I posted this on Overclockers UK a couple of weeks ago and was pointed in this direction, I also have a few other topics I'd like to discuss now that I've found such a forum but I'll be keeping my workload to one or two "projects" at a time, my latest retro kick has landed me with a couple of boxes of stuff to play with, enough to get me from the late 80's to the early 00's!
I'm no stranger to soldering and electronics, although it's all hobby related, my job isn't even remotely related!
I have an M572 motherboard that's missing some capacitors, I'm going to replace all the capacitors but obviously don't know the value of the missing ones, I could guess, going by the silk screen and photos from google, but I'd rather have confirmation!
Looking at the board with the CPU socket at the bottom and keyboard connector at the top, the capacitors in question are located towards the bottom left of the board, the first, EC19, at the top left corner of the CPU socket, next is EC23, to the right of the BIOS chip, then EC29, EC30, EC31 and EC32, all together right at the bottom of the board, bottom left corner of the CPU socket.
My guess is EC19 is 470uF 10v, the other 5 are 1500uF 6.3v
Any help will be much appreciated!
