Louis Rossman - Hilarious Technical Commentary w Teeth

[RumorConsumer]

This dude is hilarious. As a former repair technician myself I found his commentary to be mostly spot on, funny, and informative. Enjoy!

He doesn't make "technical commentary"

He doesn't know what he's talking about, he's a repairman, not an engineer.

While I do find some of his criticisms to be spot on, I think he has an axe to grind against apple. His reballing video he's saying Apple put in a timer to cause the Macs to fail because apple care is coming to an end. I stopped listening to that video after that comment. While I agree with him, that reballing is not repair, I couldn't stand his rhetoric.

Yes I agree that one was over the line. And as a tech who sees hundreds of machines his views aren't totally without basis. 2007/2008 MacBook pros died w their graphics issues around then as did the 2011 machines. But yes, that is conspiracy theory.

He's a user and a repair man yes, and he's consumer oriented which to me makes him fun to listen to.

Must be for you.

For me, he's a jackass that thinks and convinces people he's better than what he actually is.

Also, a liar, and that's what his audience likes to hear. Tim Cook must have stole his lunch.

 

[lowendlinux]

I like Rossman a great deal

There's no doubt that the Apple has had some significant issues with 2007 -> 2011 MBPs regarding the GPU and 2012 -> 2014 (or later?) with the coating wearing off on the display panel (staingate as some call it).

Like I said, I think some of his criticisms are accurate but I still think he does have an axe to grind against apple.

For sure x100. That part agreed.

He has.

Lots of computers have problems with GPUs.

But because they aren't Apple, nobody talks about them, don't generate clicks. And most people are fine, because most people don't buy PC's with GPU's, and the ones who buy, know how it is and don't whine.

That is so interesting. Ive been in the mac world for so long that never occurred to me. Got a link for a major PC maker GPU issue?

He knows a lot more than the average consumer or product reviewer.

There are some seriously questionable engineering decisions inside Apple's notebooks (presumably compromises at the request of design and marketing) that largely go unnoticed, except perhaps to the technicians that are tasked with fixing the machines on a regular basis who are often bound by an NDA.

However he goes about it, I'm glad someone's out there pointing out the flaws.

Also a repairman can have knowledge or experience in engineering. The best repairers are often the ones that do.

I'll eat my shoe if he ever participated in any engineering project!

No, he doesn't, he just hates the company and opens MacBooks and iPhones to find a reason to hate them more.

He never opens a HP and complains about the noisy fans or the many layers and many screws you need to go trough just to get to the board. Or that the SSD is also soldered in a Asus. He's just a mentally hill person with cognitive dissonance.

What more can one say about people that say Apple makes chips designed to fail after 3 years? Hundreds of millions (not exaggerating) of Apple devices out there with more than 3 years working just fine without any intervention ever.

I agree, he is showing some of the questionable decisions apple has made over the years and its ramifications.

While I do think he hates Macs, I think what he offers in terms of insight and how things work is beneficial

However he goes about it, I'm glad someone's out there pointing out the flaws.

Yes, I think more information is good for the consumer.

Unless you've been a repair person in a shop literally working on hundreds of machines a month its hard to convey the impact of the experience of watching the exact same part failure come in over and over and over again. Its like groundhog day. Same with the iMac bulging capacitors. Same with the MacBook 2006's top case chipping, optical drive failures, Seagate hard drive failures, LCD inverter failures, heatsink temp sensor failures, ALL of which affected tons and tons of units. So yes he for sure has an axe to grind and from his perspective he has a lot of information that many others dont.

I think I remember one instance where he said that, but I vaguely remember it being about a surface mount capacitor in some 2009/2010 models that had a shorter than expected mean time between failure (MTBF) rating. The component would fail somewhere around the three year mark. So Apple didn't engineer that component to fail, and that wasn't correct, but that component wasn't up to scratch and would on average last around that amount of time.

Of course, one shouldn't claim Apple engineered those boards to fail - that's speculation. Personally I think it was just an engineering oversight and nothing else.

BS!

