Also, they measured the silicon die area for all motherboards and 30 DRAM cards produced over roughly the same period (until 2011). The scientists disassembled 11 laptops of similar size, made between 19, and weighed the different components. A 2015 research paper discovered that the embodied energy of laptops is static over time. You are forgiven for thinking that this “most recent life cycle analysis of a laptop” is outdated, but it’s not. The study cited dates from 2011, and it refers to a machine made in 2001: a Dell Inspiron 2500. 3 My 5.7 years per laptop experience is not exceptional. The average laptop is replaced every 3 years (in business) to five years (elsewhere). Most of the 160-200 million laptops sold each year are replacement purchases. The high resource use of laptops is also because they have a very short lifespan. The production of microchips is a very energy- and material-intensive process, but that is not the only problem. 2 The making of a laptop also involves a high material consumption, which includes a wide variety of minerals that may be considered scarce due to different types of constraints: economic, social, geochemical, and geopolitical. Using the data above, this means that the production of laptops requires a yearly energy consumption of 480 to 868 petajoules, which corresponds to between one quarter and almost half of all solar PV energy produced worldwide in 2018 (2,023 petajoules). 1Įach year, we purchase between 160 and 200 million laptops. According to the most recent life cycle analysis, it takes 3,010 to 4,340 megajoules of primary energy to make a laptop – this includes mining the materials, manufacturing the machine, and bringing it to market. Not buying new laptops saves a lot of money, but also a lot of resources and environmental destruction. In this article, I explain my motivations for not buying new laptops, and how you could do the same. That’s more than 10 times less than the cost of my previous laptops. If my 2006 laptop lasts as long as my other machines – if it runs for another 1.7 years – it will have cost me only 26 euros per year. Including a new battery and a simple hardware upgrade, I invested less than 150 euros. Instead, I switched to a 2006 second-hand machine that I purchased online for 50 euros and which does everything that I want and need. In 2017, somewhere between getting my office and my website off-the-grid, I decided not to buy any more new laptops. The average useful life of my three laptops was 5.7 years. Between 20, I consumed three laptops that I bought new and which cost me around 5,000 euros in total – roughly 300 euros per year over the entire period. Although 10.4Fx will tell you when an update is available, you must download updates manually at this time.Image: Low-tech Magazine is now written and published on a 2006 ThinkPad X60s.īeing an independent journalist – or an office worker if you wish – I always reasoned that I needed a decent computer and that I need to pay for quality.Please use your system's crash logs if you are reporting a reproducible crash, or (if you are able) provide a gdb backtrace. Crash reporting is intentionally disabled to avoid polluting Mozilla's crash tracking system with our reports.Please note that Mac OS X Server is not supported currently. Printing may crash the browser on Mac OS X Tiger Server (issue 279).See issue 5 for notes specific to the font issue. See TechnicalDifferences for the complete list of changes necessary for 10.4Fx. 10.4Fx does not currently support WebGL, WebRTC or the webapp runtime, and scripts such as Arabic or Indic requiring glyph reordering or language-specific ligatures may not appear correctly.For a list of supported webcam devices, see VideoDeviceSupport. Not all webcams are supported in addition, multiple webcams may not all appear depending on how they are connected (issue 221).Personas and certain custom skins may hide the 'traffic light' window buttons, but they are still present and will work if hovered over or clicked on (issue 247).A fallback font will be used in their place. Bitmap-only fonts (usually Type 1 PostScript) cannot be used by the 10.4Fx font renderer and are automatically ignored by the browser.Systems with large numbers of fonts installed may experience intermittent pauses.TenFourFox uses a lighter chrome for windows and dialogue boxes than prior versions or the official Mac Firefox.See PluginsNoLongerSupported for an explanation and suggested workarounds.
