Hi, all
LA-L191P BQ24781 signals pin 28 -> 19V [VCC], pin 5 -> 3.3V [ACOK] pin 6 [ACDET] 2.6V, pin 24 -> 5.3V [REGN], pin 25 -> 5.3V [BTST] ,
missing +3VLP -> EC -> signals for manage BQ24781. In the power sequence the +3VLP is the first signal in AC mode.
I presume that the bios is working because one time the motherboard generate +3VLP and goes ON but after a shutdown the situation
came back to no power on -> no main 19V. The question is: who generates +3VLP which is the basis of all other signals?

Every time with the BQ24780S it's like...

I can't find one for the life of me! Does anyone out there feel kind enough to share one with me? I thought it was the VRM for the GPU that had failed (showing 0.1-0.2ohms) however i fear its the GPU, which i'd like to find out without removing all caps and other components on the power rails!

Kindest regards,
Lee/Husky
