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

CD-ROM drive

Auxiliary devices

Keyboard

LCD panel

PCMCIA cards

DVD drive

Voltages

The power supply generates six different dc voltages: VCC5M,
VCC3M, VCC12, and VCCSW. Figure 1-8 shows the maximum
current for each voltage.
