SpeedStep in a similar Dell C800 cannot be enabled in Edgy. Most of the CPUs that were shipped with the C800 do not have SpeedStep built-in, so the 1 GHz Coppermine CPU is a corner case in this laptop model.
Given that SpeedStep is not properly supported on the Dell C800 even in Microsoft Windows, this ticket is a non-bug that should be closed. The issue is just a hardware limitation. -- no speedstep for PIII Latitude C800 https://launchpad.net/bugs/36604 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
