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
