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

[@retrocomputinggrotto]

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

[@dannydct1]

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

[@shaunmorrissey7313]

Northridge fix is an arse wipe who can't hold a candle to Sorin

[@MattyEngland]

If rabbits hole is proper calibrated, it's OK to enter 👍

[@joseph_donovan]

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

[@electronicrepairservice2020]

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

[@gregorye6075]

[@kblectronix]

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

[@kamkag159]

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 😁

[@KomputaPaut]

Always enjoy watching your videos.

[@ravindraadapa2952]

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

[@aymentunisiano1207]

U have done a great job you have tried but like u say, we have always limitation

[@wisher21uk]

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

[@Timpano_Francesco_Repairs]

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

[@reynaldofigueroa7881]

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.

[@saadr2208]

Dont forget your ram memory on the board!

[@the_game]

2:41 Love your LOLs 😄👍

[@johndicarlo225]

That's crazy..

[@di_luka]

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 😉

[@BootedTech]

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.

[@LPgmxDan]

Volt where the mosfet was?

[@tolyanoz]

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

[@gerardoacosta5396]

Thats right he forgat to conected

[@teslasapple]

There’s no 3.3V so why bother 😅

[@David55436]

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 😃

[@markkay8117]

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.

[@n7565j]

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

[@stephenhall3515]

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.

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

[@leerzeichen1910]

Anyway, 3V3 was missing…

[@filda2005]

you dont need power button to start PC.

[@Crystalservices]

Anyways, It's taking 60 ma current immediately when connecting the power cable.

[@orion310591RS]

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.

[@Crystalservices]

May i know ,What are you doing ?

[@orion310591RS]

@@Crystalservices You ask what job I have? I cannot speak about company jobs, rules and regulations. But I can tell that laptops are toys in comparison to complex machines I work on. Industrial equipment, not consumer electronics.

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

[@xianaugustyn4931]

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?

[@SidneyCritic]

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

[@HobbyHomeWorkshop]

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

[@LPgmxDan]

Did you try to boot from USB? Maybe corrupt os or hdd you could also try booting in safe mode it worked for me for HDD data recovery but if it's still in a somewhat ok state Also could be thermals maybe change paste and clean

[@DrTech3]

[@LPgmxDan]

@@DrTech3 what you trying to install? The bios is in uefi or legacy mode? Could also be the drive if it's an MBR format and trying install newer os need to convert to GPT Any error or msg that you are getting?

[@DrTech3]

@@LPgmxDan never got any error message. Just get restart. And always getting restart when i start the OS or installing OS. But when in BIOS its not restarting.

[@LPgmxDan]

@@DrTech3 does it crash when on USB like a windows to go or live linux usb? Could be still be drive if it's new then maybe the os iso or the way you formatted the usb could also be thermals is he getting hot? I had this when PC would be ok on bios but would crash a bit after boot it was getting hot and the fan not spinning didn't help What type of storage and if an ssd's then what gen could also reseat ram

[@pp3v42_g3h]

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!

[@larrywildman4381]

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.

[@allinclusive5762]

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

[@sunnydindoyal7504]

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

[@cptrush3671]

you can buy an adjustable power supply, use the cable and tips from that. like a universal laptop power supply that has several tips.

[@Linkvolum]

Nice

[@winlose3073]

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??????

[@neshhero8416]

how can i send you a laptop?

[@Holycurative9610]

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🤣🤣

[@sumuduasiri]

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?

[@incandescentwithrage]

The customer has obviously already turned on the laptop then plugged in the power supply, how else would they know it is faulty? The damage is already done when it goes for repair.

[@khennyregdiy6102]

1)the customer already did it hundred times then whats the point 2)sorin limits the current

[@55in12]

no repair. No shortet repair 🙂
