Users on Lenovo laptops often struggle to type the @ and # symbols due to regional keyboard layout mismatches or driver conflicts. The most common fix involves verifying that your Windows input language matches your physical keyboard's layout, typically switching between US International and UK English settings in the Language bar.
Understanding Keyboard Layout Mismatches
The primary reason you cannot type specific symbols like the at sign (@) or hash (#) is a discrepancy between the software configuration of your operating system and the physical hardware of your laptop. Lenovo laptops are manufactured globally and may ship with different regional layouts depending on where they were sold. If your computer thinks it has a United Kingdom keyboard but you are using a United States model, the key combinations for these symbols will be inverted or mapped incorrectly. In many standard US layouts, the @ symbol is accessed by holding Shift and pressing the 2 key, while the # symbol requires Shift and the 3 key. However, on UK layouts, the @ symbol is often located next to the Enter key or requires Alt Gr combinations, and the # symbol might be found near the backslash or quotation mark keys. This confusion is not a hardware failure but rather a software interpretation error. You must ensure that the active input method in Windows corresponds exactly to the physical keyboard you are using.

To resolve this issue, you need to check and adjust your language settings within Windows. Start by looking at the taskbar in the bottom right corner of your screen. You will see an abbreviation such as ENG, USA, or GBR. Right-click on this indicator and select Language settings or Text services and input languages. From here, you can view the list of installed keyboards. If you see multiple entries like "United States (International)" and "United Kingdom," one of them is likely active when it should not be. Click on the language you want to use and select Options to verify the default keyboard layout. If you are unsure which layout your physical keyboard uses, try selecting "United States" first. Test the @ and # keys immediately after making the change. If the symbols appear correctly, you have identified the problem. If not, switch to the other available layout and test again. It is crucial to remove any unnecessary language packs that are not relevant to your region to prevent accidental switches during typing sessions.Checking for Sticky Keys or Filter Keys Interference
Sometimes the issue is not the layout itself but an accessibility feature interfering with key presses. Windows includes features like Sticky Keys and Filter Keys that modify how modifier keys like Shift behave. If Filter Keys is enabled, the system ignores brief or repeated keystrokes, which can cause symbols to drop or fail to register entirely. Navigate to Settings and then Accessibility. Look for the Keyboard section and ensure that both Sticky Keys and Filter Keys are turned off. Additionally, check the Ease of Access center if you are on an older version of Windows. These features are designed to help users with motor impairments but frequently cause frustration for general users who accidentally toggle them via shortcut keys. Disabling these options ensures that every key press is registered instantly and accurately by the operating system.Updating and Reinstalling Keyboard Drivers
If changing the language layout does not solve the problem, the underlying driver for your keyboard may be corrupted or outdated. Lenovo provides specific utility tools to manage these drivers efficiently. Open the Lenovo Vantage application, which comes pre-installed on most modern Lenovo devices. Navigate to the Hardware Settings or Device Configuration section. Here, you can check for firmware updates related to the keyboard or input devices. Alternatively, you can manually update the driver through Device Manager. Right-click the Start button and select Device Manager. Expand the Keyboards section, right-click your listed keyboard device, and choose Update driver. Select Search automatically for updated driver software. If this fails, consider uninstalling the device and restarting your laptop. Windows will automatically reinstall the default generic driver upon reboot, which often clears out any persistent configuration errors that prevent symbol entry.Testing with On-Screen Keyboard
As a diagnostic step, you can use the On-Screen Keyboard to determine if the issue is hardware-related. Press Win + Ctrl + O to launch the virtual keyboard. Try clicking the @ and # keys on the screen. If these symbols appear correctly in a text editor, your hardware is functional, and the issue remains strictly software or configuration-based. If the on-screen keyboard also fails to produce the correct symbols, the problem lies deeper within the Windows registry or system files, potentially requiring a repair install of Windows.

Why do my symbols work on one program but not another?
This usually indicates that the specific application has its own custom keyboard shortcuts or language settings that override the global Windows configuration. Check the preferences or settings menu within that application to ensure no conflicting hotkeys are assigned to the @ or # keys.
Can I permanently lock my keyboard to US layout?
Yes, you can remove all other language packs from your system. Go to Settings > Time & Language > Language, select any non-essential languages, and click Remove. This prevents the system from switching layouts unexpectedly if you press the Windows key plus Spacebar.
What if my laptop has a UK keyboard but I prefer US symbols?
You should keep the input language set to United Kingdom to match the physical keys, but you can customize the key mappings using third-party software like Microsoft PowerToys. This allows you to remap specific keys to behave differently without changing the entire layout.
Does resetting the BIOS fix keyboard symbol issues?
Resetting the BIOS rarely fixes symbol typing issues because these are handled by the operating system, not the firmware. However, if your keyboard is completely unresponsive, loading default BIOS settings can resolve low-level hardware detection errors.
How do I know if my keyboard is physically broken?
If the keys produce no output at all, even when using the On-Screen Keyboard, or if specific rows of keys fail consistently across all programs, the hardware may be damaged. In such cases, testing with an external USB keyboard helps isolate whether the internal ribbon cable or matrix circuit has failed.
