Happy Easter to all removed capacitors 😀
Capacitor 😂
Especially to those who have been removed from that special friend. 😂
So rare to see a big manufacturer, specially HP doing swappable components these days. Kudos to their engineers for getting passed the bean counters.
old concept
@@paulsimon1272 That's not the point. The point is in the current timeline all these OEM's are soldering the memory, gpu, cpu etc to the board making it difficult to repair. All of this is swappable.
Rubbish - it's a Workstation from 2017, not a PC.
@@einfelder8262 You don't get it.
@@youtubasoarus Correction. I 100% get it. It's a Workstation from 2017, not a new PC. Get it?
No replaced capacitors. This is the Sorin that we know and love.
Always love to see modular computers.
Happy Easter to everybody 🎉🎉🎉
A1, Happy Easter Sorin and community! Excellent, Thank you❤
I remember when I was younger... and I have a phone next one the computer, I know gone get a call before the phone ring... because the speakers make metallic noise 😅😅... thanks for all, Sorin!!
Yeah, I really remember those short bursts of noise coming out of the speakers just before the phone starts ringing!
i have learned so much from you through years mister sorin, honestly this is the best youtube channel, educational and entertaining, you make electronics appealing to all ages and walks of life, may your cups be full and your enemies few
Happy Easter from Sri Lanka 🇱🇰
The Z2 Mini is part of the HP workstation range of products, this G4 released in 09/2017. So it's old, but it's a workstation, not a PC grade. Up to Xeon E-2286G Processor, graphics cards, and 64Gb Memory (a lot in 2017)
Happy Easter. This one is a Hp z4. Very expensive because is a workstation grade computer. Many option and upgrade because of that
No, it's a Z2 Mini G4, but yes, it's a Workstation not a PC.
Nice fix. I hope they still making a pc like that.
Very nice workstation. I miss the times when both CPU/GPU could be changed on a laptop without using soldering tools.
Some displayport sockets can also take HDMI plug.
Happy Easter Sorin, I hope you found some nice laptop with some chocolate easter eggs in them!
2 more capacitors to replace on the next video... 😁😁😁 Happy Easter Sorin🕊️
The Master strikes again. Great job.
Happy Easter from Germany and get well
This is a proper nice workstation hence the high quality components and design
RF Noise can also be a problem if someone has a Pacemaker for their heart or other medical devices.. also like you said communications devices can be effected... in a older car the radio would sometimes pickup noise from the engine if you didn't use resistor spark plugs in the engine
I put like 470-1000uf 25-35v electrolytic can type capacitor on most of my DC equipment, at the rail input, what those little ones miss the big can types catch
Happy Easter 🎉
Doing repairs today as well. Happy Easter
Happy Easter Sorin , your family and community !🐰
The first second I saw that heat signature I already thought the short is in the other side of the board, Sorin proceeds searching a faulty capacitor 🙈
👍 and a happy day to you to
Im not really electrician but i love to see how you work and the pleasure you getting repearing these devices
Ahhhh i loved it. You had to open youtube to find out how to open it :D So you must felt good and enjoyed it
Спасибо Сорин! Компьютер прикольный. Выздоравливай и не болей!!!
Hi Sorin, Happy Easter if you celebrate and Happy you do what you engoy and love to celebrate... this Is a very nice PC... Thank again for your passion you share with US, bye Francesco Timpano from Florence Italy
I cant believe that it had removable cpu, kudos to HP for making a change.
It's amazing how many people have no idea about how good the HP Corporate Range of Computers are
Thank you , you are the master of electrons i salute you.
Thanks for your information, I appreciate your ability to take on the unknown. and your plane clarity on the subject. And " right the Fixit addiction, i kno.. Seasons greetings
Happy Easter Sorin🔥🔥
Great insight to capacitor functions. What caused the fault to begin with is what I wonder.
GM
Sorin you need to buy A mini dremel ... it's very satisfying to "consume" a bad welded capacitor with this thing :) ( also welded mosfets )
I just saw this on your website: "We Use original components" :D :D hahahha ... I love you dude. Keep it up
There are another function for the capacitors, they provide instant power when requiered. Usually you put one as close as posible to the chip because when the chip requires power the track acts as an inductor and takes time to travel that power. In this case as you Said you have a lot and near.
ok, that what sorin saying. Because of the L and R of the tracks, the capacitors give the power kickly
Happy Easter Sorin! Take some lemon and honey for your cold. Take care!
Good job mate
Well done Sorin
Happy Easter to all too! Sorin, since you are (probably) not a board designer (neither me), you don't understand all reasons for the capacitors. My recommendation: Just put new capacitors in. The designers will byte in their knees if they see that you give customers back boards with missing capacitors.
Happy Easter everybody!!!!
