Laptops offer incredible portability, but when primarily used at home with an external monitor, the laptop screen becomes redundant. Running your laptop in clamshell mode (closed lid) offers numerous benefits, including a larger display, improved ergonomics, and reduced power consumption. This guide details how to properly set up your laptop for clamshell mode, the advantages it provides, and best practices for optimal performance.

Finally, a laptop stand or holder is highly recommended. This keeps your workspace organized, elevates the laptop for better airflow, and helps manage heat.
Configuring Windows for Clamshell Mode
Preventing your laptop from sleeping when the lid is closed requires a simple adjustment in Windows settings.
Open the Start menu, search for “Control Panel,” and launch it. Navigate to “Hardware and Sound” -> “Power Options.” On the left sidebar, click “Choose what closing the lid does.”

Under “When I close the lid,” change both “On battery” and “Plugged in” settings to “Do nothing” and click “Save changes.” Your laptop will now remain active when closed, enabling seamless use with an external monitor.
Best Practices and Considerations
While clamshell mode is generally straightforward, a few points warrant attention.

Keeping your laptop plugged in is advisable to avoid battery drain, especially during extended use with an external monitor.
Some high-performance gaming laptops, like the Razer Blade 16, expel air from the top. Closing the lid may obstruct airflow, leading to increased heat, especially during intensive gaming sessions. If your laptop vents from the bottom, sides, or back, this is less of a concern.

A laptop stand or cooling pad is crucial for maintaining optimal airflow and preventing overheating, particularly during demanding tasks. It also helps declutter your workspace.
