Default HP 450 G5 (da0x8cmb6e0) - keyboard problem

i have here ex water smashed 450 g5 with mainboard da0x8cmb6e0.
Water was mainly on and around kbc npce586ha2mx.
KBC was desoldered, all cleaned and soldered back...on leg was repaired under microscope.
Problem is, that some keys on kb wont work correctly - for example when i press "O" laptop turns on airplane mode.
...problem still with connected external keyboard. at first it seemed like keyboard problem...but i have tested another two 100% working keyboards and problem still.
When is internal keyboard disconnected and is connected only usb kb then all works fine.

I was not able to find service manual for this laptop.

Soo what you mean? is needed to change kbc npce586ha2mx ?
