Been lurking on this forum to find answers to random questions I have ran into over the last few years. Finally I have a question I can't seem to find an answer to... I was recently at my parents place for a visit and rummaging through the closet came across their old Mac Classic as well as a pile of floppies with one labeled "Neil's Ideas". Since I was about 7 when we got the computer back in '91 I am pretty curious what grand ideas that disk holds. After plugging in the computer and turning it on there was nothing on the screen or noise from the fans but a faint clicking noise coming from the general area of the power supply. I did a bunch of research to see if I can find anyone describing a similar symptom but came up empty so I opened it up and found the battery on the motherboard had leaked. I cleaned as much of the gunk as I could off and put it back together sans battery (i read that it should still boot without the batter, is that true?). Same result. Nothing on the screen and a faint clicking noise. Seems to come from the rear half of the board that the power supply is on. Cant seem to pinpoint exactly where. I ran it with the back case off and also noticed that the dust twitches in time with the click, not really sure what that means.... I finally got a reaction out of it after figuring all was lost and resorting to a firm slap to the side. After slapping it the fans spin up and the screen comes on with single pixel diagonal lines. There are faint noises from the HD but the computer never boots or gives a sad mac, ? disk, or any other sign of life. Long story short what I am hoping to get out of the Mac Rumors best and brightest is what is wrong with the computer that would solve it by whacking the side? I assume hitting it is not a very good solution long term. Also what might be getting it stuck on the gray/diagonal line screen? I am guessing my battery sludge cleaning was less than adequate. I plan to run it through the dishwasher after dinner/dishes tonight as that seems to be a common suggestion online. Another note, I do not have a keyboard cable so I just have the mouse plugged in not the keyboard. Thanks all for any help!
