    100 ohms resistor helped. Is it good for SMC ?

    Is there a future risk if 3.3v is applied directly to PM_BATLOW_L ?

    I put in 1k and it's 1.8v. Unfortunately it still does not start. How best to do a reballing ?

    With both battery and charger connected is steady voltage 1.05v. Without batteries momentarily 3.3v on PM_BATLOW_L after a while 1.05v. With battery alone is 1.05v when I press the power button. Starts when I connect pin 1 to pin 2 - R1212 I replaced R1212 and it started up for a while

    Sorry, I meant the bypass all along. When I release the power button, windmills don't move . Momentarily 3.3v on PM_BATLOW_L.

    Now charging the battery. In my case, the fans did not spin. Maybe I'm doing a SMC reset wrong. I did this without a battery connected.

    I tried . Does not charge the battery. SMC bypass without batteries - Holding down the power button the board Just stays at 5v until I let go to 20v

    No liquid damage, board in perfect condition. According to customer, this MacBook suddenly died on him. PPBUS_G3H 12.59v PP3V3_SUS = 3.3v PM_BATLOW_L - 1.05v PM_SLP_SUS_L - 3.31v PM_DSW_PWRGD - 3.4v PM_RSMRST_L 3.3v PM_PWRBTN_L - 3,3v UB300 CB300: 3V3_G3H: Diode-Mode: 0.331 3V3_G3H: 3.415V...

    I tested on 3 different batteries. I noticed that PPBUS_G3H without battery has 12.56v and with about 11v. - on three different batteries

    Yes or turns on with trackpad, but battery disconneted.

    SMC bypass does not help. The battery is tested and operational. MacBook with battery loops startup sound. Only disconnecting the battery or the trackpad flex helps.

    Diode mode shows no differences. Test ASD stuck on CPU test. Hear a jammed chime during startup with trackpad flex.
