When we encounter a situation where the keyboard does not respond, do not immediately think that the keyboard or the internal equipment of the notebook is damaged. Sometimes, the system is processing a large amount of data causing the system to be in a state of suspended animation, which can cause the keyboard to become unresponsive. At this point, we can try restarting the laptop, which may solve the problem.
If restarting does not solve the problem, we can check whether there is a problem with the driver. Right-click "My Computer," select "Manage," then find "Device Manager." Find the keyboard device here, expand the options, and see if there are any driver issues. If it is a driver problem, you can try uninstalling and reinstalling the driver.
If reinstalling the driver does not resolve the issue, it may be due to other installed software that conflicts with the keyboard driver. You can try pressing the F8 key to enter the advanced options and then select "Last Known Good Configuration" to restore the computer's configuration, which may help solve the problem.
Of course, the unresponsive keyboard may be due to a problem with the laptop hardware. If this is the case, we may need to send it in for repair. Usually, laptops have a warranty period. If there is a problem during the warranty period, you generally do not need to pay for repairs. However, if the warranty period has expired, a certain fee may be charged.
If the built-in keyboard cannot be used properly, we can consider using an external keyboard as an alternative. There are many external keyboards on the market that use USB interfaces. They are similar to the keyboards used on desktop computers (but the interface may be different), and are more convenient to use than the built-in keyboards of notebooks. If your built-in keyboard fails, it's a good opportunity to consider replacing it with an external keyboard.
Can’t you use the keyboard buttons without a keyboard? Of course not, we can also use the on-screen keyboard that comes with the Windows system. Click Start Menu, All Programs, Accessories, Accessibility, and then find On-Screen Keyboard. Of course, the on-screen keyboard has limited functions and is inconvenient to operate. The editor does not recommend its use. It is better to use an external keyboard. Note: If the built-in keyboard cannot be used, you might as well buy an external keyboard. It is not expensive and easy to operate.
Different operating systems have different methods of starting the on-screen keyboard. Choose the corresponding startup method according to your own operating system.
It may be that the keyboard is malfunctioning. You can try to clean the laptop keyboard and check whether each key pops up normally. If a key does not pop up, other keys may become unusable. If the laptop's built-in keyboard is damaged, you can choose to replace it, but the cost will be higher. Alternatively, you can also consider purchasing an external keyboard, which is more affordable.
If none of the above methods can solve your problem, try the following solutions:
1. Modify the laptop keyboard driver.
Open the system properties through "My Computer", select the Hardware tab, and open the Device Manager. We found that under the Chinese Windows XP operating system, the default keyboard driver is "Standard 101/102 keys or Microsoft natural PS/2 keyboard" . Right-click and select Update Driver, and the Hardware Update Wizard will appear: Select "Install from a list or specified location (Advanced)", click "Next", and select "Don't search. I want to choose the driver to install myself." Single Click "Next" and go to the "Select device drivers to install for this hardware" page and remove the small check mark in front of the "Show compatible hardware" checkbox. Select "Japanese PS/2 Keyboard (106/109 Key)" in the "Standard Keyboard Model" column, click "Next", and the "Update Driver Warning" will pop up, click "Yes". Continue to click "Yes" in the "Confirm Device Installation" window. Complete the Hardware Update Wizard and restart your computer.
2. Modify the registry.
Click the "Start" menu, click "Run", enter "regedit", open the registry, and enter "HKEY_LOCAL_MACHINE SYSTEMControlSet001ControlKeyboard Layouts". There are many subkeys in it. Through observation, I found that all those ending with "0804" Simplified Chinese input method. Open "E00E0804", you can see the "Layout File" sub-item in the sub-item on the right, double-click to open the item, change "kbdus.dll" in "Numeric Data" to "kbdjpn.dll", "OK" that is Can. By analogy, you can change the "Layout File" in all subkeys ending with "0804" to "kbdjpn.dll", depending on your commonly used input method. Then restart the computer and it's fine!
There are many reasons for notebook computer keyboard failure. The two most common ones are the two explained at the beginning. In addition, some computer viruses can also destroy computer keys.

At this time, we only need to restart the laptop to solve the problem. .
3. There is a problem with your keyboard driver. It is recommended to uninstall and reinstall it. If reinstalling the driver does not resolve the issue, it may be due to other installed software that conflicts with the keyboard driver. You can try pressing the F8 key to enter the advanced options and then select "Last Known Good Configuration" to restore the computer's configuration, which may help solve the problem.

5. If the built-in keyboard cannot be used, we can use an external keyboard and directly replace the built-in keyboard.
6. If you need the keyboard urgently, you can also use the on-screen keyboard that comes with the Windows system. Click Start Menu, All Programs, Accessories, Accessibility, and then find On-Screen Keyboard. Of course, the on-screen keyboard has limited functions and is inconvenient to operate. Basically, these are the only issues
