Hiya japamac,
The reason I didn't list any specs on this topic is because I haven't added any new software or hardware to my mac, the mac operated perfectly well before the update, i.e. the sleep function.
I have previously done an update to 10.5.8 on my mac but after the sleep issue I did a complete re-install of 10.5 just so that I could get the sleep function back.
Going back to your question as to the specs, hope the information below is what you want:
Graphics Card: ATI Radeon 9600
Not really sure what you mean by ADC Monitor, but I have an HP2310ti Monitor connected to the mac.
With regard to PCI cards, I have installed a USB2.0 five terminal card, 1 is internal which has a Bluetooth usb connected, and the four external ones have my printers connected to them.
I previously tried disconnecting all the peripherals etc but it made no difference, so was just wondering if there was something wrong with the update.
Cheers, Steve
