Ok, I’m after a little help here….. I have recently installed Vista beta 2 on my Toshiba A60 Laptop, It has a Mobile Intel® Pentium® 4 3.0GHz processor, but windows reports it as running at 1.52GHz (when connected to AC power), so far I have played around with the power profiles and made sure it is set to 100% processing power but no luck, have also had a good look at my old friend Google, but to no avail. I have also tried installing the Toshiba power manager for my model but that failed miserably.
If anyone has any ideas they would be greatly appreciated.

P.s. I have no problems at all in XP it works at full speed.

Many thanks in advance, Logan

Ignore what Vista says, check your BIOS prompt for the true speed.

Most laptop CPUs turn down their speed unless it is needed (ie 70-100% CPU usage), this helps to save battery life. 3.0GHz is more than enough for Vista, and if Vista needs a speed boost, the drivers will automatically ramp up the CPU when it is needed.

ie. My Athon 64 3000+ only reports 800MHz when it is idling. (true speed is 1.8GHz)

Thanks,

I'm guessing it is actually running at 3.0Ghz, don’t seem to be having any speed problems. On second thought I suspect its just a reporting error due to hyper threading.

If you find vista is running fine, then it could be an issue with the performance center reporting. Submit a bug report.
Also blog your vista experience

Hi Logan

If the processor wasn’t heavily loaded it could well drop down to a lower clock (as it should in that case) – if however it appeared to be pegged at close to 100% utilization and still shows as 1.5GHz then that would be interesting - you may have found a bug

Despite running on AC processor power management will still kick in if the processor is idle or minimally loaded – often people expect that only on battery but it can actually apply at any point. Looking at the current clock and drawing conclusions based on that instantaneous value is usually deceptive – it’s like you driving to work and looking down at your speedometer once and concluding that’s how fast you went on the entire trip – you could have been stopped at the lights, or flat out on an open highway at that point...

Check that in the BIOS to make sure the processor power management setting is set to “Os Controlled” or “Automatic”.

If you contact me I can send you a couple of power management test utilities to run on the machine, and send me back the output so we can work out if you have found a bug or not

Cheers
