Lenovo Notebook V490U s notebook keyboard cannot enter text, including numbers

Dear Lenovo users, it is recommended that you enter the safe mode to test the use of the keyboard, the safe mode is used normally, there is no problem with the hardware, it is generally caused by software conflicts, consider uninstalling the recently installed software. If you can't use the keyboard in safe mode, it's usually a keyboard failure. And if the external connection is normal, it is very likely that the keyboard is faulty, it is recommended that you go to the local Lenovo service station to test it, and the service station staff will solve the problem for you.

The fn key is locked, release the fn key to try, go to the Lenovo official website to see how to remove this notebook, do not rule out the problem of a bad notebook keyboard, and you can also replug and unplug the cable. However, this is a technical job, so it is recommended that you go to the computer to shop around.

The solution to the Lenovo notebook keyboard that can't enter numbers:

1. Click [Start] - [Run], enter "regedit" and click the enter button 2. Then find the Control Panel under hkey current users in the registry, find the keyboard item in it, and left-click.

3. Double-click [InitialKeyboardIndicators] on the right side and set the key value to 1, this method is to memorize the state of numlock before shutdown, that is, it is on before shutdown, and the lock is also enabled by default when you boot it again.

Press and hold the fn key + nmlk key in the lower right corner to switch to the commonly used keyboard, if you want to use which number keys or shortcut keys can press the fn key + any key you want to combine.

Open the numeric keypad, find the numlock key (or similar), and press it to switch to the alphabet input state.

You have the numeric keypad enabled, there is a numlk key in the upper right corner of your laptop keyboard, hold down the fn key in the bottom left corner, and press the numlk key again

Hello, you can switch it by FN+NUMLK keys.

This is the blue key function of fn, which is used to enable the blue markings on some keys. Some are power management (a battery graphic) and some are hibernate functions (a moon graphic), which you can find in your computer's instruction manual.

As for turning on or off your numeric keypad, you have to find which key on your computer has the blue word nmlk (the meaning of the number key, maybe yours is num), my thinkpad is scrlk key with this incidental function, then press and hold fn (bottom left), and then press the key you find to turn on and off the number key.

Dear users, hello!

It may be that you have accidentally turned on the numeric keypad, please press the fn+nmlk key to turn off the numeric keypad, it should be normal.

Have a great day, thank you!

There is an FN button in the lower left corner and an ins button in the upper right corner.

Well, fn key + ins key.

The problem of fn in the lower left corner and nmlk in the upper right corner is solved.

The keypad is turned on, and FN+F8 is turned off.

Laptops don't have keypads, so some of the letters are locked and you can only enter numbers.

1. Press and hold the fn button in the lower left corner.

2. Press the num lock on the upper right at the same time, the locked keyboard will be unlocked, and it will change back to letters when you enter it again.

The solution of changing letters to numbers on the notebook keyboard (fn+numlock number lock key).

However, due to the different designs of various types of notebooks of notebook manufacturers, the way to close and open the keypad is also different, but almost all of them are fn key + number lock key, or shift key + number lock key.

HP DV Series FN+NUMLOCK key (NUM and SCROLL on the same key)

HP Compaq CQ Series FN+SCROLL key (the key after F12).

Dell Inspiron Series FN+F4 key (there is a small lock in the lower right corner of the F4 key icon, and there is a number 9 in the lock, which is the num key).

Dell Vostro Series FN+Numlock key.

IBM Shift+NumLock.

Lenovo ThinkPad Series FN+ NMLK Scroll key (top right, two functions together)

It may be that you have mistakenly pressed the switch key of the keyboard, switched the laptop to numeric keypad mode, and pressed the FN+NMLK key at the same time to switch back.

That's when you turned on the keypad function with a key combination. Just turn off the keypad function.

How did some of the keys on the notebook keyboard turn into numbers? Is the keyboard broken, or is the system poisoned?

This is not a problem, it is a special feature of the notebook's keyboard. Find the fn key on the notebook, find the keycap with the word num written on the keyboard, press and hold fn and don't let go, and then press the keyboard with the word num written on it, so that you can realize the switch of the hidden numeric keypad.

We all know that the notebook keyboard is limited by the actual size of the notebook, and it cannot be placed with many function keys like the normal keyboard, especially the small keyboard. It is almost impossible to see too many independent function keys on a notebook under 14 inches, but those function keys are not optional, so the notebook integrates the function keys on other commonly used buttons, and realizes the hidden special function through the local elimination form of the FN+ button. Although this layout design has been controversial in the industry, it has no impact on old users.

The FN key does not play an input role in laptops, it is a pure key combination like the CTRL key, the key combination composed of the FN key and other keys can be directly supported by the BIOS (this is the practice of most brands), or it can be at the software level (such as SONY's practice), of course, the most current form is hybrid, that is to say, some key combinations are directly rented by the BIOS support and can be used in any environment, Some groups require additional software support in the operating system for the bonding to take effect.

Most FN key combinations are implemented using the FN key plus the ESC or F1 F12 key, but some manufacturers (e.g. IBM, Compaq, and Sony) have some combinations with the FN key and the letter key, and most of these combinations are for the general user"Secret techniques":) we'll share these special key combinations with you below. The combination of the FN keys and the corresponding functions are generally uniform across the brand.

fn + up and down keys"adjust the brightness of the display;

You lock the number key, which is "numlk", press this key, and you're good to go.

This is the numeric keypad.

Copy is turned on Press fn (bottom left corner bai

F11 (this DU key depends on the computer model, generally ZHI is near F11, F12, or NumLock button) DAO

If you connect an external keyboard, this is because you turn on the numlock button on the numeric keypad of the external keyboard when you connect the external keyboard, and the numic keypad on the notebook's built-in keyboard will be turned on, as long as the numlock button of the external keyboard is turned off, it is normal

Dear users, hello! Glad to answer for you: just press fn+numlk(f8) to switch.

Thank you, Lenovo will serve you sincerely!!

I heard that Alienware NB uses this configuration Core i73720QM, 2GB GDDR5, DDR3-1600, M-SATA, Sound Blaster Recon3D.
