Post your bios backup, and give laptop model number such as 15-bd003tx.

Still wrong, I think so problem hardware. After push power buton UC1 not read UC2 (25B64), 3,3V ok, no clk pin7, oscillations YC2 UC1 ok. Or wrong EC 128kb in KB9022 inside memory, is possible ?
I hope that I will be understood.

It could be the KB9022.Most of the ITE,Nuvoton,ENE chips for sale are used .
