A new to me but old laptop
· 7 min readI’ve been using an older Lenovo Thinkpad T460p laptop that I bought brand new May 2017 for $2210 USD with a pretty impressive discount for the time. The Thinkpad T460p released April 2016 over a year earlier from when I bought it. I over bought on the CPU/processor and bought extra power adapters and batteries upfront. It has been a great laptop but starting to show its age and I’ve been looking for a new laptop with a little more pep. Older USB is starting to be limiting and I’d like to go beyond 32Gb RAM.

As I looked around, nothing under $4000-$5000 USD seemed to fit the bill once I added all the features and limitations. MacBook Pro and several WinTel laptops were in the running but nothing seemed like a good fit. And all the newer laptops seem to have soldered memory or limitations on future upgrades built into them. Add to that my interest in LLM and AI/ML which has me thinking about buying a used server or high-end workstation with multiple GPUs that will cost in the multiple $1000’s USD, I figure I should economize on my development laptop.
So that puts me browsing in the used market space on eBay and Craigslist.
A brief perusal brought the Lenovo Thinkpad T480 to my attention. The T480 as a January 2018 release is still an upgrade of my existing T460p that released in early 2016. I have a good bit of experience disassembling the base T-series platform as a bonus. The T480 are coming off support for large corporations and US Federal contracts. That brings the price way down in the used market.
Some key features are the T480 have an Intel i5 or i7 options in a Gen 8 CPU with and without a Nvidia GPU. It is the last generation of the T-series with removable batteries and has dual SODIMMs not soldered to the motherboard if you stay away from the slimline Ts-series.
