HP EliteBook 840 G4 won't power on
Hello, i have problem with HP EliteBook 840 g4, laptop was working normally but only on 1 ram slot - second was damaged so i decided to unsolder secon slot, i did it properly - no solder joints shorted - but now laptop won't start, zero reaction for clicking power on button and weird behaviour - laptop shows orange light means charging - even if there is no battery inside.
What should i check first?

Re: Acer E5-573g weird behaviour
Another thing: i desoldered PQ55: IMD2AT108 and after this laptop turning on and showing charging even if i first plug charger in to wall socket and then into laptop but issues with charging still are there - 8.4v on charging coil, when i turn on laptop - 2.4v on this coil.
Under thermal camera nothing getting really hot, when i checked it with "clicking sound" - just 1st mosfet and PQ55 were pulsating but still not really hot - around 25 celsius.

Re: Acer E5-573g weird behaviour
On the 1st mosfet there is 9.4v on gate, on the second mosfet(another side of board) there is 19v on gate. - measured in situation when i plug the dcin jack first and then to the wall (laptop showing orange light but not charging - 8.4v on charging coil - after 10hours battery charged around 0.05v - if it can be named as charged).

Re: Acer E5-573g weird behaviour
Battery charging mosfets and dcin mosfets checked - ok
another behaviour noticed: when i plug the dc jack into laptop, then to the wall socket diode showing charging - orange and in this situation voltage on battery charging coil is around 8.4v but when i turn on laptop, this voltage dropped to 2.4 v and staying this level

Elitebook 840 g2 turning on no display
I have 6050a2637901-mb-a02 with all present voltages except cpu voltage.
Fan on full speed after startup, no display ofc. This is orginal bios, any ideas?
already tried lot of bios from this forum, even clear bios from hp - same result.
Cpu converter replaced, same result.
Resistance on CPU coil around 60-75 ohms i5-5200u.
Other resistances on coils looks ok.
ec reprogrammed and replaced ec winbond - same result....
