MacBook wont power on

I bought a macbook a2159 with a no power issue, when i plugged in a charge meter it jumped to 5V .3A then immediately to 0.00A and then kept looping between 0.00A and 0.02A. Then i noticed that the .3A draw happens only when its unplugged for a while and one thunderbolt port loops faster than the other. Theres only 2 coils that are getting power (2R7 is getting 6 volts and 1R0 is getting 5 volts). When i inspected the board i noticed that there is a discolored q9621 chip

. (I dont have a thermal camera or an external power supply) and i dont know where to go from here.]
