80 
 
 
NOTE 
IBM PS/2 Port Specification (Sept 1991) states: 
•  275 mA for keyboard 
•  70 mA for the mouse (nonwake-enable device)  
PCI/AGP requirements are calculated by totaling the following: 
•  One wake-enabled device @ 375 mA, plus 
•  Five nonwake-enabled devices @ 20 mA each, plus  
USB requirements are calculated as: 
•  One wake-enabled device @ 500 mA 
•  USB hub @ 100 mA 
•  Three USB nonwake-enabled devices connected @ 2.5 mA each 
 
NOTE 
Both USB ports are capable of providing up to 500 mA during normal G0/S0 operation.  Only one 
USB port will support up to 500 mA of stand-by-current (wake-enabled device) during G1/S3 
suspended operation.  The other port may provide up to 7.5 mA (three nonwake-enabled devices.) 
during G1/S3 suspended operation.
