Hi Mr. Sorin, I hope you'll get better soon.

The 3 dislikes are from hp designers 😂😂😂 for me great video!!!!

We can't repair this laptop, you can't find the ic. Sorin: hold my beer.

Great work, I did this "mod" once too, but I've connected the input of the buck converter straight to 19V, desoldered a 100k resistor near the ceramic input capacitor which is connected between input and Enable pin of the IC and soldered a 100k resistor between 5V rail on the motherboard and the Enable pin of the converter. That way the 5V power supply can't be overloaded as It is only Enabling the converter, not actually powering it.

Hello Sorin, I wanted to say a personal thank you for all the content you upload and the time you take to break things down into understandable parts. At the weekend I fixed the kids old Amazon Fire 7 tablet we had that had broken after my father had already changed the charge port. As it was already broken so I had nothing to lose and with the confidence I have gained watching your work flow videos I successfully bought it back from the dead with a quick reflow of the connector. Thanks again, hope you feel better soon.

Great work Sorin! Thanks for sharing and I hope you feel better soon.

Amazing. Brilliant mind. I never seen that before. Another unique repair lesson. Thank you Sorin. Greetings from Bulgaria.

Wow! Sorin, you're a genius! I'm blown away with your troubleshooting skills. Best video ever. Keep it up Teacher

Had a laptop that wouldn't charge or turn on from the main 19, but work from battery, I built small charger and the laptop still working after a year. Great job sorin

Wow, keep proving that there is no limit in troubleshooting a dead motherboard, I missed the last video where you first you the universal power supply. Right now am going to check it out. Is really wonderful having you here get well soon and please we need modification using universal power supply. Thanks and God bless

Excellent return with a hard repair master, recover your health, greetings from South America, Argentina

A practical solution to a difficult problem even when feeling the effects of flu :)) Hope you have a speedy recovery .

This Video goes straight to my youtube list "Instesting Repairs". Good Job Master!

Great Video, showing how to overcome missing chip...Wow Good idea Mr. Sorin...Many thanks for sharing this issue

You are skining a wire the same like I use to do years ago. And I love to see you repair something like this, peopel learn alot more than from someone changing ports all the time.

This is really a nice fix, very practical thinking.

you still do magic even while not feeling well. Wonderful

That was great, creative thinking, thank you! 👍 Hope you get well soon 🤒

l am from sri lanka.l watched some of your videos.My knowledge of English is bit lacking but l learned a lot from your videos.Thank you

Get well soon Sorin. Great hack and repair!

Thanks so much for your vids! Really it is so greate to see the way like eastern guys would do, like me to (eastern german) 🤣... You simply understand how things work / should work. I simply watched yesterday my whole working day your vids (also lenovo) but... Not every lenovo is done like this! 😁... I do have one here and just the fuse is gone as well as the first mosfet, i tried it your way with 19v on the other side and it simply start working. I really try to understand what you are doing and why, not only doing same things without any clou. So big big thanks for your vids!!! And by the way get better soon! ☺️

Hello Sorin nice to see you :) 58:50 You used step down converter in video: This was a hard one, Tv's - Diagnose and repair / power supply repair/replace/improvise

I bet this man can build his own laptop.

You are always surprising me! Great repair!

Everything is fine...hopefully :) Great video, I did enjoy it and learn something

Hi sorin, I hope you feel better, missed ya this week

Nice job, Sorin! This chip is SY8286A

Great work , your company would be lost without you!

Hi dear sorin. Great job. I think about another modify. We take awire from the cap 1.7 of the processor then we but adaiode then we connect it to the cap of chip. U r agood man mr sorin . Thanks alot

At the first glance I thougt "WTF, connect it to 5V not 19V for lower voltage difference" and insulate that module from behind with even some tape! :) Anyways - good job as frig! I couldn't be more crative :D BIG THUMBS UP!

WELCOME BACK , MASTER SORIN.

Sorin did excellent on this one and even the chip might have cost more and flaked out again. So with those outlets it seems it will not freeze up. Good one! I think you should freeze this bodge into place with hot glue.

Get better soon Sorin! Cpu vcore is 1 -1.2 v on those models and vram is 1,3 - 1,4 on ddr 3

Wow impresive modification and really well understand !Thanks

Only word for sorin is # Genious# Man with top notch skills

Sorin! You are a master of the universe, how to be like you? Great job!

Mr. Sorin I love to watch your videos. I learned a lot from you . 😀 thanks for making video about repairing.

