there is one problem with one laptop. when power cable is unplugged, system works fine, but when you plug power cable in, systems gets slower. i see it while opening folder in KDE, animation becomes slower, and so folders opens slower. i played around with power schemes - nothing. it happens only in KDE(i tested with Suse, mandrake and kubuntu), but with gnome it is ok (tested with ubuntu). laptop is sony viao.
can anyone help?
