Power Mac G5 not sleeping, and no audio on right side of any connected speaker.

Hello, I have a Power Mac G5 1.8 GHz dual core, but recently it has not wanted to go to sleep. I have also noticed that if I am using the 3.5 mm audio jacks, only the right side of the speakers or headphones work. I have heard that HP Printers might effect the sleeping so I have removed all of the printers from the control pannel. It is running on 2 GB of RAM and it has a 1 TB HDD installed. It is Running Leopard (OS X 10.5.8) Please help!

PowerMac, Mac OS X (10.5.8)

P. Just in the interest of future clarity, the G5 1.8s were not Dual Core, but Dual Processor, 2 CPUs instead of 2 Cores per CPU. 🙂

I have tried this several times. It has only worked once, but within 12 hours it started up again. Thanks for the dual processor clearity! Any other ideas?

Might be time to replace the PRAM Battery, 4 years is close to their lifespan, far less if ever without AC power, & can cause strange startup problems...

See which one your G5 has...
