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?
