Lenovo IdeaPad Yoga C930-13IKB Glass Hardware Maintenance Manual

To enable the backlit keyboard, press the 'Fn' key and the spacebar simultaneously. This toggles the keyboard backlight through its different intensity levels.
First, check the power adapter and cable for any obvious signs of damage. Ensure that the power outlet is working. Try a different outlet or adapter if possible. If the problem persists, consider resetting the device by pressing the reset button near the charging port using a small pin.
To perform a factory reset, go to 'Settings' > 'Update & Security' > 'Recovery'. Under 'Reset this PC', click 'Get started' and choose whether to keep your files or remove everything. Follow the on-screen instructions to complete the reset.
Ensure that your hands are clean and dry. Restart the laptop to refresh the touchscreen driver. If the issue persists, update the touchscreen driver through 'Device Manager' by expanding 'Human Interface Devices', right-clicking 'HID-compliant touch screen', and selecting 'Update driver'.
Use the USB-C port on your Yoga C930 to connect to an external display. You may need a USB-C to HDMI or USB-C to DisplayPort adapter, depending on the input of your external display. Once connected, press 'Windows + P' to select a display mode.
Use a soft, lint-free microfiber cloth slightly dampened with water or a screen cleaner. Gently wipe the glass surface in a circular motion. Avoid using paper towels, abrasive materials, or strong solvents.
Reduce screen brightness, close unnecessary programs, and disable Bluetooth and Wi-Fi when not in use. Use the 'Battery Saver' mode found in 'Settings' > 'System' > 'Battery'. Also, consider updating the system and drivers to the latest versions.
Ensure that the laptop is on a flat, hard surface to allow proper ventilation. Check for dust accumulation in the vents and clean them with compressed air if necessary. Consider using a cooling pad and avoid running extensive programs concurrently.
Visit the Lenovo support website and download the latest BIOS update for your model. Follow the provided instructions carefully to install the update. Ensure your laptop is plugged into power throughout the process to prevent interruptions.
Unfortunately, the RAM on the Lenovo IdeaPad Yoga C930 is soldered onto the motherboard and cannot be upgraded. Consider optimizing software performance to make the most of available resources.
