Dell Latitude 3400 repair - This is my Monday, yours was better? 

Burned board with a whole in it , "the board is fine" proceeds to apply rosin " yeah rosin is good for you " . This guy is a legent .

Don’t forget your RAM memory inside the laptop !!!

LOL - well that's the quickest capacitor removal I've ever seen!

Northridge fix always talked about not going down a rabbits hole. I reckon this was a great example of that.

Thank you for spending more than 10 minutes on this attempt, it showed us when to quit. This laptop goes into the donor pile. 🙂

12:39 "And it's looking good. I mean for me, I have no problems with this board looking like that. No issues. It's fine. Everything is fine here."😂🤣😂

We always learn from your successes and even more from your fails Sorin, especially your fails. Thank you!

"This is fine" - Capt Sorin on the bridge of the Titanic!

Fair play to you for sharing your soldering techniques 👍

Always enjoy watching your videos.

My Monday? Drop off two printers. One fixed, one not worth fixing (even though I tried). Fixed someone's Outlook email password onsite. Revisit a tablet repair, was not turning on, now not turning off (they'd chimped the power button again). Send iPad 12.9 for UV gluing screen (can't do that here), Lined up imac and laptop upgrades to ssd etc. for tomorrow. Also some web stuff I get paid for. 'Nuff I think. Sorin time 😀

i really like this video and i can't say you're getting old, i know that the day when you will forget how to use the multimeter will be a red alert till then i know that you will be able to fix hunders or maybe thounsands of devices. BTW sorry for not participating at cofee time in the weekend. Good job in what are you doing and wish you the best

Sorin, you didn't plug in the power button - there is a tiny flex under the fan, you plugged in a board with VGA port

Nice try and nice work finding the fault you’re a legend Sorin 😊

Dont forget your ram memory on the board!

2:41 Love your LOLs 😄👍

You Sherlock Holmes of electronics repair 👍. I am watching your videos to get inspiration to start repairing my old HP notebook, which I successfully broke down recently. However, I struggle between ordering a replacement MB from eBay or spend some time to repair my own MB. That’s a dilemma 😁

i think sorin should show us what an unhealthy motherboard looks like next 🤣🤣

Sir you are awesome whatever is repairable or not but don't mind if you are a surgeon on this laptop repairing concept I am following you always to learn thank you very much sorin sir

Probably the southbridge is shorted and that's putting down the 3.3v and conflicts all around the board like EC chip etc.. P.S. don't forget to take back your ram stick 😉

Thank Sorin, for you resilience to trobleshit but you teach us when to stop.... bye Francesco Timpano

😂 I'm laughing so hard! Healthy board 😅

Maybe keep trying to fix it, we'll just see where the problem continues, don't have to order parts for the learning, it was a very good lesson, maybe keep making a second part 😃

You shouldn't have spent so much time Sorin, thanks for sharing thou. My approach : Removed mosfet, inject voltage onto CPU, check amps and thermals, then charged a diagnostic fee. The other problems caused by too much voltage though CPU out to other components before thermal meltdown.

I learned so much with this video, troubleshooting and figuring out the problem is awesome, if it can't be repaired is a different history. Thanks sorin for share with us that knowledge.

It is important to assess the viability of fixing other damage when the primary cause has been found. Sorin most probably went back to this burned board just to identify 'downstream' damage from a fried CPU.

Thanks for another great video! If you run a repair business, it is indeed no point to spend time on repairs like this. Time is money. it is what it is. Another thing if one can spend all day trying to repair this type of fault.

Can't you lift the inductor and inject voltage to see if the CPU is dead, ie, save time.

You work cheap!!! We won't pull the back off one for less than $100!!! You are amazing!!!

Hello Sorin, you did not connect the power button cable. You connected the vga subboard. on 31:10

Nice

Actually this is an enterprise laptops (dell & lenovo) vpro cpus, always comes without rams ssd and battrey

No layers - no shorted layers.

