RAR archive of 1.69 MB for the Sony VAIO VGN-FE series on the MBX-149 mainboard with project code MS10. The project code differs from another MBX-149 package marked MS13, so the board may have been built in more than one version and the right file depends on your PCB. Expect schematic pages for tracing the charger, CPU regulator and graphics power, plus component references for locating parts. Compare the board marking and title block revision carefully before taking measurements from these sheets.
