Ensure the laptop is charged. Try a hard reset by holding the power button for 10 seconds. If it still won't turn on, try removing any connected peripherals and try again. If the issue persists, contact Samsung support.
To improve battery life, reduce screen brightness, close unused applications, use battery saver mode, and avoid running intensive programs when on battery power.

Click the network icon in the taskbar, select the desired wireless network, enter the password if required, and click 'Connect'.
Use a soft, lint-free cloth slightly dampened with water or an appropriate screen cleaner. Gently wipe the screen and keyboard. Avoid using excessive liquid or spraying directly onto the laptop.
You can extend the storage by using an external hard drive, USB flash drive, or cloud storage solutions. Unfortunately, internal storage upgrades are not typically feasible for this model.

To enable or disable the touchpad, go to 'Control Panel' > 'Hardware and Sound' > 'Mouse' > 'Device Settings' tab, and then select 'Enable' or 'Disable' the touchpad.
