resolved. I noticed that ppbus_g3h with the battery connected went to fuse F7000, that was fine.
Analyzing the i2c lines of the battery I see that they feed on pp3v3_g3h.
This voltage comes out of ic U6990.
When I measure the input voltage which is PPVIN_G3H_P3V3G3H I see that there is no...
C7020 0.70M ohms on both sides
C7023 starts to drop from 02.23M ohms to 00.69M ohms then rises to 200K ohms.
SMC_DCIN_ISENSE 07.10M ohms
SMC_BMON_ISENSE 08.10 M ohms
that's right, 12.28V
diode mode
SDA: 427
SCL: 427
With charger PPBUS_G3H it is 13.04V
SDA: 3.37V
SCL: 3.37V
When I connect the battery flex, the usb c meter restarts.
Hello, greetings to all.
This plate got liquid on it.
The problem is that it does not recognize the battery, it only turns on with the charger.
When connecting the battery the voltage on ppbus_g3h is 12.28V.
SDA line 0v
SCL line 0v
When only the charger is connected without the battery...
this board has all the voltages including the VCORE, but it does not show an image.
When it is connected to the source it reaches a consumption of 0.800 ma then it rises to 1.040 am little by little.
my question, what should I check in these models.
I understand that it could be the PCH...
This machine reaches a consumption of 0.683 in the fixed source. spin the fan.
PPBUS_G3H 12.57V
PPVCORE_S0_CPU 0.99V
PPVCORE_S0_MCP 0.925V
I realize that U6100
1: 3.3V
2: 0.20mv
3: 3.28V
4: gnd
5:000.0
6:000.0
7: 2.93v
8: 3.3v
exactly. the machine turns on but stays in the progress bar.
To my bad luck I don't have another board to test, but I'm pretty sure those voltages are missing. At least one.
Hello everyone.
I have this motherboard that takes time to turn on. I suspect it may be bios.
U6100 voltages
1: 3.3v
2: 3.2v
3: 3.3v
4:GND
5: 0.56mv
6: 000.1mv
7: 3.3V
8: 3.3V
My question is, are these values ok?
I haven't tried another bios yet.
resolved. Note that the machine when closing the screen did not return the image and turned off. Check lined SMC_LID 3.3V
resistors good.
Value in Diode pin 2 of the resistor 5252 value 2.293 abnormal.
Compared to another plate the value was 0.478
I had to make a jumper and the value...
Hello everyone.
I have this plate that turns on but when it turns off after a while, it no longer turns on.
I have to disconnect the battery and then it turns on.
PPBUS_G3H voltage is 12.10V with battery connected.
With the 87W cable connected, the PPBUS_G3H voltage goes up to 12.70V...
