I'm in the same boat- forgot about the 2nd internal battery. I'd l;ove to know where the fuse is, as well.

Usually those fuses are located very close to the LCD-connector on the motherboard.
This has been mentioned on the forum about, oh, what, 1478 times?

Many schematics can be found for sale all over the place, several also free if you dig deep enough.
