Explore the world of hardware, from cutting-edge devices and components to the systems that power our digital lives. Whether it's server hardware, networking gear, or the latest gadgets, this tag covers the innovations and tools that make modern computing possible. Learn how hardware impacts performance, scalability, and reliability in tech, and discover tips for optimizing your infrastructure.
This guide explains how to diagnose and resolve suspend/resume failures on modern laptops. Learn common hardware, firmware, and driver pitfalls, recognize early warning signs, and apply systematic testing to achieve reliable low-power operation.
Systemd orchestrates Linux suspend and resume. From systemd-logind deciding when to sleep, to inhibitors blocking it, to pre/post scripts and sleep.conf tuning defaults, learn how systemd coordinates kernel and user-space for reliable power management.
Ever wondered how Linux knows exactly how to power off a GPU or wake your Wi-Fi card? Meet ACPI — the quiet bridge between your laptop’s firmware and the Linux kernel that makes suspend and resume possible.
Explore Linux sleep states (S-states) in depth. Learn what they are, how they differ, their impact on performance and power consumption, and how to configure and monitor them for optimal system efficiency.
Power management in Linux is a chain of hardware, ACPI, kernel, systemd, desktop, and apps working together. Learn how these layers interact to deliver smooth suspend/resume and long battery life.
After nearly a decade of loyal service, my Dell XPS 15 9550 got a major birthday upgrade. From fixing a sticky panel to adding new Wi-Fi, RAM, and storage, I brought this old warrior back to life—and it’s now ready for another decade of work.
