Hola! Tengo éste portátil con placa base KBYF0 LA-5051P REV1, el cual al hacerlo funcionar con 2 memorias no manda señal. Si coloco una sola memoria, el portátil enciende pero si conecto la pantalla externa da un error gráfico y se bloquea.
Con las 2 memorias insertadas, y sin recibir señal en LCD ni en pantalla externa, he realizado las siguientes mediciones:
Las fuentes básicas funcionan correctamente. +1,8V, +0.9V, +NB_CORE = 1.1V, +1.2V_HT = 1.2V, CPU_Core = 1V, SB_PWRGD = 3.3V
En JLVDS:
pin 1 = 3.3V, pin 32 y 36 = 3.3V, pin 38 y 40 = 18.65V, pin 29,31,35,37 y 39 = 0V.
En Q1: pin 1= 0V, pin 2-3 = 3.29V
En Q2: pin 2-3 = 3,25V pin 1-4-5-6 = 0V
¿Estas mediciones son suficientes para determinar que U25 (RS780M) es el causante? Gracias.

Hello! I have this one portable with motherboard KBYF0 LA-5051P REV1, who to make it work with 2 memories sends sign. If I place an alone memory, the portable one it ignites but if I connect the external screen it gives a graphical mistake and is blocked. With 2 inserted memories, and without receiving sign either in LCD or in external screen, I have realized the following measurements:
The basic sources work correctly. +1,8V, +0.9V, +NB_CORE = 1.1V, +1.2V_HT = 1.2V, CPU_Core = 1V, SB_PWRGD = 3.3V
In JLVDS: pin 1 = 3.3V, pin 32 and 36 = 3.3V, pin 38 and 40 = 18.65V, pin 29,31,35,37 and 39 = 0V.
In Q1: pin 1 = 0V, pin 2-3 = 3.29V
In Q2: pin 2-3 = 3,25V pin 1-4-5-6 = 0V
are these measurements sufficient to determine that U25 (RS780M) is the causer? Thank you.
