5.  Add all additional wake-enabled devices’ and nonwake-enabled devices’ standby current

requirements as applicable.

6.  Add all the required current totals from steps 1 through 5 to determine the total estimated

standby current power supply requirement.

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
•  Mouse @ 70 mA
USB requirements are calculated by totaling the following:
•  One wake-enabled device @ 500 mA
•  USB hub @ 100 mA
•  Three USB non-wake-enabled devices @ 2.5 mA each

The operation of Resume on Ring can be summarized as follows:
•  Resumes operation from either the APM sleep mode or the ACPI S1 state
•  Requires only one call to access the computer
•  Detects incoming call similarly for external and internal modems
•  Requires modem interrupt be unmasked for correct operation
