 The display driver is not currently enabling/disabling the DCON_EN line
 controlled by the EC, to power off the dcon when the display is powered
 off.  This is very important to the lifetime of the mesh, and will improve
 the lifetime of the system even when it is running whenever the DPMS
 powers off the screen.  See:
 [http://wiki.laptop.org/go/Ec_specification#EC_Port_6c_Command_List the
 DCON power enable/disable] bit in the EC specification for details.
