hi all. sorry for my bad english i had same problem with my laptop Medion MIM2080: no power management, laptop screen stay tuned on in hibernation and shutdown.
i tried to remove spash and Quiet, but nothing changed. then i remember that some one who had same laptop said to remove ACPI=OFF i removed it, and i pushed "b" to reboot, and everything went OK: -Battery has been found and managed by Ubuntu -hibernation OK -shutdown OK but still have wifi (not found even with ndiswrapper) and graphic card problem (no 3D at all) -- Jaunty & Interpid: won't power off on shutdown or reboot https://bugs.launchpad.net/bugs/326988 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