Very professionnal fix.Thank's sorin. Take care of yourself.

what a great work, hope you get better quickly ,

Finally Friday, finally Sorin time :))

Stop vaping that flux, good job

Good day Sorin, Always love watching you work and amazed at all the tech stuff you have to make the job a bit easier and provide us with magnified footage. I am in the process of searching for my first laptop. I wish to use it for work conduction heating cooling energy graphs, account records and simple billing info that may be downloaded to desktop software. Since you see and reapir many makes and models, Can you please provide some insight towards what you may call a reliable unit. Much appreciated.

nice fix. I might suggest starting at a lower voltage initially on an unknown power rail as higher voltages can obviously kill it (and killing the PCH is likely to make the laptop not worth repairing), but a lower voltage should be fine and just will cause things to not work properly at that voltage, then you can just raise it until things are working as expected

Great big job. Thanks for sharing with us.

Thanks Sorin, that was a great fix.

Fantastic video, master Sorin. Thanks!!!!!

Great repair! Maybe you can now get more CPU information and read the voltages from the BIOS or CPU-Z and figure out, what voltage there should be... i think it's 0.8V It's running now but could be the Voltage is still too high... you said yourself it's on the top limit of running or not.... i'd lower it to find the lower limit, THEN bring it to the middle.

You are wonderful teacher and behaved one coz thing are understandable

Fantastic video teacher, Thank you !!!

This was a good one.... great repair

Put a couple dabs of your infamous hot glue to add more strength to the power supply board. I do like your dodgy repair jobs. It is why I am watching your channel. Thanks.

sorin more workshop please, trust me its very interesting for us you changing batteries :)

Great video, thank you Sorin!

Love see you back....Waited a long for new vedio ☺️

OMG. This man is laptop whisperer ...

You are creative genius Sorin

Sorin! You're back! 😄

To check for heat spray some dielectric on the board. first spot to dry is the HOT spot :D

Hey Sorin thanks for the many years of learning as for the chip you could not find just use the first 4 codes of the chip it should be no problem finding that one and others like BAA5 BAA7 anyway back to learning for me :D

Great fix. *thumbs up*

So now, the PCIe is plugged into the USB to get current... while the USB controller is plugged into the PCIe to get connection to the CPU. Nice job. :)

dang this was a great lesson sir !!!!!! so great thanks so much!!!!!!!!!!! following you from pasadena tx

really killed it BIG TIME :)

So essentially the customer now has a very handy hardware tool for undervolting :)

Supper work...thanks

Sorry your sick Sorin but what a lot of fun I have watching you and your thinking process.. Smart fella! carry on and we will see you later..

sorin i think a better idea is to use 19v rail and connect a mosfet inline from the output of your power supply to the input of the rail of cpu and connect the gate to the 5v power supply. that way you wont worry about current limitation.

thenks for this lesson proffesor.

very nicely done !

Best of all time. Thanks.

Hope you get well quickly, it's no fun going to work and feeling so ill :-( Your face lit up when it worked with your psu, i knew you were going to supply it some how lol :-D

So far on my book you are the best electronic wizard I ever seen on KZfaq. I learned so much from you my hat is off. You blew me away

FRIDAY FRIDAY FRIDAY ! Hope you feel better

great job !

this is fantastic job thinking of mind

galing!!!!!!!! you are genius!!

Very interesting trick. I will remember it

great!...I hope you'll get better soon... Sorin I didn't understand one thing: a 16-pin chip only for a voltage of 1 volt? this 1volt what feeds?

Hi mr sorin we love u from morocco, when u want one day to visit morocco i say welcome u and your family to my home

you are genius

that was a nice idea ever

My DC Power supply is one of the most valuable tools I own. Not only is it great for diagnostics but also very handy for testing and powering circuits or powering little projects!.

عمل جيد سيدي اشكرك على هذه الفيديوهات القيمة والمفيدة

good job Sorrin, I hope you get better soon and wait for next video. We saw that you have a lot of boards for spare. Is this means that there are cases that you cant fix them and you show us only success fixes? I mean that if there are cases that is not repairable they can give us experience we can learn from them

Get well soon sir...I pray for you..

Man you are crazy 😜 modifi a power chip. Nice one and happy customer . Tanks Get better soon have a nice weekend. Ps When it returns what can you do ?

Good job! its fentastic 🤩 👍👍

Fantastic!! Felicitari!!

A "all in one" cpu as you call it is called a SOC, System On a Chip. And blank screen on Windows shutdown is not shutdown process, it is already done. The blank screen storage activity is actually hibernation process, it writes RAM into the HD/SSD. It is because of the Windows Fast Startup feature, Windows does not actually shutdown when you choose shutdown from the start menu. It does a hybrid shutdown and suspend to HD (hibernate) function which enables Windows to start much faster (on most cases, not all). It is also a function that may cause lots of issues with Windows. If a service hangs, shutting down the Windows and starting it up again does not fix the issue. You have to choose restart or disable the Fast Startup from power options before shutdown. When you disable it (or disable the hibernation, which also disables the Fast Startup) it actually removes the "blank" display in Windows shutdown. After that Windows shuts down much faster and it shuts the computer down also (almost) immediately after the display goes blank.
