CPU not running at full speed.. Why ?

[Michel S.]

Hello !

On an HP Omnibook 6100 Laptop, the system properties tab shows :

Intel Pentium III
Mobile CPU 1000MHz
727 MHz 512Mb RAM

It's a fresh install of XP + the chipset drivers only.

BIOS is at its latest version.

Laptop is running on AC.

APM is disabled in BIOS - but changing this setting doesn't change
anything.

Why is it running at only 727 Mhz ? How can I make it run at 1Ghz ?

Thanks

This is far from a software issue.
Please contact the manufacturers of said equipment - and/or the direct
support from those whom you purchased it from.
To me it sounds like a power-saving feature or a hardware defect.

What power management scheme in control panel are you using? Set it to
desktop and see if that helps.

Yeah, CPU stepping maybe. Could be a BIOS setting to turn it off. Maybe
even a too low temperature sensor setting. Unless the CPU is actually
running too hot.

HP support or laptop forums would be the place to ask..

Don't ask me why : I didn't change anything, and it is currently
running at 996 Mhz..

Go figure !

I have seen that when running on battery as opposed to AC power with a
laptop.
Sounds like a power saving 'feature'.

Try actually running some program that gets your CPU up to 100% usage,
then look at the speed while this is running. If the CPU is idling, it
does no good to idle faster, so it will shift down in speed.

Many processors will slow down if the temperature goes up, and you may
not be able to override this.

This is fairly normal behavior for a Mobile PIII.
