Duplicate upload of the Sony VAIO MBX-126 archive tied to Quanta project JE5, 1.02 MB in RAR format and identical in size to the other copy. The name lists no laptop model or revision, leaving the exact contents unconfirmed, though such packages commonly hold circuit diagrams. Those are used to check power rails, identify components and test points and follow signals between the EC, chipset and power controllers. Open with any RAR tool, and confirm the JE5 code, MBX-126 label and revision printed on the board before working from it.
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.
