I buy the last of the great Thinkpads

...just in time

Based on this article, my decision to buy a ThinkPad T480 and upgrade it to 16GB of RAM was not just wise, it was the perfect smartsizing strategy. This article is playing catch-up to smartsizing advice we've been giving for years.

Why the T480 is the last of the great Thinkpads

The T480 I bought has an Intel Core i7-8550U, part of the 8th generation of Intel CPUs, officially supporting up to 32GB RAM. At the moment upgrading to 32GB RAM would cost between £170-240.

I am part of a tradition of enthusiasts and smartsizers who understand that these business-class machines are built with robust, over-engineered hardware that often has more to give than the manufacturer admits. My decision to upgrade to 16GB in the T480 puts me squarely in the sweet spot of performance, cost, and proven reliability, while knowing I have the option to push it even further - at least to 32GB RAM down the line if I ever need to. Most of the laptops Isaw at the walkround Curry's above are consumer machines. These are designed to a pricepoint, to be bought, used for one or two years or maybe even three years by which time they will be sluggish or 'outdated' just as Windows 11 has rendered so many machines 'obsolete'. As mentioned earlier, they cannot be upgraded.

The X230 I use as one of my 'daily drivers' was released mid 2012; 13½ years ago (!) at time of writing this, Feb 2026. The T420/520 released a year earlier were the last Thinkpads where one could upgrade the processor. With this T480 (2018) it's possible to upgrade RAM, change internal battery, even hotswop external battery, swop out keyboard easily. Despite being slim like modern-era laptops the T480 is notable for its extensive port selection (so no donglegate!) including Thunderbolt 3, full-sized Ethernet, and HDMI, making it highly versatile without needing adapters. It also has has an SD/microSD card reader as well as a headphone jack.

the T480 is regarded as the last of the great ThinkPads because it's the final model to combine the legendary keyboard, supreme user repairability, unique dual-battery system, and classic robust design before Lenovo pivoted towards thinner, less serviceable, and more homogenized ultrabooks. It's the ultimate expression of a philosophy that prioritized function, durability, and user control over sleekness and thinness.

Here’s a breakdown of why my purchase is so sound, echoed in the article's warnings:

Sidestepped the "Memory Crunch" Entirely
The corporate shift to Windows 11 and subscription-based Microsoft 365 is creating a massive demand for more RAM. Businesses are refreshing their old 4GB and 8GB machines because 4GB is now unusable and 8GB is the new bare minimum.
I bought an 8GB machine that came with easy affordable options to upgrade RAM up to 16GB and 'officially' up 32GB. The Result: This means I'm future-proofed against the exact memory crunch the article describes. While others are struggling with sluggish 8GB machines, my 16GB of RAM - upgradeable to at least 32GB - provides a smoother experience for Windows 11 (although I won't be using Windows in my case, and get even more mileage from RAM with Linux), modern web browsers, and productivity software.
Capitalized on the "Refurbished Gold Rush"
The article highlights that the demand for refurbished business laptops like the ThinkPad T480 is soaring because they offer incredible value. Companies are dumping these capable machines, making them a bargain for savvy buyers.

the quintessential business laptop now widely available on the refurbished market
acquired a machine known for its excellent keyboard, durability, and serviceability for a fraction of the cost of a new one
buy into the exact market segment the article identifies as being in high demand.
Applied the smartsizer "Upgrade and Save" Mantra
The article's key takeaway for buyers is to purchase a base model and upgrade the RAM yourself. This is far cheaper than buying a machine with more RAM pre-installed. Indeed this os what I did way back in 2009 buying a 4GB MacBook Pro 2.53GHz and upgrading the RAM myself to the maximum 8GB.
My Action: I bought the T480 and then upgraded it to 16GB RAM for around £50, matching the RAM to machines I already have - a librebooted X230 and T520.
The Result: This is the most cost-effective way to get a high-performance machine. I likely saved a significant amount of money compared to buying a newer model with 16GB of RAM, while achieving a comparable or even superior user experience for daily tasks. When I took a walk around a Curry's PCWorld recently I was shocked how many new laptops were being offered with just 8GB RAM - and these were machines which could not be upgraded!

Conclusion: A Wise Decision Confirmed by the Market

Accordingly, this purchase was extremely wise. I didn't just rush out and buy any old used laptop; I executed a well-informed strategy based on market dynamics. The article confirms that I made the right move at the right time. In this librebooted Thinkpad T480 I have a durable, repairable machine with ample memory that will serve me well for years to come, all while avoiding the pitfalls of the current memory crunch and taking full advantage of the burgeoning refurbished market.

Could I even upgrade the T480 to 64GB RAM?

A well-known secret in the ThinkPad community: Lenovo's official specifications are often conservative, and the actual hardware is far more capable.

What I've experienced with my T420, X230, (succesfully upgrading to 16GB RAM) - and now my T480 (upgradeable to 32GB RAM and potentially even double that!) - is a classic example of this.

Why the Official Specs Are So Conservative

Validation and Testing Costs: To officially support a configuration, Lenovo has to test it extensively. When the T480 was released, 16GB and 32GB DDR4 SO-DIMM modules were either prohibitively expensive or didn't exist. They validated the hardware with what was available and cost-effective at the time. They are not going to spend money re-testing a 5-year-old laptop for 64GB modules.
CPU and Chipset Limitations (The Real Bottleneck): The true limit is determined by the memory controller in the CPU and the motherboard's chipset. For the T480, the Intel 8th Generation "Kaby Lake R" and "Whiskey Lake" CPUs officially support a maximum of 32GB of DDR4 RAM. So, while 64GB might be technically possible, it's operating far beyond the CPU's intended design spec.
Market Segmentation: Lenovo wants me to buy a newer, more expensive laptop if one needs top-tier specifications. Limiting the official specs of older models helps push their new product lines.

The 64GB Reality for the T480

How it Works: The T480 has two RAM slots. By installing two 32GB modules (for a total of 64GB), users have reported that the system recognizes and uses the full amount.
The Catch: This is an unsupported configuration. The caveat is that, while it may work perfectly fine, it's not guaranteed. Stability can sometimes be a question mark, and one is relying on the modules being compatible with the system's firmware. It's a bit of a "your mileage may vary" situation, though many have had success.

My Legacy of Upgrading Older ThinkPads

T420/T520/ X230: The official max was 8GB (2x4GB). However, the 2nd Gen Intel Core CPUs in those machines actually supported 16GB. The limitation was purely that 8GB DDR3 SO-DIMMs were rare and expensive when the laptops were new. As they became available, users discovered the laptops worked perfectly with them.
