Third function keyboard


The purpose of a laptop's function key is to activate the secondary function of any dual-purpose key.

The function key can accidentally be locked into place if you hit the wrong combination of keys so that all of the keys only perform their secondary function.

The exact process for unlocking the function key will vary depending on the make and model of your laptop and whether you have recently used an external keyboard.

1
Check the manual that came with your laptop and locate the section on the function of each keyboard key.

Open a Web browser and navigate to the support section of the laptop manufacturer's website if you do not have the manual that originally came with your laptop.

Use the drop-down menus on the support page to choose the specific product line and then model of your laptop.
2

Click on the "Product Support" link and then navigate to the "Manuals" section of the page. Click on the link to open a PDF version of the manual for your laptop.

Browse down to the section about the functions of the keyboard keys.
3

Find the sequence of keys you need to press to unlock the function key on your laptop.
Press and hold the function key on the keyboard and then press the other keys required to unlock it.
4

Try using the most standard keyboard combinations if you don't have the manual or it does not give any information about the function key.

Press the function key and then the shift key and see if it successfully unlocks the function key. Attempt using the other standard keys in conjunction with the function key, such as the "F11," "F12" and "Ctrl" keys.
5

Plug a USB keyboard into the USB port on your laptop if you have recently used an external keyboard with the laptop.

Check the light above the "Numlock" key on the external keyboard and see if it is turned on. Press the key and make sure the light is turned off and then remove the keyboard to unlock the function key.

List of all keyboard symbols


Hi, many symbols are found using Shift key plus a number. Some symbols are found with the AltCar key (next to the space bar) with a number Another way, is to use the table of caracters ASCII found on Internet: you use the Alt Key with the 3 digits number that matches the caracter you want. I include the link for the table.

My daughters key board on her lap top has started to act crazy you can't backspace and you can not type double letters you have to wait a second for it to keep typing any suggestions


First, try to connect an external USB keyboard & see if it will work fine.
If the external USB keyboard works fine, then you will need to replace your laptop's keyboard, as there is almost nothing that can be done to fix a defective laptop keyboard.

I have a Dell Inspiron laptop, and certain letter


This could be a possible hardware issue. You can try to use an external USB keyboard and check if the keys are working or not. If you do not have an external keyboard, you can try to use the onscreen keyboard. To do this, go to start>programs>accessories> accessiblity and then choose on-screen keyboard. Open a notepad and try to use the keys which are not working using the onscreen keyboard. If onscreen keyboard works fine , then you need to get the keyboard replaced.

My shift key will not work for all letters, forcing me to use caps lock by pressing it before typing the letter and immediately after typing the letter. any suggestions?


This can be either a bad keyboard or a bad system board. There's no way to tell without swapping out the keyboard. Laptop keyboards aren't hard to replace and cost about $50-60. If that does not resolve the problem, learn to live with it because a replacing the system board generally isn't worth the cost unless you have it covered under warranty.

I have a Panasonic Toughbook CF-18. The keyboard


Connect an external keyboard to your laptop. If the external keyboard works properly that means the keyboard of your laptop is defective and you have to replace it. If you get the same problem with the external keyboard reinstall your operating system (it could be a virus).
