Hi guys,
Been in the computer service/repair industry for the past 16 years, but have never taken an electronics course, (though I'm very interested too). I've learned pcb component repair on my own as I went.
Anyway, a slow month at the store has motivated me to go though several laptop mobos that I had piled up as "bad". I'm having varied success, but here's my quick question, (and please don't laugh.... remember, no formal training):
Modern pc motherboard resistors, (square flat sort) should always conduct voltage through, (both ends) correct? So, if a reading of 19.60 volts on one end, and nothing all on the other end, then this resistor is an issue right?
I've had limited success over the years with replacing resistors of this type, (and blown caps which are easy to find). But with all the research I've done today, I can find very little on the web relating to the voltage input/output of a resistor, (and not testing of resistance). I just want to know why when I test other resistors of the same type on the same motherboard I get 19.6 volts on both ends, but on a few, 19.6 and nothing. See my point?
Any input is greatly appreciated and thanks for reading this first post here.
