- We are seeing more and more MacBooks were dead because of blown USB-C Controller CD3217, as it does affected by several factors explained in this video, and also why the repair will be quite expensive.
Note: Before you asked did we changed the small IC ROM for CD3217, yes we did and nothing changed. Secondly, it doesn't matter between Small Dot CD3217 vs Large Dot CD3217. You just need the right preprogrammed parts.

damn man, these are 2-3-4k $ devices and they wanna save 1 or 2$
Designed by an American company.
Indeed, Apple saves millions of dollars on cheaper components and ensures future failure of the device, so you buy a new one. Lawsuits and warranty repairs are already paid for many times over by the cheaper component savings.
@@FVBmovies depends on the product, use case, and scenario actually. everything ive owned was a dream to use. cant say the same for other people but just my uses.
That's not even $1. LTC is known to give MASSIVE discount to big customers. Most major brands will do the same, they offer products at mot that much higher than bare cost for their big customers.
Take the LTC chip as an example, the die size can't be more than a few sq mm, and for mass production of mature analog processes (say 350nm), per sq mm cost can't be more than $0.08. So, the chip costs at most maybe $0.4 to manufacture. If Apple is negotiating the price, I'd be very surprised if LTC even dared to ask for even 50% gross margin, so at most the chips would be $0.8, and that's a worst case estimation.
Apple is literally saving cents by using a lower rated chip.
Well they’d be 8k devices if they didn’t apply that logic across the BoM
My M1 Mac mini (2020 model) blew two weeks ago. I pulled the board and saw a suspicious raised dot on one of the chips and figured that was the problem. Now thanks to the video I went and took a closeup look at it: a CD3218 B12. So not the 3217, but close enough I'm guessing it does the same job and failed for the same reason (plugging in a USB cable and bye-bye logic board!).
god bless you and the work you are doing! as a repair shop owner I can finally use the light bulb analogy to explain it to the client and why the repar will cost so much
Getting to the point with Apple that you have to create a video and say. 'If you want to fix your Apple product you have to watch this 5 min video' so that you don't have to repeat yourself to every customer. Before saying what the price is.
Engineers that prototyped this IC must be sued for real
Not the Engineers, the one forcing the low budget should. In this case apple
@@otozinclus3593 if the cheaper chip works well, then why not to use it?
But the IC die has some design flaws that may or may not occur, so it didn't have any reliability tests.
Apple probably didn't expect that chip to fail and made a reasonable cost cut.
@@Gameplayer55055 But that is the point: The cost savings sacrifice quality and decreased quality increases the likelihood of fails. It is a calculated gamble
Apple does this with all kind of their products, as an example the MacBook air M1/M2 base model SSD dies extremely quickly, because of the limited 8GB RAM making the laptop use Swap a lot, as well as the cheap SSD they used in the first place. But there are dozens of examples
Apple skimps on quality very regularly and sometimes that leads to failure. But Apple does not care, because they will frame it like it is your own fault
That's apple's fault. Chip has clearly stated specs, which apple clearly doesn't follow.
@@Antagon666
10 amps for 2 ports
But 6 amps for 1 port
Seems logical, but something went wrong
why apple engineers still using this f%ing ic TPS62180 ?
Because they have smol brain
not because of the engineers but because of the greedy MBAs in-charge
It could be that they don’t understand the failure mode. Clearly the buck mosfet is failing short and passing 12V, but that could be just one possible failure mode.
This video mistakes failure rate per operating hour (by recommending that you unplug all usb) vs the failure being instigated from an esd event, a bad high voltage handshake, or some other discrete “event”. In reality, it’s clear the author doesn’t know what causes the problem.
@@trshcln6937Because they have SMD brain lmao
My cheap HP gaming laptop simply cuts the power off, lmfao.
You can have usb-c ports, ofcourse. You just shouldn't use them. On a serious note, the 10A 5V chip will probably get burned as well if you use both ports at the same time. You could try testing small heatsinks on the 2 ICs (lower the temperature, increase its lifespan).
Just my anecdote, I keep two Dell monitors each connected to my Macbook M1 Pro via the two left USB-C supplying both power and display. They are connected 24/7 except the odd day or two each month where it’s disconnected for travel. It’s been over 2 years I’ve run it like this and haven’t had any problems yet.
Come back when you have an issue
Bro you’re really testing your luck here 😂
It’s a usb C cable just remove it
@@jjptech Yeah that's the plan if I remember to come back and update this comment in the future. But again even if it does die it's only one anecdote and shouldn't be biased and focused on this one experience.
@@legend-2890 It's for my business and it's got applecare+ on it. I hate how half the time after bringing it back up from sleep overnight it forgets all the window and app positions especially since I use multiple Spaces for each monitor. If I unplug it every night, it just never remembers any of it and I spend time every day moving all my apps back to their correct monitor and spaces view. Plus, if people are going to nitpick about their mac's life, right now its behaviour is set to keep the battery charged to 80% only to keep the battery healthy, if I keep unplugging it every night it'll remember to fully charge to 100% by night time when I don't actually need it.
