Hello Guys, I have a macbook pro i7 that has some light water damage on it. When i connect the charger to the computer without the battery it shows me a orange light as if its charging. It doesnt boot. Im assuming there is a problem with the current sensing. During visual inspection I was able to find some unhealthy components near the ISL95870. I did a beep test on both sides of this capacitor and it beeped to ground. The resistanc eof the resistor that apears besides that cap is 10.7Ohms. I have also reballed this ic since some pads were corroded. I would love to measure my main power rails and troubleshoot it a bit more but i dont have the brd and schematic for this board. Can anyone share or enlighten me? Thanks

Airs and retinas always have orange light with battery disconnected. What is wrong with it, is it not charging, not seeing a battery, or is it working fine? This is normal behavior.
