Windows 11 Upgrade Challenges on ThinkPad T480
Upgrading two ThinkPad T480 laptops to Windows 11 exposed hardware-specific performance regressions, a broken Logitech C930e webcam, and the counterintuitive fix of switching from Best Performance to Balanced power mode.
Thinkpad T480 WWAN SSD
Adding a 1TB NVMe SSD to the ThinkPad T480's WWAN M.2 slot using a 2230-to-2242 B+M key adapter — a cheap way to get a separate data volume for LLM models.
New Laptop update
All T480 upgrades complete: 64GB RAM, 4TB NVMe, WiFi 6E, IR camera, backlit keyboard, and 72Wh extended battery. A used laptop that now outperforms what I could buy new at twice the price.
A new to me but old laptop
Upgrading from a 2016 ThinkPad T460p to a used T480 for $670 all-in: 64GB RAM, 4TB NVMe, WiFi 6E, and a GPU capable of running LLM models.
