I don't have much to add but I have the same problem with my TP T42. If I boot without ac and check the the cpuinfo it will say it is running at full speed (1.8 Ghz). It feels like 600 Mhz or slower from some compile tests I have done.
If anyone has a suggestion I would love to hear it. Andrew On 8/11/06, Will Briggs <[EMAIL PROTECTED]> wrote:
G'day all, Having an interesting phenomenon when I boot my Dell Inspiron 6400 to linux without AC plugged in. The boot process is as slow as a dog, all the fans are maxed "on", and cpufrequency shifting gets stuck at 1 GHz like the governor is not working (and the slowness is more than what the cpu frequency shifting would cause). However if I boot with AC and then unplug it everything works well under battery - cpu steps up and down with demand, fans behave properly etc. I wondered at first if the BIOS switches stuff off under battery so that various modules don't load or something but there's nothing obvious in dmesg and lsmod looks fine - and I've check out BIOS settings to see if there's anything - and there isn't. Any clue where to begin diagnosing such an issue? W. -- [EMAIL PROTECTED] mailing list
