Hard drive or processor...

H.S. Senior, TiBook 1Ghz/60/1Gb Just bought a lightly used tibook had no obvious problems. Used for 2 1/2 months worked perfectly. superdrive ceased to function properly so i carefully opened it to prep for replacment with DVR-K05. DVR got lost in shipment, so i had to put the old drive back in. Rewired exactly how i found everything, tucked everything in its place, started it up, and heard normal boot sound but immediately went to sleep. Tried to wake it up, but no luck. Shut down, reboot, and right after my finger left the power button, i hear this god awful screech. Now, no boot tone, hard drive seems to function normally, but NO processer activity noises, only fans and a hard drive. paid $800, and i'm fairly sure this is a processor/logic board problem. any advice or suggestions greatly appreciated.
 
there's no such thing as a "processor activity noise". i guess what you really killed was the harddrive...
 
I agree with Fryke, sounds like the Hard-Drive is shot, or something is pressing against it prevented it from spinning correctly.
 
if i'm not mistaken, isnt the startup tone recorded outside the hard drive somewhere? if it were the hard drive, isnt there some sort of a exclamation folder that tells you the computer cannot find an OS. but i might be wrong.
 
...which is probably why a logic board problem is suspect. Even if the hard disk was shot, you'd get a startup tone and an unhappy Mac icon.

Have you tried disconnecting the DVD drive?
 
You are correct, in that the Start-up sound is not on the HD. From my experience, even if you HD is bad, and making grinding sounds, you still may not get the start-up chime, or any indication on the screen. He could have a combination of two problems, logic board and HD.
I had a G3 PB, few years ago the logic board and HD went. Although in my case I got a series of three beeps, then system would turn off.
 
now there is a new bit of information in my disaster. everytime i connect the ribbon (the longer one which supplies power to the lcd) from the DVD drive to the board, the fans start for just a moment and there is a wind-down sound coming from where the power supply plugs in, even when the battery is out and power supply NOT plugged in... which also points to a bad PMU... does the PMU have anything to do with the initialization of the boot partition?
 
even MORE fun stuff. I have a cooling pad that i use under my PB, i plugged it in and it runs no prob... when the logic board goes out, doesnt the whole thing go?
