Why Modern Computers Are So Hard to Fix (And What Changed)

Short answer: computers shifted from fully repairable machines to sealed, largely disposable units because manufacturers chose thinness and integration over serviceability. RAM and storage get soldered directly to the motherboard, screws get replaced with glue and proprietary shapes, and software increasingly checks that a replacement part is the one it “expects” before it’ll work properly. None of that is accidental — it’s a design direction, and it’s had a real effect on how repairable the average computer is today.

Why older computers were easy to fix

• Modular parts. A hard drive, a stick of RAM, a power supply — all of it typically came out with a basic screwdriver and went back in the same way, no specialist tools or heat guns required.
• Standard pieces. A 3.5-inch hard drive, a SATA cable or a standard RAM stick largely fit across different brands and models, rather than being locked to one manufacturer’s exact part.
• Open guides. Manuals and service documentation were often published or reverse-engineered openly enough that a reasonably confident owner could fix things at home, or a local repairer could source and fit a generic part without a fight.

Why modern computers are hard to fix

• Glued and soldered. Batteries, screens and memory chips are frequently glued down or soldered straight to the main board rather than socketed, so what used to be a ten-minute swap can mean a full teardown, solvent, heat and a real risk of damaging something else in the process.
• Special shapes. Chasing thinner designs means custom-shaped batteries, non-standard screws and board layouts that don’t match anything sitting on a generic parts shelf — a replacement often has to come from the manufacturer, at the manufacturer’s price, if it’s available at all.
• Software locks. Some parts now check in with the motherboard using digital signatures or serial pairing. Swap in a genuine but “unpaired” screen, battery or storage chip and the machine can throw error messages or disable features until an official tool re-authorises it — a problem that never existed when a part was just a part.

What this looks like on the bench

It’s not abstract for us — we see it regularly. Soldered memory means a machine is stuck at whatever RAM it shipped with from the factory; there’s no bumping a sluggish laptop up with a cheap RAM upgrade the way you could once assume. It also removes one of the most basic diagnostic and repair steps there is: pulling a RAM module to test it or swap it out. A loose or faulty stick used to mean unclipping it, testing with a known-good spare, and clipping the replacement back in — a quick, inexpensive fix. With memory soldered directly to the board, the same fault means replacing the entire system board, because the memory can no longer be separated from it. We’ve had a $1,500 laptop turn into a $500 repair bill for exactly that reason — a fault that would once have been a cheap RAM swap became a full board replacement instead, simply because there was nothing left to unclip.

This tends to be a consumer-retail problem more than anything else. A laptop built to sell cheaply off a shelf is designed around thinness and price first, with serviceability an afterthought at best. Ex-business and ex-government machines — the kind that come off a corporate lease or a government refresh cycle — are usually a different story: bought under contracts that expect a multi-year warranty, on-site repairs and parts availability, they’re far more likely to have socketed RAM, standard drives and screws instead of glue. It’s a big part of why the secondhand business and government stock we sell tends to be some of the more genuinely repairable gear that comes through the workshop, not just the cheapest.

A different kind of rigid system

There’s a scene in the film A Man Called Otto where Tom Hanks’ character gets into it with a hardware store cashier who can only sell rope by the yard, not the 5 feet he actually wants, because the register isn’t set up to do anything else. Otto’s not wrong about the maths — he’s just up against a system built for the store’s convenience, not the customer’s actual need. A soldered RAM chip or a battery that won’t work until an official tool “approves” it is the same idea with better marketing: you don’t get the 5 feet you need, you get whatever the system’s decided to sell you.

Why it matters, beyond one repair bill

A machine that can’t be opened doesn’t just cost more to fix — it often doesn’t get fixed at all. A swollen battery or a failed 256GB drive that would once have been a small, cheap swap can instead mean replacing the whole computer, because the part that failed was never meant to be separated from the rest of it. That’s a real factor in electronic waste, and it’s a big part of why “right to repair” has become an actual regulatory movement rather than just an enthusiast complaint — the EU has started requiring easily removable batteries and banning software part-pairing in some device categories specifically because of this trend. iFixit’s original Self-Repair Manifesto put it plainly years before regulators caught up: if you can’t fix it, you don’t own it — you’re leasing it from the manufacturer on their terms.

Where Australia sits on this

Worth being clear-eyed about: unlike the EU, Australia doesn’t have a right-to-repair law covering computers or consumer electronics. The only sector with a dedicated scheme is motor vehicles, and agricultural machinery is set to be added from 2026 — everyday laptops and desktops aren’t covered by anything equivalent. The Productivity Commission looked at exactly this gap back in 2021 and recommended a repairability labelling scheme for consumer electronics, similar to what France has already introduced — but for now, a manufacturer choosing to solder everything down or lock parts to a motherboard faces no legal requirement in Australia to do otherwise. What you get here still comes down to Australian Consumer Law guarantees (a product has to be of acceptable quality and last a reasonable time) rather than any specific right to open it up and fix it yourself.

What it means for you

• Desktop towers are still the most repairable and upgradeable option going, by a wide margin — see SSD upgrades in Townsville for how much difference a simple, modular upgrade can still make
• Laptops vary enormously by brand and model — some still use standard, socketed RAM and swappable drives, others solder everything down
• A glued battery or soldered chip doesn’t automatically mean a machine’s not worth fixing — it just means the repair needs the right tools and know-how, not a basic screwdriver — see is a 7-year-old computer worth fixing?
• If you’re buying new, checking a model’s repairability before you buy is a genuinely useful five-minute step
• Ex-business and ex-government machines are often built with repairability in mind from the start, unlike a lot of budget consumer retail stock — see our refurbished and second-hand computers
