Hello, In my Thinkpad T60 and using Powertop I don't see that I have a C4 state. Should I setup something? T2400 doesn't have C4? I found PowerTop in Thinkwiki webpage: http://www.linuxpowertop.org/powertop.php VERY interesting program! I will have some fun with it soon :-) Thank you, -- Carles Pina i Estany GPG id: 0x8CBDAE64 http://pinux.info Manresa - Barcelona
