Hello,
I have a strange fault with a Lenovo ThinkPad E14 G2 (Board No. NM-D011 Rev. 1.0).

The first Problem, which I fixed already, was a dead TPS65944AD (USB Type-C) controller. After I fixed this fault, all functions working fine and the notebook run very well with the charger and battery.
On the next day, I tied to start the notebook with the battery, but nothing happened. I started with the charger and on windows, I saw, that the battery was empty. And this was nearly impossible, because the battery was charged. I disconnected the battery and found out, that the board...

Hello,
I have a Samsung Galaxy A22 5G with a strange error image.

If I have a call, I can't hear the voice of the interlocutor and he can't hear me.
If I switch on the lower speaker, I can hear the interloutor through it and now, he can hear me too.

If I listen music via Youtube, even the upper or lower speaker don't work.
If I switch louder or quieter, the sign on the screen show me a headphone.
If I plug a external speaker via Jack plug or USB-C, I can hear the sound.

Does anyone have any ideas, what the problem could be?​

Great! I found the information. Thank you very mutch!!!
