on no, my 17" g5/imac 2.0v2 is getting jiggy on me!
#1
so here's the situation:

17" g5 imac 2.0 v2/10.4.7/9mos old refurb from online apple store

i keep my imac running almost all the time. when not in use, i put the machine to sleep.

three times in the last 4 weeks, i've come back to my desk to find the machine off, there is no slow blinking light on the lower right corner designating the machine is asleep. there is nothing.

when i attempt to wake the machine, the screen does not light but the rear upper fans do start to blow. when i continue to try to wake the machine, all i get are the fans blowing.

i have attempted to control-apple-escape to force quit but nothing appears on the screen.

i have to unplug the machine from the wall socket, then re-boot. when i re-boot, i do get the "happy bong" and there are no alerts or dialogue boxes explaining the shut down.

anyone want to be kind enough to venture a guess as to what might be going on and how i can either ascertain the nature of the problem or suggest a solution to my travails?

up until now, i have been VERY happy with this machine.

thanks in advance to any and all who care to share.

be well

What do you have external wise hooked into it? That could have something to do with the sleep issue.

often i have several external hard drives via the fw

but lately, i have had ONLY the printer via usb and a lexar 6-1 card reader via usb. the keybd/mouse is also usb.

all of these 3 shutdowns have happened w/o any of the ext hard drives.

any other thoughts?

thanks again for sharing

be well

Call Apple. You're under warranty. Did you do that video card hack that we talked about a while ago? If so you may want to undo that before sending it back or taking it in.

Disconnect the card reader.
