Hi everyone.

This machine when I disconnect the flex from the battery, it generates 20V and turns on.

The machine has a problem that the touch bar works but does not show an image.

suggestions? Thank you!

keyboard light works

The J5110 voltages are present, the problem is that PPBUS_G3H is not generated with the battery...

What's the problem there?
No touchbar backlight, or missing PPBUS_G3H with charger and battery connected at same time?

the problem is two.

there is no ppbus with the battery connected...

If I only connect the charger "WITHOUT THE BATTERY connected" the machine turns on.

The touch bar is another problem.

if there is ppbus with the battery connected but when disconnecting the charger, the equipment turns off.

The machine recognizes the battery and shows the percentage.

Believe it or not, that happened to me, but it's already working with the battery.

Now I focus on the touchbar, in the system preferences it is recognizing it, I even pressed it and the volume symbol was activated... the problem is that it does not light up...

The keyboard dims when you cover the camera.
