*D8 Suspend to RAM indicator
*D8
This red indicator lamp turns on if your computer has been suspended to
RAM. In a suspend to RAM, the system turns off most of the power-
consuming components except for the 3.3V required to refresh the
memory. If D8 is turned on, it warns you that the computer is suspended
to RAM and a refresh current is passing through the memory modules.
You should not attempt to remove or install memory modules when D8 is
turned on.
