How to set hdparam idle time?

Subjet. how to setup HDD sleep timeout? I’ve found that it should be in /etc/laptop-mode/laptop-mode.conf but the file not exists in netrunner 13.06.

You need first to install the laptop-mode-tools.

But is there another way? I’m not sure how to configure that. Also seems that laptop-mode-tools is overwhelming for just hdd mode sleep.
