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.

I am not able to work with my keyboard function keys and num keys and function keys . but the the touch pad key is onlyworking .please send a solution to unlock the keyboard. hp pavilion g6-2102tx

Examine your keyboard to ensure your "Number Lock" key is not activated. This activation is indicated by the key being lit up. If the key is activated, press it to deactivate the lock. The number lock key will deactivate an entire segment of your keyboard

Start, click Run, and type regedit to open the Windows registry editor. In the registry, open the below folders.

Control Panel\
Within the keyboard folder, you should have a string value named "InitialKeyboardIndicators" with a value of 0, 1, or 2. Below is the explanation of each of these values.

0 = Num Lock is turned OFF after the logon.
1 = Disable Num Lock.
2 = Numlock is turned ON after the logon. Hope this helps.

How do i turn on the keyboard backlight on my toshiba satellite p200-1fc laptop?

Hi registrat342,Look on your keyboard & there should be 2 pictures that look like a sun on your function keys and 1 that is next to those but it has eyelashes and a box under it. Every keyboard might differ-but hopefully you get my point-as in 3 total 1st=dimmer, 2nd=brighter & 3rd would be the backlight. With mine-all I do is click it. Yours might be a little different. Hope that helps. Sherry

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.

Why cant i get my question mark symbol working agian??

This is most likely a keyboard failure, but it could also be that the rubber depressor that actives the key is stuck, out of place, or dirty. Take the malfunctioning keys off, be careful and try to remove only the key, leaving the retainer on the board. Check the depressor to see if it's depressed or shifted out of place, then take the depressor out and clean the contact point on the board and the contact point in the depressor. Put it back together and try it. If the problem persists, then the keyboard is faulty and will need replaced.