Greetings from 2E0KKV 👍
Happy Easter, Sorin! Another nice video with lessons learned. Just a quick one- wouldn’t low melt solder help in removing the welds? Looking forward to your next videos!
thanks
We need some capacitor eggs to make new ones. Good video.
Proper professional workstation - not a consumer product. With a price to match no doubt ;-)
It's called a busman's holiday, Sorin.
Happy Easter 🦆
Proof that thermal camera is fancy toy but visual inspection is enough.
happy easter sir. God bless
HP put their Maintenance and Service Guides on their website for free which is their name for a Service Manual and that can save you time in removing the motherboard as it shows you how to do it :)
Most people don't have a clue just how good HP is for supplying High Quality Service Manuals and making it really easy to fix their products.
HP also has a Disassembly Video for the Z2 Mini G4 as well ==> th-cam.com/video/4q-Xw3mB8xk/w-d-xo.html
At this post I am very keen to buy such a device. I understand they are made with various configure as to chip set and memory. I am very gad to have an assist as to remove a mother board where I encounter a problem. And, I suspect capacitor fail will be a general fault to the form as build.
As to my work bench, I have a failed device as a 16 track recorder, where a flashing to all contro| (track indicators and power) and 9v power with no fu|| power on. the unit as records voca| and guitar with a dedicated hard drive with a curious reset feature as initia| state post power off required. One other new device, as midi controller with a difficult interface via 2nd bank (press to enter) that will not easily configure or record/playback. The key feature as sequence control and capture/playback. It so happens as brand, very difficult interface to product and end use.
Thank you for the "Easter treat" and the wonderful recap of exactly, why, capacitor placement is a domain as FCC demanded build. Also, I like the solder and flux product as arrived via UK to US mail. (fast delivery) I recommend those products to channel viewers as first rate and good stock to workbench as routine to repair select. Regards from Washington State, US.
I remain an interested student to masterful tech domain as is posted to my enjoyment. M.
Happy Easter Sorin and Diana. From India
Later that day ....
Ring Ring ... Hello, Sorin speaking, how can I help?
Caller ... Hi Sorin, this is Tony from the FCC ......
Happy Easter Sorin from argentina
Happy Easter 🐣
P.S. I enjoy your site.
Thnx.
GM
Such a nice Lesson Master..thank. You for the video!
SAY HALLO TO MY LITTLE FRIEND 😂😂😂😂
Happy Easter :o)
They should also have the capacitors in sockets.
you can find capacitors on sockets in the branded led bulbs and maybe other devices, i have seen them, but only for electrolytic.
Happy Easter Sorin,
Don't you ever get a day off?
Many lives of electronics and computers would be saved if everyone knew this capacitor sceme
"no capacitor, no problem!"
probably Sorin came back already from not feeling well from few days ago 😁✌️
When the customers garage door remote quits working randomly whenever the PC is on and there is a cheap USB mouse attached, they'll never figure it out. I'd recommend replacing the capacitors.
happy Easter Sorin kerala India
You could fast forward the MB removal so there is a video sawing how to remove it. 😅
10:20 listen carefully the sound. I hear like the pins inside the socket being touched. I wonder if they are straight now? xD
cmon Sorin every electrician have all kind od cables from display port to HDMI from vga to dvi vice versa etc... so many ways but you need to have them all idk its maybe just me but its much easier when you know you can test it for sure :) and that converter mini cables are cheap. i purchased in few years all of them now I am good HDMI male to female yes vga to dvi-d yes vga to HDMI yes :D haha idk its little obsession but its nice to have one little box just for that you never know when you gonna need them :) like this situation :) Amazing repair! gg
Alien got birth from that capacitor.
Sorin rules, no capacitor = no shorter capacitor - burned fuse = proper calibrated wire 😂
And no mosfet-no shorted mosfet🤣
Hi, can you tell me how you always find the main power rail so quickly to test for shorts?
Eek. Exposed socket pins give me anxiety. Also, how hard is it to diy a socket replacement? 😢
The computer is expensive only because it's repairable and has upgradable/replaceable modules. Non-upgradable PCs are cheap because the manufacturer knows it can't be easily fixed or upgraded so user has to buy a new one, thus guaranteed income for them. It's similar to how long a TV lasts. If you buy one TV and it lasts 100 years the manufacturer will go broke quickly so they make it last x-amount of time then it dies and you buy another for a cheap price. Same for this PC.... lasts a long time / easily repairable / upgradable so user pays more for it up front because the manufacturer will sell less of them over the lifetime of the product. It's a standard practice that all manufacturers do.
Sorin, it might be a silly question but... I understand that no significant RF will escape the computer enclosure because that metal assembly is acting like a Faraday cage, right? But what about RF energy interfering with Bluetooth and/or wi-fi radios? Is it a concern?
Love peace and happy Easter to all war mongers. Nice repair.
