My fn key is working backwards how to fix


You need to restart (to enter in BIOS) your computer to change this.
While first black screen comes Press F2 or del (this may differ in your laptop).

If you post exact type of laptop i can see what bios you have, but you can look for yourself for it.

If a bios screen (may be unknown to you) appear then find Function Key Behavior select Multimedia Key First or Function Key First.

Function Key First

This is the default option. Press any function key to perform the associated function. For multimedia action, press Fn + the required multimedia key.

Press and release the “CANCEL” button as many times as necessary, so that, either the “Welcome to Photosmart Express” screen appears, or, the “Ink System Failure” screen appears.

DO NOT TRY TO PRINT AT THIS STAGE.

Using the Power Button, turn the unit OFF and unplug the power cable from back of the printer and wall outlet.

Wait 30 seconds for the power to get discharged and then plug the power cable into the wall outlet first and then into the back of the printer

Turn the unit on. The printer may display the message “USE POWER BUTTON TO SHUTDOWN THE PRINTER” followed by “PRESS OK TO CONTINUE”.

Press OK. The Printer will start the “ONE TIME INK INITIALIZATION PROCESS”. Allow this process to complete and do not interrupt. Once the initialization process is complete, the printer will print out a Diagnostic Page.

To verify printer functionality print a SELF TEST PAGE. If SELF TEST prints, then printer is ready for use or Software Installation.

Press f1 f2 continue


For what purpose are you pressing the F1 key. The function keys may have different uses depending on the computer. When combined with the Fn key of a laptop they may also do certain actions. You should read the manual of your laptop to find out about the function keys.

Unlock number lock


On a laptop, the "Num Lock" key has a function slightly different than the one it performs on full-d desktop keyboards. Activating "Num Lock" on a laptop usually transforms a set of central keys, including many letters, into number keys, allowing typists used to entering numbers on a keypad to type efficiently. While on desktop keyboards "Num Lock" usually has a dedicated key, on laptops it often shares a key with another function on MacBooks, for example, it shares the "F6" key and you must hold down the "Shift" or "Fn" key to activate it.

Look for the "Num Lock" key on your laptop's keyboard. This is usually near the top of the keyboard. If the key says nothing on it except "Num Lock" if that's the only function the key performs you can just press it to activate the lock; a light will probably go on somewhere to indicate that "Num Lock" is on. If the key has multiple functions, you'll have to hold down a different key while pressing it. Hold down "Shift" and press "Num Lock" if the writing saying "Num Lock" appears above some other writing on the key, the way various symbols appear above the numbers on the keyboard's number row. Hold down "Fn" and press "Num Lock" if the writing saying "Num Lock" appears in a different color often light blue that's shared by the "Fn" key.

How i can enble function key


HP laptops have the ability to lock the blue special function keys on, making numerical data entry easier on laptop models that do not have the room for dedicated numerical keypads. Because the key combination to lock the function keys is so simple, however, it is easy for those who wouldn't normally use this ability to do so accidentally. When the function keys are locked, pressing certain keys will result in numbers being typed rather than letters. Unlock the function keys to alleviate this issue.

Press the "Fn" and "Num Lk" keys on the keyboard simultaneously. The "Number Lock" indicator light should turn off, indicating that the letter keys will once again type letters when pressed. This combination should work on the majority of recent HP laptops. If it does not, try one of the alternate key combinations in this article's remaining steps. Press the "Fn" and "F11" keys simultaneously, then attempt to type a letter. If the combination does not work, continue to the next step. Press the "Fn" and "Scroll Lock" keys simultaneously, then attempt to type a letter. Continue to the next step if this does not work. Press the "Fn," "Scroll Lock" and "F11" keys simultaneously.

How do I enable a compaq laptop's keys


Compaq Presario computers provide users with a row of function keys for added keyboard functionality. Function keys can serve a dual purpose as well.
Function keys are located at the top of Compaq Presario keyboards.
By learning how function keys work on a Compaq Presario you can take advantage of time saving keyboard shortcuts.Purpose
Use function keys to access menus, save changes and create shortcut keys.
Various applications, including Microsoft Office, allow you to select a function key as a shortcut key for running specific tasks. These settings are usually found under the Tools, Settings or File menu.
Each Compaq Presario computer has twelve function keys.
The most common used keys are "F2," "F8," "F10" and "F12."
The first three are used mainly to access and use the Compaq BIOS. "F12" is used to access a set of run from options during the boot process.

