Lenovo E15 Gen 1
Hello,
I have a weird problem with a Lenovo E15 Gen 1, intel i7 processor.
The battery is charging fine with 2,2 Amp but the board is not coming on.
Main power rail with battery plugged in is 12,5V and without battery 9,2V.
3,3V LDO, 3V and 5V power rails are present, current draw without the battery is 0.039 Amp and when i press the power button iti goes to 0,041 Amp and then drops back to 0.039 Amp and the power button led comes on and stays on.
I`ve tried to change the bios with one found on this forum but no changes.

Yes, each of this pins (19 and 20) is connected to ground through a resistor and connected together by a capacitor.
Someone worked on this bord and probably meesed this up.
