Brightness Question

Yes, you can adjust the LED display brightness on the Advance Model 3138 alarm clock. To adjust the brightness, follow these steps:

1. Press and hold the "SNOOZE/DIM" button for 2 seconds. The current brightness level will appear on the display.
2. Press the "SNOOZE/DIM" button repeatedly to cycle through the available brightness levels.
3. Once you have selected the desired brightness level, wait for a few seconds for the clock to automatically save your selection.

Note that the brightness levels are labeled as "HI," "MED," and "LO" on the clock. If you want to turn off the display entirely, you can press the "SNOOZE/DIM" button once more after selecting the "LO" brightness level.

Some TVs have an 'Auto Dimming' feature. This automatically adjusts the brightness depending on the light levels in the room. Go into your settings and check if this feature is installed and turn it off.

Try going into power option settings and taking the brightness to the max there. Start, control panel, power options, then you should see a setting for battery and for plugin. Hope this helps.

Occasionally, you may find your laptop's monitor is too dim for your liking. A normal desktop computer's monitor has an on-board menu system that lets you adjust the brightness and picture control settings as you please. A laptop monitor has no such controls. You can adjust the brightness of your laptop monitor using your laptop's keyboard.

1.Press and hold the "FN" key on your laptop's keyboard. This is the "Function" key, which operates much the same way that the "Shift" key does: It allows keyboard buttons to be used for multiple purposes. It's located in the lower left corner of most laptop keyboards, next to the "Windows," "CTRL" and "ALT" keys.
2.Look at the top row of keys on your keyboard for a key with a tiny triangle pointing upwards and the symbol of a sun on it. This is the "Increase Brightness" key. With the "FN" key held down, press the "Increase Brightness" key. On most laptop keyboards this is the "F7" key, but it varies depending on the model.
3.Continue to hold down the "FN" and "Increase Brightness" key until your dim laptop monitor has reached the level of brightness you require. A laptop monitor can only get so bright. It will stop at its highest setting.
4.Release the "FN" and "Increase Brightness" keys. You have now fixed your dim laptop monitor.

I hope you find it very helpful.

ok , you have checked the brightness settings, check battery power settings as well. you may have to do a hard reset so back up your info. If doing a hard reset, pull the battery and charge it on its own if you have a cradle. Hope this works for you

Found this in the manual:

To adjust the display brightness -

The display dims automatically to medium or low brightness, as appropriate for low light room conditions. You can adjust the brightness setting of the display for both strong light and lowest light environments, but not for the medium light setting. Turn the system off before setting brightness levels.

• In a strongly lit room, hold down CD Mode and press Volume up or down to adjust the setting between 5 and 9 (it is preset to 8).
• In a barely lit room, hold down CD Mode and press Volume up or down to adjust the setting between 1 and 5 (it is preset to 2).
• If you do not want the system to dim automatically, set both levels to 5.

Did you try to set the Backlight on in the control panel? (settings>system>brightness) The brightness is often automatically set to 0. If you did this already and it still doesn't work, probably try an email.

First, to dim/undim the screen, hold down the power button for a few seconds. A quick press will turn it on/off. Also, when dimmed, if you tap the screen, it should be fully lit. FYI...to change the brightness in either the plugged-in or battery mode, hold in the scroll dial on the left-hand side and press the navigation button (big round one on the front) either up (brighter) or down (dimmer). As for the time, tap Start >> Settings >> System (tab) >> Clock and see if your time is off by 12 hours.
