NAND ic chip damaged in Macbook Pro 16 inch, 2019 model

I purchased Macbook Pro 16 inch, 2019 version in November 2020. It is just 2.5 years and my MAC suddenly refused to start. Apple service center told me that the NAND ic chip is burnt. And the whole motherboard along with the touchbar needs to be changed. I bought the MAC 1,85,000 and in just 2.5 years, the replacement cost is 65,000. There is no physical or accidental damage from my end. This is so unfair!

MacBook Pro 16″, 13.3

I took my MacBook Pro 16, year 2019, to a repair shop and the following was told to me:


During the measurements at the repair shop, it was possible to identify a region of the board heating up a lot, to the point of burning the technician's fingers when touching the area.


The component in question was the NAND, one of the data storage units on the logic board.


The NANDs are powered by some voltages, among them a voltage of 2.5 Volts. The circuit that creates this 2.5 Volts voltage, in turn, is powered by a voltage of 13 Volts.


The problem with the client's logic board is exactly this circuit that receives 13 Volts and, from there, creates 2.5 Volts.


Unfortunately, it is commonly observed in specialized Apple equipment repair shops that, when this circuit fails, it ends up creating a path for these 13 Volts that feed it to reach directly the NANDs, where the client's data, operating system, and other things are stored.


It was because part of these 13 Volts reached the NANDs that they died and are heating up in this way. The 820-01700 board often arrives at the repair shop with this flaw, and this equipment was no exception.

this is a common problem with t2 MacBooks because apple chose to put the efi aka the bios data to the nand flash instead of a separate chip like everyone else on older Macs with the separate chip it would show a blinking folder *** with a question mark but when the you plug in an external ssd or a hdd it would boot from it but since the bios code required by the computer to boot is missing because of a failed nand flash you can't do that with the t2 and all m processor Macs this can be fixed with a nand replacement but apple dosen't do component level repair on and besides when a failure like you have mentioned happens it usually shorts the nand to ground and then brakes all sorts of component level problems a well knowledged 3rd party can do those reapers but since apple and apples partners chip manufacturers dose't sell those chips and ICs the repair is often costly because those components have to come from another Mac that has a bigger failure that makes it too expensive to repair for example a cpu failure or a gpu failure or in. many cases there are macboock board that have been smashed because in some state laws require full removal of all data with software that costs too much fore a recycler so they end up smashing the boards in those Macs and selling them as parts and since the new MacBook pros a getting thicker they can maybe put a m.2 ssd and use a separate bios or make the bios data restorable with dfu mode witch you can do with the Mac Studio so that recyclers won't have to destroy perfectly good boards and these repairs can be done by anyone and it would be way cheaper even at apple stores

Macbook pro 2019 model is most worst laptop in my experience..

I also purchased a 2019 16” MacBook Pro and it too suffered a catastrophic failure with NAND ic chip. Twice! I paid over 6k USD in Hong Kong for this 8TB machine and it failed 3 months after I purchased it. The first time it happened, Apple did replace the logic board but I still lost significant data.

Well, it happened again. Just before Christmas, it wouldn’t turn on. Initially, apple refused to help but after I complained, they agreed to very small reimbursement toward a repair. I sent the machine to OnTrack data retrieval who replied that the data is irretrievable.

Given that I have been a loyal apple customer for 20 years, have spent tens of thousand of dollars on apple products in that time, I have to say I am more than disappointed. Apple’s quality is clearly on the decline. This isn’t an isolated incident either; it is a known design flaw that apple should take responsibility for regardless of whether or not a customer has apple care. Apple care is meant to address accidental damage and isolated product issues NOT a faulty product line. Apple should offer a full reimbursement or at the very least a new machine! For a billion dollar company with a loyal customer base this is pretty abhorrent customer service. Shame on you Apple - Using Apple Care to avoid taking responsibility for a poor product line.

About AppleCare+:

AppleCare+ would cover damage that is not your fault. So, next time you go about purchasing a Mac, consider getting AppleCare+ with it. I sent my 2017 MacBook Pro in 11 times due to a loose screen-to-LogicBoard connector. I was given a free 2,500 upgrade, being I want so kind and patient of a customer. All they charged me for is the AppleCare+. Go Here: AppleCare Products - Mac - Apple

Here's how you get back at them:


When you know the cost of failure is going to be very large:

You buy their relatively inexpensive AppleCare PLUS package. Then when that complex battery-capable portable computer fails, as you KNOW it will, APPLE has to pay for the bulk of the costs to repair, not you!


