People!! This man is sharing so much knowledge. There is so many of you that are saying that he should be charging for the lesson, and yet he only have 17 Patrons? Support him and this channel! 😙
That was inspirational, trust yourself is the message. It just show how good your diagnoses was that the other repair shop couldn’t fix so passed it on to you, great, that will show them! You are the best 👍👏
A few years ago I was working as a break fix engineer for a Dell partner, pretty much just visiting business customers replacing motherboards. There was always a hold your breath moment when powering up for the first time, the diagnosis had been done by Dell over the phone. A lot of the newer laptops would do this when first powered up, no display, restarting etc. I would be about to call tech support when suddenly the Dell logo would appear. Love watching your work. It's nice to see someone actually working to component level
Need Help from motherboard experts. My Dell e7470 was damged from dock area. All motherboard is working fine and laptop is booting but the dock area gets very hot and spark. I don't want to dock in my laptop. Is there any way that i can disconnect the dock area from power. The dock area is a separated slice in motherboard.
The CD3301B only control the DC in , selecting between DC In and the dock connector.I have 4 Dell laptop with this problem one I had to run 7 wires under the chip.you were very lucky that the chip didn`t burn a hole in the motherboard , one burned all the vias around the chip.The chip doesn't create any voltage it takes 3.3v ,5v and 19V and detects if the power comes from DC in or the dock connector
Thank you sorin ; you are a good man because i feel you're trying to help us as you can by your experience over many years .. may you explain how could we diagnose ,test and determine capacitors capacity. For beginners as a new lesson in beginners lessons. Not only capacitors ..also inductors and other common electonic components. Your beginners lessons are very useful and interesting. i hope you continue your lessons for beginners . Thanks again
you are such a lovely guy with lovely way to fix anything without schematics.love you sir.i like to be like you.but i have not even fixed a single laptop.trying day by day to fix one.but i have fixed lcds
When it comes to later Dell Laptops e.g. XPS13 93x0, beside real hardware issues as in this Video, they sometimes stuck in a endless boot-reboot-keyboard lights on/off loop. This is due to a crappy bios (insydeH2O) in combination with some security checks. For instance, due to security checks or corrupted bios regions (Mainly the ME-Region) they turn off after powering. Here, it is sometimes necessary to replace the entire Bios by a donor dump. But mind, the latest Dell Notebooks got more than one SPI. In most cases, there are actually three and the binaries from each SPI needs to be replaced.
BRAVO BOSS! Vous serait il possible de nous faire une vidéo sur les éléments (composants)et leurs référence(si c'est possible) que vous avez le plus souvent remplacé en réparation? par avance je vous remercie ;) BRAVO BOSS! Would you be able to give us a video on the elements (components) and their references (if possible) that you have most often replaced in repair? I thank you in advance ;) I am considering a retraining following a work accident and your videos are very precious, receive the expression of my respectful greetings.
It looked like the chip soldered down correctly and then you said you needed to add solder. What told you to add solder when it seemed to look good. What did you see different? Thanks.
Salut! Iti mutumesc pentru canal am invatat multe cu ajutorul tau...chiar am reusit sa aduc la viata un laptop Acer Travelmate 7730 ( cumparat de la talcioc)... dar am o problema. Functioneaza dar se inchide dupa citeva minute. Pote merge si jumatate de ora dupa care se inchide. Dupa il pornesc intru in bios si sta pornit cind ies din bios se opreste ...nu face la fel niciodata se opreste cind vrea el.am scimbat pasta,rami.... ai vreo idee?
I have this particular ultrabook and my screen just went grainy white and I'm wondering if there is a way to fix it. If I need to replace it, how do I know what to search for?
Hello, i need help with E7470 motherboard. Borad is working good but the cord area is damaged, is short circuit......gets very hot and sparks.......I want to dissconnect the power to the cord area. can you help..?
I unplugged bios battery and repasted my cpu. It never started, i was scared as fk for ruining my 800 dollar laptop. Reassembled several times. Turns out after replugging bios battery it will never start on laptops own battery and only start with charger. Scared me a lot.

Can you help me with the Components. I would like to be ready for all the diagnostic and repair stuff. What are the most used electronic components for this job. If you answer "resistor", "capacitor" please tell me the most used models for these components too. What mosfet Models, what resistor models, what capacitor models, what etc... Thank you very much

People, I have a HP Pavilion laptop, new PSU Brick and new ( copy) battery. Plug them all in and power socket led goes White then Yellow for 12 sec then White again, Battery voltage 15.6 on charge. Win 10 shows 100% charged. Disconnect PSU brick, laptop dies voltage on battery drops immediately to eventually 0v. I have 19, and 3.3v rails. Checked battery out of laptop and voltage on output 14.5 v (14.4v battery) but if I try and power an led (10mA current) output voltage goes on and off in 4 sec intervals. Anyone seen this effect with these batteries. I think replacement battery is faulty, maybe.

Thanks for the goog video, i have learn the step to take after 19v power layer be ok. is to check 3v power layer
I like your style. Nice videos! I have very limited knowledge on circuitry, but I found the repair interesting nonetheless.
Hi is my best teacher.Thank you
Dell needs bios battery, if its unplugged and replugged it will turn on off on off on

Thanks for video. Small question. Why are there aluminium electrolytic smd caps on motherboards. Is there an advantage to them over the chip type?
capacity ... ceramic ... are lower capacity than the aluminium ones ... i think
where in china sir did you buy the chip thanks in advance

Great one!
Nice!
It seems that Sorin sometimes communicates real time with viewers. Are his videos streamed in real time with immediate communication with viewers?
No, they are recorded at work and then uploaded to youtube.
You should download schematics, it saves a lot of time in moments like this.

,any link for the schematics?

hai sorin my wifi laptop not work it show ' no connection available'. Also date clock not work.
Probably, the date issue is because of the bios battery..
Try re-installing the driver or try to get the original version of the driver from official website. Or try exchanging the antenna cable on the wifi card.
Nice
Please sir how can i know that this MOSFET on mother board is N o or P channel?
