How to Keep Your Computer Awake

Most modern operating systems put your device to sleep automatically to save energy. While useful in general, this can interrupt downloads, video playback, presentations, or remote work. To prevent your computer from going into sleep mode, you can use browser-based tools like MoreCoffeePlease — a simple web app that keeps your screen active without installing anything.

What is the Wake Lock API and Why Do I Need It?

The Wake Lock API is a modern browser feature that allows websites to request the screen to stay on. This is essential when you're doing tasks that require your device to remain awake. Whether you're watching a livestream, monitoring code execution, or just reading, Wake Lock ensures your device doesn't go to sleep unexpectedly.

When is Wake Lock Useful?

Downloading large files that take time
Running presentations or webinars
Reading long articles or documentation
Keeping dashboards or data visualizations visible
Watching videos or livestreams without interruptions

What Makes MoreCoffeePlease Different?

MoreCoffeePlease is a lightweight, privacy-friendly tool that runs entirely in your browser. We use the Wake Lock API when supported, and fall back to a silent background video when it's not — ensuring compatibility across all modern devices and browsers. We don’t collect data, use cookies, or require installation. Just open the site, click start, and stay focused.

Designed for developers, students, creators, and anyone who needs uninterrupted time at their computer — MoreCoffeePlease helps you take control of your screen time, effortlessly.

Manual Options to Prevent Sleep on PC and Mac

While MoreCoffeePlease keeps your screen awake automatically, you might want to explore additional manual settings to prevent your computer from sleeping — especially if you’re using strict power-saving configurations or running long tasks.

For Windows 10 and 11

Adjust sleep settings: Go to Settings → System → Power & sleep, and set "Sleep" to Never for both battery and plugged-in modes.
Use high performance mode: In Control Panel → Power Options, choose or create a plan that keeps your PC active longer.

For macOS (MacBook and iMac)

Change energy settings: Go to System Settings (or System Preferences) → Battery → Power Adapter, and set "Turn display off after..." to Never. Also check "Prevent your Mac from sleeping automatically."
Advanced option — use Terminal: Open the Terminal app and type caffeinate to keep your Mac awake while the terminal is running. Press Control + C to stop it.

These built-in methods can complement the browser-based solution that MoreCoffeePlease offers, giving you full control over your computer’s behavior.
