jeevesbond writes "Back in October of 2007 we discussed a bug that would dramatically shorten the life of laptops using Ubuntu. Ubuntu users will be glad to know that a fix has finally been released for Ubuntu versions 9.04, 8.10 and 8.04 (LTS). However, as this fix is not yet in the update repositories, anyone wishing to test it should follow these instructions for enabling the 'proposed' repository. Report your results on the original bug report. Happy testing!"
