Decrypted copy of the Sony VAIO VGN-C22CH schematic archive for Foxconn-made motherboard MBX-163. The decrypted tag implies that the password or copy protection on the PDF has been removed, so it opens and prints in any viewer. At 857 KB it matches the original package in content. Use it to measure power rails, follow the startup sequence, locate test points and find the part shorting a rail. Check that the board in hand carries the MBX-163 marking.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @generalschematics. Enginerys does not host this file.
