[QUOTE="Kevriano, post: 525632, member: 18605"] I assume that we are talking the iMac with the dome base and lamp design and that you have no discs, so first to answer the memory question, the slot is for expanding the ram, it should have at least 256 in built, so unless someone went to a lot of effort, you should have that. When you connected the iMac to the powerbook did you use Target disc mode? You need to for it to show up. If you are getting sounds it's unlikely to be power, so try a few things first. Reset the PRAM but starting up holding command, option, P and R, wait for 3 "bongs" then release. Then try this. Restart holding Command, option O and F. If it gets to a whitish screen with text type the following (the hyphens are important): Reset-nvram and then hit return set-defaults and hit return reset-all and hit return. After that. Boot into single user mode by starting up and holding the Apple and "S" keys. Wait for the text screen to load (if it does!) and then, depending on the OS it has you need to type (again exactly as here) fsck -y (for anything pre Tiger) fsck -fy (for Tiger) If you have got that far, and it has run the text, see what the answer it gives is, You would like to be seeing "the macintosh hard drive appears to be ok" if it doesn't show taht after trying it a few times, try and report the message you get back here, and maybe we can aid more then. See if any of that helps first. It could be an internal battery issue, but I haven't come across that fault to know for sure. [/QUOTE]
