HP Z2 Mini G4 Workstation - No power, dead - Motherboard repair - Classic fault 

Happy Easter to all removed capacitors 😀

So rare to see a big manufacturer, specially HP doing swappable components these days. Kudos to their engineers for getting passed the bean counters.

No replaced capacitors. This is the Sorin that we know and love.

A1, Happy Easter Sorin and community! Excellent, Thank you❤

Happy Easter from Sri Lanka 🇱🇰

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!!

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 to everybody 🎉🎉🎉

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

2 more capacitors to replace on the next video... 😁😁😁 Happy Easter Sorin🕊️

Happy Easter Sorin, I hope you found some nice laptop with some chocolate easter eggs in them!

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.

Later that day .... Ring Ring ... Hello, Sorin speaking, how can I help? Caller ... Hi Sorin, this is Tony from the FCC ......

Nice fix. I hope they still making a pc like that.

Happy Easter from Germany and get well

Some displayport sockets can also take HDMI plug.

Very nice workstation. I miss the times when both CPU/GPU could be changed on a laptop without using soldering tools.

Happy Easter Sorin , your family and community !🐰

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

The Master strikes again. Great job.

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

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!

Sorin you need to buy A mini dremel ... it's very satisfying to "consume" a bad welded capacitor with this thing :) ( also welded mosfets )

Happy Easter 🎉

Doing repairs today as well. Happy Easter

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

Im not really electrician but i love to see how you work and the pleasure you getting repearing these devices

This is a proper nice workstation hence the high quality components and design

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

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 🙈

Спасибо Сорин! Компьютер прикольный. Выздоравливай и не болей!!!

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

Thank you , you are the master of electrons i salute you.

Always love to see modular computers.

It's amazing how many people have no idea about how good the HP Corporate Range of Computers are

I just saw this on your website: "We Use original components" :D :D hahahha ... I love you dude. Keep it up

👍 and a happy day to you to

Happy Easter Sorin🔥🔥

Happy Easter Sorin! Take some lemon and honey for your cold. Take care!

Good job mate

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, Don't you ever get a day off?

We need some capacitor eggs to make new ones. Good video.

Well done Sorin

happy easter sir. God bless

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.

Such a nice Lesson Master..thank. You for the video! SAY HALLO TO MY LITTLE FRIEND 😂😂😂😂

Great insight to capacitor functions. What caused the fault to begin with is what I wonder. GM

It's called a busman's holiday, Sorin.

Happy Easter everybody!!!!

Proof that thermal camera is fancy toy but visual inspection is enough.

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 :)

Happy Easter Sorin and Diana. From India

Greetings from 2E0KKV 👍

Proper professional workstation - not a consumer product. With a price to match no doubt ;-)

I cant believe that it had removable cpu, kudos to HP for making a change.

Happy Easter Sorin from argentina

Happy Easter :o)

Happy Easter 🐣

thanks

Ah-ha... I see the BIOS battery that needs replacement after 5 years or so. Picked on up for $210 (US) and this thing is really fast ! But the BIOS batter is bad, it take a full minute once plugged in to start (back power light flashes - front power light goes on - then off- then on) and then the PC starts. It will be OK unless you unplug it, then that minute startup procedure starts again. YA think they would put the plug on top, and just plug in a new battery.. newer models do ! !

P.S. I enjoy your site. Thnx. GM

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 😁✌️

Alien got birth from that capacitor.

Eek. Exposed socket pins give me anxiety. Also, how hard is it to diy a socket replacement? 😢

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

10:20 listen carefully the sound. I hear like the pins inside the socket being touched. I wonder if they are straight now? xD

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.

You could fast forward the MB removal so there is a video sawing how to remove it. 😅

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?

They should also have the capacitors in sockets.

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.

Sorin rules, no capacitor = no shorter capacitor - burned fuse = proper calibrated wire 😂

Hp's version of Apple's Studio?

happy Easter Sorin kerala India

Hi, can you tell me how you always find the main power rail so quickly to test for shorts?

TV-urile vechi aveau obiceiul de a se strica de paste sau de craciun ;) Acum si PC-urile noi?

Dear bro Whats the best way to make devices live long

Love peace and happy Easter to all war mongers. Nice repair.

The capacitor looks like an alien came out of it.

Happy Easter 🦆

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.

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.

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.

We need right to repair law, schematic diagrams, spare parts must be given out

usb C to hdmi possibly working :)

Is it working when you remove gpu?

No capacitor, no short. 🤣Easy money ☺👍

Removing components with pliers risks tearing traces off the board!

You say it's easy to repair but that's only if HP make the parts available

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!☺🙏

displayport is the future

You're a Ham radio operator? What is your call sign?

Capacitors revenge 😁
