Yes, 20V present
Yes, I use certified 100W cable and 100W power adapter.
Now consumption is 1.4 I think due to the battery charging. The consumption climbes to it values.
Ok. I will try....Leave a comment:

J6951 connector with both battery and power adapter attached:
pin 2: SMBUS_SMC_5_G3H_SCL = 3.408V
pin 3: SMBUS_SMC_5_G3H_SDA = 3.408V
pin 7: SYS_DETECT_L = 0.016V
Now the motherboard does not start
Current consumption of the board with all parts attached is 1.707A.
PPBUS_G3H = 11.25V with attached power adapter
PPBUS_G3H = 10.52 without power adapter (only battery attached)...Leave a comment:

Now it is still in the working mode. It boots without any problem. Measurements will probably need to be taken, when it switches to the mode from which it no longer starts without the battery disconnected?...Leave a comment:

Hi, I have the close problem. Motherboard do not want to start with the battery connected if I keep the laptop closed and disconnected from external power for a day or so. After reconnecting the battery, it can to start some amount of time. I tried to disconnect keyboard, trackpad, reset SMC, replaced the battery to the brand new one - gave no result. Motherbord lookes great like just from factory. No any tracks of liquid damage, all is clean. But there is some strange thing. The PPBUS_G3H is only 10,68V. On the gate of Q7065 is 2,46V. What to do next? Which direction to move in?...Leave a comment:

ASUS ROG STRIX G513-6050A3249301-MB-A03(A3)
Hey guys, I picked up the mask on the PAD6160 and now there is a short circuit on the board. Moreover, either from the VRP5V_19V5IN side, or from the PVBAT side. What to do? -
Macbook Air 2020 13” model: A2337 backlight is on but no image
Hi all! MacBook Air A2337. There are no traces of liquid or obvious damage, the motherboard is visually in perfect condition. The image is displayed on the external screen, but only the backlight works on the internal screen. There is no image, and the camera on the built-in screen does not work. How to exclude during diagnostics that it is the screen that is broken and not the motherboard? What signals should be present on the connector with the screen removed and connected? -

Re: acer motherboard EH5VF LA-H501P
I have a case with a missing screen backlight in revision R1A. There are no CX9 and RX10 items in this revision. Does this mean that the problem is definitely in the PCH?Leave a comment:
