- Press the Windows key and type “Device Manager” in the search bar.
- Open the Device Manager and expand the Keyboards section.

Step 2: Cleaning Your Dell Inspiron 7559 Keyboard
Over time, dust, debris, and dirt can accumulate under the keys of your Dell Inspiron 7559 keyboard, causing unresponsiveness or sticky keys. Cleaning your keyboard can often restore its functionality.
1. Turn Off the Laptop
Always power off your laptop before cleaning to avoid any potential damage or accidental key presses.
2. Use Compressed Air
Use a can of compressed air to blow away any dirt or debris trapped under the keys. Hold the can at an angle and blow air between the keys to dislodge any particles. Be gentle to avoid damaging the keyboard.
3. Clean the Keyboard Surface
To clean the surface of the keyboard, use a soft microfiber cloth lightly dampened with water or a mild cleaning solution. Avoid using harsh chemicals or abrasive materials that could scratch or damage the keyboard.
4. Use Isopropyl Alcohol for Sticky Keys
If specific keys are sticking, use a cotton swab lightly dipped in isopropyl alcohol to clean around the base of the keys. The alcohol helps to dissolve any sticky residue without damaging the components.
Step 3: Resetting Keyboard Settings
If your keyboard issues are software-related, resetting your keyboard settings might resolve the problem. To reset your keyboard settings on your Dell Inspiron 7559, follow these steps:
- Press the Windows key and type “Control Panel” in the search bar.

Once the keyboard settings are reset, restart your laptop and check if the problem is fixed.
Step 4: Advanced Solutions for Hardware Issues
If the basic troubleshooting steps don’t solve your keyboard problems, there may be a hardware issue. Below are some advanced solutions you can try:
1. Check the Keyboard Connection
If you’re comfortable working with hardware, you can check the physical connection of the keyboard to the laptop’s motherboard. For this, you’ll need to:
