wbmw,

PowerNow mode will be somewhere in the middle of 502 seconds and 174 seconds, but it will not be 174 seconds.

No, that's not correct, in all adaptive modes, the result is in range of 174 to 179:

The adaptive modes on the graph are:
- Office desktop AC + DC
- Portable laptop AC + DC
- Max Batter AC only
- Presentation DC only

Likewise, the Pentium M SpeedStep mode will be between 154 seconds and 420 seconds. THG obviously aimed at testing those two extremes

Actually, looking at this again, while you are wrong it the above statement, I think you may be right overall, because Centrino behaves exactly like Mobile Athlon with PowerNow. In modes that correspont to PowerNow adaptive modes, Centrino behaves like Athlon, meaning it runs top speed when necessary, and it runs in slow speed when forced to that mode, just like Athlon. This would mean that Centrino does have adaptive mode (unless power these modes are hard coded to full speed, which wouldn't make sense).

See the battery modes of Centrino here:
