    same thing on batt or charger. Area is clean arround CD3215. When I plug something into the port that the CD3215 was for it goes to sleep properly

    yeah really weird screen goes off and when i wake it its at the login screen but it just keeps the machine in an s0 state Unplugged everything except screen still same behavior

    yes backlight goes off when lid is closed

    SMC_LID only goes low when lid is closed even when put to sleep with trackpad, all SMC_LID stuff seems to be measuring right

    PM_SLP_S3_L stays high, I've tried both methods and both have the same results. Worth an ME region cleaning?

    SMC_LID while sleep 3.48v(open) 0.1v(closed) 5v_s0 3v3_s0 are up PPVCC_S0_CPU fluctuating bet 0.2-0.7v Just noticed when put to sleep with capslock on afte rabout 20seconds the light goes out for 1 second then comes back on

    This board has a wierd issue where it doesnt go to sleep properly hence draining battery very quickly. when put to sleep machine remains warm after a few hours, also if I leave the capslock key on and put it to sleep the LED never goes out

    Please disregard just saw Louis has a video for charging issues. replaced the CD3215C that was getting hot and now all working.

    No liquid damage, 3ports measure 4.98v .29a but one only mesures 5v 0.12a 3v3_g3h measures 2.5v on the 3 ports and 0v on the 1 port (bottom right when using macbook normally) Are schematics available for this yet? im using a 000293

    820-3332 in S0 but no All_sys_pwrgd

    Removed L6201 got steady 1.5v C6211 was causing the problems even though it was measuring and looked fine All fixed thank you

    820-3332 in S0 but no All_sys_pwrgd

    Yeah what i dont understand is why its giving up to 2.4v, all the resistors are good

    820-3332 in S0 but no All_sys_pwrgd

    It was steady 2v

    820-3332 in S0 but no All_sys_pwrgd

    All the resistors for u7710 circuit measure correct and changed all caps to be safe still same behavior Changed U7710 again to be sure still same behavior

    820-3332 in S0 but no All_sys_pwrgd

    changed U7710 pins of l7770 are now fluctating between 1-2.4v and machine tries to boot when in the 1.5v range then shutsoff when above 1.8v

    820-3332 in S0 but no All_sys_pwrgd

    Q7950 Pin1 0.746v Pin2 0.706v Pin3 0.777v All_sys_pwrgd 0.70v, 0.430 diode mode red on ground R7697 good 10k When removed R7968 all_sys_pwrgd goes 3.3v and boots