Hp's version of Apple's Studio?
i see framework 16 modular laptop in internet all its parts swappable.. different market strategy to sell.. really good for users but i donnow about producers.
Large value capacitors in those locations are providing a reservoir so that when the CPU or GPU suddenly requests a lot more current it's available. Without them the rail will dip and the PC may crash as a result.
Not even large
feliz Pascoa
Dear bro
Whats the best way to make devices live long
Removing components with pliers risks tearing traces off the board!
It is probably just you, doing it wrong. He is crushing the midle of the component, not pulling the parts from the motherboard. You know, like someone with 30 years of experience...
@@silviuguseila2552 thanks for the tip, but I never did it myself, I just watched people doing it.
The capacitor looks like an alien came out of it.
im not an expert or engineer but those capacitor job is to suppress the noise produced by the switching Mosfet .I build a H bridge for a power tool and i disregard the noise it make at first it work fine but after some use the controller ic that generate the pm signal got destroyed because of the interference of the noise on the main power rail .removing one or tow capacitor from the circuit is not going to make so much difference because the motherboard is over engineer or rather perfectly calculated and one or 2 capacitor is not going to make too much difference but you said in the video it is fine to remove all of those capacitor and those are only for the FCC regulation i think it not right .I'm not judging you job is perfect and you detect the fault so easy great job nice video.
TV-urile vechi aveau obiceiul de a se strica de paste sau de craciun ;) Acum si PC-urile noi?
Is it working when you remove gpu?
The display port is on mainboard ,not on the gpu board, so the cpu has integrated graphics and graphic card is just for rendering.
You say it's easy to repair but that's only if HP make the parts available
We need right to repair law, schematic diagrams, spare parts must be given out
Happy Jesus Day to all who have no converter to hdmi port
Repairs are always welcome, but a little Bible study is also allowed, right? Maybe you read carefully the entire chapter 17 of John in the Bible.
Very valuable and instructive sayings of jesus!
God bless you Sorin & Family!☺🙏
usb C to hdmi possibly working :)
No capacitor, no short. 🤣Easy money ☺👍
❤❤❤
Capacitors revenge 😁
1. I'd charge extra just because I've fixed the board. Why? Not many ppl in the UK fix mainboards and that's why local shops are coming to us more and more.
2. I'd be OCD on those 2 caps :D, I'd try to remove the remnants and solder the same size max Farads. But, without them, still should work as you know. So, no big issue. I'd not even call a Dodgy repair.
3. There's no AC, OK? There's PWM, so DC modulated as it's a Pulse Width Modulation, and always you have a diode after ;), or a buck converter :D. People might believe that they can expect Pure Sine wave there - but, there's none. So, better to not confuse them. For those who don't know what I meant. Please read about the difference in between AC and DC, PWM and MPPT to understand it. Worth checking fly back, half bridge and full bridge to learn even more.
As Sorin have mentions the Switching Power Supplies, worth knowing what extra filters like LLC - inductor, inductor, capacitors are doing in let's say a half-bridge. They are lowering the noise. So, worth learning about LLC as well.
The last one I'd like to mention is that when we're talking about the interference, there's a difference in the analogue devices like the Valve amp, and the computer which is digital. In the analogue devices you can have far more noises which will give you additional sound/noises if you won't fix/design the circuit properly(for instance loop in the ground on the PCBs). The PC will compensate it as have many filters, coils, capacitors + many layers of PCB which are common ground as well. So, it's much easier to manage these noises comparing to the Valve amp.
4. I though Sorin has all the cables :D, and the Display port won't be an issue :D. Sorry, my bad. Sorin, can I send you an HDMI to Display port cable?
I think u the one who doesn't know ac dc definition
There r two definition for both here, bipolar/unipolar as the formal definition
The other definition is changing waveform, any changing voltage is considered ac in model even if unipolar, u call it ac with dc offset to be more accurate
No, ppl don't refer sinewave as ac in definition
If u wanna call it that, even square wave is sine wave if u learnt Fourier, so it is ac?
To understand which definition ppl r talking about, context is important, in this context, he is correct in saying ac, but it is called impedance not resistance
@@urnoob5528 Thank you, will learn about it. I never studied electronics, just fix it since the '90s. So, there are still things which I don't understand ;).
But, if I won't open my mouth, I can't learn as I've got ADD and can't focus as easily as others. So, for me practise is how I learn.
Again, thank you for this, and for sure I'll save it for later to learn more about. :)
@@urnoob5528 just checked with AI to save up on time :D. It turns out that you had a valid point that the context matter.
But, I'm no wrong, nor you are not :D. It is for real not a pure sign, and we can call it if we want to use AC term " AC with a DC offset", or a complex AC waveform.
Happy to learn more about it :). Have a nice day :)
displayport is the future
You're a Ham radio operator? What is your call sign?
He is
