View Full Version : IMac G5 Motherboard, Maybe Fan Issue?

Feb 5, 2008, 10:15 PM
I looked into my issue a little
but uh
recently my IMac G5 started randomly shutting down when left unused for a bit
but that seems to have stopped as far as I have noted
Now occasionally when it goes into sleep mode it will freeze on the black screen and the fan will go crazy

I plan on buying a MBP, if the update ever comes out, and then ill just completely wipe the IMac and give it to my parents, who still use the original I mac, G3 or something


anyone know of this issue and how to fix it?

I read a certain series of I Macs were having motherboard problems, W950 or something, but mine wasnt that serial code....

it could be the psu? i have a Rev B g5 imac and the power unit stopped about 3 weeks ago. you can check if thats the problem by taking off the back and using the 4 LEDs - google for info.

if you are lucky apple has a repair extension for some g5 imacs - they replaced my power unit for free, in three days, i was very impressed.

thanks, i've been meaning to look into the repair extension, I know they had one for a different serial code of I macs for the motherboard, mine could have t he same issue

ill check out the LED thing too
