NOTE
AGP and PCI requirements are calculated by totaling the following:
•
One wake-enabled device @ 375 mA
•
Five non wake-enabled devices @ 20 mA each
PS/2 Ports requirements per the IBM PS/2 Port Specification (Sept 1991):
•
Keyboard @ 275 mA (Actual measurements are 220 mA-300 mA, depending on the type of
keyboard and the operational state of the keyboard's LEDs.)
•
Mouse @ 70 mA
USB requirements are calculated by totaling the following:
•
One wake-enabled device @ 500 mA
•
Three USB non-wake-enabled devices @ 2.5 mA each
The USB ports are limited to a combined total of 700 mA.
CNR requirements are calculated as follows:
•
One wake-enabled device @ 375 mA
•
Non wake-enabled devices @ 20 mA
