Even a non-repair of a no fault or a no fix because of damage beyond repair that isn't cost effective is a valuable learning experience. Watching you go through the process of eliminating possible faults is a learning experience you can't learn in books or even in a school teaching electronics. Give me this type of learning and I will do it all day long. Going to a physical school can teach you electronics but it does nothing to teach repairs in real world scenarios. Keep teaching and we all we keep learning. Thank you so much for going through the painful process of teaching. We all know you don't have to do this but I for one appreciate what you have to offer. Thank you again.

Wow, you do have patience dismantling this laptop. If it was in my hands I'll probably be fling 3 floors under, through the window, before getting repaired. Everything seems odd in this laptop, from the weird board design to the amount of screws they put in. Congratulations on another job well done.

Dude you are a genius, not to mention the (patience of Job). Just seeing you do your job slowly, calmly and patiently makes me wanna continue watching lol. When you stop to say "hmmmm I don't know what's wrong" has me also stopping to think and concentrate too. Its exactly like the saying 'laughter is contagious' lol.

Your videos are always extremely informative, interesting and very helpful. Keep up the good work, I enjoy it very much.

Thanks Sorin .Have a great weekend . : - )

Actually, everyone has what interest him/her in watching the videos of this man. For me, what interest me and make me happy most is the way he always go about the troubleshooting thing, it set me laughing sometimes menh😁😁. Who else could imagine that…

Thanks for the petrol trick. I learned something important today!

Once again, the circuit warrior has triumphed. Thank you for repairing live, sharing experience. Greetings from Argentina, South America.

Congratulations on another job well done.

i second Muthanna Tech, a special day for caps..thank sorin for the very nice tutorial

Salut Sorin interesant o sa urmăresc toate postarile.

I love your video because I understand every single word too my English skills is not high so your explained is very good keep going

thank you Mr.Electronics repair school

thanks ...i have repaired my laptop by your guidance in video ......thanks

Well done, master. Nothing more to add actually.

Imo you are the best technician on the net.👍👍👍

finally ... i was able to watch Sorin actually "replace" a capacitor ..... 😁 dont get me wrong i totally agree with him ... most times there are enough on the lines to compensate ... for removal of one or two

great job thanks sir for repair this

You are an inspiration.

it helped me with a dell. tnx!

I also replaced a capacitor on a e7450 but in my case the defective one was the one closest to PQ700

Dear Sorin, you definitely deserve a thermal videocamera . Thumbs up if you agree 👍🏻🤝🏻🇳🇱

Why replace the capacitor?

May be it’s a short cap.day Sorin haha Thank you for the nice video

Nice one. Thanks.

Before watching, shorted 19v zener diode on the 19v or a cap Lets see if im right

Thanks for your videos 👍

Hi Sorin, great video as usual! I'd like to ask you a question, though:) I'm wondering if those test probes you use with your multimeter were curved that way or maybe you modified them? I was looking for similar ones, just like yours, with curved needles but haven't found anything. I'd really appreciate if you could tell me if maybe I could buy such curved leads or I'd have to modify straight needle ones. Thanks and keep up the good work, cheers.

great job

Appears to be some sort of serial flaw, ceramic caps would only break through and shortcut with a massive over-voltage, not just a temporary peak, maybe they took caps with 16V instead of 25V breakthrough voltage during manufacturing process by "mistake"? In that case, replacing all ceramic caps of same type on 19V should be advisable.

Oh NOOO!! I have this exact problem on my e7450 that just appeared today while i was using my laptop. I really don’t know what to do. I dont have the skillset to repair like you did.

Thank you for the nice video

I have a E7450 with similar issue.The Mosfet on PQ700 is getting hot too but the caps on the other side of the board become hot too.. I can't identifie which of the caps is the one. They get hot when you apply 10V 3A but it looks like they were it all three together. So I removed all 3 caps and still got the short on the board.

Mr. Sorin, do you have a technique for remembering which type of screw goes where? ...I am always fascinated by how you seem to manage by putting them all in one big pile!

Hie Sorin , I have a question ,in a situation where you don't have a power supply like yours is It possible to use a 5v/2A fon charger to find out which component is shorted to ground?

