I haven't tried this, but the easiest way that I can think of is to hard reset the device, choose "no" to restoring the back-up, then just immediately creating a new back-up of the currently empty UX (preferences/powersaving). This should replace the old back-up file with a new back-up file that has no information in it. If you go into the advanced mode in the built-in powersave utility you can go into the menus and choose the option to erase the backup currently in the backup flash.

Not possible with the Nokia N-Gage or QD, but the newer phones such as Nokia 3230 and N70 incorporate this feature.

This is based on the Brightness setting in the control panel (in the Screen option). Depending on the amount of light available, the chumby screen automatically gets brighter or darker. Also, blocking the light sensor on the top left corner of the frame can cause the screen brightness to change.

It most certainly ***IS*** possible to adjust the brightness of the backlight. It's in device settings - display - brightness. Then simply click and move the slider. It's a great way to extend battery life -- reduce screen brightness, or turn off the backlight completely and just view the LED without the backlight.

No. It does have a reflective backing to the screen, though, which helps with visibility. However, there is no way to see the screen in total darkness.

In a grayscale image, each pixel value represents what is loosely called brightness. However, brightness is defined formally as the attribute of a visual sensation according to which an area appears to emit more or less light. This definition is obviously subjective, so brightness is an inappropriate description of, or metric for, image data. Grayscale image data is normally based upon luminance. Color image data is normally based upon tristimulus values.

Black characters against a light gray background are often easiest on the eyes for long periods. Its suggested that contrast and brightness should be adjusted to create the brightest screen without blurring.

Press Top menu -> More... -> Settings -> General Settings -> Brightness day or Brightness night.

Slide the bar left to make the screen dimmer or right to make it brighter. The light level is the amount of light your chumby currently detects through the sensor in the top left corner of the frame.

least two companies offers replacement LCD backlights for synthesizers. A reader of this site had a problem with one of them, so I have removed their link. I don't have any direct experience with the remaining company, but I'm sure that they would be happy to answer your questions:

I think they are about the same, at least when I put my T3 side-by-side with my partner's Z71, they look the same to me. I just got a chance to compare all current palm pda screens at officedepot. The Zire71 and TE look like they have the same screen. The T3's screen is a bit dull compared to those 2 - at 100% T3 looks like the TE around 60-70% brightness. The T3 is slightly brighter than my NX70V. I just got a chance to compare all current palm pda screens at officedepot.

By default the Backlight on the keypad is associated with the clock on the phone and turns on between the hours of 5pm and 5am.

Cardio's LCD display has a backlight that lights up as soon as you hit the screen. It turns OFF after being idle for 1 minute when in direct command screens and after being idle for 15 minutes when in programming screens

Yes. The LCD will be clearly visible in the dark by activating the backlight by pressing Button 3. The backlight will illuminate for 3 seconds and then turn off automatically.

Just like handheld devices and unlike the GBA, gameTab is also powered by the backlight! Just press spacebar and turn on the lights to play in the darkness!

The Logitech Quickcam has a software video driver. When the preview screen of the Quickcam is not visible, the driver software supplied by Logitech is not invoked. This means that if the Quickcam is configured for auto-brightness, if the preview window is not shown the auto-brightening will not happen. The preview window is not visible if Webcam32 is minimized, obscured by another window or hidden by a screen saver or simply switched off.

Press some of the buttons on the connected device itself to make sure that it is functioning independent of the On-screen Remote. (Some devices cannot be operated, or can only be partially operated, by the On-screen Remote.) The On-screen remote function supports AV players from most major brands. It is possible that the AV player you are trying to connect is not supported. Move the device's infrared receiver away from any bright light, such as a fluorescent light or direct sunlight.

You can access the guide by pressing a button on your remote control, then you can navigate around the guide using the arrow buttons on the remote. The guide lists all DIRECTV® programming with descriptions of most programs. The on-screen program guide lets you look at program listings up to 36 hours ahead.

A Screen Number gives you your own personal phone number and voicemail. You can create a personalized greeting in your own voice. Any voicemails received will be forwarded to your email address as an .mp3.

Yes, just switch the player to its Hold position and the backlight will go off. This is a good way to preserve battery life.

You can use All-In-One Torch (requires Python to be installed) or S60SpotOn or SmartLight. All are free.

According to the Society of Motion Picture and Television Engineers (SMPTE), the generally accepted standard-setting organization for the industry, films are to be projected at a brightness level of 16 footlamberts (+/- 2 footlamberts). There is no standard for screen gain, and it varies substantially from theater to theater (from 1x to 3x is common). Screen gain deteriorates over time, and thus requires that screens be replaced periodically.

Yes, there is an intelligent light sensor in the LCD TV that adjusts the screen brightness to match the ambient light in a room.
