I smile ear to ear every time I hear "We have Picture" "Dats crazy!" That was a nice repair. Be well.
Sorin The chip produces 3 voltages that are needed to power DDR4 - 1.2V and 0.6V and 2.5V
that's why it's not producing an image but still charge the battery
a yes, the 2.5V was for ddr4 ram, it is double the 1.25V.
@@orange11squares but ddr4 is 1.2V
@@maklogetrich2378 it is using the 2.4 as well, just try and measure the caps on the ram stick.
pins:
VDD Supply Module power supply: 1.21V
VPP Supply DRAM activating power supply: 2.5V .
He is great
This dodgy cap was consuming all the current that chip could provide on that rail that's why the voltage was very low there. Sorin's way is great man.
I repaired a laptop myself, I plugged in charger and checked where is the heat. I felt a sharp sting in my hand, it was a little capacitor that would instantly heat when plugged in. I removed it and magically my laptop booted on and worked.
"we have picture - that's crazy"
we have pizza
Wow! Haven't seen Sorin use alcohol short detection for quite some time.
...then you need to watch more often. If you don't have a thermal camera, IPA is your next best friend... :)
Wise man like Sorin never fail to impress us with something new every day Thank you Sorin for sharing with us we have nothing to give back to you
Niciodată nu am găsit în scurt un condensator, nu am norocul ăsta 😂😂😂 am înlocuit numai cipuri... Cred că ești un om norocos❤
Salut, mi se par super interesante reparatiile de electronice in special de laptopuri... Ai vreo idee de unde as putea sa incep sa invat notiunile/lucrurile de baza pentru a face o depanare corecta si pentru a efectua o inlocuire corespunzatoare si totodata sa invat ceea ce face fiecare componenta?
@@dap3592 Da, sunt kituri montaje electronice de confectionat, cărți de electronică începători, începi de la o diodă, și parcurgi treaptă cu treaptă, după care începi să-ți iei un latcon mic de lipit, un aparat de măsură mai ieftin, înveți să măsori cu el, curent continuu, alternativ, rezistențe, diode, tensiuni.... Încerci să identifici mai întâi etajele din care este compus un anumit aparat. Cauți schema și faci unele măsurători cu tensiune și fără tensiune... Eu am învățat singur prin studiu cărți tehnice de electronică începători pănă la mai complexe. Înveți să citești o schemă, să știi rolul fiecărei componente electronice, sunt multe dar dacă-ți place, înveți sigur100% după care incerci să-ți repari singur aparatura defectă din casă apoi a vecinilor sau prieteni, satisfacția va fi maximă.
@@dap3592 Cumperi cărți sau reviste de electronică analogică pentru începători, după care un letcon mic, fludor, flux, aparat măsură și kituri montaje de ansamblat sau pe Placă de încercare, după care studiezi ce face fiecare componentă incepand de la un fir conductor....până la tranzistori , înveți să manevrezi și să masori corect cu multimetrul cumparat ... Durează mulți ani până stăpânești... după care electronică digitală combinată cu analogică, software, măsurători pe placă funcțională in tensiune și fără tensiune ... E mult ce-ți spun dar eu am învățat singur fără ajutor. Am inceput de la un radio cu o diodă, o împământare, o antenă cu un fir de 20metri peste copaci și o cască telefonică cu impedanță de 2000 ohmi... Succes! Electronica o incepi întâi ca hobby după care dacă mai ai timp și ani de trăit, profesionist...😂😂😂👍🇷🇴🇷🇴🇷🇴
You're very informative when you speak. Love all your videos!
Sorin that’s a nice quick fix thanks for sharing 😊
First like and almost first comment, since I already know this video contains the essence of the resolution of the issue... Knowledge!
Wow Sorin, I think those components are communicating with you😅😅
Thank you very much, Good job.
"We have Picture" "Dats crazy!" 🤣🤣🤣🤣🤣🤣🤣😍😍😍😍
Thank You very much for Your channel!
Dead Capacitor = Nice Pizza!
Egg omelette pizza special😮
The battery was not charging, or probably was so low because the short depleted it so it was taking the recovery charge with very little current.
Good job mate
Great work
Those thermal cameras are amazing
Well done 👏
nice repair. sir, can you make a video about those power chip, explaining the in-put and out-put , and when we can inject power inside, ...
So did you put a new capacitor or you just leave it like that? Thanks for the video!
Your video make me smile 😊 say hello to my little friend ✂️
You didn't put another capacitor?
you can't have a shorted capacitor if there's no capacitor😄
8:32 "let's do something stupid" xD
Say thanks to the thermal camerao
Nice proper motherboard...💪💪💪
Hi Sorin can you please make video from power supply the mob cables adapters configuration setting up ?
thank for educating us but you should have showed us the reading of the damaged capacitor because we might not have thermal camera to dectect that, i just want to know if the capacitor was reading zero ohms when you switch meter to continuity
If you think this as the thevenins theorem , the heat will be produced by the lower resistance part in parallel
I would never suspect a shorted cap that measure 40ohm it would be intresting to see the reading on both the motherboard and the cap itself after it was removed
BiG LiKe Nice repair👍👍👍❤
How did you find the place to inject voltage?
