 ### Power
 
 Each Input Module supports up to 500mA on the 5V rail and 100mA on the 3.3V rail when active.
 
 When SLEEP# is low or USB is in Selective Suspend mode, modules should drop below 500uA on each rail.  This will typically occur when the
-system enters an S0ix state.  In S3/S4/S5 or when the laptop lid is closed, the power rails will typically be off.

 The Framework Laptop 16 has a protection scheme in place to prevent Input Modules from powering on unless the input deck is fully populated.
 Module detection is done using the BOARD_ID pin. It is possible to override this setting on the system, but at the risk of shorting the system
