The short answer
Section titled “The short answer”Replace when two of these three are true:
- The OS is out of support (or will be before the next replacement cycle).
- A repair costs more than a third of a replacement.
- The workload no longer fits (RAM ceiling, no NVMe, no TPM 2.0).
Repair when the machine is supported, the fault is a single known part, and the rest of the platform still meets your needs.
Support status comes first
Section titled “Support status comes first”Hardware does not fail on a schedule; software support does. Microsoft publishes lifecycle dates, and they decide more than the spec sheet:
- Windows 10 is past end of support — a Windows 10 machine is a compatibility test box, not a daily driver.
- Windows Server 2022 mainstream support ends 2026-10-13; 2019 and 2016 are extended-only.
- Windows 11 requires TPM 2.0, Secure Boot and a supported CPU — older platforms cannot be upgraded at all.
A machine that cannot run a supported OS has a hard deadline regardless of how fast it feels.
The repair-versus-replace arithmetic
Section titled “The repair-versus-replace arithmetic”| Repair | Compare against |
|---|---|
| Battery (laptop) | 10–20% of a replacement — usually worth it |
| SSD | 10–15% — worth it, and it makes the machine feel new |
| Keyboard/screen | 20–40% — depends on the rest of the machine |
| Motherboard/GPU | 50%+ — replace |
| Data recovery | separate decision; back up first |
Add the time cost: a repair that takes two weeks without a machine is often more expensive than the part.
Upgrade paths before replacement
Section titled “Upgrade paths before replacement”These extend life cheaply:
- RAM to the platform max — the single most effective upgrade for a 4–8GB machine.
- SATA/NVMe SSD — turns a 2016 laptop into something usable.
- Battery — restores the “laptop” part of a laptop.
- Thermal paste + cleaning — recovers lost performance and noise.
These do not extend life:
- An external GPU on an old platform (bottlenecked).
- More cores via a CPU swap on a dead socket.
- Windows “debloat” tools to compensate for 4GB RAM.
The TPM/Secure Boot cliff
Section titled “The TPM/Secure Boot cliff”Many otherwise-fine machines from 2015–2017 lack TPM 2.0 or a supported CPU for Windows 11. That makes them:
- fine as a Linux box or a lab machine;
- unsuitable as a machine you depend on for supported Windows work.
A decision table
Section titled “A decision table”| Situation | Decision |
|---|---|
| < 3 years old, one part failed, in support | repair |
| 4–6 years old, SSD/battery tired, OS supported | upgrade (SSD/RAM/battery) |
| 6+ years, OS out of support | replace |
| Cannot run a supported OS at all | replace or repurpose |
| Repair > 40% of replacement cost | replace |
| Only machine, holds critical data, failing intermittently | replace first, diagnose later |
What to do with the old machine
Section titled “What to do with the old machine”- Repurpose as a lab/NAS/backup target — see retiring and wiping.
- Donate only after a proper wipe.
- Recycle through an e-waste channel; do not bin a battery.
