Motherboard resistors RV2 and RV3

\015 Can anyone help with the values of the 2 surface mounted resistors RV2 and RV3, by the charging socket on the motherboard, please? \015\012\015\012Unfortunately, someone attempted to replace the DC socket and dislodged these 2 resistors in the process.\015

Answers :

RV1, RV2, and RV3 are capacitors. They're actually dark green in color because they're made primarily for automotive applications. If you remove one and measure it with a capacitance meter you can find the value. On a 600M/D600 I believe they're 150pF, but on other boards they may be 100pF. Digikey part numbers for them are 490-4962-1-ND for the 100pF, or 490-4767-1-ND for the 150pF. Good luck!
I came across you post while trying to solve this. the rv2 might have fallen off due to design flaw. the value of rv2 is .4 ohms, just solder the two pins together and it will work perfect (better then dell's design). as for the rv3 it's value is 280k ohm this will need to be replaced.
