To perform a factory reset, restart your laptop and press F10 during boot to access the VAIO Recovery Center. Follow the on-screen instructions to restore your system to factory settings. Ensure you back up important data beforehand.
First, try connecting the laptop to an external monitor to check for display issues. If the external monitor works, the issue may be with the laptop's screen or its connection. If not, consider updating the graphics drivers or checking the RAM.
To improve battery life, reduce screen brightness, disconnect unused peripherals, close unnecessary applications, and use power-saving modes. Additionally, calibrate your battery regularly for optimal performance.
Turn off the laptop and disconnect it from power. Use a can of compressed air to remove debris between keys. For more thorough cleaning, gently wipe the keys with a damp microfiber cloth. Avoid excessive moisture to prevent damage.
To upgrade RAM, turn off the laptop and remove the battery. Access the RAM compartment on the underside of the laptop. Replace the existing modules with compatible ones, ensuring they are securely seated. Reassemble and power on the laptop.
A slow system can be due to software bloat, insufficient RAM, or a fragmented hard drive. Uninstall unnecessary programs, increase RAM if possible, and run disk cleanup and defragmentation tools to improve performance.
Ensure Wi-Fi is turned on by using the switch or function keys. Click the network icon in the taskbar, select the desired Wi-Fi network, and enter the password if prompted. If issues persist, check the wireless adapter settings.
First, check if the touchpad is disabled via function keys. If not, update or reinstall the touchpad drivers from the Device Manager. If the issue continues, consider checking hardware connections internally.
Visit Sony's official support website, download the latest BIOS update for the VGN-FZ240E, and follow the provided instructions. Ensure the laptop is connected to a reliable power source during the update process.
