How to deal with keyboard consecutive input failure
When using a computer, if it's a keyboard problem when keys on the keyboard are not entered consecutively, is it a keyboard problem? Is it a Windows problem? Let's organize how to solve the part that makes you think step by step.
Sometimes when I use a computer, there are times when the key is not entered consecutively.
For example, when you write like hhhhhhh, you just have to press the h key once, but you have to hit it many times to bother you,
Or I wanted to move the cursor to the left or right, so I thought it would go if I pressed the arrow key, but it stopped...
Is it a keyboard problem at first? Is it a window problem? I think about a lot of things
I would like to calmly organize what to do in this case.
1. Example of symptoms
- Only one character is entered even if the key is pressed continuously
- Intermediate break even when typing fast
- Ctrl, Shift, Alt combination not working
- Key entry delayed or unresponsive
2. Key causes and workarounds
✅[1] Accessibility function – turn off 'filter key'
The 'filter key' function of the window can limit continuous input.
The 'filter key' function of the window can limit continuous input.
✔ How to check
✅[3] Try connecting to another USB port (if it is a wired keyboard)
There may be something wrong with the port itself.
Connect to another port or another PC to see if it's a keyboard problem itself.
✅ [4] Bluetooth Keyboard connection unstable (if wireless)
Bluetooth keyboards can cause input delays due to low battery, disconnection, etc.
Try replacing the battery and reconnecting Bluetooth.
✅[5] Key entry restrictions for specific programs
Some security programs or game/work apps also restrict keyboard input.
If you have an app that you recently installed, please stop working and double-check it.
✔ Test Key Input in BIOS
- Open Windows Key + I → Settings
- Accessibility > Keyboard
- Switch to Disable Filter Key
💡 The 'filter key' is originally intended for users with hand discomfort, but it may seem like a malfunction to ordinary users.
✅[2] Check keyboard driver error
✔ Measures to be taken
- Open Device Manager (Win + X → Device Manager)
- Keyboard > Standard PS/2 Keyboard Right-click
- Automatically reinstalled when rebooted after device removal
✅[3] Try connecting to another USB port (if it is a wired keyboard)
There may be something wrong with the port itself.
Connect to another port or another PC to see if it's a keyboard problem itself.
✅ [4] Bluetooth Keyboard connection unstable (if wireless)

3. Check keyboard hardware self fault
You can check the hardware status of your keyboard in the following two ways:✔ Use keyboard test site
- https://keyboardtester.com/
- Press all keys to see the response → If there is no response, there is a high possibility of hardware problems
✔ Test Key Input in BIOS
- Enter BIOS by pressing F2 or DEL key when booting PC
- Check if the key is pressed in the BIOS screen → If it is not pressed, there is a possibility of device failure ↑
Bonus tip: How to reset your keyboard
Initialize Windows default keyboard settings
- Control Panel > Time and Language > Language → Choose Your Language > Options > Remove Keyboard and Add Again
