I'm posting this in the comp.sys.mac.system group because the hardware group has little traffic, and I really need to get some answers (and my issue is system-related as well as hardware-related).
To recap my previous posts, my eMac was having trouble starting up. I installed a new PRAM battery, and then tried to reset the PMU button, but it would *not* budge (is this normal?). However, the battery seemed to have fixed the startup problem, and all was fine for hours. So I thought it was safe to add some RAM (the correct stick according to Crucial and OWC). But now the eMac shuts down instead of sleeping.* I removed the new RAM, to no avail. (I also zapped PRAM, reset NVRAM, and trashed relevant preferences per another fixit forum.)
*I had EnergySaver set to sleep the computer after 20 minutes of inactivity. I did several tests of 5, 20, and 60 minutes, and it shutdown (instead of sleeping) like clockwork at those points. I did a temporary fix by setting it to sleep *never*. But I would prefer to set it back to 20 minutes so the hard disk is not spinning unnecessarily. Does anyone have any clues for a real fix? Thank you.
