To perform a factory reset, restart the laptop and press F4 when the Samsung logo appears. This will launch the Samsung Recovery Solution. Follow the on-screen instructions to perform a factory reset. Ensure you back up important data before proceeding.
Ensure that the laptop is on a hard, flat surface to allow adequate ventilation. Clean the air vents with compressed air to remove dust. If the problem persists, consider using a cooling pad or consult a professional technician.
Visit the Samsung support website and navigate to the drivers section for the ATIV Book 8 model. Download and install the latest drivers for your specific operating system. Alternatively, use Samsung Update software to automatically check for updates.
Check the power adapter and battery connections. Try a different power outlet. If the battery is removable, reseat it. If the issue persists, perform a power reset by holding the power button for 15 seconds. If none of these steps work, seek professional repair services.
Reduce screen brightness, disable unnecessary startup programs, and use the battery saver mode. Additionally, close unused applications and consider replacing the battery if it's old and not holding a charge well.
Use a microfiber cloth slightly dampened with water or a screen-cleaning solution. Gently wipe the screen in circular motions, avoiding excessive pressure. Do not spray liquid directly on the screen.
Use an HDMI cable to connect the laptop to the TV or monitor. Press the F4 key to switch the display mode between the laptop screen, the external display, or both. Ensure the TV or monitor is set to the correct HDMI input.
Ensure that the touchpad is not disabled by pressing the function key that controls the touchpad (usually Fn + F6). Update the touchpad driver from Samsung's support website. If the problem persists, check for hardware issues with a technician.
Click on the network icon in the system tray, select your wireless network, and click 'Connect'. Enter the network password if prompted. Ensure that the wireless adapter is enabled and working properly.
Power off the laptop and disconnect all peripherals. Remove the screws on the back panel to access the RAM slots. Carefully insert the new RAM module into an available slot or replace the existing one. Reassemble the laptop and power it on to ensure the RAM is recognized.
