C'est quoi NAP ?, dans le Hardware.prefpane

C'est quoi l'option "Power : [] Nap (à cocher)" ? dans cet Hardware prefs...

[Guest_Perplexe_*]

After installing CHUD, go to System Preferences, open the "Hardware" pane and turn off "Nap".

Apparently this option turns off the G5's ability to use processor idling, eliminating the beeping noise.
Hope this helps those with the problem. I don't have any such problem with my dual processor 2.0GB G5.

Mais il semble que l'option revienne à chaque reboot.

according to:

<http://e-www.motorola.com/files/32bit/doc/data_sheet/MPC7455RXPXPNS.pdf>

nap mode results in 3.7 watt usage vs (35.5-50.0) watt usage at full throttle, but that doesn't answer my question as to what 'nap' is.

I get the feeling that 'nap' is like 'sleep' but how does it differ from 'doze'?

>Idle: The system is idle with the main processor stopped in Nap mode. All clocks are running so the system can return to normal within a few nanoseconds. (Cache coherency is maintained.)

vs

>Sleep: The system is completely shut down with only the main meory state preserved for quick recovery. All processors are powered off with their state preserved in RAM. All clocks in the system are suspended except for the crystal used by the PMU99 IC (Power Management Unit).

trying to read further on the 7455 at Motorola leads to information overload...

Il semble que cela puisse être intéressant pour la consommation des portables mais Apple recommande de le laisser coché, alors ...
