Hello i have an apple mac g4 quicksilver dual core g4 processor with 1.5 GB of ram and a 111 GB hard drive with latest version of leopard, i will put the mac to sleep and will come back to find that i can not wake it back up! i always have to restart it after i put it to sleep.

I know that corrupt video drivers will affect standby/hibernation on a PC. I wonder if it would be the same fo a Mac

Is the firmware up to date along with the software? Any warranty left on the Mac?

Your going to need somebody with better knowledge about Quicksilvers than I. Try a forum specifically for Macs like this one here.

i am a person who works on computers so i get a lot of people who want there files backed up to another drive so they can install windows 7 so i figured out yesterday that if i take out the 2nd hard drive the computer goes to sleep and wakes up just fine.

I use the mac to move files beause it is easier to access and change out drives and it is faster.
