Quanta schematic covering projects Y19C and Y33 at revision 2A, a 1.33 MB PDF that also names an IT8987E, an ITE embedded controller. The name lists no laptop brand or board number, so match the Y33 code on the PCB before use. The EC controls power buttons, charging, fans and the keyboard, so its pin assignments here help when a board shows no power-on response. Use it to trace rails, verify EC supply and clock, and locate the SPI flash that holds the BIOS and EC firmware.
