This is a known problem with a number of HP laptops. For some bizzare reason, the hardware appears to get into a bad state if it is shut down with the psmouse driver loaded.

I've created a workaround, but putting a "psmouse" script in /etc/init.d (attached), and then setting it to execute at the appropriate runlevels with "update-rc.d psmouse start 10 2 3 4 5 . stop 01 0 1 6 ." I also added "psmouse" to the "STOP_SERVICES" variable in "/etc/default/acpi- support", so the module also gets unloaded on suspend. ** Attachment added: "script to remove/insert psmouse module" http://librarian.launchpad.net/4930477/psmouse -- HP Compaq nw9440 - power manager problem https://launchpad.net/bugs/53059 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
