Common fault: If ACDET is below 2.4V, the board will not turn on. Check voltage divider resistors (R5001/R5002) listed in the schematic.
: Includes details for RTL8111HSH-CG LAN, USB 3.0/2.0 ports, and NGFF WLAN+BT modules. La-e791p Rev 2.0 Schematic Diagram
The is not merely a wiring diagram—it is a diagnostic instrument and a historical record of hardware refinement. From its revised power sequencing to added test points and improved RTC backup, each change solves a real-world failure mode. Common fault: If ACDET is below 2
