820-02020 a2338 coffee damage
after i clean the affected areas i manage to turn on this macbook i just having problems on battery that cant charge
even i change new battery. i just notice i didnt get voltage on PPVBAT_AON with diode to ground 1.542
but i have voltage on PPVBAT_AON_CHGR_R and CHGR_BGATE (Q5265) which is 13v
i decided to change u5200 (intersil 9240HI) but i notice i used the intersil chip with 9239HI
now the macbook cant turn on having 5.19V with 1.42a usb meter after this i decided to put back the original u5200 but i still getting 5.19V
now i dont get voltage on PPBUS_AON with diode to ground 0.485
i dont know what to do next. please advice me. thanks in advance.
