[SOLVED]Which to believe schematic or second board?

[macitech]

Hi
Im working on a 820-3437 board I have a second board to compare with.
Schematic says there should be a chip in certain location but second board matches first board with no chip there?
Am I correct in believing the second board?
In the U5000 Group
Example R5445,5475
If it runs hot when I put it back together can I assume some resistors shouldn't be there?
Thanks!

If it is not there on another board it is probably an unused sensor. Schematic can be confusing sometimes.

What do you mean by running hot?

Hi Duke,
When I startup the machine everything works but the board gets hot neat the processor.
Ill remove the chips first comparing boards Clean the board and try again.
Problem is I pulled chips off the second board so I don't have a great comparison but Ill give it a shot.
Thanks as usual!

I still don't know what you mean with hot. Seems to me this board is fine unless it is shutting down or drawing excessive power and draining battery fast.

Hi Duke,
I need to test again but I believe you are right the battery didn't have any juice so it was charging.
I did notice it won't start just with power supply plugged in and no battery.
Machine charges fine and starts off battery.
