Stuff like this is often corrected by a BIOS
update for the laptop.

Alternatively, search support.intel.com for
Speed Step info and problem resolution.

SP2 probably overwrote a system .DLL, driver
or something else that Speed Step uses.

You're welcome, Maurice.

Thank you Green and Maurice.

Sadly I was unable to solve this problem so far.
I indeed found a newer bios update, but it did not change anything

I found no article on support.intel.com that seemed to fit my problem,
but I tried to make sure all drivers are up-to-date. I also used the
intel inf installer and then went throught each component in the device
manager and clicked "update drivers".

I tried the Intel Processor Frequency ID Utility, which said my
processor was not supported by it and I should instead use the Intel
Processor Identification Utility

Using this, I indeed got different reported speeds before and after
standby.
My Processor is recognized as:
- Intel Pentium M Processor 1400MHz
- with reported Speed 0,95Ghz, 397Mhz Bus, before standby
- with reported Speed 1.40Ghz, 400Mhz Bus, after standby

Is there anything left I could do to pin this problem down?
It really makes working with my notebook difficult.

[V Green]

Don't know really where to go from here
except the following:

if it's still under warranty, send it in

if it came with CD's to restore it to "out of the
box" condition, do it and don't apply SP2. If
you're a careful user, you don't need it.
