Tastatur Schreibt Nur Noch Gross

Willkommen! You've arrived in Germany (or Austria, Switzerland, or perhaps you're just using a German keyboard) and suddenly, *everything* you type is in ALL CAPS! Don't panic! This is a very common problem, and usually a very simple fix. This guide will walk you through the most likely causes and how to get your keyboard behaving normally again. Think of it as your quick guide to keyboard sanity in the German-speaking world.

The Caps Lock Culprit: The Most Likely Suspect

Let's get the obvious one out of the way first. The most frequent reason why your German keyboard is stuck in uppercase is the Caps Lock key. Unlike some modern keyboards that have an on-screen indicator or subtle light, many German keyboards, especially on older laptops or external keyboards, don't give you any visual cue that Caps Lock is active. This can be particularly confusing if you're used to a keyboard that does.

How to fix it: Simply press the Caps Lock key once. Seriously, that's usually it. The Caps Lock key is a toggle, meaning it switches between uppercase and lowercase with each press. On a German keyboard, it's generally located on the left side of the keyboard, above the Shift key. Look for a key with a small padlock symbol and the words "Caps Lock" (sometimes abbreviated to "Caps").

If you're *absolutely* certain you haven't accidentally hit the Caps Lock key, move on to the next possibility.

The Shift Key Saga: A Sticky Situation

Another potential cause is a stuck Shift key. The Shift key, when held down, converts lowercase letters to uppercase. If the key is physically stuck down, or if the operating system is somehow interpreting it as constantly pressed, you'll get the same "stuck in caps lock" effect.

How to check and fix:

Visually inspect the keys: Look closely at both your left and right Shift keys. Are either of them physically depressed more than the other keys? Is there any visible debris stuck under them?
Try pressing the Shift keys repeatedly: Press both the left and right Shift keys several times, firmly but gently. This might dislodge any small particles or debris that are causing them to stick.
Use a keyboard cleaner: If you suspect debris is the problem, use a can of compressed air to carefully blow out any dust or crumbs from under the Shift keys.
Test the Shift keys individually: Open a text editor (like Notepad or TextEdit) and try holding down only the left Shift key and typing some letters. Then repeat the process with only the right Shift key. If one of the Shift keys is consistently causing problems, that's likely your culprit.
Restart your computer: Sometimes, a temporary software glitch can cause the Shift key to behave erratically. A simple restart can often resolve this.

Language Settings: A German Keyboard Pretender?

This is less common, but still worth checking, especially if you've recently changed your operating system or installed new software. Sometimes, the input language settings on your computer can get confused, leading to unexpected keyboard behavior. While it usually wouldn't cause *only* uppercase typing, it could interact with other settings to create this issue.

How to check and fix (Windows):

Go to the Windows Start menu and search for "Language settings."
In the Language settings, look for the "Preferred languages" section.
Make sure "Deutsch (Deutschland)" or the appropriate German dialect is listed. If it's not, add it by clicking "Add a language."
Once German is added, make sure it's at the top of the list. You can drag languages to reorder them.
Click on the German language and then click "Options."
Under "Keyboards," make sure the correct German keyboard layout is selected (e.g., "German (Germany) - QWERTZ"). If not, add the correct layout.

How to check and fix (macOS):

Open System Preferences (usually found in the Apple menu).
Click on "Keyboard."
Go to the "Input Sources" tab.
Make sure "German" or your preferred German dialect is listed. If not, click the "+" button to add it.
Verify that the correct keyboard layout (e.g., "German") is selected.
If you have multiple input sources, make sure you haven't accidentally switched to a different one (look for a flag icon in the menu bar).

Accessibility Features: Sticky Keys and Filter Keys

Operating systems often include accessibility features designed to assist users with physical disabilities. Two features, Sticky Keys and Filter Keys, can sometimes inadvertently cause keyboard problems. Sticky Keys allows you to press modifier keys (like Shift, Ctrl, or Alt) one at a time instead of holding them down. Filter Keys ignores brief or repeated keystrokes, which can affect typing behavior.

How to check and disable (Windows):

Go to the Windows Start menu and search for "Ease of Access keyboard settings."
Make sure that both "Sticky Keys" and "Filter Keys" are turned off.

How to check and disable (macOS):

Open System Preferences.
Click on "Accessibility."
Select "Keyboard" in the left sidebar.
Make sure "Sticky Keys" is unchecked.
Also, check "Slow Keys" under "Hardware" and ensure it is unchecked. Slow keys is similar to filter keys on Windows.

The Num Lock Nuisance (Less Likely, But Possible)

While highly unlikely to cause *only* uppercase typing, an accidentally activated Num Lock key could be interfering with other keyboard functions, potentially leading to unpredictable behavior. The Num Lock key toggles the numeric keypad on the right side of the keyboard between number input and cursor control.

How to fix it: Press the Num Lock key to toggle it off. The key is usually labeled "Num Lock" or "Num Lk" and is located on the numeric keypad. Some keyboards have a small indicator light to show when Num Lock is active.

Hardware Problems: A More Serious Diagnosis

If you've tried all the software-based solutions and your keyboard is still only typing in uppercase, the problem might be a hardware issue. This could be a faulty keyboard controller, a short circuit, or damage to the keyboard itself.

What to do:

Try a different keyboard: If possible, connect a different keyboard to your computer to see if the problem persists. If the new keyboard works correctly, the issue is definitely with your original keyboard.
Test the keyboard on a different computer: If you have access to another computer, try plugging your problematic keyboard into it. This will help determine if the issue is with the keyboard itself or with your computer's hardware or software.
Contact a repair technician: If you suspect a hardware problem and you're not comfortable disassembling the keyboard yourself, it's best to take it to a qualified computer repair technician.

A Final Word of Encouragement

Dealing with a keyboard that's stuck in uppercase can be incredibly frustrating, especially when you're trying to communicate in a foreign language. But remember, most of the time, the solution is simple! Start with the Caps Lock key, then move on to checking the Shift keys and language settings. With a little troubleshooting, you'll be back to typing normally in no time. Viel Glück! (Good luck!)
