How to unlock the computer keyboard when it is locked

1.Click: Start - Control Panel - System - Hardware - Device Manager - Keyboard (Human Input Device).

Or right-click on "My Computer" and click on "Device Manager".

When you get to this point, you will find that the driver shows a yellow exclamation mark, that is, it is not installed).

2.Click: Action-Uninstall (uninstall the keyboard Human Input Device driver)3Single-Click: Operation-Scan detects hardware changes (or restarts).

1.Restart the computer, and during the computer startup process, press the F2 key to see if you can enter the BIOS settings. If you can't enter the BIOS settings normally, it can basically be judged that the keyboard data connection is loose, and you need to send it to the local service network for testing and maintenance.

If you can enter the BIOS normally, it means that it has little to do with the hardware, and it is recommended to observe under what circumstances the keyboard will fail after entering the system. 2.Try the notebook by pressing the blue fn+numlk.

It's fn or shift or ctrl, one of the numlk keys. Function keys of the notebook keyboard: FN+ESC, switch volume, FN+F1, lock the machine, FN+F2, select the system power scheme, FN+F3, hibernate, FN+F4, standby.

I haven't encountered a keypad that can still be locked.

The computer keypad is locked and unlocked:

1. Determine whether your computer is locked with numeric keys or if the alphanumeric keys and numeric keys are locked. 2. If only the number keys of the keyboard are locked: find "numlock" on your keyboard or"fn"+"nmlk1"key, if there is a separate "numlock", press it once to unlock it.

If it's a combination on the keyboard, press and hold at the same time"fn"+"nmlk1"button to unlock it. 3. If the entire keypad is locked, first find the keypad lock key position. It will usually be a lock icon.

If you don't have an icon, it's probably F11 or F12. Then press the FN + keyboard lock key to unlock it. If the keypad lock is F11, press Fn+F11 at the same time to unlock it.

To unlock some keypad locks, press FN + right alt + lock key).

The computer keypad is locked and unlocked as follows:

Situation 1: Sometimes it's just that the keys of the keyboard are locked, we can try to unlock it through FN+F8, this method works for the notebook. If the numeric keypad on the keyboard is locked, you can press the numlock key to unlock it, and see that there is a light on it to unlock.

Scenario 2: First, right-click the computer icon, and then click Manage. On the admin screen, click Device Manager on the left, then right-click on the keyboard and then click on Properties.

In the properties window we select the driver, then click Update Driver, and we will update the keyboard driver to troubleshoot this problem.

A computer keyboard that suddenly fails to type can be recovered in several ways:

1. FN+W is suitable for most models, Apple can press FN+Win.

You can try to press the shortcut key fn+w first, the shortcut key is suitable for most models, if you are using the Apple series, you can press the shortcut key fn+win to switch back, some win8 system models can try to press the shortcut key ctrl+fn + alt+w.

2. FN+NUMLOCK, if there is no NUMLOCK key, you can try to press FN+INSERT.

If the above key combination still doesn't work, you can try the fn+numlk key again, because sometimes it may be that we press too fast and press the switch numeric keypad without paying attention. Because some computers don't have "numlock.""button, at this time you need to press the fn+insert key.

3. The alt key may be stuck or malfunctioning, and you need to check the keys one by one.

If the keys don't work, we have to consider whether it is possible that the alt key is stuck, and under normal circumstances, when the alt is pressed, the computer keyboard will not be able to type. So we need to check the keys.

4. Reinstall the keyboard program.

After confirming that the keyboard is fine, but the keyboard still can't type, we have to consider whether it is a keyboard driver problem. We can find the "Device Manager" in Computer Management, then find the "Keyboard" option, click on it to view the keyboard driver, and try to reinstall.

Here's how to fix it:Operating Equipment: Dell laptops.

Operating system: win10

1. First, on the desktop, click on the "Text Document" icon.

2. Then in the notepad interface, the cursor is positioned to the position where you want to type the number.

The solution to unlock the computer keyboard is as follows:

1. Select "Start" and then "Run", then enter the OSK, after confirmation, bring up the on-screen keyboard that comes with the system, and then find the "Numlock" key, which is the abbreviated keyboard of "NLK" on the on-screen keyboard. Just tap this key with your mouse and the unlock will be successful.

It should be noted that if the "o" and "k" keys are locked, you will not be able to use the "osk" command, so you need to create a new text file on another laptop, named osk, and save it. After using the USB flash drive to copy it, copy the content of the OSK file name saved by the USB flash drive, paste it into the "Run" input box, and click the "OK" button.

2. The laptop keyboard is locked to restart the laptop, enter the "F2" key during the boot process of the laptop to check whether it can enter the BIOS security mode. If you can't enter BISO safe mode, this situation may be due to the laptop keyboard's data cable starting to loosen and need to be sent to a repair point for repair. If you can enter BISO safe mode, you can see what causes the keyboard to lock the system.

Then note press fn + scrlk or shift + scrlk (that is, fn or shift or ctrl, one of the keys + numlk keys. ) to try.
