I believe I'm seeing the same symptoms on an HP nc6400, bios F.05. I can't try other bios revs, since F.05 is the only rev that supports my Intel T7200 CPU.
For me, 'lshal -m' also shows no changes during hibernate and restore (aside from displaying the network devices). Please let me know if I can provide other information that would be useful. $ uname -a Linux mblakele-lt 2.6.17-10-generic #2 SMP Fri Oct 13 15:34:39 UTC 2006 x86_64 GNU/Linux $ apt-show-versions hal hal/edgy uptodate 0.5.7.1-0ubuntu17 -- battery info does not change after hibernate (HP nw8240) https://launchpad.net/bugs/63123 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
