The brightness of the screen is a tricky setting. Depending on the situation, you may want it to be very bright or very dim. You may also want to keep the screen on for a long time without wasting too much valuable battery power by having it set to the highest brightness.

By default, PalmOS devices only allow you to set a fixed brightness and you will have to re-adjust the brightness whenever you feel it is required. But by using Energy Dimmer, you can switch between brightnesses much more easily ? plus you will have additional features like screen dimming (hence the name) and adjustable auto-off values.

Using Energy Dimmer will give you the flexibility to manage the brightness quick and efficient by using profiles. A profile ...

... allows to set a brightnes ... allows to define if and after how many seconds of inactivity the screen should dim ... allows to define to what level the screen should dim ... allows to define individual auto-off times in the range of seconds The brighter the screen, the more power is consumed. Switching to a profile with the perfect match for your current situation will allow you to only consume the power that you really need, allowing for a potentially larger runtime on one charge.

Requirements Energy Dimmer requires:

PalmOS 5.x a colour PalmOS device (more specifically it currently supports the Tungsten C, T, T2, T3, T5, TX, E, E2, the LifeDrive, the Treo 600, 650 and 680, the Zire 71 and 72 as well as Sony Clie NX, NZ, TG, UX, TJ, VZ and TH series and also the Garmin iQue 3600 as well as the Tapwave Zodiac). For more details, please refer to the manual.

Important notice: On some devices Energy Dimmer allows to dim the brightness below what the device's own brightness slider offers. This is the case if the device's brightness slider does not make use of the full range of brightness values that the PalmOS-interface allows for. Devices where this happens are most notably the Tungsten T, T2 and E as well as the Zire 71.

On newer devices like the TX, LifeDrive, E2 and Zire 72, you can not achieve this side-effect of dimming lower than originally possible by using Energy Dimmer. Please keep in mind that it is not the task of Energy Dimmer to do that. If you really need this feature, you could try out an application called Brightness Fix that is available at http://www.palmpowerups.com and accesses the hardware directly to extend the range of brightness. Energy Dimmer will be able to make use of this new range. Do note, though, that we do not endorse this direct access, and you will use this on your own risk. Energy Dimmer itself will continue to only use the OS provided capabilities.
