I can confirm this. I also noticed that my laptop's (IBM Thinkpad T23) HDD was powering off after 5 seconds. I took a look in /etc/acpi/power.sh and I saw that the power management settings were hardcoded.
The settings for HDD's power management can be configured in /etc /laptop-mode/laptop-mode.conf so there is no need to configure these settings in /etc/acpi/power.sh. The HDD power management settings hardcoded in /etc/acpi/power.sh should be completely removed since this script runs laptop-mode that configures HDD power management. -- Hard drive spindown should be configurable https://launchpad.net/bugs/17216 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
