Compressed file for the Sony Vaio PCG-61611, a notebook whose motherboard was designed by Quanta under the project code NE7. The name includes a revision marker but no actual revision value, so check the board silkscreen before trusting component references. At 1.25 MB it fits a full schematic set, used to trace rails from the DC jack through the charger to the CPU and to find test points. Open it with WinRAR or 7-Zip, and keep in mind that Quanta often reused project codes across related revisions.
