Thanks for coming back to me on this. I have now managed to sort this out - inspired by your response I discovered that at the last update my existing menu.lst had been replaced. CPU scaling is an issue with this machine, and the helpful guidance at https://wiki.ubuntu.com/LaptopTestingTeam/HP2133 suggested that the fix is to incorporate "acpi_osi="!Windows 2006"" in the kernel line. I had this previously but when my menu.lst was replaced this was lost - I have put it back in and it now seems ok.
The reason I thought this was a bug is that at an earlier kernel update despite the modification to the kernel line it still didn't work, and forum traffic indicated that I was not the only one with this problem. However a later update sorted this - I just thought that the same thing had happened again. Of course a fix which does not involve delving into startup files would be nice! Many thanks for your interest, and if you would like any more information which might lead to a permanent fix please let me know.

I cannot reproduce in my system, scaling works perfectly. It would help if you could provide more information about your system, and if any customization was done to it to alter the behavior.

Status in Ubuntu: New Bug description: I have just updated to Ubuntu 9.04, kernel 2.6.28-14-generic and on startup it reports that CPU scaling is disabled. This happened on the last kernel update and was fixed some while later - I would have thought that they would have got it right this time! Machine is a HP2133 mininote - cpu scaling is rather significant since this has a miserable battery life at the best of times! -- CPU scaling disabled https://bugs.launchpad.net/bugs/408303 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
