Location on the Planar
These pictures show the locations of the fuses on a mainboard FRU 41W1487 (14" wide, Intel graphics).
Functions
The functions of the fuses were taken from the schematics of part number 42W7622 hoping that the differences to the 41W1487 aren't too big. The page column refers to the schematics linked to before. PTC are resettable fuses (deutsche Seite), it should never be necessary to replace them (in theory).
