    again a1466 again there was some liquid contact in an a1466 j6100 area. Battery is charging SMC_RESET_L :3.4 Volt SMC_BC_ACOK :3.4 Volt PP3V42_G3H : 3.4 Volt PM_PWRBTN_L :3.4 SMC_SENSOR_PWR_EN : voltage comes and goes 3.4 PP5V_S4RS3 : voltage comes and goes

    I plugged in the u7941 from another working device, still the same

    820-3209 No power

    I changed U7941 before. Doesn't the result need to be a voltage on pin6 for output from the same pin3? Or is only pin2 SMC_PM_G2_EN voltage sufficient? What if I jump to try between pin2 and pin 3?

    820-00850 5 volt 0,226A

    The device must have a 20 volt input to enter dfu mode, right? I see 5 volts on the screen, also the t2 chip is a little warm, is this normal? Does dfu mode work at 5 volts?

    It stays at 5 volts 0.223a. I noticed that the T2 chip got a little hot. There was liquid contact, but I could not see any corrosion. They cleaned it before and sprayed wd40. PPBUS_G3H: 12.30Voltage PP5V_G3S : No Voltage

    820-3332A a1398

    the device is pulling 0 to 0.89 amps. 0.90 amps continuously repeat after 0 amps SMC_PM_G2_EN 0 volts then 3.4 then zero constant again cpu is a little hot PPVCORE_S0_CPU_PH2 (l7520 ) 0 volts then 1 then zero constant again Could it be cpu failure?
