Five ways manufacturers make devices hard to repair

1. Tamper-resistant screws

Our first self-repair roadblock, tamper-resistant screws, aren’t new or unique to computers, but manufacturers are using them on a lot of devices. Nintendo used tri-wing screws on the Wii and Gamecube. Sony used special security torx screws on the slimline PS3. And, Apple uses pentalobe screws on the iPhone, MacBook Air, and Retina MacBook Pro.

Luckily, this roadblock is also the easiest to overcome. With a little online research, you can buy a driver or bit to handle any of these screws.

2. Glued-on components

Unfortunately, some manufacturers are abandoning screws altogether–choosing to glue components in place. And, that’s our second roadblock.

Whether is the iPad’s front panel, Galaxy S III’s ribbon cables, or Retina MacBook Pro’s battery, removing glued-on components can be difficult and risky. And, it’s best not to remove a working component that’s glued in place. If you absolutely must do so, heat can sometimes help weaken the adhesive, but should be used very carefully.

3. Tiny, fragile connectors

If glued-on components weren’t enough, today’s gadgets are also filled with tiny, fragile connectors.
Whether it’s a board-to-board connector or flexible-flat-cable connector, tablets and smartphones are filled with them. The keys to working around this roadblock are a little patience, a light touch, and a few really thin tools.

4. Battery soldered to the motherboard

Up to now, I’ve been able to help you overcome the repair roadblocks on our list. But, the last two aren’t as easy to work around.
At number four is a roadblock that manufactures are using less frequently, but that still appears from time to time–batteries that are soldered to the motherboard.
Favored by some tablet and smartphone manufacturers, there’s no way to replace a battery like this without using a soldering iron or wire cutters. Replacing a soldered battery is definitely an advanced do-it-yourself fix.

5. Fused front/panel display assembly

Lastly, there’s one repair roadblock that’s almost impossible to overcome. And unlike soldered batteries, device manufacturers are actually using it more frequently. It’s a fused front panel and display assembly.
Whether it’s on the Apple iPhone or Google Nexus 7, a fused front panel and display assembly makes repairs more expensive. Because, if one component breaks, you have to replace both. And while it’s sometimes possible to separate the two components, you often risk damaging the working half in the process. It’s just not worth the risk.
