Sony Recalls 73,000 Vaio Laptops Due To Burn Worry
alphadogg writes "Sony is recalling 73,000 Vaio TZ laptops because of a possible manufacturing defect that may cause them to overheat, the US Consumer Product Safety Commission said Thursday. The recall relates to a problem with wiring near the computer's hinge, which could short-circuit and overheat in certain circumstances, perhaps burning the user. One person has suffered a minor burn as a result of the latest defect, and Sony has received 15 other reports of overheating computers, according to the Commission."
Manufacturing doesn't just put wires wherever. This is clearly a case of Sony calling it a manufacturing defect to cover their legal asses in case of Class Action lawsuits.
They can then allege that this was only in X thousand laptops because they were built wrong, not because they were designed to be wrong.
At least they weren't shipped with rootkits! Well, I THINK they weren't but how could you know?
I know that after being rooted by a music CD, I'll never have a Sony product burn me (except maybe my TV, which I bought before being burned by XCP). Once bitten, twice shy. Other corporations should take heed.

Users generally get burned for buying Sony anyway.
...take off all those illegal Sony Music MP3s you've downloaded before you return it.

I think their quality started becoming a joke about the time they put out their XPlode line of car audio equipment. Sony used to produce car audio systems that were really good back in the day, I think this was a company wide shift in focus. Increase sales volume on lower cost equipment and they cut their quality in the process.
I know exactly what happened. Follow along. Prior to about 1990, most electronics systems were made of more parts (less system on a chip type stuff) and the technology for putting those parts together was different. When you use a 4-7 layer board, with lead containing solder, and few if any surface mount components, the connections are more reliable. Some might argue, but it's true. The technology for using lead free solder and surface mount components is almost an art. You're not going to get joe at the tv repair shop to fix your mp3 player very often these days. Consequently, design techniques and technology also changed. Reliability is not something they design in for the 'lifetime' of the device because life expectancy is not 15 years any more, it's about 3 years tops. It's not designed for obsolescence, it just happens that way, so 15 year reliability is not a big bonus anymore.
With surface mount components and technology, most consumer devices have become 'throw away' technology. That is to say it's cheaper to build a new one than to repair the broken one. It's been that way for some 15+ years. So it has become a gamble: make something that lasts long enough for the next model to come out, just replace any defects. Most "repairs" in the last 15 years are nothing more than putting a new case on the outside. Note that Apple has had some problems as have other manufacturers. The Razor sucked as an example.
Despite many such failures in consumer products, I have yet to find anyone complaining bitterly about Panasonic or sharp. Does anyone have horror stories from them? Sharp makes the Sidekick, and I have to say I'm rather impressed with that product.
This is why extra warranty time is a rip-off. If the product is going to fail, it will fail in the first year, if not, it will probably last for 7+ years... well past typical usefulness to most markets.
RoHS in manufacturing programs are also causing things to happen that will bit by bit reduce long term reliability. That's just how it is. Perhaps some nanotech will come along to fix the problems induced by current manufacturing technology trends. I hope so.

I think the recall relates to something more than the general trend toward laptops running hotter...
But to your point, a few things.
First, heat as waste energy... well, sort of. All of the energy that goes into your computer comes back out. (Remember, using energy doesn't mean the energy is gone.) If we exclude the energy that's deliberately converted to light for the monitor, a good chunk of that is ultimately coming out as heat regardless of what happens to it in the mean time.
Yes, a more energy-efficient processor (and other hardware) will run cooler, all else being equal. However, dividing the energy that goes into a computer into "useful" vs. "waste heat" isn't really accurate.
But my real point is, it's not as if a laptop today is equivalent to a laptop 5 years ago except less energy-efficient. Newer laptops are smaller, which makes it harder to dissipate the heat generated. Also, processors are faster (and by other measures "more powerful"). Transistor counts go up, so does power consumed... and again, "consumed" mostly means "dissipated as heat".
I wouldn't say that we're "designing hotter laptops"; I'd say we're designing smaller/faster laptops and increases in efficiency haven't kept up wtih the level of cool running we'd become acustomed to.
