Hello, Intel CPUs have a technology called SpeedStep which dynamically adjusts the processor speed depending upon whether it is operating on battery or AC line power. From what I recall, Windows XP has support for this technology embedded in it, but a driver is required for older versions of Microsoft Windows.
I am not sure why your T42 is operating at the slower speed, but you could try installing Christian Diefer's SpeedSwitchXP utility and see if it can enable the higher clock speed. It can downloaded from the author's web site at http://www.diefer.de/speedswitchxp/index.html. Regards, Aryeh Goretsky At 10:00 AM 12/26/2009, you wrote:

Setting cpu speed to 'max performance' (battery and mains power) in the Thinkpad Power manager has no effect. Setting cpu to 'max performance' (battery and mains power) in the BIOS seemed to work for a while, but now I'm seeing 599Mhz again. I need to resolve this problem to get AVG antivirus to look at a CPU usage problem I have - they say at least 1.5Ghz is required for AVG 9. Chris
