It would be a disaster if you were working on a laptop where any one key was paralyzed, or the entire keyboard stopped working. Use the following methods so you can quickly get back to work!
Check whether the problem is with the hardware or software
Before you start repairing, you need to know that the error is caused by the keyboard hardware itself, or a software malfunction that prevents Windows from receiving key signals. Learning this will save you a lot of time in future repairs.
First try to save the projects and work you are doing with the mouse if you can not use the keyboard. For example, in Word, click File >> Save or Save As .
Next, restart the computer and try to access the BIOS. Each laptop line will have a unique shortcut to do this, you learn the article How to enter the BIOS on your computer or laptop .
- If you can enter the BIOS with the keyboard shortcuts, and you can control the keyboard normally in the BIOS. That means your problem lies with the software, or specifically the Windows operating system.
- If you are unable to access the BIOS with the keyboard, chances are the error is from the keyboard itself and you will most likely have to have a repair or replacement repaired by a technician.
Reboot the PC
This is an "unexpectedly effective" way to fix many errors on Windows computers. Try using the mouse to restart the computer to see if the keyboard is working properly. If this doesn't work and you're stuck at the login screen, use the Virtual keyboard to log back in: at the login screen, pay attention to the lower right corner, select Ease of access >> On-screen Keyboard .
Reinstall the driver for the keyboard
Sometimes the keyboard driver can be problematic, especially if you are the one who regularly installs 3rd party software or improperly shuts down your computer.
Step 1: Open the virtual keyboard on Windows. In the search box, enter Device Manager and then proceed to open this application.
If you see any lines with yellow exclamation points, this is most likely a problem. However, even if you do not see an exclamation point, you should follow the steps below to reinstall the keyboard driver.
Step 2: Right-click the keyboard driver and select Update driver, and then restart the computer.
Step 3: If Update has not worked, select Uninstall device and then restart. Windows will automatically grab your common drivers keys, which gives the keyboard a chance to work again.
Not only that, but sometimes the related drivers such as chipsets, USB errors also make the keyboard not work. Please refer to the Top 5 automatic software Update Driver to be able to upgrade the driver comprehensively.
Change keyboard layout
If your keys are still active but when pressed again creates letters that are different from the key, the layout of the language or keyboard may have changed (or someone willfully prank you).
Enter Language settings in the search box and open this setting.
Click the current language you are installing on Windows, and then select Options .
Check in Keyboards section if the keyboard type is QWERTY or not. If it is not correct, click Add a keyboard and select the QWERTY keyboard that is equivalent to the language you use .
Then remove the wrong keyboard layout with the Remove button .
Adjust keyboard settings
Some keyboard settings can cause abnormal key presses. For example, setting a key repetition delay that is too short may cause keystrokes to enter two or more characters.
Go to your keyboard settings by opening Control Panel >> enter Keyboard and the search box in the top right corner >> Open Keyboard .
Adjust the parameters accordingly:
- Repeat delay: The key repeat delay
- Repeat rate: Time between key iterations
- Cursor blink rate: Speed blinking cursor
When you're done, click Apply to apply.
Due to the virus
If you have tried the above methods and the keyboard still does not work properly, it is likely that it has become a victim of Virus. Run a virus and malware scan using one of the free antivirus software.
Dust test
The above solutions all solve software-based problems. But what if you did a test and suspected the problem was from hardware? You should start cleaning the keyboard immediately.
Turn your laptop upside down, or at least an angle of 45 to 75 degrees from the horizontal, then shake it gently to allow dirt to fall. Sometimes things like breadcrumbs can get stuck under the keys.
If you have a keyboard vacuum or a compact box, clean the nooks and crannies on your keyboard. If a large area on the keyboard is damaged by spilled liquids such as soft drinks, coffee, it is best to replace the keyboard.
Remove the battery (if possible).
Sometimes, the battery of a laptop under the keyboard can cause problems. If your laptop uses removable batteries, try shutting down, removing the battery, and then plugging in the power cord again. Now start the computer without installing the battery.
If the keyboard only works when you remove the battery, you may need to replace it (make sure you can get an original battery).
Fix the connection to the mainboard
Sometimes, a laptop keyboard is disconnected from the motherboard, making the keyboard usage flicker or completely unusable. If you're a pro, try removing the case and fixing the connection between the keyboard and the motherboard to make sure.
If not, consult the manufacturer's website, instructions on how to disassemble the laptop, and reconnect the cables. Or, for added security, take it to a professional service for inspection.
Take the warranty
The above methods only apply in case you are in urgent need of a laptop to handle the work promptly. Tips Make still recommends that you seek the help of experts. If the laptop is still under warranty, you can get the keyboard replaced quickly. Otherwise, letting a professional repair it is still the safest way.
Note that before sending your laptop for warranty service, back up your hard drive and important data.
