Repurposing old laptops as thin clients can raise long-term costs

The hidden costs of repurposing old laptops

Businesses that turn ageing laptops into thin clients may end up spending more than if they had bought purpose-built hardware, according to a TechRadar Pro comment piece published on 13 November 2026. The article was written by an IT product manager and cloud device business manager at LG Electronics, so readers should note the author works for a company that sells computing devices.

A thin client is a device that runs software and services from a central server rather than locally. Users reach their desktop over the network, so the machine in front of them needs little processing power or storage of its own. The argument in the piece is that giving this role to an old laptop looks like a saving but simply splits the cost of new hardware into smaller, less visible bills for repairs, support, downtime and electricity.

Why businesses repurpose laptops instead of replacing them

The practice has grown for understandable reasons. Software licences and tool sprawl put pressure on technology budgets, so extending the life of existing hardware can feel like the sensible option when money is tight. Sustainability targets add to this, because reusing devices appears to reduce electronic waste.

The market data cited in the article shows how common the approach has become. In Europe, devices that connect to a virtual desktop infrastructure, meaning a cloud or server-based desktop rather than a locally installed one, make up a significant share of the market. Of those devices, only about half are dedicated thin-client hardware such as purpose-built boxes or all-in-one units; the rest are repurposed computers.

As processing moves to the cloud, the laptop on the desk becomes little more than a screen that captures keyboard and mouse input and holds a network connection. That makes the hardware look dispensable.

Ageing hardware still fails, whatever it is used for

The piece gives a concrete example. A four-year-old laptop will typically have a battery running at around half of its original capacity, or worse. Even if the machine is given a lightweight operating system designed to run smoothly on weak hardware, such as a lightweight Linux distribution, that battery is expected to swell, fail or die completely within 12 to 24 months.

Battery failure matters more than it might seem. Replacing batteries, or leaving employees tethered to power sockets, removes one of the main advantages of thin clients, which is low maintenance. Laptops also carry parts that wear out: cooling fans, hinges, keyboards, trackpads and screens. None of these become newer because the processing has moved to a server.

By contrast, the article states that dedicated thin clients are built with solid-state components intended to last eight to ten years without a single physical failure. Where a thin client does include a fan, it works far less hard than the fan in a full laptop, which reduces wear over time.

The business impact of failing hardware goes beyond repair bills. Repeated faults generate helpdesk tickets, frustrate staff and cost productivity. The author describes repurposing as a one-time delay strategy rather than a permanent infrastructure model, with the eventual purchase of new hardware merely postponed by a couple of years.

Energy use and the sustainability argument

The most counterintuitive claim in the piece concerns the environment. Repurposing is widely assumed to be the greener choice, but the author argues the opposite is true over a full hardware lifecycle. A standard business laptop charger draws between 45W and 65W of power, while a modern dedicated thin client runs on just 5W to 12W.

Scaled across 2,000 users over an eight-year period, the article claims those energy savings alone can offset a large share of the hardware procurement cost. This is the author's own calculation rather than an independently verified figure, so businesses would need to model their own usage before relying on it.

Manufacturing emissions point in the same direction, according to the piece. Building a premium business laptop generates significantly more carbon than building a small, fanless thin client with an aluminium chassis. Over eight years, a dedicated thin client user needs exactly one device, while a laptop user is likely to go through two to three machines, roughly tripling the manufacturing footprint.

These figures come from a vendor-side perspective, and the article does not include independent testing. Even so, the underlying logic, that a low-power device replaced once a decade can beat a power-hungry device replaced every few years, is one that sustainability teams can check against their own data.

What it means for IT buyers

The core message for decision-makers is to judge hardware on total cost of ownership rather than on the invoice at the point of purchase. When laptops are repurposed, the article argues, the money saved on new devices is outweighed over time by repairs, lost productivity and the replacement hardware that becomes unavoidable a few years later.

The author's conclusion is that the organisations with the lowest long-term costs are those that invest in equipment purpose-built for the coming decade, rather than extracting the final usable days from machines that are already due for retirement. Given that the piece was written by an LG Electronics manager, businesses should weigh the argument against independent advice and their own cost modelling.

The practical takeaway is not that reuse is always wrong. It is that repurposing suits some situations better than others, and that a laptop pressed into service as a thin client carries ageing batteries, fragile parts and higher power draw that a purpose-built endpoint does not. Companies weighing the option should compare the full eight-to-ten-year picture, including energy, maintenance and replacement cycles, before deciding.