...And to avoid losing any data, you buy an external drive and use the FREE Time machine software they included, to make backup copies of all your files with Time Machine. Then when that data disappears, you can restore it later! No data loss!


That will completely out-wit them!

note: this can and if you use your device a lot will happen in the lifecycle of the device SSDs and HDDs are ware parts just like batteries that's why it's important to have them replaceable not only to make it cheaper but also greener keep in mind the carbon footprint of a device isn't only it's manufacturing but also it's end of life and maintenance if you can get away with replacing a single nand module or a m.2 SSD it's way batter then replacing the whole board or even the whole computer in some cases

Consumer products, their warranties, and their extended warranties work in a predictable way.

 

Warrant-able implies, but does not guarantee, High Quality:

Consumer product makers build high quality products. You can tell because the manufacturer is willing to stand by their products and repair or replace them (but only for defects in materials or workmanship) at manufacturers expense for a stated warranty period.

 

For Apple Macs in most countries, that period is one year. That is the total responsibility Apple or any manufacturer has to you under law. Assumptions about additional responsibility of Apple or any other consumer product-maker's products working longer than the warranty period are not accurate. The amount you paid for the product has no bearing on this. The rules are the same for a car costing US$20,000 or more.


Other than Apple, Inc. the only authority that can declare an entire product "defective" is a court of competent jurisdiction. To the best of my knowledge that has not occurred.


Instead, consumer reports magazine reports that after surveying their members about reliability, year after year, Apple computer rate higher than any other computer maker by a wide margin.

If you made the decision to NOT pay for the extended warranty, you made a decision to bear the cost of repairs during the extended warranty period yourself.


When facing a problem later, the correct cost calculation is:

Example Total retail cost of repair: US$800

less Example amount you saved US$380

by NOT purchasing a service agreement


Effective incremental cost: US$420

PLUS the amount you saved by not buying the Service contract, which now must be spent as well.

Based on Personal Experience:


AppleCare+

Well it’s a 5 grand computer, getting the 2.5 grand upgrade. You’d be surprised how many times I sent my 2017 that I am swapped it out for. Apple told be I spend more than 100 hours troubleshooting it over the phone (how crazy is that)?! It was in during the days of Covid due to screen issues.


My replaced Mac now on an annual AppleCare contract for $99.99USD/year(don’t know why Apple did that), meaning I can renew it for as long as I want (I’m probably paying a grand in coffee a year).


Thing is, it has an Intel processor on it —so I need to run things that I can’t run on my newer M1 Mac with a Silicon chip (as of this reply).


If any recent issues with my newer M1 Mac, it’s software incompatibility, and a one time screen replacement (all for no cost).

<< We should also back up every second because failure is imminent. >>


Time machine backs up changed files automatically, at low priority in the background, without interrupting your important work. Its default setting is about hourly.


When problems occur, your Time Machine backup is the one that is most likely to be there, because you did not put it off making backups, it just took care of backing up for you.

That’s a great idea! Here’s another: you can use sarcasm to mask your role as an paid ‘level 10’ apple employee to shut down any criticism of apple or apple products. If that doesn’t work, you can spend an extra $500 to blindly support a faulty product line from a billion dollar company that refuses to take responsibility for a poorly designed piece of technology that has repeatedly failed. You’re right, I mean, why should we trust a tool to do its job? We should also back up every second because failure is imminent. Most helpful, thank-you.

This is a user to user technical help community. Apple is not here. There are no "paid" contributors here.

Backing up one's data is computing 101 and has been standard operating procedure for computer owners for decades. Your data is no one's responsibility but yours.

The point is that the 2019 16” MacBook Pro is a faulty product line which Apple should take responsibility for. Apple Care is intended to safeguard against accidental damaged and isolated product malfunction. As a desktop replacement, a laptop should function as intended, not repeatedly burn to a crisp. My failure to back up data is indeed my own responsibility. The proper functioning of the machine is Apple’s.

Thank you for the followup reply.


AppleCare:

It's just a recommendation on my part --and it's always been beneficial to me. If you do not have the funds, then next time your get a Mac, get one that is less costly, and that purchasing the AppleCare would equal out to the same price as the one you'd desire.
