I too have a HP nx7400 laptop and suspend to RAM/Disk does not work at all.
My model is EY252ET#ABU Intel CPU T2400 1833MHz Processor Stepping 8 Cache Size (L1/L2) 64/2048 Kb Memory Size 1024 Mb ROM Date 10/23/2006 ROM BIOS version F.08 I am running fiesty with kernel 2.6.20-11-generic My suspend (to RAM) symptoms are exactly the same as those already described. When I suspend to disk (hibernate) the laptop is locked and I have to enter my password to get back into the system (as if my password protected screen saver activated). I then get a "speech bubble" message stating that 'HAL failed to hibernate'. -- Suspend to RAM does not work well on HP notebook nx7400 in feisty https://launchpad.net/bugs/81767 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
