1 System Overview
Specifications
12
The power supply delivers 720mA at the V standby level. This extra
current is required by the 100TX hardware layer so it can perform a
remote power-on when a magic frame is received. An older power
supply should not be used for a repair.
NOTE
When the PC is turned off with the power button on the front panel, the
power consumption falls below 5 Watts, but is not zero. The special
on/off method used by this PC extends the lifetime of the power supply.
To reach zero power consumption in “off” mode, either unplug the PC
from the power outlet or use a power block with a switch. If the PC is
turned off, the time settings are maintained by the battery indefinitely
(until the battery runs out of power).
Environmental Specifications
Operating temperature and humidity ranges may vary depending upon
the mass storage devices installed. High humidity levels can cause
improper operation of disk drives. Low humidity levels can aggravate
static electricity problems and cause excessive wear of the disk
surface.
