Submit FS#9890 by Boris Gjenero. Enabling option for iPod Video to shut down LCD and BCM (controller) after backlight was switched off. With this option the user can decide whether to keep the transflective LCD switched on (e.g. during daylight use) or to switch it off (to save power). The power saving is extreme and increases the battery runtime by far (measured >30%).
