[QUOTE="chscag, post: 1334184, member: 46727"] The concern is the fact that no "chime" (bong) is being sounded when it attempts to boot. That could be the sign of a hardware defect. I really haven't heard of any problems with logic boards on the older MacBook models, usually the failing logic boards are on the older MacBook Pro models. I'm thinking that the machine has a failing power supply module that sometimes works. Why don't you go to [url=http://www.ifixit.com]iFixit: The free repair manual[/url] and see if you can find the instructions for changing out the power supply module on your MacBook. Also check to see if they have them in stock. Of course the problem could be something else. Unfortunately a 2007 MacBook Core Duo is not worth very much and certainly not worth spending a lot of dollars on repairing. [/QUOTE]
