Hi, I need help to identify 2 component on motherboard GL752VW rev2.1 fault of shema detailed motherboard that has suffered a water damage (+ 3VS in short circuit) pch / audio codec already replaced the motherboard startup image in External (not internal) and has trouble starting to the button (functional keyboard (reset ok!) Forced to put the finger on RN3002 to start the first time after plugging the power then more problem for on / off with the keyboard Screen boarwiew of the components identified Thank you for your help (Sorry for my mediocre English)
I do not have a motherboard available, I can not determine the index of this resistor. A similar motherboard is needed for comparison.
Ok an idea about the reference of U4503? I specify that the picture is not the original one because burned so no information readable on the original thank you
