: Frequently cited in board repair discussions regarding power regulation.
When looking for this file, double-check your board revision . Use the "Rev 1.0" version only for boards specifically marked "Rev 1.0". For the purposes of this guide, we will focus on the Rev 2.0 . la-e801p rev 2.0 schematic
Check the input protection stage. Measure the resistance to ground on the main B+ rail directly after the current-sensing resistor. A low resistance reading (below 10 Ohms) indicates a short circuit, usually caused by a ceramic filtering capacitor or an upper-phase buck MOSFET breaking down into a short. Power LED Blinks, but No Boot : Frequently cited in board repair discussions regarding
If standby voltages are healthy but the power button yields no response, your schematic exploration must shift focus to the Super I/O (Embedded Controller): For the purposes of this guide, we will focus on the Rev 2
