Hello,
New to the forum, and fairly new to mac's. I have 2 b+w G3 power mac's that I bought for parts, neither had hard drives, or memory, one had a 300mhz and the other had a 350mhz, tried using the powermac with the 350 installed and no matter what I did it wouldn't recognize a hard drive, so I figured there was something wrong with the motherboard, so I installed the 350mhz into the motherboard that originally had the 300mhz processor, figured it's sort of like an upgrade would be, added some memory and a Maxtor 40gb hd and installed OS 10.2 and I have 2 problems that I can't seem to figure out...first no matter what I do I cannot get the computer to go to sleep, the screen will go to the screensaver, but the computer stays running at full tilt, even if I manually put it on sleep, the screen will go dark, but the fans and hd keep on going.
Second, the computer is only recognizing 300mhz not 350mhz. Would this cause it to not go to sleep?

Welcome,
the fans are not going to stop even in sleep mode in a B&W G3 Power Mac, at least that is the behaviour of the one I have near me. The hard disk goes to sleep here. You'll also notice that the light in the power button does not change to amber/light orange like it does under Mac OS 9 and previous OS when the computer goes to sleep.
The CPU being recognized as 300 MHz could be an issue with the pins in the motherboard that expecify the speed of the CPU. If you see a 'void warranty if seal is broken' adhesive label in the motherboard, they are there. People use to change them to overclock the computer, maybe you need to move them to 'tell' the computer as being 350 MHz… but I am not sure about that being honest.

Thanks, I didn't realize that the power light wouldn't change to amber like in OS9. When you put yours to sleep, does it at least quite down, or does it sound the same as when you have it up and running? Because mine never quites.
I assumed that the power light would dim and pulse like my eMac and Powerbook, and quite down. But my light stays solid green.
Maybe I should put the 300mhz processor back on the motherboard and see if that helps.

My old G3 still sounded like it was running when it was asleep. Apple never really fully supported the B/W G3 sadly under OS X. They never resolved a conflict between the G3's and certain Firewire CD burners that was not present in 9 but present in X.

I have a B&W G3 and a MDD G4 here, once you put them to sleep, the MDD G4 is silent, the B&W G3 isn't. I guess it is the usual behaviour with the B&W G3.

you have to change the motherboard jumpers when you change the cpu or it wont run at the correct speed.
go here: http://www.xlr8yourmac.com/G3-ZONE/yosemite/OC.html for the settings & details 
And yes, deep sleep was never really supported in the B&W's firmware, but otherwise will run OS X just fine