Thanks Sorin, i learned a new one more...thanks very much for sharing... if i can i'll help you bayng the discord private channel asap... but is hard going on.. with your teaching i succed in more complex repairs... amazing your passion that i have me to... bye Francesco Timpano from Florence Italy
sorin again lucky customer 😄
Nice! 😎
:( Sorin seems that the obs beeper filter is not working :(
😂😂😂 we have picture i need my pizza 🍕 nice job sorin
Smooth
What is the brand of thermal camera?
I have not seem that you have not replaced the capacitor, will the PC now be working without the capacitor??
May I ask (generally): The surface mount capacitors, how do you tell which way to put them on the board? Im sure they are polarity dependent like electrolytic capacitors? Awesome video once again! 😀😀
Ceramic caps do not have a polarity.
Brilliant, I'm back onto the right learning track.
How can you be so sure?
Components and their characteristics, still learning.
No capacitor, no shorted capacitor.. might have been a good idea to replace it though.
I do not see a join button anywhere. Where is it?
Say hello to my little friend 😀😀😀
does not replacing the capacitor have no impact on the chip ?
No
It depends.
When there is enough capacitance around, it's gonna be fine.
"Can't use my little friend while camera is rolling".
"Oh capacitor did vanish while camera recording cut for unknown reasons".
I have a question for you if you don't mind but I own 2 hp elitedesk 800 G2 mini computers
One works %100
the other works but as soon as I plug in a usb hard drive the computer becomes unresponsive I have tested 4 drives and it's the same also the display port does not work but the hdmi does and the ethernet randomly not connecting to the internet reboot the pc and it's all ok again in thinking it's the main board or am I missing something
Super=)
Sir Please help me to repair my hp laptop it only indicates charging orange light but doesn't turn on.
You removed the capacitor, but didn't put one back. WHat is the role of it?
👏👏👏👏
Why still 30mA after removing dodgy cap? It is supposed to be 10-20mA
👌👌👌👌
Pizza!!! 😊
👍👍👍👍
As long as you don't start saying "say hello to the bad guy", then all is right with the world.
Well, this job could've taken a lot more time of you hadn't the thermal camera.
40 ohm dead capacitor, this is strange
The audio quality is poor
But the rest is fine 😊
Why the ram memory so expensive
Because older RAM is no longer made. So getting it new with zero supply is much harder.
Sir my Lenovo legion 5 2021 with r7 5800h RTX 3060 after updating the drivers the screen turns black and it show RTX 3060 not detected plz give me a solution it’s like 1000 dollars into water plz help me out
Not charge batery 140mA !!!
The battery is probably already nearly fully charged.
With most faults being with MOSFETs, power management chips and.caps. why isn't there any efforts in making these devices larger to handle more power rating and reliability. Usb D will probably be same fragile piece of poop.
why are these capacitors not necessary? and aren't they providing a path for electricity so without it that path is open?
Cap can't provide path (except for AC voltages). Is there to stabilize chip. I would replace it but whatever it supplying have most likely additional caps next to it so it's not really necessary, with big planes used in laptop boards resistance is most likely negligible anyway.
@@gorjy9610 i am use to large capacitors in AC applications for electric motors where they are the pathway for the power.
@@zippythechickenYes, well that's AC
Laptops use DC coming from a switch mode power supply. Any capacitor connected between a power rail and ground is probably there to "bypass" the AC to ground. There's usually more than one capacitor in parallel doing that so you don't necessarily need to replace the capacitor you removed
Time has shown that these SMD capacitors are garbage and have a high failure rate... That's sad :( Makes you wonder, how many devices have made their way to a landfill because of a failed 1 cent capacitor. Oh, the horror!
i really hope you are romanian.
This time i am first😊
🍕
i would like a penny for every capacitor that i have had to replace over the years
to fix a strange fault.
Thousands of innocent i/c's must have been replaced before the faulty capacitor is found.
Every year, thousands of laptops die from dodgy capacitors.
A few cents part that have contributed immensely to trashing our planet...
You don't repair mobile phones anymore?
قولوا: لا إله إلا الله محمد رسول الله، تفلحوا
And Jesus is the son of God.
Battery doesn't charge!! (140 mV)
Laptop came for not powering on. Not powering on is fixed. Fixing stuff customer didn't even ask you to fix is best way to make life hard for you.
😂 bad thingy
Incredible! Let's be friends :)
over a year not use plier
🥲
