The next step is to refurbish the main unit itself. Even though I was equipped with the service manual, I was a little hesitant owing to the My Links About Me Publications and Appearances Contact Me Legacy Site Facebook Twitter YouTube LinkedIn possibility of breaking something which could be hard to source, or making it worse than it already is. Nothing ventured, nothing gained, I suppose. Google Scholar I’m aware that others have done the same to their PowerBook 100s and seen positive impacts. It’s hardly surprising when you consider its age. Some were even nice enough to draw out capacitor maps for the boards. Even though I’ve seen them, I decided to “go it alone” and instead base my repair on my own teardown and analysis. Terms of Use & Privacy Policy This post will seem a little “jumpy” as both teardown and repair are interspersed, but I feel that’s probably the best way to present it. Required Material and Methodology ORCID ID element14 Community Blog Interesting Links Categories Audio Computing DIY Electronics Event Flash Memory Lighting Obituary Opinion Photography Power Bank I suppose if you’ve never done any soldering or re-capping of electronics, it’s probably not a good idea to start with a piece of equipment that you value. That being said, from my experience working with the PowerBook 100, it definitely rates a moderate-to-hard difficulty compared with some other work I’ve done. Radio Raspberry Pi Salvage Satellite Tablet Tech Flashback In order to get the job done, the tools you should have include: Telecommunications Travel Uncategorized A set of Phillips head screwdrivers of various sizes for laptop disassembly. A fine-tipped soldering iron, preferably of the temperature regulated sort. Some solder, 60/40 tin-lead type works well. High quality desoldering braid – I personally use Chemtools branded wick, but formerly used Goot which varies a little in quality. Good wick really makes the job easier, bad wick can leave you very frustrated. Desoldering bulb (or solder sucker) – the bulb type seems to be more useful as you can “blow” the holes open or “suck” them clean, whereas the pen type is really “one shot” with one hand and hardly easy to get into position. Hot air gun (preferable, but not essential) for removing the SMD components with more ease. Foil (I didn’t have this, but I probably should have) to mask sensitive portions of the board during hot air rewo…
