I'm really happy with this machine. It arrived carefully packed, and the seller even included a brand new mousepad. The laptop itself is in excellent condition, with only the tiniest hints of wear. It could almost pass for new. The inside was also clean, with only a small amount of dust to blow out of the CPU fan.The one shortcoming was a weak battery, which provided only 1-2 hours of run time. Based on previous reviews, that was something I sort of anticipated. Here's a summary of what I've done to beef the machine up at an extra cost of about $80:(1) Replaced the battery with a new third party replacement (search Amazon for "60Wh F3YGT Laptop Battery Replacement for Dell Latitude 7480"). I'm still running through the first few cycles of conditioning, but it looks like I'm getting around 5 hours of casual use right now. I was hoping for closer to the 13 hours boasted when these units were new, but that's not bad. It may improve with conditioning, and you can further increase battery life by making tweaks to your power settings, and / or turning off things you don't always need on, like BlueTooth or Wi-Fi.(2) Booted up Windows long enough to install the latest Dell BIOS update for the Latitude 7480. This is a good idea as it addresses both performance and security issues.(3) Replaced the original 256GB SSD with a much faster 500GB NVMe. I considered upgrading the RAM (it'll take 32GB maximum), but both slots have 8GB DIMMs on this machine, and upgrading would require buying two new modules. I may revisit that idea later on.(4) Installed Linux Mint 21.1.One reviewer wrote that because this laptop doesn't support Windows 11, it would have to be trashed after Windows 10 support ends in October 2025. This is partially correct, but only if you choose to run Windows on it. You can download and install one of the many free distributions of Linux, which takes care of the obsolescence issue entirely. Linux Mint is one of the more user-friendly and popular distributions so it makes an excellent choice.This laptop is more than capable of performing a variety of tasks capably for years to come when you take Microsoft out of the equation.TL;DR It's a good laptop, but plan on buying a replacement battery.
