I repairing these systems. If the SMC was bad you would not even get a green light on the magsafe. You'll need a schematic diagram and a the boardview (.brd) file (to find the part location. You may need to clean the board and possibly have a shorted backlight fuse (Backlight issue). If the battery doesn't charge (green light) the issue is possibly the Intersil ISL6259A (CSI/CSO) or the diode connecting the adapter to the Intersil.
