  8. A $50 million supercomputer can also be taken out by a 1 cent diode failing. The same goes for every computer outside of specialized redundant systems for aviation or aerospace. Electronics either work perfectly, or they don't. It's not like Apple products are the only ones affected. I've repaired a shitton of failed PCs and PC laptops with single part failures.

  10. Hacked engine control modules are a thing. Google it. It's still a bogus complaint because these hacks exist without any documentation being provided.

  11.  @kapioskapiopoylos7338  That's not how redundancy in electronics works. The Zener diode that failed https://www.digikey.com/product-detail/en/rohm-semiconductor/GDZT2R6.8/GDZT2R6.8CT-ND/2075863 can fail in two ways, it could fail open or fail short and you can't just add extra "redundant" parts to deal with the case of a short. It shouldn't fail to begin with as it's rated for 100mW and in the circuit it should only be passing 1.74mW so it's oversized by 57 times. You can see physical damage to the package which is from the quality manufacturer ROHM Semiconductor and there is no way that could be from excessive current so the problem is likely physical damage caused by the encapsulating material Apple covered those 5 parts with. It looks like hot glue but I would have specified Silastic. It's also possible ROHM had a manufacturing defect; they still make these parts but they're flagged as NRND or "Not Recommended for New Designs" and they don't list a substitute.

  13. I have to laugh at all the people who practice this kind of "brand loyalty". I've been repairing ThinkPads since they were made by IBM and computers since before Louis was born which is why I'm using a MacBook from 2013 to type this.

  14.  @romancenturion8  I didn't say he did, but the video title is pretty specific and this is a MacBook, iPad & iPhone repair shop. Lots of posts here are pretty typical fanboi/hateboi whines I've been listening to since 1981 when it was IBM PC vs. Apple ][. It's getting old so I made sure I wasn't ambiguous. Apple screws up royally and regularly, but I tend to get about 10+ years of useful life of my macs and I run both MacOS and Windoze on them. I don't get that lifespan from any PCs other than Toshiba and PCs don't run MacOS unless you hack things. No thanks.

  15. I got my Apple service certification in the early 1990s and at that point all internal service parts were referbs. I doubt things have changed.

  17. The Thunderbolt controllers use QSPI Flash which has far lower durability than EEPROM but should have better retention. Those chips are made for firmware storage, not housekeeping data storage and In my view should never be written to outside the production process or a firmware update. Add some FRAM for setting storage. By the way... the Tesla OS does the same thing by constantly logging garbage to flash. Their firmware image is so large that there isn't any space left for wear leveling to work properly so the log data eventually destroys the flash and then Tesla wants a couple thousand dollars to repair things.

  18. It's even worse than reduced functionality because this affects almost 40 Lenovo models and all the most recent ones use the USB-C port (which the Thunderbolt controller runs) for charging. Once the port fails, so does the ability to charge the battery.

  20. Views mean a substantial portion of the video has been watched and takes time to happen. A like registers immediately when you press the button. Why is this exceptionally simple thing so hard for some people to understand??? This is why I won't let anybody else repair my things.

  21.  @milojkokitic6991  Since YouTube notified me of your comment I'll give you an answer even though it was addressed to the original poster just in case they don't respond. The short answer is that you have nothing to worry about and you can rest easy without concern about the number of times you turn your speakers off. The chip affected in this Lenovo issue is a serial Flash chip which is made for storing firmware and configuration data that almost never changes. They have durability as low as 10,000 writes per page and retention of ~20 years but they have very high density and are very cheap per byte. A driver with a bug that writes once per minute will hit 10,000 writes in 7 days. A better chip with 100,000 write durability will be compromised in 70 days when writing once per minute so you can see the problem here is that the damage is from an automatic process. Your speakers almost certainly use EEPROM rather than Flash. Durability of EEPROM is commonly 1 million writes or higher and retention times of 100 years is common because they use larger structures on the chip, but the storage density is much lower and the cost per byte of storage is huge compared to Flash. EEPROM uses similar technology but it's byte or row oriented rather than page oriented which is much better for configuration data. If you turn your speakers off 100 times a day, you'll hit that 1 million write limit in 27 years but the switch will fail long before that. Nothing to worry about.

  25.  @ShyamadeepPrasad  I became an Apple authorized service technician before Louis started Kindergarten and I've done board level on Macs, PCs, proprietary systems, and even a NeXT cube. I started in the mid 80s. Mr.D L is speaking the truth and you sound like a typical hateboi. Apple turned into a shit company about 1983 but they've made lots of great products that outlast most PC products. I'm using an A1398 Macbook right now that's been exceptionally solid. Since I bought this machine I've had three PC laptops die on me, a Dell, a Lenovo, and a Toshiba, and I've also had two desktop PCs die on me. Did you know that Mac PostScript drives deliver more font "hinting" data to printers and imagesetters and therefore Macs will ALWAYS produce better looking output? Ever heard the advertising line "Got Milk?" I installed the Macs that campaign was created on. Professionals use Macs for a reason and if you don't understand that, it shows you don't have the requisite professional experience or knowledge to understand.

