Lenovo IdeaPad S340-15IWL Troubleshooting

The device’s camera will not function.

Some devices have a protective slide in front of their built-in camera for security reasons, or may have a seal or sticker placed over the lens to prevent potential damage. If the device’s camera does seem to power on but the picture quality is black or blurry, there could be something in front of the lens.

The F8 key on the top row of the device’s keyboard will either enable or disable the camera. Pressing the F8 key will display a camera graphic on the screen. If the graphic has a dash through the camera, the camera is disabled. Pressing the F8 key again will enable the dash, enabling the camera.

Using the search bar in the lower-left corner of the screen, search for “Camera Privacy Settings” and hit the Enter key. In the Camera Privacy Settings menu, make sure that the “Allow Apps to Access Your Camera” option is switched to On.

Right-click on the search bar in the lower-left corner of the screen, and select “Device Manager” from the resulting menu. Once the application is open, double-click the “Cameras” menu to expand it. Double-click on the “Integrated Camera” listing, and then select the “Drivers” tab. Click “Uninstall Device” in the lower-left corner of the window, and then restart the device. As the device restarts, Windows will re-download and reinstall the drivers required for the camera.

If none of the above options work, an internal component in the camera itself may be damaged. In this case, you will most likely have to replace the camera altogether. Click here for a detailed guide on how to replace the device’s camera.

The device will not charge or stay on after being unplugged.

Locate the search taskbar and find either energy saver or brightness settings. Adjust energy saver settings in favor of lowering energy usage, or adjust the brightness levels to a lower setting to conserve battery life.

If you have access to another device that uses the same charger as your current one, attempt to charge that device with your current charger. If that device charges without issue, then your device’s charging port may be damaged, unclean, or dusty. Using a cotton swab, gently clean the inside of the device’s charging port in order to remove dust and debris.

If you have access to another charger capable of powering your device, attempt to charge your device with it. If that charger functions normally, there is likely an issue with your current charger. Note that replacing chargers can be expensive. Do not purchase a new charger for your device unless you are absolutely certain that your current charger is no longer functioning.

If none of the above options work, an internal component in the device’s battery may be damaged. In this case, you will most likely have to replace the battery altogether. Click here for a detailed guide on how to replace the device’s battery.

The device’s screen has suffered cosmetic damage or will no longer display text and images properly.

If the battery is dead, the screen will not turn on. Try plugging the charger into the computer, once connected press the power button located in the upper right-hand corner. The screen should turn on as soon as the computer is plugged in, but if not allow it to charge for a few minutes, then try again.

If the computer is on, but the screen is still black try restarting the computer. Unplug any devices that may be connected to the computer, such as USB drives, mice, or printers. Then hold down the power button, located in the upper right-hand corner, for 3 to 5 seconds. Let the computer sit for a few minutes, then try to turn it back on.

In order to reset the display mode press the following keys on the keyboard: Windows Key + Ctrl + Shift + B. Press all of these keys at once and then release them immediately. Once you release the keys, you should hear a beeping noise come from your device and the screen should go black for a few seconds. The screen should then turn back on after the display mode refreshes.

Shut down the computer completely, refer to the steps in Option 2, and then remove the battery (refer to “Device won’t charge” for steps). Leave the battery out for 30 seconds. Hold down the power button for 60 seconds and then put the battery back in, refer to “Device won’t charge - option 2.” Then connect the computer to the charging cord and turn the computer back on.

This fix is a nuclear option as it will remove all of your data, so try all other options first. A factory reset sets your device back to the way it was when it came out of the box, so make sure that you back up all of your important data on an external hard drive (a portable device that plugs into your computer).

If none of the above options work, an internal component in the camera itself may be damaged. In this case, you will most likely have to replace the screen altogether. Click here for a detailed guide on how to replace the device’s screen.

The device’s keyboard will not input any characters.

If only some keys on the keyboard are not working, there may be a piece of debris obstructing them. Power off the device and turn it upside down, which can dislodge small objects stuck within the keyboard.

Various keyboard modes like Sticky Keys and Toggle Keys can be turned on by mistake and impair the device’s ability to type. To make sure all of these keyboard modes are disabled, follow these steps:

1. Click on the Speech Bubble icon on the bottom right corner of the screen.
2. A menu will appear on the right side of the screen. Select the “Settings” option in the top right corner. (Note: the “Settings” option may also be in a group of tiles at the bottom of the menu.)
3. On the Settings home screen, select “Ease of Access Settings.”
4. Using the menu on the left side of the screen, scroll down to the “Interaction” header and select the “Keyboard” option.
5. If any of the options in the Keyboard Menu are turned on, turn them off.

Windows has built-in troubleshooting applications for several hardware and software issues. Navigate to the settings menu, and select the Update & Security option. Select “Troubleshoot” from the menu on the left side of the screen, and check for suggestions under the “Recommended Troubleshooting” heading. If no options are listed, select the “Additional Troubleshooters” link at the bottom of the menu and choose the “Keyboard” option. Run the troubleshooter, and Windows will attempt to diagnose and repair any keyboard issues on its own.

Right-click on the search bar in the lower-left corner of the screen, and select “Device Manager” from the resulting menu. Once the application is open, double-click the “Keyboards” menu to expand it. Right-click on all of the listings in the menu and click on “Uninstall Device”. Restart the device. As the device restarts, Windows will re-download and reinstall the drivers required for the keyboard.

If none of the above options work, an internal component in the keyboard itself may be damaged. In this case, you will most likely have to replace the keyboard completely. Click here for a detailed guide on how to replace the device’s keyboard.

The device is hot to the touch or is displaying messages saying it has overheated.

Power down the device and allow time for it to cool off. When the fan stops spinning and the device is physically cooler, reboot and resume activities.

Running graphically intense or complex programs can put a strain on the device’s hardware. If overheating only occurs while running certain programs, lower their graphics settings or switch them to a preset “performance mode.”

If the device’s fan makes more noise than usual or doesn’t spin at all when overheating, it could be in need of repair or replacement.

If none of the above options work, an internal component in the fan itself may be damaged. In this case, you will most likely have to replace the device’s fan and/or cooling system. Click here for a detailed guide on how to replace the device’s fan.
