Me and my brother were going through our grandmas storage building and found her old iMac. I pulled it out and I have been trying to get it to start but it won’t turn on. Any ideas would be helpful because I’ve always wanted to look around on an old computer and now I have the chance. I have it plugged in and the original keyboard and mouse that they got. Thank y’all for any help you can give.
First thing to do is replace the PRAM battery. It’s a 3.5 volt 1/2 AA. You can see it in the teardown on step #11 of this guide, it’s purple and black (the replacement does not have to be the same color). iMac G3 Model M5521 Teardown
