820-2850 a1286 MacBook Pro No Keyboard/trackpad

[crazeej]

Hello Guys, i have this uncommon fail of trackpad and Keyboard where:
No Keyboard and trackpad in OS -> USB Mouse works fine!
At Startup Press Option Key -> No Reaction!

I noticed If i Close the Screen - Screen wont Turn Off!

Measured around Keyboard 3v3s3 there. Pp3v42 there and smc on Off ist 3.42....

Smc issue maybe?
Where ist z2_boost_en coming from? OK trackpad, but which Signal activate the en Signal in the trackpad? So lost on this... Maybe eine non certified Tech can give me a hint?


U5805:
Pp18v5S3 0v
Z2_boost_en 0-20mv
Smc_lid 3.42
Button disable : 0v pretty Sure measured a Lot of stuff.

Thx a Lot.
