Heheheh, yea... It's most likely EMI filtering for group-loop inductance - stops the ground plane forming an antenna that transmits switching noise on the power rails and potentially interfering with other radio equipment. The bulk decoupling in those Poly-Tantalum caps is the real stability for that chip. So yea, definitely not critical, but if you're doing board repair, you definitely want a pack of 10uF 0604 caps on hand, one of the most common ones to die.
Excellent!! See that's what I'm talking about re content. I will NEVER be an Apple owner and certainly never try to repair one BUT BUT BUT the diagnosis, explanation and demonstrated techniques are fascinating to watch. Well done 👍
Done watching, thank you very much for the informative repair video. I have learned significantly more troubleshooting & repair lessons in this tutorial video and to your other repair videos as well compared to my ENTIRE 4 YEARS OF COLLEGE EDUCATION. I hope you will soon have a mini-series for Schematic & Boardview-free Voltage/Power Rail Tracing[12V/18-20V Main Voltage Rail, 5V, 3.3V, CPU/GPU Core Voltage Rail, DRAM Voltage Rail, IGPU Voltage Rail, System Agent/Northbridge Voltage Rail, PCH Voltage Rail, BIOS Voltage Rail, Battery Power Rail], Proper method of testing/checking of potentially faulty MOSFETs & ICs/Controller Chips, CPU/GPU/PCH Reballing and BIOS Bin File Editing.
Good spotting on the external board in the schematic. Now and then we do get the donor boards, which do have their own 820-xxxx codes as well. Nice repair, and yes, definitely still worth repairing those daughter boards. Microscope video colouring looks great. btw, the USB-C meter if you get a USB-C => Magsafe2 cable you can watch the current demand graph on the PC for OBS recording too.
@@Adamant_IT I've basically stopped using my programmable DC PSU; everything I do is now from the Apple 85W USB-C brick and then a selection of the USB-C => * cables. It's much easier now. The PSU still gets used but it's mostly for truly obscure jobs or POWAHHH INJECTION :D
I have to say massive KUDOS to you Graham... having run a customer support team for financial markets putting the customer first can never be wrong... GREAT service (y)
After hearing about your RUclips algorithm-related woes on the Saturday stream, I think these type of videos will have you roaring back up the charts. This was Northridge Fix quality.
Young Graham: I already have a LFC#367 so I saved it as LFC#369 (in case you want to correct). Thank you very much for sharing. A fraternal greeting from Mexico.
Great video! I work in the tech industry, but not the hardware repair field. However, I have always been fascinated by computer repair. It is for this reason that I have set out to watch at least one of your videos daily. Once again, good job! Also, a quick question: where do you get the board schematics from?
Hi Graham, I've got a Lenovo Flex 5 Chromebook with some faults. Would you be able to have a look at it if I'll send it to you, please? Main issue is the very often black screen coming up whilst power is on or working on it.
Hi Adam, love your videos Could you please share a video for lenovo laptop with error message ac adapter connected but not charging. Its a motherboard issue Or How to make lenovo T480 laptops to discharge removable batttery first then discharge the internal one. I dont know whether its bios, firmware, driver, application, window or registry issue Regards
Hello 👋. I have an Asus laptop, model k555l with x555ld REV .3.6 main board. I had connected my laptop's cooling pad using a 9-volt and half-ampere adapter, but I wasn't paying attention and the cooling pad was also simultaneously connected to the laptop via the USB port. Now my laptop turns on, but the laptop screen shows no sign of being on. In your opinion, which part has been damaged by this simultaneous connection of the cooling pad adapter and the connection of the cooling pad via USB to the laptop?
Worth it if the pads look grotty / damaged. But in this case they looked pretty good after the tooth-brush clean, so I was able to just slap the new capacitor in.
Both cameras are Insta360 Link. Not cheap, but the best webcams I've used to date (and there's been quite a few over the course of the channel) Amazon Associate link: amzn.to/45YeaaN
I guess you can't charge for a board repair given that a replacement part was so cheap/easy? Also I feel cheated out of the cleaning of that screen.....lol
Common issue on old MacBook Pro Retina screens. It is possible to scrub off the damaged anti-glare with cleaning kits, which will give you a clear display again. It's not so bad IRL though, the studio lights and camera make it look extremely awful in this video.
@@Adamant_IT Thanks for your answer. I saw the screen and immediately remembered a similar 32-inch Atvio TV screen that arrived at the shop. Using glass cleaner and scrubbing with a plastic putty knife didn't work. We were looking for a new spare part (Taiwan) that was cheap but they had the condition of ordering a minimum of 10 units (I thought they were crazy). The client told us that he tried to clean it with a cloth moistened with water (as recommended in the user manual), given his sincerity I did not want to charge him for the diagnosis, I called the technician who did the work and then the client paid him with his own hand . .if everyone were like him
Nicely done Graham.
1 more piece of e-waste averted! Nicely done
"Well, that capacitor is not super important. It's just stability", the captain said to the passengers ... Excellent video again Graham, thanks!

Cracking job, Graham. I'm sure your customer was most pleased.

I need to get one! I've got the software for your USB-C meter now and it's a lot slicker than my bench PSU, so would be preferable!

A very nice quick fix.
Great video as always, a 10p capacitor can take down a £1000 laptop.
I have to say massive KUDOS to you Graham... having run a customer support team for financial markets putting the customer first can never be wrong... GREAT service (y)
the screen on that macbook looked filthy
This gen had issues with the anti reflective coating
Great work
thank you big boss

Ah, well spotted, fixed!
Excellent Job.....
Well diagnosed Graham 😀
Nice easy fix and plus those SMD resistors are super cheap!
I really liked this repair. Can you share a link for your multi meter probes? I am looking for recommended ones.
lovely - but where did you get the apple documentation from?

That display looks a bit sickly
A set of soldering hot tweezers would have been handy !

In your opinion, which part has been damaged by this simultaneous connection of the cooling pad adapter and the connection of the cooling pad via USB to the laptop?
Out of curiosity, why didn't you clean the pads with leaded solder?
Worth it if the pads look grotty / damaged. But in this case they looked pretty good after the tooth-brush clean, so I was able to just slap the new capacitor in.
he, was wondering what you charge to replace thumb sticks (stick drift) on a series x controller? thank you.
"rapid cooling" 🤣😂🤣
please tell me that which camera use over the head....
Guide me

Nice video,bye the way,what name is the Keyboard in the beginning of the video?
It's a Royal Kludge RK100
Hi what part of London are you based ?
I guess you can't charge for a board repair given that a replacement part was so cheap/easy?
Also I feel cheated out of the cleaning of that screen.....lol
Time wasted on replacing that cap. It's fiiiiine.
Someone licked the screen...
That screen though....
Is it my eyes or does that display appear trashed?
That is a common issue known as "staingate".
wtf is that screen!? It looks disgusting
