Yeah, try that.
Possibly bad U8100...
When I replaced the U8440 from another board the laptop stopped showing a picture on an external monitor. Once I soldered back the original U8440, it started showing a picture again, but now the keyboard and trackpad are not working.
I replaced another trackpad and flex for it but still the same. There was corrosion damage on the trackpad connector initially on the board but I took care of that and it was working the trackpad and keyboard. The other trackpad is not known good, so cannot confirm at the moment with another one. Can the trackpad stop the keyboard from working if it's not good?

Of course, KB information (I2C_KBD bus) goes to TP electronics.
KB and TP info go to M1 CPU through SPI_TPAD bus.
