To improve battery life, adjust your power settings to 'Power Saver', reduce screen brightness, and disable unnecessary background applications. Regularly updating your drivers can also help.
To clean your laptop, power it down and unplug all cables. Use a soft, lint-free cloth slightly dampened with water to wipe the surfaces. Use compressed air to remove dust from the keyboard and vents.
To update drivers, visit the Dell Support website, enter your laptop's service tag, and download the latest drivers. You can also use the Dell Update utility for automatic updates.

Ensure that the vents are not blocked and that the fan is working. Use your laptop on hard surfaces and consider using a cooling pad. Clean the vents regularly to remove dust build-up.
Connect the external monitor to your laptop using an HDMI or VGA cable. Press the 'Fn' key along with 'F8' to toggle between display modes. Adjust display settings in the Control Panel if necessary.
