I'm currently attempting to charge my 2006 MacBook and am having no luck. The charger is functional (I've tried it on my brother's computer and tried his functional charger on mine) but no light turns on and the computer doesn't recognize that it's attached. coconutBattery only reaffirms that a charger is "not attached" and the battery is not charging. Any ideas? As in most cases, I'd prefer not to take it to the shop if at all possible. Thanks!
