    Dell Latitude E5570 (Motherboard LA-C642P)

    Does anyone in the world have the schematics for this motherboard LA-C642P Rev: 1... Actually the Mosfet AO7401 & a ceramic capacitor at the input near the DC-in jack are burnt out. The 19v positive from the DC-in jack goes directly to the source of this FET AO7401 & the drain is directly connected to one of the ends of the ceramic capacitor & the caps' other end is soldered to ground. I did get the # off this P-Channel MOSFET which is AO7401 but do not know the true value of this ceramic capacitor. Can anyone fiigure out the vaule of this ceramic capacitor??? The notebook works on 19.5V-3.34A-65W. Any help will be much appreciated, thank you.

    Probably not a critical capacitor. Will be 25V rated for sure, if it's a small one it may be like 0.1uF, large one maybe 1uF or 10uF. You can measure it with calipers to know the package size.
