controlled by pots inside the computer, and I would guess that the beep could be controlled similarly. Either way, I don't really feel like leaving my Mac in the hands of this dealer again. I would like to hear if anyone else has had a similar problem, or if anyone has any ideas about the solution. If the power supply voltage is the culprit, does anyone know where the pots that need adjusting are? Thanx, Greg Hajek :wq
