I officially messed up all the screws and now I can't get further!
I had a tough time getting one of the battery screws out - the tri-slotted ones (who ever heard of tri-slotted screws?!?) and stripped one of them. I covered the rest of the logic board carefully and cut a new slot in the screw head with a dremel - VERY carefully. worked like a charm.
I'm removing the logic board from a MacBook (13-inch, mid-2009) i.e. Penryn, and at this step there does not seem to be a temperature sensor at all as the photo on this page show for Alternate Layout: Santa Rosa and Penryn. The connector is there on the logic board but there is no cable and not sensor to speak of between the heat sink and the fan, as in other models.