👍👍👍

My Monday? :D Machine has tripped Live phase 1 circuit breaker, however, on PLC it showed totally different non related error. No warnings about missing L1. Me assuming it would show I looked on wrong path. Eventually colleague came by and after 10 seconds said "Yo, circuit breaker is out." Click and machine started working... Thats my Monday.

I have a similar dell latitude 3400 laptop. Just recently I tried to replace the screen however, the laptop is not turning on now. It is not charging also becoz there's not charging indicator. When I press the power button only the amber light comes on and goes off when the power is released. What's the problem?

Thanks Sorin! A joke on the topic: On Monday, Stirlitz led to execution - it begins hard the week he thought

*Can a Dell adapter charge another laptop?* I saw that the adapter has a third wire, a sense wire.

karbon iletkendir ! yanık bir nevi karbondur 😊😊❗

Hi, where can i get the different dc jack cables so i can connect to my lab linear power supply

You should have tested the cpu with the bench PSU .... so, al least, you confirm is dead. In this case, clearly, 12v got to the cpu. But it's not true that this is always the case if high mosfet get shorted .... because before the cpu there is a big coil .... if the management chip can cut the power very quickly, voltage on the cpu can still be in the tollerable range. Of course, with burn tracks like this one, power was not cut off quickly, so cu is dead.

Don't forget to take your RAM out! ;)

I am trying burning motherboard s but not fixed it was difficult...

You need to measure from Vin to the SW leg, not from Vin to GND on the DRMOS, always, because a high side short is only from vin to SW shorted, not to GND!

Grinding pen? What grinding pen?

Don't forget to remove your Ram stick!

I have Lenovo W530 (workstation) laptop. Its get automatically turn off after running about 5 to 10 seconds. But in BIOS its nit getting off. I dont know what is the matter. If you have any idea please guide me.

dont forget the ram module.

hello sir do you have any online laptop motherboard repairing course

At least some poor sod will not end up with this laptop

Yes, we had Ram Temple inauguration today in India. ❤

no repair. No shortet repair 🙂

it's a little carbonized, but otherwise it's a healthy board

Which hard drive is it?

how can i send you a laptop?

Hi Sorin, I have big doubt. You always plug the charger before test short circuit or Impedance, so If the laptop had came with shorted mosfet, 19V directly go to the relevant section and it will burn. Please explain??? Am i wrong?

For £40/mobo repair it needs to be easy because that isn't gonna get more than half an hour of my repair time. I normally work on an hourly rate as opposed to a rate "per repair" though. People either accept my charge or don't accept it and most realise you can't work for free even if they want you to🤣🤣

Burnt layers is a stop-sign for me. But a proper fuse should have worked 🙂

Then how does unhealthy board looks like?

Where does a board sit- Down on the iron in the middle you can see some liquid damage and a burnt black spot. That's at least another 3-5 burnt chips :/ ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-m_TlSvSitno.htmlsi=kYxLjN9N_-DdLwWk Thanks Sorin for sharing

blue monday kinda slow

I did not understand why people were saying that you should not plug in the charger before checking for faults and even now still believing this is not a 100% right because the users must have tried it many times before it got to you for repair because I don't think any manual would say that if your device is not running just take it to the repair shop and never try troubleshooting because they would want you to buy a new device instead! I mean I still believe if the cpu is gone then it's 99% gone already from where it came to you! which means the power supply method is still very valid and effective from my point of view!!! but why the hell are they making these bga cpus or not make some built in voltage limit features instead??????

I cannot repair a board like this. I will order a new board instantly and my job is done.

Hello🤝👍👍👍👍👍👏👏👏👏👏👏👋👋👋👋

omg please how come u didnt see that this is a VGA connecter and not thr power button's hahahah lol

Why does this board look so angry? 😠

This one is very complicated...

Take back your RAM

That laptop wouldn't be worth more than 40 quid working. Old Dells are cheap and mostly very reliable.
