Faulty HP ZBook 15 G2 Strange keyboard issue?

[paulyboy]

Hi legends,

My ZBook laptop keyboard had a few failed keys so I presumed a keyboard replacement was in order.

Order a new keyboard and exact same keys are non functional.

Examined motherboard under microscope no damage from liquids or shorts etc?

Could this be related the the KBC

ANY help appreciated

Which keys are failed? Check resistance to ground at ALL keyboard connector pins.

You actually don't need to know the good value, just need to find different resistance and check that lines up to the EC.
