HP Vectra VEi8 HP Vectra VEi8, Technical Reference Manual (Product Description - Page 12

NOTE 1 System Overview Specifications 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. 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).
