Hi,
My computer is working fine except sometimes I cannot make it
go to sleep. I hear a noise that seems to come from the fan, I assume is the fan because the computer works perfectly fine.
The sound is like a motor been tired a constant sound like
and rrrrrrr..rrrrrrr.rrrrr.
Any suggestions where the sounds it can came from?
Thanks,
Mia
Is this a good question?

I'm not too farmilier with this mac, but it looks as if it's overheating (Or at least thinks it is). Have you removed the processer heatsink cover, and checked for leakage from the Liquid Cooling Unit? (This was only there in later dual, and quad models) try remoiving the cpu's, and cleaning the dust from the attached heatsinks.

DO NOT REMOVE THE CPU's unless you have the fan recalibration software only available to Authorized Service Providers.
There's software needed to re-calibrate the fans? Apple can't seem to meke anything easy on these machines, can it?
I've been trying to get this software for 3 years.
Me too! If anybody has access too this software drop me a line: info (at) re-mac.de
The fan syncing software is on the original system installation disk. Start up holding down the "D" key.

Hi
This is Ejaz. The Mac will not go to sleep and make those sound,if you are using 3RD party memory. Because on some memory chip,sleep controls only works only PC platform not on MAC. Mind you not all memory are totally compatible with MAC.
Thanks

You reset PRAM and NVRAM for setup default the sensors
turn off mac g5
turn ON mac g5
before you see gray screen down
holddown COMAND + OPTION + P + R
mac g5 is startup
and you wait ear 2 sounds of startup
now holdoff key COMAND + OPTION +P +R
the g5 setup now on default
when start up
go system preference
go energy saver
go nergysaver/option
go velocity of procesor and setup slow
with this your g5 work silence and fine

Do you have it closed up or have you removed the plastic cover? Is it off? Has it ever been taken apart? The sound is coming from a fan, we just need to determine why. How are you trying to put ti to sleep?

I clean my computer in a regular basis, the plastic cover is in. I don't have apple care
anymore. I think shouldn't be a big of a deal to change the fan if I decide to.
When I try to make it sleep is from the apple menu bar
Apple /go to sleep, for seconds seems that is doing it. but a little click like
a switch. make it turned it on again.
Thanks for your reply.

Let's check some settings.. Go to System Preferences - Energy Saver and check the bar next go to Desktop & Screen Saver and check the Start Screen saver bar.
