empaler writes "Apple has long denied service on iBook G4s whose screens went black after just over one year of use, denying that there was any error. But now, the Danish National Consumer Agency has released a report proving that the error is due to a design flaw. So far, the only news site picking this up is The Register (unless you understand Danish). The Danish Consumer Complaints Board says that Apple needs to get a grip and acknowledge this error in the rest of the world. The NCA also has some photos from the report (explanations in Danish, but easily comprehensible from context)."

It won't cover parts that are normally considered to have a somewhat short lifespan, like batteries. But in other regards it is held to the same standard as other household items that are meant to last, like fridges, etc.

Why should I be forced to pay extra for a hard drive that will last 5 years if I just need something that will last 18 months?
There is an opportunity (hidden) cost to everything; and spending the money to overbuild something for the job has almost as much or more opportunity cost.
Example: you can build a bridge that lasts 5 years, 15 years, 25 years, or even 100 years. Yes, 100 years. It is feasible. So why not build every bridge to last 100 years?
The answer is because if you build the bridge for 100 years but traffic patterns change after 10 years you've wasted the money. And in 50 years when flying cars are in use (har) you'll be really sorry you wasted all that money on the bridge to nowhere.
So -- moral of the story is that strong consumer protection laws have a specific use, but it isn't always the best possible outcome to employ them heavily.

Incidentally, with the introduction of RoHS-compliant lead-free solder, you will see this more and more. Consumer-grade lead-free is so crappy that it's almost impossible to make a single working board without at least some reflow work. Oddly enough, military- and medical-grade equipment are exempt from needing lead-free solder. Wonder why?

That said, it's clearly a design defect, and should have been fixed by Apple just like the G3 iBook.

A dry joint on thousands of units is a design flaw (Score:5, Insightful)
Engineers take *every* component of a product into account during design, including the types of solder to be used and the methods of soldering to be employed.
Indeed, they may select higher quality solder in order to reduce the requirements and hence the cost of other parts, or they may specify lower quality solder in the knowledge that the rest of the components on their bill of materials can still be assembled to spec and will still work together reliably for the normal lifetime of the product.
In this particular case, either Apple engineers did not consider the effect of their design on the solder joint in question (it should probably have been a far more substantial joint), or they did not specify the right type of solder given the requirements of their design, or else the subcontractors who made the unit used a type of solder different to that specified by Apple. (In the latter case this would be an Apple testing/QA problem, since you *ALWAYS* check what your subcontractors are doing, no exception. If you value your brand name, that is.)
So whichever way you look at it, this is entirely Apple's fault. Design and/or testing engineers get paid for doing a good design and/or testing job, and in this case they haven't. Get the message to them, and they'll fix it --- engineers are always happy to fix problems, on principle.
As for Steve Jobs and Apple Customer Services
There's a problem. Get it fixed.

So... an engineer is told to design a ship. He's told that the material to be used is wood, but designs it as if it were to be made of steel (because that's the right material!). The ship fails. How is it not the engineer's fault for not designing the system to the intended specifications? If the specs said that a non-lead solder was to be used, then the board should have been designed so that it would not fail with a non-lead solder.
Maybe they swapped out the solder after the design was finalized and it's not the designing engineer's fault. But you can't blame the failure on the solder (unless it was not the correct composition). It's not as if this lead-free solder is some mysterious substance. Someone, somewhere along the line, failed in the design of this system.

Understanding the constraints and setting specific definitions around terms like "prematurely" contribute inputs to the engineering process. In the end, if you release a product that breaks too soon, you messed something up and have a defect.
All of which is fine, if you then respond by revising either the design or the manufacturing process and fixing people's broken computers, which is not what Apple has tried to do.

And all Macs come with a one-year warranty against manufacturing defects. Any other measure of "too soon" is just personal opinion. I expect that Apple repaired all iBooks that failed within the warranty period. Apple makes no statements on the useful life of their products beyond their warranty statement, AFAIK.

Got any proof of that wild accusation? Remember, Apple contracts board manufacturing to third parties. I doubt that Apple has sit idly by and done nothing, but that doesn't mean that Apple would have been successful in anything they tried either. Sometimes technique changes (like lead-free solder) give some manufacturers headaches.
Besides, have you heard about this issue on the new MacBook or MacBook Pro systems, which have been in the market over a year now? Seems like Apple had some improvements made, then, if bad solder joints were the root cause of the iBook issues.

And on the other hand, there are anti-mac people that are excited about this sort of news. That's stupid, too.
But really, the anti-MS and anti-PC and anti-Mac stuff gets really old after a while. Macs have problems, PCs have problems, MS software has problems; I have to say that with this particular instance, Apple supporters seem much more worried about admitting that there is a problem than PC supporters or MS users.
Modding something flamebait for pointing out an inconsistency in how problems with company X are accepted is... hmmm. Silly.

Thank the European Union for this. Seriously. (Score:5, Informative)
To say that I spend a lot of time looking at soldered joints is an understatement.
So, what's the problem here?
The Danish government is just as culpable as Apple is on this one.
The solder used in this joint is obviously (to me at least) a lead-free solder. (Lead free solders are exceptionally grainy and dull in appearance compared to leaded solder that is smooth and shiny.) The switch to lead-free solders was mandated to occur last year on July 1st by the European Union. Any electronics shipping into EU member nations must comply with this new standard, which is called RoHS, or "Reduction of Hazardous Substances". (Look it up in Wikipedia.)
Due to complexities in maintaining parallel manufacturing lines, most companies simply switched to the Lead-free solder for their entire product line. (As did my company). This means that most all new electronics you by are going to have lead-free solder holding them together.
So, why is this a problem? Plasticity.
Leaded solder alloys (SnPb 60/30) are extremely ductile. This means that they will flex a considerable amount before fracture occurs. With electronics that experience heat cycles, or any kind of motion at all, this is an extremely beneficial trait to have. Lead-Free solders on the other hand (like the most common SAC305 SnAu3%Cu0.5%) are incredibly brittle. What is obviously happening here is that the heat cycling from the laptop turning on and off is stressing this solder joint, and causing the joint to fail. Had this been leaded solder, I can almost guarantee that this problem wouldn't exist.
So what does this mean? Exactly what the electronics industry has feared. The EU made a dip$#!t move. Industry experts believe that the average lifespan of an electronic device has been significantly diminished. Down to an average consumer product lifespan of 5 years. There have been early reports of serious quality problems, including SWATCH having over 10,000 watches fail within a month of shipping. You can expect to see a drastic shortening of the lifespan of your electronic goodies. This is just the beginning people. If you see a device that is labeled as RoHS compliant, do not buy it if you expect to use it for more than a few years.
