To improve performance, ensure your operating system and drivers are up to date. Consider upgrading the RAM if possible, and regularly clean your system to remove unnecessary files. Adjust power settings for maximum performance when needed.
Check the touchpad settings in the control panel or settings menu to ensure it's enabled. Update the touchpad driver through the Device Manager. If the issue persists, perform a system restart.
Click on the network icon in the taskbar, select your Wi-Fi network from the list, and click 'Connect'. Enter the network password if prompted. Ensure Wi-Fi is turned on through the function key (usually Fn + a function key with a Wi-Fi icon).
Update the graphics driver via Device Manager or Samsung's support website. Check the display settings to ensure the refresh rate is set correctly. If the problem persists, it may be hardware-related, requiring professional repair.
