how long have I been on a laptop? never new there was a mode that said "max battery life" (or is this new in power management?)...I wonder how much extra time this will give me. processor clocks down to about 800 mhz, lap goes into standby in about a minute if idle. I also notice desktop mode, and always on...always on, the processor clocks up to a little more then spec. in general, the performance differance seems quite large.