If the clips breaking what do you do? Hmm now? It’s a nice laptop.hot glue? Or buy a new part? It’s a triller watching you open the laptop clips always thinking something have to break. You are the best nice find every time Thank you have a nice weekend

I have a Dell Latitude E7240 which powers on but no display and no hdmi output, when I plug the charger in the system boots up without display: - Power button led comes on - Hard drive led flashes once very quickly - Battery led comes on for one second - After 4 seconds the power button led goes off - After another 4 seconds the power button led comes back on and stays on, the hard drive led flashes once very quickly The green leds on the actual msata SSD light up If I leave the system in this state then the cpu and heatsinks get hot and eventually the fans will spin (but still no display) Pressing the power button once will turn off the system (cpu will cool down, msata leds will turn off) I’ve tried the following: - Performed hard reset / static discharge, disconnected and checked cmos battery (3v on multimeter) - Replaced RAM, msata, screen with known working - Tried booting while holding down ESC, D, FN keys - Tried HDMI output (no output) I’d really appreciate any other suggestions / tips, could it be a corrupt bios? Thanks in advance

thanks Sorin

we bought 20 7450 in our company. after 16 months they all got broken :)) they all had problems but not the same problem :)) some of them had problems with charging circuit, others gave blue screens random, others had problems with lan others with wireless :))) other with mobo.... we will never buy laptops from dell. (greetings from Romania :) )

Is there a infra red heat vision camera you can get, so can see components heating up when applying current? Was wondering.

idol,i have same model but no power...can you share the schematics?

Hola tenes el esquematico de ZBU11 LA A963P Schematic Dell Latitude E7450

Hi Sir , thanks for the video , could you please show me in the board where is the position of PU111 , thanks .

nice. enjoy weekend.

Maybe the owner has a nasty 19v psu thats spiking every laptop the owner uses it on?.

Another nice job.

It was one of the first 3 caps you tested before removing the MB. I wonder if they are near a port where they are plugging in a bad device.

Good morning friend, could you provide the electrical diagram of this board there, or could you tell me what the capacitance and working voltage of this capacitor is, could you also tell me what the inductance of the pl3 is?

Sorin s going to have dell laptop nightmares now lmfao.

Great video, but please help me fix an issue with laptop over heat and blue screen.

We replaced the mainboard capacitor for one of these and it only worked for one day, stopped turning on again after that....

Needs another stick of ram - have a great weekend also

Salut. Atelierul e in Romania sau in străinătate? Mulțumesc.

I have e7450 i7. Laptop works fine for 1 to 2 hours then freezes. Sometimes pressing on motherboard un freeze but for some time as long as i keep pressing. It could be dry solder or something else but i don't know exactly from where to start.

Yay! More senpai Sorin videos!

1st time replacement of a cap😵😀😀

Good video Do you have the schematic por this model ?

Insane laptop design, tons of screws expecially for holding the motherboard...

My company only orders from Dell and these Dell laptops are so prone to short-circuit. I have 4 turned in by different customers using different Dell models. I can't seem to find a local repairer who works on mobos. They all tell me I need to buy a new motherboard and replace it. They're not skilled on finding the bad cap and replacing it.

I have a question about my laptop. All of USB ports is not working. And when charger plug in sometimes screen going to off. Or the laptop is reboot. And the led indicator is not working properly . My laptop is dell inspiron 3558. Thank you so much.

What a nightmare of screws !! :-)

Please, what is the capacity and voltage of the capacitor?

Boss, I have a problem with my HP EliteBook8570p it will power on, but it will not display on the screen, I have to try to change the memory and the processor , please i need you help Boss

How do you measure the current in a closed circuit? And in 31:38 you removed the defect middle cap but in 33:35 you replaced the last one , why?

Thank you Sorin. But Once more, how do you decide on the replacement cap? by shape and color or ...?

hello sir , what about a buzzin noise when i unplug the battery but no power on even when i plug it no power on but the buzzin noise disappear

What is that part called? I am experiencing the same issue and want to find the correct item type.

i am trying to find bios chip if you could help please

Sir I have a dell xps 13 9365 2 in 1 it stucks on Dell logo Can you help please

I have that same machine, the crazy thing is that it turns on when it wants, you turn it on, it turns off marking the hard disk LED ... has it happened to someone? 😭

(ok, dadz not ok. dadz verd!) I love your videos mate

Guys, what is the value of the capacitors? 22uF ?

Sorin, you are in V mode and not Ohm mode.

Basic thermal camera is like 100 quid it would save you some time in finding short....

what fluid did you use sir to test the shorted capacitor?

Touchpad and keyboard not working how to fix

The value of the Capacitor? in the time 30:55 ???

Cum gasesc lichidul in ROMANIA?

Hello there what is the black cable attached to usb?

So,,, what´s going on? you took out the middle cap and then you changed? To the first one?

SIR DO YOU HAVE DIAGRAM OF DELL LATITUDE 5530 I5 12th gen thanks

What is the liquid you use to find hot spots???

Hello Sir :)

Just think I see you're working with your left hand

Wow that thing has more screws than a hardware store. Hope you got paid good for that job.

👍

Dell inspiron 1525 laptop fault is not charging plug in charger battery replaced new what I m do

I am older than you but I want you to adopt me. I want you to be my father. The father I never had.. Oh, is that the time? Don't tell me i've been up three days straight? All right. Scrub that. I'm gonna go get some shut-eye... >

Don't hand over the phone/tablet etc until they have paid :)

You should really invest in an infrared camera!
