As can be seen from at least the last attachment, I have version A05. On the Dell site I see they reached version A08. However the changelogs for the newer versions don't show anything related to ACPI, so I'm not sure if that would change anything.
I'm reluctant to update because I have the French version of the laptop, and I only see English BIOSes on the site. I sent them a mail asking if that would work, but until they answer I'm stuck with this one. ** Attachment added: "lshw.txt" http://launchpadlibrarian.net/9197109/lshw.txt -- ACPI Warning: Incorrect checksum in table https://bugs.launchpad.net/bugs/133146 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
