Pin 27/28 22.00 pwrbtn drops to 0000 and back to 3.4v batlow is 3.4v but what makes me crazy now it starts it self without flex I/O ?!

No sir , nothing

Yes by smc bypass.

AVREF_SMC = 3.3v

Sir, SMC_PBUS_VSENSE = 000.0V SMC_DCIN_VSENSE = 3.092v SMC_BMON_ISENSE = 059.0mv SMC_DCIN_ISENSE = 038.0mv SMC_BMON_DISCRETE_ISENSE = 164.3mv

ok Sir, - does it turn on on charger only? --- Yes only by SMC bypass !! - does it turn on battery only? ---- Yes , just by pressing power button or shorting smc_onoff ! - does it turn on with both charger and battery connected? Yes , but the board is getting Hot on both magsafe2 and powerDC !

No i dont have another one , but why it turns on only on battery without charger but dont charge ?

I tries 3 lio boards and flex cable still the same board looks clean. The problem is only when i plug the battery in and starts charging to much amps .

PPbus_g3h = 8.59v PM_BATLOW_L = 3.42v it turns now ON ! when i unplug the LIO Connector it turns on but when i plug the battery its charge to much amps . but it stays on with battery when unplug charger ?

I changed R7151 with high omhs , now normal value 2.45 ohms . but it's not turning On . both ppbus , pp3v42 available ! what to check now ?

Mac works normaly on battery but when i plug megsafe charger the board is going hot and charges to much amps . also pin 17/18 on u7000 resistance is 150 omhs ?? fixed backlight bad chip .

Hi, i have a mac air with green light , it's taking to much current when battery and charger are plugged in ?

Trash it or replace pp3v42 components ? Have a lot of donor boards .

I'm getting 18.06v on pp3v42 ?

I removed the SMC , U2600 , U5750 , U4650 , all of them got hot , now on diode mode on L6995 pin2 = 0.433 , pin1 = 0.333 ? now what to do ? reball smc ? ?

The SMC is going hot !!

I have this broken srew hole broken ? Can this make the short ?

On L6695 pin2 = 0.000 pin1 = 0.325 those values are with lifted coil . should i put U7000 and then check for short i can i do it without ?

L6695 = right pin 0.333 , left pin 0.000 L7030 = both sides 0.450 Q7030 is shorted i think. i removed it . where to check now ? or to inject voltage to find the short ?

I?m getting a shortt on Q7035 replaced it 3 times still gets really hot ? Where to check !