Man I do these to with my dell monitors. Scared af since seeing this video
I'll keep an eye on mine. I have a 2023 M2 Pro 14" model so its definitely got one of these suckers. I'm quite confident about replacing it if anything bad happens, but id rather not. I use it at work plugged into a USB-C dock all day, so that's slightly concerning. But at the same time, I didn't pay for it, nor will I be paying for the repair.
You might want to leave it open, and close it only when you must. Mine is from may '22 and it only lasted about 2 years and 1 month, opening it a couple of times a day on average, got me the flexgate problem (broken display cable, which is, of course, soldered to the display, $800 to fix :) Other than that, they are great products with nice finish - they explode 😂
If I leave the macbook conected to an hube that also provide power for a lot of time it can also make damage?
does this mean the regular m1/m2/m3 macs namely macbook air is unaffected by this?
Seems this could be a software fix, hopefully they will push some to fix it. But it also seems this might turn into a class action law suite considering the cost of these macbooks. With this being such a long term issue you can’t tell me apple isn’t aware of this by now. I’m sure they know.
This is the kind of issue, you would expect from a device with 1/10th of the price. Within 20 years of non apple and much cheaper devices, I've had only 2 VRM failures, first one was because of shorted ceramic cap (I caused it by spinning a fan in opposite direction with vacuum cleaner), easily fixed by removing the said cap. And the second one was caused when I shorted Vcore of RTX 2060 when soldering extra capacitors, again easily solved by removing the short, and replacing a 12V fuse.
So all in all, nothing has ever failed for me, unless I caused it directly by myself.
What about display monitors connected via USB C? Does the same scenario apply?
I think there is more involved when it comes to replacing the cd3217. You would according to say have a master and slave cd3217. If you replace the master then you also have to replace the rom chip of that. At least I read this somewhere
this 👍. you're right, the chip revision also matters( you can discern it by the markings and type glossy/mat).
since all the chips are not the same revision, swapping them will cause issues with the program inside the rom.Keep in mind the code inside the rom defines what functions are used: usb3/2, pci passthrough,dp port......) so naturally it will not be the same between all models.
replacing both is good practice, when you pull from the same board.
We did the ROM swap, nothing changed. And every other CD3217 sources you can imagine (not shown in table) but it still didn't work. Read the blog and you will understand
@@iBoffRCC In any case, a lot is still unclear when it comes to the cd3217. Hopefully there will be solutions to this problem. For example, it would also be nice to be able to disable a cd3217 and case of (for example) water damage.
Are the 2 left USB C Ports generally safer to use?
@iBoffRCC could you please elaborate a bit more on the different usage of these usb-c ports ?
More importantly, is connecting a thunderbolt or usb-c screen, and therefore also charging/powering the MacBook via this port could have the same devastating effect on the ports' ics as connecting a peripheral that needs to be powered by this port ?
This is not very clear from your video.
What if I just plug in my usbc devices only on the MagSafe side? I have a M2 Pro 16inch MacBook, I usually have only 1 thunderbolt cable plugged from my dock that does everything from display/power/peripherals
wondering the same thing
I saw a video somewhere else Lenovos had a similar issue with their thunderbolt ports
it looks like it's best to use the MagSafe side because the LT8642EV-1 10Amps is in charged of that side. Also, my Lenovo Legion USB-C port died and killed my nVIDIA GPU. so this problem isn't just Apple's issue.
@@evanmila4048 yea I knew someone where I saw Lenovo used the same ic chips too seems like a intel controller issue
this channel is a live encyclopedia. well done!
is this an issue on mac mini as well?
As a M1 Pro macbook owner for 2 1/4 years, I'm now scared. Is this only happening to 16 inch or also to 14 inch MacBooks?
My entry level Windows Laptops, which does have USB C, doesn't have this issue
While the USB C only does regular USB as usual
Hey this thing just happened to my M1 Pro 14-inch. Wasn't using it for a week, was left disconnected. When I tried to turn it on, it was dead. It was working fine when last used. When I checked the board, it was completely dead. There was a hole in the CD3217. I wasn't using the right USB-C port at all since I saw this video 2-3 months ago. So apparently it can happen even without use.
It is my daily driver laptop for multimedia stuff, and I had some data on it... it failed just after 1 year of moderate use
Is the left side ports more reliable?
Is this the same for the desktop models?
so what is says, is that cd3217 can be only replaced from the donor boards from the same place ??? it is sucks
As always, a very complete video. Keep going, folks!
Thank you!
Does the TPS62180 chip also supply the 5 volts (and degrade) when connected to a USB-C dock which gets its power from an external PSU?
