Dead iMac G3 (Summer 2001)
I acquired an old G3 iMac SE and wanted to attempt a repair on it, or even just learn more about the inner workings. It had no RAM when I got it and the only sticks I have on hand are PC-100 (32 Megs) and PC-133 (64 Megs). Other than the RAM, everything else appears to be standard. Here are the specs, based upon the Apple site, per the serial number:
Order no M8510LL/A—Graphite
Processor 700-MHz PowerPC G3
Level 2 cache 256K at 700 MHz
Memory (PC100 SDRAM) 256MB
Hard disk drive1 60GB Ultra ATA
Optical drive CD-RW
Graphics support ATI RAGE 128 Ultra with 16MB SDRAM
FireWire Two ports
USB Two ports (12 Mbps each)
VGA video mirroring Yes
Fax modem2 56K V.90
Ethernet 10/100BASE-T
With only the 32 Meg stick in, the machine will not boot up at all when pressing the power button. I have observed a green LED on the mainboard, near the RAM slots, lighting when I press the power button. At the same moment, I can hear the faintest whir sound begin and then end. The LED remains on until I press and hold the power button once more.
I am in the process of downloading the service manual for this model from a friend and plan to delve a little further into the innards once I have the manual. If anyone has any suggestions for trouble-shooting or problem solving in the meantime, I would appreciate it. Thanks!!
