Default Lenovo B490 (20205) LB49A Keyboard Problem

1. Laptop Bios Password Locked
2. Some one Programmed Bios to unlock ===> unlocked
3. He Programmed with different version. Original: H9ET82IT but programmed is H9ET83WW.
4. Problem Started here KB is working well within Bios but not working even in DOS (some keys working with different behaviors also none of Alpha Numeric keys working)
5. Then reprogrammed again H9ET82IT the same Problem
6. Tried different versions such as H9ET90TO the Same Problem

the problem not only in internal keyboard also in external keyboard(USB)

Board: Lenovo B490 LB49A MB 12208-1 48.4WZ01.011

Can anyone provide Solution and Bios( Some China Sites such as Chinafix, vinafix have these bios but i have no credits to download from them)

Note: the mentioned bios H9ET82IT & 90TO works in the same model other laptops

Sorry for the lengthy description
