Chicago_cp_hpc

hi

I received a laptop with keyboard issue.
but whatever one you insert, there are series of keys that do not work.
I already flash the bios but it's always the same thing.
After testing with the multimeter, I found that the output of +V3.3A had not correct impedance (34 ohms).
I suspect EC. but to be sure , i need diagram (CHICAGO_CP_HPC 630 hp).
