“Old” is a shape, not a number
A five-year-old business laptop with a socketed or replaceable RAM layout, a 2.5" SATA bay, and a service manual is a different project from a wafer-thin machine where storage is soldered and the battery is behind glue. Before you open your wallet, answer three questions. First, does the screen and chassis still pass the "would I be embarrassed on a call" test? Second, is the CPU doing real work for you, or is disk thrash and thermal throttling masquerading as slowness? Third, is the machine on an OS that will receive security fixes for the years you want to own it? If the answers are "fine," "mostly throttling," and "yes for a while," repair often wins.
SSD: the upgrade that repays the fastest
If the laptop still has a spinning hard drive or a tiny SATA SSD, moving to a 1 TB NVMe (where supported) or a SATA SSD in the 500 GB–1 TB class is the single largest quality-of-life jump for general office work, browser tabs, and light photo work. The parts market in Ireland and the UK in early 2026 is still competitive: an decent NVMe for everyday use is often in the €50–100 / £45–90 range depending on sales and the PCIe generation your board supports. The labour to clone or reinstall is either an evening with a USB caddy and Clonezilla or a workshop hour if you are not eager to touch BitLocker keys.
RAM: know your ceiling
8 GB of RAM in 2024–2025 is usable for a disciplined browser; 16 GB is the comfort zone for a sole trader with dozens of tabs, a local Docker or VM, and a Creative Cloud product open at once. If the motherboard maxes at 8 GB and the machine is not emotionally important, the RAM floor can end the repair story. If you can go to 16 or 32 with two SODIMMs, the price in European retailers is €30–80 a stick depending on speed and a volatile DRAM market. Soldered RAM is not a failure of character. It is a design choice that steers you to replacement sooner when Chrome and Electron are your daily bread.
Battery: cycles, swelling, and the cheap fix that is not
A battery at 60–70% of design capacity is annoying; a battery with puffy cells is a hazard and a structural risk to the trackpad and keyboard. In Dublin and Birmingham we still see "battery-only" €80–150 / £70–130 workshop bills for non-glue models, and €150+ on ultrabooks where display has to lift. Genuine parts are slower in post-Brexit supply chains, so ask lead times. If the machine thermal-throttles on battery but not on mains, also check the PSU is healthy before paying for a board you do not need.
Thermal paste: when it matters
Repasting a 5+ year unit can recover sustained clocks if the factory paste has dried and the heatsink is sound. The operation is a laptop strip-down, not a desktop afterthought. A bad pry on plastic clips is how bezels crack. The €5 tube in the corner shop is the wrong place to cut corners. If you are already inside for a fan clean, replace the pads on VRAM where present if they have gone crispy. A thirty-degree CPU drop is not guaranteed; a quieter fan curve often is.
What it costs, roughly, in Ireland and the UK
These are order-of-magnitude street numbers, not a quote. Screen replacement for a mainstream 14" 1080p panel is often €150–300 all-in, more for high-refresh or touch. A top case with keyboard and battery on certain Dell or Lenovo lines is a modular win; on some Apple Intel models from the butterfly years, a single key can still be a moral question. A workshop diagnostic in Cork or Bristol is often waived if you go ahead, but not always; ask. VAT and sole-trader politics are yours; the hardware maths stay similar.
When to stop feeding the project
- Soldered 8 GB of RAM and you need 32 GB of headroom for the next three years of work.
- Screen and hinge damage that approaches 50–60% of a sensible replacement after parts and labour.
- OS or firmware dead ends. Windows 10 is out of the picture for a 2026 buy; a machine stuck on a tired build with no TPM2 may still run Linux for a home lab but not for a client-facing laptop if BitLocker and policy patching are required.
A repair-first sequence that is boring on purpose
- Image the disk if it still spins.
- Check SMART or NVMe health in Linux or vendor tools. Bad blocks end the day.
- Add RAM to the spec ceiling if swap thrash and beach balls are the main symptom.
- Upgrade the SSD if latency and IOPS are the story.
- Replace the battery if unplugged life matters for the job.
- Repaste or replace the fan if thermals and noise are the last complaint.
- Check chassis and ports before spending on docks you will outlive.
A word on warranty and the right to repair
If the machine is still in warranty, open the chassis only after you have read the conditions. A warranty sticker is a policy point, not a debate. The goal of this post is to save Saturdays on upgrades that are mismatched to the machine you own, not to lecture anyone about e-waste in bold headings.
