Power Supply
The power supply converts the ac voltage to dc voltage and provides
power for the following:
System board set
Diskette drive
Hard disk drive
Auxiliary devices
Keyboard
LCD panel
PCMCIA cards
Voltages
The power supply generates five different dc voltages: VCCCPU,
VCC3A, VCC5M, VCCSW, and VCC12M. Figure 1-8 shows the
maximum current for each voltage.
Figure 1-8. Power Supply Maximum Current
Output Voltage (V dc) Current (A)
VCCCPU + 2.9 or + 2.5 2.20
VCC3A + 3.3 2.00
VCC5M + 5.0 3.00
VCCSW + 5.0 0.01
VCC12M + 12.0 0.11
