What is waking up my iMac G5 PPC 2.1GHz, OS X 10.4.11 ?
I have been having this problem for a while: my iMac occasionally wakes up if I swich on a desklamp, or sometimes when I just walk by the computer.
I would like to know what could be the reason for these wakeup events.
Here is a list of events written in the Terminal application when I wrote "syslog":
"

Could that info give any idea about the cause for odd wakeup events, and/or what to do to fix the problem, or to find out more info?
This computer doesn't use any bluetooth or wifi peripherals, and the bluetooth and wifi are turned off. The computer has attached the original Apple usb-keyboard, a thirdparty usb-mouse, one usb-2 extension cord into which I have added a usb-2 router for 4 usb devices, into which I often attach an Epson scanner and/or a usb-memorystick. Then I have attached one LaCie external harddrive over firewire 400 cord, which is the original LaCie-made cord with anti-magnetizer (the small magnet in the cord). All of these peripherals should be in good condition, and they do not cause odd wake ups in my other iMac (G4 PPC).
The computer is attached to internet over an ethernet cord (cat6 -standard cord) but the cord doesn't go straight to the cablemodem, it goes to an ethernet router that is located very close to the computer desk.
