I see from your BootDmesg.txt file: [ 0.000000] Kernel command line: BOOT_IMAGE=/boot/vmlinuz-2.6.31-17-generic root=UUID=1257db60-9fbe-4a1c-aad6-9303cbff6640 ro quiet splash noacpi
The noacpi option here is not the default as far as I know, you did add it? >From http://www.kernel.org/doc/Documentation/kernel-parameters.txt : acpi= [HW,ACPI,X86] Advanced Configuration and Power Interface Format: { force | off | ht | strict | noirq | rsdt } force -- enable ACPI if default was off off -- disable ACPI if default was on noirq -- do not use ACPI for IRQ routing ht -- run only enough ACPI to enable Hyper Threading strict -- Be less tolerant of platforms that are not strictly ACPI specification compliant. rsdt -- prefer RSDT over (default) XSDT See also Documentation/power/pm.txt, pci=noacpi Well, I am not a developer, just a bug triager. But it looks like you are saying by this noacpi option, not to use Advanced Configuration and Power Interface (ACPI) which seems likely not to help suspending. Now that we are using Grub2 rather than plain old grub, I think I am a bit lost as to where it must be changed. But I guess you can test different values by pressing 'e' to edit the command in grub menu before doing Enter. Also, although it does make sense for me to update BIOS, it can be risky (especially if current goes out during the procedure)... so you have to know and accept the risk. ** Changed in: linux (Ubuntu) Status: New => Incomplete -- HP DV5 - Can't suspend, get a Lock Screen instad of suspend https://bugs.launchpad.net/bugs/501323 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
