Click the network icon in the taskbar and select your desired Wi-Fi network from the list. Enter the network password if prompted and click "Connect." Ensure Wi-Fi is enabled on your device.
If the touch screen is unresponsive, try restarting your computer. Ensure your system drivers are up to date, and consider recalibrating the touch screen via the Control Panel under "Tablet PC Settings."
Turn off the computer and unplug all cables. Remove the back cover and locate the hard drive. Unscrew and disconnect the existing hard drive, then replace it with the new one. Reassemble the computer and reinstall the operating system if necessary.
To clean the screen, turn off the computer and unplug it. Use a soft, lint-free cloth lightly dampened with water or a screen cleaner. Gently wipe the screen in circular motions, avoiding excessive pressure.
Overheating may be caused by dust buildup or inadequate ventilation. Regularly clean the vents and fans with compressed air, and ensure the computer is used on a hard, flat surface. Consider using a cooling pad to improve airflow.
Visit the Lenovo support website and download the latest BIOS update for your C340 model. Follow the provided instructions carefully to update the BIOS, ensuring the computer remains powered on during the process.
