Re: 20 pin 8A on HP 250 G4 mb - voltage regulator?
I had realized that yes, and maybe the decision to buy the RT8243A chips was hasty.
I am catching up with repair course now and waiting to when I understand what I am doing before I make any repairs.
I do notice however two MLCCs - Multilayer Ceramic Capacitors nearest the charging port are not showing any reading in Continuity mode.
I need to find out if they are supposed to behave differently when the motherboard is powered on.
When I test most even the tiniest MLCCs there is a O.L. beep in Continuity Mode but when I test the two there is no OL beep in Continuity mode and it is the same for quite a few others.
