SOURCE: hi i have asus g73jh I Turned off keyboard light

What you need to do in this situation is press fn + f4 a few times to get the lights to come back on (after cycling through all of the lighting modes to get back to where you started).

SOURCE: Keyboard no longer lights up

Hello,

It is possible that the connection between the keyboard and the laptop is the issue. If you can figure out how to remove the keyboard, you will see it is connected to the laptop with a flat ribbon cable. Open the plastic clip that holds the flat cable (carefully!!) and then reconnect the cable. If that doesn't fix it, you may want to contact asus to get a replacement keyboard, or just plug in a usb keyboard.

Hope this helps!

Joe

Want to turn on back lights for keyboard to see while typing in dark


I do not believe the Probook 4440s has LED lighting for the keyboard. The key combinations Fn+F2 and Fn+F3 keys at the top of the keyboard control the monitor brightness (backlight). The keyboard is spill-resistant.

You need to attach an external keyboard with backlighting or a USB light to see your keyboard in a dim environment.

I wish that I could be of more help.

Why LCD TV have No Picture only sound


Flat-panel LCD TVs have a lifespan newly approaching 100,000 hours on average. The lifespan of an LCD TV is generally longer than that of similar-sized plasma televisions. Some manufacturers even claim that their LCDs can last upwards of 100,000 hours when used continuously under controlled conditions (e.g., in a room with "standard" lighting conditions and 77&deg; temperatures throughout). Just how realistic such claims are is debatable. After all, whose living room has no windows and remains at a perfectly comfortable 77 degrees year-round? <br /> In any case, the pictures on fluorescent backlit LCD TVs will show some "wear" because they are generated by powerful lamps, which, like any lighting appliance, will dim over time and with use. The picture you see will dim ever so slightly as the backlighting bulbs dim. One other consideration is that CFL fluorescent backlighting will change colors over time. This will change the white balance on your TV and cause color calibrations to be thrown off. <br /> Therefore, the most important thing to consider when it comes to the lifespan of your LCD TV is the actual lifespan of the light source in your LCD. LCD TVs last as long as their lightsources do. So, the lightsource in your LCD TV is the critical component of your LCD display unit. Newly introduced LED backlit LCD TVs will have the best long term performance. LED backlighting is superior in that the white balance of the TV will not be affected by changing bulb color over time. It's a more consistent bulb technology and will also maintain its brightness longer. <br /> The edge lit version of LED TVs will use far less energy while local dimming LED backlighting will be more accurate and present a better picture while using more power. We believe that local dimming LED backlighting will be slightly less stable from a life span standpoint. <br /> To ensure the integrity of your lightsource for the duration of your LCD display's lifespan, you will definitely want to adjust the CONTRAST setting of your LCD TV. Too high of a CONTRAST level will prematurely age your lightsource because it will have to work harder to maintain such light intensities. Your best bet is to keep your CONTRAST set appropriately for the conditions under which your view your LCD display. Brighter ambient light levels require slightly higher CONTRAST levels, while lower ambient light levels demand less CONTRAST <br /> If there is sound but no picture, only sound it has more chances of faulty back light repairable from Service Support. <br /> Hope this helps, if so do rate the solution. <br />

Deem light in display


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.

My compaq presario lcd is working but it has no lights


If by lights, you mean the LED lights located around the exterior of the laptop (like the power light, hard drive light, etc.) then you may have accidentally switched those off.

First you need to locate the 'FN' key. On most laptops it's located on the bottom left of the keyboard, under the 'shift' key.

Next you will need to look for a symbol on the keyboard that would represent the LEDs. It's usually a light bulb, and is almost always located on the 'Fx' keys on the top of your keyboard (F1, F2, F3, etc.).

Once you have located the correct key, you need to hold the 'fn' key that we found earlier, and press the 'Fx' key that corresponds to the LED (or light bulb) button.

For example, on a older model Gateway laptop, I will hold the 'FN' key on the bottom left, and press 'F1'.

If by lights you mean the backlighting for the LCD screen, which would make the LCD screen appear very dim, then you will have to have the screen serviced or replaced.

I hope that helps, and if you have any questions, please let me know.

Acer 4520 light going dim


Normally the way it works is if you plug in your AC Adapter to a laptop the computer screen will Brighten up since its no longer running off of battery and is actually charging . The reason why it should go dim is when you unplug the Ac adapter it goes dim to save battery life and last longer. If you are getting a really dim you can check and make sure that the Ac adapter jack on the adapter or motherboard isnt loose and it could be having contact to the unit and be loose inside and every small movement causes it not to charge / charge in and out and would cause this Dim effect. Again this depends on how old the computer is and I dont really think its the LCD or backlight going bad but you can try to mess with the screen brightness and If im not mistaken on that model it should be the FN key and the Right > and Left < Key for lower and higher brightness. Give that a try and check the adapter connection and you can pin point the issue . Hopefully it doesnt come worst to worst which could be a bad LCD going bad or damaged lcd internal cable. Hope my answer helped guide you closer to a solution.

HP dv1000 monitor just stopped working.


Description During the startup or boot process of the notebook, the display is very dim and barely readable. It remains dim when it reaches the Windows desktop. Restart the notebook with AC power Perform the following steps to determine if the dim display is due to a hardware failure:
  1. Connect the AC adapter to the notebook and a working electrical outlet.
  2. Power down the notebook PC by pressing and holding the Power button for 5 seconds.
  3. Press the Power button again to start the computer.
If the display is still dim after restarting with the AC adapter connected try changing the LCD brightness. Change the LCD brightness From the Windows desktop, hold the Fn key and press the F7 and F8 keys to increase or decrease the brightness of the display. If using the function keys does not resolve the problem, determine whether the Lid Actuator switch is stuck. NOTE: The key number may vary depending on the notebook PC. The image on the key should resemble the following images: Figure 1: Brightness Level Down c00776225.jpg Figure 2: Brightness Level Up c00776226.jpg NOTE: During battery power operation, the notebook display will dim to reserve battery power. Adjust brightness control using the control panel Some notebook PCs have the ability to adjust the brightness through video drivers. If the notebook PC has video drivers with this capability, perform the following steps:
  1. Click Start , Control Panel and then double click Display .
  2. Select the Settings tab and click Advanced .
  3. If the feature is available, a tab with the video card name will be present. If it is, select that tab.
  4. Adjust the desired brightness.
Finding the Lid Actuator switch The Lid Actuator switch is a small button or switch located above the keyboard and LEDs on the right or left side of the notebook. It may also be located near the display hinges. Pressing this switch when the computer is on may turn the notebook display off or cause the notebook to enter a different power state. Press the switch 2-3 times while observing the display. If the display is no longer dim the switch may need to be repaired. Contact HP service and support for further assistance. Contact HP service and support If the display remains dim after the troubleshooting in this document it may be possible that the backlight is damaged. Please Contact HP service and support to schedule a repair
