Hello colleagues, good morning, it is a pleasure to greet you.
Could you help me? First of all I want to tell you that this forum has been very helpful to me, here I find diagrams and clarify the doubts I have since I am new to this, but I find the subject of plate repair. interesting
I have a dell board, model
Cedar_Intel_MB 13269-1
PWM FX3MC REV: AOO
It is off, with a consumption of 0.034
reviewing the diagrams that I leave attached so that you can help me
I have all the signs
+ RTC_VCC
RTC_RST #
DCBATOUT
3D3V_AUX_S5
3D3V_AUX_KBC
S5_ENABLE
up to S5_ENABLE of KBC pin 14 which is in high voltage without pressing the button,
I replaced the PU4503 giving the same result, ping 6 and pin 20 on voltage 0, it receives voltage through pin 12 with 19.0 V, pin 3 VREG3 3.30 V, I do not get VREG5, nor do I have voltage on pin 18 which I understand gives output to 5V_PWR to become the next 5V_S5 signal
I would like to know where I can find the error or if I need any conditions to enable them.
PWR_5V_LL1 -> 5V_PWR -> 5V_S5
PWR_3D3V_LL2 -> 3D3V_PWR -> 3D3V_S5
which are the following signs.
