Fuses in the S230U
Location on the Planar
These pictures show the locations of the fuses on a mainboard FRU 04Y1528. Some solder jumpers were removed before and the red wire on the bottom was added for testing.
Functions
The page column refers to the schematics called "LA-8671P" by Compal from 2012-10-04, Rev. 1A_1004A. PTC are resettable fuses (deutsche Seite), it should never be necessary to replace them (in theory). The part numbers of the 2A fuses have typos in the schematics, but they are marked with "N" on the board (1A fuses carry the mark "H").
