FreeBSD 15.0 on the ThinkPad T480 — Efficient, Stable, and 8 Hours on Battery
Achieving near-Linux battery life on the T480 while staying purely BSD.
Welcome to Larvitz Blog! I’m Christian, a Cloud Consultant by day and FreeBSD enthusiast by night, with over 20 years in enterprise IT. Here I write about FreeBSD jails, PF firewalling, self-hosting, Linux system administration, and anything that’s cleanly engineered. Most articles are hands-on guides born from running my own infrastructure, from dual-stack networking and Ansible automation to hosting a Mastodon instance on FreeBSD.