Have a look at the plans floating about on the Net and one simple but more useful design to look at the is Eddy Bergman's "Simple but effective Transistor Curve Tracer circuit". Cheers.

  36. The purpose of R3109 isn't to communicate with something that's not there... it to make sure the test logic knows that nothing is trying to talk to it. I've seen noise do all kinds of stuff on I2C busses missing both the pulls, but you're probably safe if at least one pull-up is present.

  38. Asbestos was a very common building material in New York in the past. You find it in everything from floor tiles to cement to insulation. Luckily his lease stipulated the landlord would take take of the testing which came out clear, but Louis did additional testing as well.

  39. LMAO!!!! All that whining about Macs and here's the supposedly "better" machine literally KILLING ITSELF BY DESIGN. 🤦‍♀️

  40.  @GlenwingThink  Wrong. Kills itself by design is more like it. When a memory chip fails because its write capability has been exceeded by the design and that requires a board swap repair from the maker, that counts as a physical failure of the product, turning it into junk. All my data is accessed through Thunderbolt on an external RAID so the port's physical failure means the machine is now useless. Does Apple which is admittedly a vile company get the same latitude from Louis when a 3rd party component stops working? No, he rails against Apple. Do Apple implementations of the Thunderbolt firmware/driver have this same issue that kills motherboards? No. Hypocrisy is hypocrisy is hypocrisy.

  41.  @GlenwingThink  What I said wrong to was your assessment that this is simply "a port stops working due to a bug from a third party company". At that point, to me it's a brick and thus for my work it's "dead" and aren't many failures because of a bug, manufacturing or otherwise, from a 3rd party company? We don't know what hand Lenovo may or may not have in this and we never will unless this turns into a class action lawsuit and even then probably not. I don't know which controller this issue relates to but I used to design Thunderbolt products for a major Mac peripheral company so I do know the larger vendors have the ability to get customized firmware through official channels (every last detail in Thunderbolt design is reviewed and official) and the Apple fork apparently didn't suffer from this self-destruct issue. Is it internal to the Intel Thunderbolt controller firmware?, is it in the PCIe host driver for the controller?, or is it Lenovo firmware that asks the housekeeping routines in the controller or driver to do the damage? The machine is literally physically killing itself as a function of running normally and when you certify a new driver for distribution you need to test it. Any sharp engineer at Lenovo doing the testing should have noticed the constant write activity on the QSPI Flash on the controller. Those pins were always monitored in my lab because we also tinkered with the contents directly to set IDs and other parameters. We had boards jigged up with headers for the purpose. If Lenovo pushed out that driver without proper lab testing, they have some culpability and it is "by design" even if that's an errant design. The code does what the code was made to do, by definition, unless the hardware is faulty. The code that somebody very poorly designed that made its way through testing is "design" even if it's really bad design. Numerous times I've seen Louis rant about Apple over something that was a similar component failure from a component vendor but it turns into 5 minutes of blah blah hate blah blah apple is shit bla bla bla and I'm saying he's being inconsistent. Apple is an evil, shitty company. I think we can all agree there, but when the issue is an Amphenol brand connector failing and "Apple screen fuse" becomes a meme here, people are not following the path laid out by the evidence or reality.

  43. 20 years ago I had a consulting client with horses who got that stuff (glucosamine and chondroitin) from his vet labeled for equestrian use. He and his girlfriend were taking it daily with great results (they were in the 70s). The only thing is that you can't stop taking it or things degenerate right back to where they were.

  45.  @shaunclarke94  How would he know? Is he part of the design team operating under non-disclosure? No. The release from Lenovo doesn't lay blame, it only names the NVM subsystem in use and says that a new package with version 43 should stop future damage. No root cause is cited. Ask yourself why this didn't affect machines from HP, ASUS, Dell, MSI, or Apple. Ask yourself why only 30+ Lenovo models are affected here and no other machines. Ask yourself why the driver in question is marked as being provided by Lenovo and not Intel. This was more than an oversight because lenovo pushed the driver out and didn't test. I used to design Thunderbolt devices and the testing involved is beyond comprehensive. There's no reason continuous writes to the SPI Flash shouldn't have been noticed in testing; that's what testing if for. That's why testing is done. And come on... this bug has damaged what probably totals millions of machines. Why are you attempting to shift blame from Lenovo where the partial evidence we do have is pointing, to Intel where you don't have any evidence of fault whatsoever? Do you have any evidence? Please prove me wrong.

  50. I used to work in a shop that repaired ThinkPads and MacBooks as well as other PCs. We had clients like PG&E, Bank of America, United Airlines, and Genentech. All our accounting and business information was only trusted to the Macs and a backend UNIX database server, never to a Windows box as the data was too valuable.
