820-3536-a Not charging

Got a customer come in with broken screen. Replaced the screen but now it doesn't charge, but said he was having issues with charging anyway. I replaced the magsafe and have only gotten orange light for about 30 seconds before it fades out. I took out the 820-3536-a logic board and noticed a few burned out filters. I tried re-flowing them but looks like they need to be replaced. I couldn't find a schematic for the logic board with a google search so was hoping you could point me to the right direction to get a replacement. Do these two filters have anything to do with charging?

From left to right....

R5380 pull up resistor for battery data line SDA. Value: 2K
R5381 pull up resistor for battery data line SCL. Value: 2K
R5187 pull up resistor for SMC_BC_ACOK. Value 100K
 
R5380 - 1.98
R5381 - 1.974
R5187 - 10.33

Do any of them need to be replaced? Where can I start to find out why the computer is not charging and orange light stays on for 20 seconds.

Is SMC_BC_ACOK still high after the green/orange light goes out? Looks like it had liquid damage at some point.