Once again, iBoff comes through with a masterful video. Turn your notebook off once in a while.
Thank you for this amazing video.
Some questions: is this faulty chip also present on iMac / Apple displays?
Does this also happen if what's connected has it's own power supply or if it's powering the laptop?
Is this issue also on the Mac Mini and iMac?
does it only affect type c ports?
for example if i kept a sdcard in slot would i be fine or an hdmi cable and magsafe?
same questio
So just shutting it down instead of leaving it to sleep should "prevent" this issue?
Hello brother, thanks for the awesome video.
I have a question, I have M3 Pro Macbook Pro . Is it safe to leave USB-C extension cable (Male - female) always connected, and disconnect the USB device from the female side when not in use. I don't want to damage my port by removing and inserting multiple times a day.
Thankyou
It’s only bus-powered devices that are the problem (drives & hubs), right? I’d think that displays would be ok since they’re not drawing power from the Mac. Likewise, running the Macbook from a powered dock ought to be ok as well, I’d think. (?)
I am wondering the same thing…
I guess im not using the usb-c port on the right side of my mbp M1 16" anymore. Thanks for the info and for the very detailed description of the problem and the solution to it! You make repairing stuff actually fun, and on the other hand its a big fu*k you to those big companies who would just say that those devices are broken and tell u to buy a new one. Thank you alot!
I wonder if it is safe to plug in SD cards for long periods of time, does it also use the stepped down voltage from that sacred buck converter? SD should be 3.3V so I assume no?
Does A2141 also uses TPS62180 to power USB ports? Left side, right side or both?
I think when it's sleeping and you plug something in macbook darkwakes and then sleeps again after some time with usb-c unpowered.
We'll check that. How long would it take to go unpowered?
@@iBoffRCC idk for sure, it's probably depending on settings. What I do is connect my phone when MBP is sleeping, phone starts charging. Then after some time (about a minute in my case, but I have very short sleep times in Settings also) charging stops. So I presume in real sleep external ports are not powered.
Also if you run
pmset -g log|grep -e " Sleep " -e " Wake " -e " DarkWake "
in Terminal, you will see a "USB-C plug" DarkWake for 45 seconds (in my case) and then Sleep
DarkWake from Deep Idle [CDNP] : due to SMC.OutboxNotEmpty smc.70070000 smc.70200000 USB-C_plug/ Using AC (Charge:68%) 45 secs
Entering Sleep state due to 'Maintenance Sleep':TCPKeepAlive=disabled Using AC (Charge:68%) 26 secs
DarkWakes are service wake ups with screen off.
Apple why make life so hard …it should be easy to repair these devices man. These laptops are very expensive. Unbelievable 🤦🏻♂️
Already happened to me, during peak loads on all ports my right port just died and only started working again after a full reboot. Btw your animations are top tier, thank yu
"only started working again after a full reboot." if it started working again, then it didn't have the same problem as described here
This issue isn’t something that can be fixed with a simple reboot. Your issue is different, these chips are fried and have no hope of recovering
to prevent this from happening, can I just use the left USBs instead of the right one?
Thanks for the informative video! What about active docking stations that charge the Macbook? Does this also place a load on the TPS62180YZFR?
I love this guy's humor.
I first said to my SO, do you smell something burning? Then quickly unplugged it. Luckily quick enough that it only damaged that port. It isn't that bad living with just two USB-C ports
Does this means keep magsafe plug in is also prone to failure?
Thx for telling us. This can save us many many hundreds of dollars. I haven't been using this port very often, but now I won't be using it in the future. I have a MacBook Pro M2 and I love this device, but its still prone to fail.
Too bad the IC cannot be programmed, or I guess it could be programmed, but the proper ROM is most likely impossible to obtain from anywhere.
The same thing is with SMC on older boards, as the SMC was programmed with Apple's custom firmware and you had to took it off the exact same board otherwise it didn't work.
Does this affect Mac Minis bro? I leave my hub in all the time... yikes
Do I understand correctly, that this is only happening on the right side? I currently use the right port with a dock but I could switch to the left side. I always unplug in standby, as I don’t want my battery to die and in general I never leave devices plugged in when not in use. I only sometimes leave an ssd plugged in, usually in the left side. Will stop doing that for sure.
amazing video with tons of info thank you for your help!!!
So basically as long as you don't exceed 30w on the right side port(6a x 5v) you should be fine?
Does this TPS62180 problem not affect the macbook airs (regular M1, M2, M3, not pro not max)?
hello, I was wondering what would happen if i let an externally powered device plugged in for a long time, this shouldn't happen right? the IC wouldn't need to deliver the current and the problem would not be applicable, right?
love this editing keep the good work up
Apple should be sued for this--selling expensive defective products.
Any chance you know if Mac Studio uses the same IC?
