XO4 C1 C2 Changes
C1 Electrical Fixes
These changes fix problems in the C1 prototypes:
Steps need to be taken to protect Q8 (HDMI hot plug detect circuit) from ESD.
C1 Layout Fixes
The ground pads for the internal SD slot need thermal isolation from the ground plane.
CForth Serial Port
The ground pads for CN23 need thermal isolation from the ground plane.
C1 Mechanical Changes
This was not fixed in the C1 laptop. It will be fixed in C2, even if it means delaying production (it was.)
