Re: dell E6410 no power
Which voltage rails on PU19 are missing ?
There are the 2 x LDO low current rails supplied by this Maxim device.
There are 2 x high current switching rails supplied by the same device.
What is the voltage on pin # 4 (ONLDO) of this regulator ?
Also, measure the voltages on the following pins of PU19:
pin # 5 (RTC) - should be 3v3
pin # 7 (LDO) - should be 5v0
pin # 14 (EN_3V_5V) - signal enables / disables the switching regulator (5v)
pin # 27 (EN_3V_5V) - signal enables / disables the switching regulator (3v3)