Absolutely brilliant video! Thanks so much for posting.
But if I keep my USB device plugged in the other ports it will fine right ?
New video. 🍿🥤This is gonna be awesome!
4:15 animations the best 😅
why didnt my macbook aoir 2020 m1 hasn't blew it's thunderbolt type c port after plugging in a type c hub for 2 days no unplugs?
Air M1 doesn't use the TPS62180 so it simply couldn't have happened.
Does this apply to imac m1 and m3 too?
just replace this cheaper TPS with expensive one.
Always excited to see your uploads
From my experience in many cases TPS dies from charging external devices and cheap hubs. Basically same reason caused famous "GAY chip" problem
.
Cd3217 programming difference is i2c address written to OTP. There is also differences in configuration depending on TBT chipset used. Such chips can be bought in cd3217 sets, approx 70$ per set for all 4 chips marked with their positions by many ic sellers on China.
Also in many cases removing 5v will fix the device since 3217 usually is ust partially damaged, I mean, logical part works ant it is still visible on i2c rail.
Hey man, if my mac is connected to a powered TB3 dock, is it safe from this problem? I understand with the TB3 dock all the devices are powered by the dock, and it also supplies power to mac via thunderbolt. Thank you for your insights.
@@michesbianan well if dock pro actively uses external power supply that would be safe. You can buy a keweisi 1802c USBC power meter like to know for sure, that's really useful thing and it will show you if your dock sucks power from usbC or not. Otherwise use left side, closest port to the magsafe, this one is not hard to replace since it's not preprogrammed.
@@inwerp Thanks a lot for your insights man. Yes, it uses an external power and I have the TB3 cable plugged at left side.
How about m1 macbook are, are they prone to this fail?! Thanks
I use my macbook in clamshell mode nearly 24/7 with magsafe, monitor to usb c, and ethernet to another usb c. Guess I'm fucked huh?
Only time will tell. Always make backup data on external drive.
What about docking station?
It's called built-in obselescence, it is best to stick with old technology as long as possible.
BRO the hot chip at the end due to leaving USB SSD attached due to overpriced storage.
Is this also valid for m2 mac mini?
Are these timebomb ports safe for charging only (with official psu & cable)?
Or am I now limited to using the 2 left ports?
2019 16” mbp
😮
Is that an issue with m1 airs?
3:26 this is the peak
Oh Apple the incarnation of corporate greed.
Hardware fuses. Typical of Apple planting hardware fuses to go off at a specified time so to get the consumer to upgrade their machine. - Planned obsolescence. If it don't work on hardware Apple plant software fuses via upgrades to slow down processors, fail the component that was meant to fail but didn't etc. It is all about grabbing your reliable machine to get you spending again.
Every problem that apple has is a honey on my heart ❤
Bro thank you for the video
Excellent content
gracias exelente explicacion.
Yea but i have a headless macbook pro 2016 as a server and some ethernet interfaces and hdd connected 24/7
_"We are aware of a _*_small_*_ quantity of incidents regading this piece"_
- Apple site
If you look at the biggest shareholders of Apple they are all large bankers. They have forced Apple to use poor quality components that will fail. My old MacBook from 2015 is still working. The new MacBooks have a life of about 5 years.
Video too graphic for me. As an electrical engineer, it was hard for me to watch. The video tries to much to appeal for wide audience, but fails to capture the more technical ones. Nice that you mention Rossman, who is a great example of "no bullshit" youtuber.
Nein- nie Probleme
Just wow Apple now locking chips to work for a specific model only on specific spot on motherboard. 🤬
Laughs in Applecare
oh shit i have one of these
I feel like I really need to start exploring android / windows ecosystem. or just never ever let Apple care lapse.
I mean WTF Apple you greedy 🤬
Naw man. SO basically don't use your mac the way you use your mac. I'm not unplugging my usb hub that connects my monitor and external hard drives which power my home media server. If you unplug the display the computer turns off / sleeps. So yeah. always on 24/7 if it's an apple problem applecare will cover a replacement but not changing my behavior on the off chance that it fails. thats on apple.
Just don't use apple.
my next laptop will be from framework
Which Macbook Pro models would you recommend to people who love explosions, please? I am from Afganistan and perhaps I could convince my boss to have us wear macbooks instead of wearable gren'ades 🤣😇
people: why does apple use this part even after knowing the drawbacks 🤦🏽♂️
me: why does people use this apple products even after knowing the drawbacks 🤦🏽♂️
thanks, now i will be careful to avoid using the right USB port as much as possible.
Thanks to Apple 🍎 , to make Life more colorfull 😂
These videos are great lol
Now i found the reason why my sister only buys intel windows laptops and not IOS macbook.
wait, so apple is making $10 as using cheaper parts and ruining our thousand dollards machine? Short the stock lol
“planned obsolescence”