Where did they get that?

I'm an EECS, never seen a capacitor with MTBF rating! The expensive stuff is designed to last forever, the cheap stuff doesn't have a datasheet.

That's pure BS. Some people hate Apple, but looks like he lives and works for hating Apple!

I have a MBP from 2010, and it still works fine to this day!

The component in question is a 2V 330uF Poly-Tantalum capacitor (B2 Package) at position C7771 (17" Mid 2009) and C9560 (15" Mid 2010) respectively. I believe Apple used Panasonic OSCON / POSCAP capacitors from their TPE series. Data sheet is available here:

http://www.farnell.com/datasheets/2059638.pdf

Some manufacturers specify an MTBF, but the more commonly used metric is the lifespan temperature or FIT (failures in time) rating, which in this case is +105 °C, 1000 h rated voltage applied. Panasonic capacitors are some of the best out there, but even those capacitors don't last forever.

The rails these capacitors reside only supply 1.05v, but are both situated next to the heatpipe and heatsink assembly, so they are subjected to rather high ambient temperatures. Consider that a MacBook Pro of that vintage idles between 55-60C, and under CPU/GPU load can increase closer to 85-90C. (I'm using one now, and those are my current CPU Die/Proximity temperature readings.)

In any case, rated or not, those capacitors were failing. Apple acknowledged the defect with a repair extension program in the 2010 models (https://support.apple.com/en-us/HT203554, still available on the Internet Archive) covering the machines for 3 years from the date of purchase. Unfortunately most machines started to fail outside of the 3 years. No extension program was issued for the Mid 2009.

I'm pleased your 2010 is still working - after all they weren't that bad a machine - but this was a common defect and one I saw frequently in Apple service. Within the repair program, some had their boards repaired free of charge. Outside the repair program, it was a thousand dollar Logic Board replacement.

Thankfully replacing that capacitor repaired the graphics issue, and I've repaired four Mid 2010 machines out of warranty with graphics anomalies by replacing that capacitor for about $3.22 each. That I could have learned by reading some of the board repair forums, but I happened to learn it from Louis Rossmann.

So his knowledge and insight is certainly worth something.

That's what happens when you read the data-sheet and you're not an engineer.

That's the life of the component if being constantly charged, those are signal capacitors, and are not constantly charged, the power capacitors, yes, are constantly charged when the device is powered on.

Does he tell his viewers when they (as usual with unauthorised repairmen like him), fix the problem temporarily, then after a few months, the problem persists?

Don't think so!

He doesn't have the qualifications to judge that.

If you watched the videos you would know that he does! With great depth and vigor. Please see this video at 8:15 -

Pretty much an entire tirade in this exact point. Cross examine?

...and you sir sound so much more 'qualified' too ha ha ha . What you hate you create,...it's not electronics son, it's psychology...stop projecting your inner **** onto others. You end up revealing more about yourself than what you can possibly imagine...ha ha ha .

Or the amateur psychology?

I was linked to this today for the first time.

It took five minutes of walking around dumbfounded for me to finally accept that someone thought the timer comment was literal, rather than a knock at that 4 year time period of buggy products.
2007-2008: 820-2101/820-2249 G84-603 issues, hinges screwed to frame rather than backplate issue.
2008: 820-2330/820-2532 C7771 no power issue issues, 820-2330/820-2532 split back glue coming off & de-constructing display assembly issue
2009: 820-2610 C7771 no power issue
820-2850 C9560 framebuffer/random crashing issue

the 820-2915 was the "cherry on top" of a five year long run of defective 15" macbooks.

People actually took that seriously
and then used it
to argue
conspiracy ????

like it wasn't dry humor about the poor longevity of that product... in the context of discussing their design/boards/assembly.... you actually took it seriously and literally, and then argued against that...

i will have to remember to put captions on the bottom of these videos like they do in commercials. along the lines of where they say in fine print "red bull doesn't actually give you wings, assume gravity always applies" for.... uhm.... certain people watching. yeah. i'll leave it at that.

good job!!!!
