There are 3 switches that seem to be related to it: Processing Speed: High/Low CPU Sleep Mode: Enabled/Disabled Cooling Method: Battery optimized/Performance/Maximum Performance Eventually the option: Device Config.: All Devices/Setup by OS may have something to do with that, but I think every BIOS does there what it wants. I tried every possible configuration and made acpidump's, but none worked with cpufreq. Here's a snippet from Toshiba.com BIOS changelog: Change History Version 1.50 09-29-2005 o Applied an Intel-required Pentium-M update. o Re-packaged on 2004-11-30. No BIOS code is changed. If you have already installed BIOS v1.50, there's no need to reinstall. That could have been it. Maybe I should try to downgrade to V1.40 if possible, but I first have to make sure that this doesn't break anything and if this is supported.
