820-01814 A1990 WITH 5V 1.18-1.37AMP

[Jeffotskie26]

5V 1.18-1.37AMP on all ports, ldo are all ok
ppbus is 12.2v
all coils on ssd 0v nothing shorted
AWAKE and SLPS2R is present but pulsing.
tried AC2 having error 4042 after having this error
board suddenly turns into 20v 1.37amp but nothing overheats (thermalcam)
after this i didnt try check for the ssd coil voltages.
anyway board is clean no any watermark/corroded parts.
posible T2????

1.37A without battery connected?
Then must have voltage on many coils; check them.

 

[Jeffotskie26]

5.14-5.18v 1.18-1.37amp with battery
only bigcoils got voltage and stable: L7660 3.3v and L7030 5v
the rest 0V.

STOP checking PPBUS_G3H at L7030 on such board.
Did you see any direct connection???

Disconnect battery and test with 87W charger.
Try starting in SMC bypass mode.

 

[Jeffotskie26]

with authentic 87w charger nothing happens

 

[2informaticos]

Which voltages appear with 87W charger (whitout battery)?
PPBUS_G3H is steady?
Also check AWAKE and SLPS2R voltages.

 

[Jeffotskie26]

from my previous post all tested without battery using 87watt charger.
*** 5V 1.18-1.37AMP....

"with 87W charger (whitout battery)
-------------
5V 1.18-1.37AMP"
I doubt about such high current without battery...
