Power Supply
The power supply converts the ac voltage to dc voltage and provides power for the following:
ŸSystem board set
ŸDiskette drive
ŸHard disk drive
ŸAuxiliary devices
ŸKeyboard
ŸLCD panel
ŸPCMCIA cards
Voltages
The power supply generates five different dc voltages: VCCCPU, VCC3A, VCC5M, VCCSW, and VCC12M. Figure
maximum current for each voltage.
Output | Voltage (V dc) | Current (A) |