How to Access
Access function keys on a Compaq Presario by pressing any of the keys on the top row of the keyboard. Access the key's dual purpose by first pressing the "Fn" key located on the bottom row of keys.
Use function keys as shortcut keys by pressing them anytime while in the desired application. Remember, you must set them as shortcut keys first.
Note that some programs may already have certain function keys set as shortcuts.
Open menus and view the shortcut keys beside each menu item before setting your own shortcuts.


Dual Uses Each function key has a dual use. Press "Fn" plus the desired function key for the key's other use.
Below each function number is a small picture within a square or rectangle.
This dictates the dual use. "F1" opens help and support. "F2" serves as a printer shortcut.
Open your homepage by pressing "F3."
If you use dual monitors, switch between monitors by using "F4." "F5" puts your computer in stand-by mode.
Quickly lock your computer by pressing "F6." "F7" and "F8" adjust the screen's contrast.
Play and pause your music in Windows Media Player or other default media player by using "F9."
Press "F10" to stop playing media. Skip ahead or rewind media by using "F11" and "F12."

Other "Fn" Keys

In addition to function keys, the "Fn" key is also provides other keys with a dual use.
Any key with a small square on the key has a dual purpose such as the "scroll," "insert" and "delete" buttons.
Since laptop keyboards have no number pads, certain keys serve as the number pad by pressing the "Fn" key.

How to fix E1 error on samsung ER 5140


E1 is just operator error, it normally occurs when the wrong keys are pressed or the machine has got itself into a bit of a loop. At exactly which point does the message appear? is it when you press a certain key?

The first thing to try is an initial clear:

Turn the key to P
Press and hold SUBTOTAL
Whilst continuing to hold SUBTOTAL turn the power off... then back on
Continue to hold SUBTOTAL until the receipt stops printing
Turn the key to R and give it a test.

My son has a TI-84 Plus calculator and it is completely frozen. There is a message on the screen that reads " RAM cleared". Below that message it says "Press ALPHA F1-F4 to locate shortcut menus" but it...


The calculator OS has been upgraded to the version 2.53 MP.
For this version, whenever you remove batteries (or replace them) and turn calculator ON, you are reminded to Press [ALPHA][F1-F4] to locate Shortcuts Menu.
The calculator also asks the user to press either
[1:Do NOT show Again]
[2:Continue].

Here is what these cryptic messages mean.

Certain functions implemented on the new OS are available by pressing the [ALPHA] key followed by F1, F2, F3 or F4.
Since you may forget how to get to them, the calculator gently reminds you that there are other functions accessed only by pressing the [ALPHA] key.
It also gives you the option to flash the reminder every time the calculator memory is reset (CONTINUE) or NOT to SHOW the REMINDER again.

Usually after the RAM cleared message, press [2:Continue] or any other key but [1: ] to keep being reminded how to access the new functions.
Once a key is pressed the screen is cleared and you have the solid blinking cursor.

Cant get the at button to work even by pressing shift or not,every other key function works.


You may have a bad key, or a key with something under it.
Try this:

Turn the netbook upside down so that the keysj face the floor.
Bang on the back side that way you would to burp a baby.
Then, take a vacuum cleaner and **** out the spaces between the keys.
If this doesn't work, you may have to make an @ symbol manually by using the ALT key. (ALT plus 64). This should work in most Word Processing programs.
  1. Make certain that the Num Lock key has been pressed to activate the numeric key section of the keyboard.
  2. Depress the Alt key.
  3. While the Alt key is depressed, type the proper sequence of numbers (on the numeric keypad) of the ALT code from the table above.
  4. Release the Alt key, and the character will appear.
  5. On a laptop computer, there usually is no numeric keypad. So, instead, depress the Fn (function) key, then the Alt key, then the numerical code sequence. The numbers are on the fronts of certain keyboard keys: M=0, J=1, K=2, L=3, U=4, I=5, O=6, 7=7, 8=8, and 9=9.
