I was confused too, Ranxerox, but just the lines with ## are real comments, lines with a single # are used by the interpreter.
So the procedure that worked for me (ThinkPad X31) is this: 1. Backup "/boot/grub/menu.lst" 2. Open "/boot/grub/menu.lst" in an editor ("sudo gedit /boot/grub/menu.lst") 3. Change the line "# defoptions=quiet splash" to "# defoptions=quiet splash acpi_sleep=s4_nohwsig". These are the default options for each kernel in the boot menu. 4. Run "sudo update-grub" 5. Reboot and test I would not advise to update the BIOS, because, as for me, my wifi-card would not work anymore (my BIOS is hacked, because IBM implemented a whitelist in the BIOS, so only som wifi-cards are working). -- Hibernate fails on Thinkpad T41 https://bugs.launchpad.net/bugs/282220 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
