Any ideas anyone about why speedstep might not be working? It's definitely enabled in the bios, and I've tried every power profile, but the CPU remains fixed at 2400 MHz (according to CPU-Z) all the time, even when CPU usage is 0%. Checked the intel website and there doesn't seem to be drivers for intel cpus, so I'm a bit stumped. Also looking at device manager there's no obvious problems.
I hope Dell haven't somehow disabled it due to the whine people keep mentioning, because that would really kill my battery life. Having said that I haven't tried the laptop on battery at all yet, but that's not really relevant since speedstep should work on AC too.
which bios?

Now showing 1600 MHz and 8x multiplier with no CPU usage, and 2400 MHz and 12x multiplier when the CPU is busy.
thats how i got my good deal, they rang me back about something(oh yea she forgot to take verification of my card number) and i said OH iv decided iv changed my mind, iv fouund another laptop etc; )
