If you want, I can:

Before downloading, always verify your . The "11269-2" is the specific identifier you need. Using a schematic for an 11269-1 or 11269-3 may lead to incorrect component values or pinouts, potentially causing further damage during a probe.

A shorted ceramic decoupling capacitor on the System main rail (B+ / +19V) . For those performing a physical replacement or deep

Over the past three years, the primary source for this schematic was a single Russian forum upload from 2014. That original file had two critical errors:

Before the system triggers a full boot loop, it requires stable standby voltages. The schematic dictates the PWM controller pinout responsible for creating the +3VALW and +5VALW lines. Short circuits on these rails typically stem from failing ceramic filter capacitors or a blown controller IC. 3. Embedded Controller (EC / Super I/O) | | Reference Design R‑LM495‑A | Complete PCB

The PU1 (BQ24737) charging IC fails or the ACDET resistor divider fails.

Locate the SPI Flash BIOS chip (usually an 8-pin IC like a Winbond 25Q64). Check Pin 8 for 3.3V.
