    Hi emeraldseadi , I want to help you with your problem, but I need more information from you. Did you try pressing the same key combination?

    Is it Fn+Alien FX key?

There should be a function key to dim and brighten it.

Dimming backlight on ec-ws115

Yes. Look for a setting related to the Fn key on the lower left corner of your keyboard, and a similar key on the top row of Function Keys, on which there will be an alternate text in the same color as the Fn key at the bottom.

They are keyed that way so that you must press down on the Fn key first, then the Function Key on the top row which has the text to compliment the action you want to take. Together, they will help you to increase, or decrease the back lighting on the laptop.

Probably there are two separate keys, one to dim it and one to brighten it.

Either of both require you using the Fn key at the lower left of the keyboard.

The back light is out, how to turn it on?

1.Check your monitor brightness setting. Occasionally, the monitor brightness can get accidentally turned all the way down. This will result in a completely dark laptop screen that appears to lack a backlight. Adjust the monitor brightness via the dedicated brightness keys at the very top of your laptop's keyboard.

2.Toggle the backlight back on via the keyboard. This is accomplished by using the "Function" key, which lies near the bottom left of your laptop keyboard and is marked "Fn." When pressed in conjunction with one of the "Fx" keys on the top row of your keyboard, you can toggle the backlight on and off automatically. There is an "F1" key, an "F2", and so on. The exact key to press simultaneously with your "Fn" key will vary by laptop model, so consult your computer's user manual. You may have accidentally toggled the backlight off and simply need to toggle it back on via this key function.

3.Prepare to operate on your laptop if you cannot toggle the backlight back on. Shut down the laptop. Disconnect the AC adapter cord from the back of the computer, then close the display and turn over the computer.

4.Remove the battery. The battery on most computers is at the top of the laptop's underside, although some computers may feature the battery in a bottom corner. The horizontal outline of the battery will be clearly visible all the same. Beside or just beneath the battery will be a battery-release latch. Slide this to disengage the battery.

5.Turn the laptop back over. Open the display.

6.Observe the bezel, which is the perimeter that runs around the display. There will be a number of rubber caps that exist on the bezel. The exact number will vary by laptop model. Use the tip of a flat-head screwdriver to pry under the caps and pop them off.

7.Remove the screws under the laptop bezel's caps with your Phillips screwdriver.

8.Work around the bezel's perimeter with your fingers and pry the bezel completely off.

9.Look at the bottom of the monitor assembly. A thin inverter board will span horizontally across the screen's bottom. There is a connector on either end of the inverter board. If the right cable is loose from the right connector, lift up on the connector and slide the cable back in. This will restore the laptop's backlight.

10.Replace the bezel and the bezel's screws. Reinsert the battery and power on the laptop.

How brighten the screen?

Look on your keyboard on the "f" keys (f1, f2, etc...) for a symbol that looks like a sun or shining light. Something that would indicate brightness. Now, hold down the 'fn' (function) key on the bottom left of your keyboard and then press the backlight key you just found.

Instead of getting the @ symbol when I press shift +2 i get "

you need to hold down ctrl and function on the left side of your keyboard, and then hit the shift key on the right side of your keyboard. Then let go of right shift while still holding down the control and function keys, and then hit right shift again.

these blue keys are french keys. if you change your keyboard settings to english US or UK, it will get rid of the blue functions, but for some reason, they tend to turn themslves back on again after time. Most likely due to automatic updates followed by an auto restart. Also, I find that the issue only arises if I am in my hotmail issue in Word docs.

Keyboard is off?

If it's a PS/2 keyboard (round connector, about the diameter of a pencil, check to see if you're plugging it into the keyboard port. It's easy to plug it into the mouse port by mistake.

Another thing to try is to turn off the PC, plug the keyboard in, and turn back on so it will initialize on bootup.

If it's USB, it should be recognized immediately if the keyboard is functional.

My cf30 rubberized keyboard functions but will not backlight. Is it malfunctioning or is there an option somewhere to activate it/turn it on?

There is a function key combination that turns on the back light, I believe it is Fn+F12. Hod down the FN key and press F12. The first press turns the backlight on full brightness and succesive presses dim it until it is turned off.

I'm sorry but I don't have my CF-30 in fromt of me at this time, it could be Fn+F10. There is a blue symbol on the correct key and I believe it looks like a light bulb.

If this doesn't work, you may need to have a hotkey driver installed.

Is the caps lock light illuminated? If so, you might have to hold shift and hit caps lock to turn off the caps lock. This is an option for old typists who came from manual typewriters that you might have turned on by mistake.
