Speedstep Problem with XP Home SP2

Hi:

I own four Dell Inspiron 2500's. Three with
900mhz Celeron M's, and one with a 1GHZ
mobile Pentium III.   The Mobile Celeron has
Intel's sSpec number of SL5PY and the 1ghz
mobile PIII has a sSpec number of SL53S.

I purchased a SL53S Intel Mobile PIII 1ghz
and upgraded one of my Celeron based
units. The upgrade went fine, but the CPU
clock/frequency of the new PIII is only
running at 697mhz instead of 1ghz. The
chip is identified by software as being a 1GHZ
CPU, but it is only running at 697mhz. I checked
the power settings to make sure it is set
to max performance.

I am running XP Home SP2 fully patched
on all systems. The processor I upgraded
to is exactly the same mobile PII in the
Dell Inspiron 2500 and that one is running at
997mhz.

Using the Intel Processor Frequency ID Utility
the system runs the same 700mhz whether
it is running off of AC or battery. That does not
sound correct if speedstep works as I understand
it.

regards and thanks

According to Intel's website info on the original 900 mhz Celeron M
I had in the system and the new 1ghz Pentium III M  I upgraded to,
they both have bus speed of 100mhz, so it should be just plug
and play??? I don't see anything in the BIOS that refers to bus
speed.

Turns out to be a classic PICNIC, Problem In Chair Not In Computer,
situation. In rechecking the BIOS I missed a sub-heading that
did contain a setting about Speedstep.

All is well.

True, forgot that most laptops don't have much in the way of CPU settings.
What speed does BIOS show for the processor? If it's showing the correct speeds then we can narrow it down to the speedstep driver probably.
LOL I sat here finishing a phone call before I hit submit. Guess it was longer than I thought :)
