If you're looking for a schematic for repair purposes or educational use, here are a few general steps and considerations:

Read-Back/Test Points (useful for troubleshooting)

  • VCC_MAIN, VCC_IO, VDD_CORE voltages
  • SYS_RESET, PWR_GOOD signals
  • CLK_OUT/CLK_IN differential pairs
  • I2C_SCL / I2C_SDA probe points
  • JTAG TCK/TMS/TDI/TDO and TRST

2. Why “Exclusive” Schematics Are Hard to Find

  • NDA protection: Schematics are proprietary to Lenovo and the ODM (likely Compal or LAC).
  • Leaked schematics sometimes appear on repair forums (Badcaps, LabOne, Vinafix) but are taken down due to DMCA notices.
  • “Exclusive” listings on eBay or random websites are often reselling stolen or low-quality scans.

Legal and Ethical Considerations

  • Copyright and Intellectual Property: Always respect the intellectual property rights of manufacturers. Schematics are often copyrighted and should not be shared or used without permission.

  • Usage Rights: Even if you find a schematic, consider whether you have the right to use it for your purposes. Some shared resources might come with specific licenses.
