I followed Matt's reset instructions and it worked. Thanks BTW, I found the same info on the Apple Support Communities site, with more detailed info on Resetting the SMC (system management controller). One difference I noted: Matt said hold down power button for 30 seconds. Apple said 5 sec. For the record, I did 30 seconds. It did more than remove that battery service light. My fan used to also run excessively, and now that is fixed too! Worth checking out: http://support.apple.com/kb/HT3964
How brilliant! Great pictures! But where did you buy the new logic board?
