G6-1169ea (R18D) low +VCORE
Hi everyone,
I have G6-1169ea (R18D) with low +VCORE, just 0,4V instead of 0.77V. Can anyone explain how to troubleshoot this?...Last edited by Artuha; 08-11-2020, 02:53 AM.

Re: Motherboard LA-9105P, no CPU power, 7 beeps
QZ11 have two resistors RZ18 (one side 19.8V other 15.4V) and RZ21 (one side 15.4V and other ground) UZ1 are open and make +1.5V from +1.5VS
I do not have idea how 5V can be on resistors, but I'm newbie in electronics and may be wrong. See 1.jpg and correct me if I'm wrong.
About PU400 - on PL400 I have 1.8V - in my opinion PU400 works as expected.
QZ1 also works Gate 19V source and drain 5V...

Motherboard LA-9105P, no CPU power, 7 beeps
Hi everyone,
Have LA-9105P motherboard with no power on +VCC_CORE, resistance 4 Ohms.
Both BIOS firmwares (4MB and 2MB) was re-writed.
PCH_PWROK are OK 3.3V
VR_ON OK 3.3V
After board turn on SLP_S5#, SLP_S4# and SLP_S3# the signal level rises to HIGH and immediatly fall to LOW.
Cooler keeps running and voltages stay on it's work values.
Post card connected to 30 and 31 pins of kb9012qf no POST codes.
CPU PWM controller ISL95833 was replaced without results.
PCH and CPU are cold. May...Last edited by Artuha; 03-27-2018, 03:58 AM.
