Fuses in the T61
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 a FRU 42W7622 hoping that the differences to the 41W1487 aren't too big. The page column refers to the schematics linked to before. PTC are self-resettable fuses, it should never be necessary to replace them (in theory).
