i took 6 out of a dell laptop and it worked fine 2 years ago my stepdaughter still uses it to this day she had it sitting on bed got too hot because laptops are bad about airflow i removed 6 before it decided to come now granted im not an expert but was going to put the others back but oh well it worked fine there was like 8 of them in a row on back side of board like what are you doing dell? lmao.
Easy fix if you have a thermal camera I guess. Nice quick one Sorin! You are going to get a lot of hate if you don't replace cap's. I guess you can at least say "I'll replace the cap" with your sly smile the viewers like me will understand :)
What temp you use as you leave the board in case ? Are not worried to damage screen ? Just curious as i'm still removing motherboard from chasi (but i'm only hobbiest :) )
This concerned me too. OLED displays are easily damaged by heat, so if this was my repair I'd use hot tweezers to minimize the chance of damage. Another option would be to open the laptop and have the screen over the edge of the bench.
Hey man i have a question I heard rumors about zenbook series having problems with their usb3 chargers and using laptop while changing causes dmg to motherboard because of faulty capacitors or something Do you have any opinions on this?
Thanks a lot for sharing Sorin. Why you wanted to find out the polarity in the caps? (just right before checking with the thermal camera). Also how would you proceed if you had had no thermal camera?
You need to inject the current on the +ve rail so that the faulty component gets hot. Injecting on the ground would not send current through the board - it is a pointless exercise. With no thermal camera, you can feel around with your fingers for a hot component/area, and then use a volatile liquid like isopropyl alcohol (IPA) (or Sorin's favourite is lighter fluid/petrol) to see which component evaporates the liquid first.
how do you charge the customer? I mean, here in Brazil, the price for the repair uselly is about 40% the value of the motherboard (we use aliexpress to compare the prices). For you, the price is unique no matter how expansive the laptop is?
Hi everyone. Quick question for anyone who can answer. Should every laptop CPU have a resistance of 70ohms on the coils? As Sorin was saying even 60ohms can indicate a dead CPU. Much appreciated to anyone who answers.
Good day, teacher. I am experiencing the same issue with my laptop. Is it possible for you to assist me with the repair? Could you please provide me with the appropriate contact information to initiate the process?
Because standard engineering designs and component specifications require it. But specifications have a tolerance and manufacturers put more capacitors there to allow for variations in performance of individual components and tolerances. There are many more capacitors than the minimum required and that is why removing a few caps won't make any difference. But bear in mind these caps are all on the power rails. If you remove a cap that is part of a functioning circuit the circuit will stop working. You need to analyse the circuit to know if the cap can be removed or not. But generally a few caps on power rails can be removed without affecting anything.
This Laptop will return soon. The second capacitor does not look healthy either. if you look closely, it looks like a dent in it's center. ruclips.net/video/71JAsL1-IkQ/видео.html
Very good and quick. Next laptop you cannot use your usual tools. You must use only a coat hanger, a piece of gum, and a pencil sharpener to fix next problem. Challenge accepted?
@Equatis You need to replace the motherboard. Sucks. Even a simple thing like a usb-c damaged port. No explanation from Asus on why it stops working. Mines was also just over 2 years old. Approximately £200 repair.
I have to say Watching you teach Diana is awesome. Best training videos I have ever seen.
Thanks for the explanation about capacitors👍👌
sorin you are the assasins of the capacitors.
Why this repair content is so wholesome😂
Thanks,appreciate you.
Thanks man!
Sorin, please make video on What happens if remove all capacitors from motherboard one by one. Will it still work normally???
What is the limit?
i took 6 out of a dell laptop and it worked fine 2 years ago my stepdaughter still uses it to this day she had it sitting on bed got too hot because laptops are bad about airflow i removed 6 before it decided to come now granted im not an expert but was going to put the others back but oh well it worked fine there was like 8 of them in a row on back side of board like what are you doing dell? lmao.
so two was left bigger ones good enough it worked fine so no telling how many you can remove before it becomes a problem
Asslam-o-Alikum . I am from Pakistan . I am biggest fan of your work.
I love watching this channel
Louis Rossmans repair videos were better :-)
Always pleasent sensations with an easy job like this :)
Very, very lucky customer indeed!
amazing !!!!!!!! what a lucky customer! GG Sorin
Asteptam cafeluța! Duminică placută tuturor !🎉
Brilliant as always but surely that capacitor was there for a reason or Asus would not have fitted it ?
Looks like an extree ,lol
some capacitor are like politicians, many of them are surplus because they go bad often...

I see, i planed next week a video about what the capacitors are doing and why they are there, hopefully i will clear this
Hello, great vid! Do you think it is possible to replace the mobo on this laptop? Thanks
If it was designed to have the capacitor, why not replace it?
If he dont put cap it wont fail again. Giga brain move😅
iT'S WORKING.. Love when you say it🥰🥰🥰🥰
Nice video! How did the laptop work without replacing the capacitor?
Because that cap is used as a energy storage. There are many others nearby, one less make no difference.
@@DumahBrazorf wow that's interesting. Learnt something new. Thank you.
@@DumahBrazorf Hello, capacitors on power rails are used to minimize spikes and keep the voltage as stable as possible. They are not used for storage.
@@markkay8117 Indeed, EMC compliance as well.
Hey Sorin, please replace a new capacitor 😂
off camera 😂
Just pull the one next to it, measure it and replace with similar
Here we have an insane laptop🙂
Since you remove capacitors quite often, do you think investing in those tweezer soldering iron would help?
Not rplacing capacitor is also a talent...others are afraid to take that risk...love u sir
That's because removing components increases noise/ripple on the track, and strains/reduces the lifespan of remaining components.
Still waiting for a good T-shirt with the motto.

Hi Sorin could you do a live stream repair?
Hey man i have a question
I heard rumors about zenbook series having problems with their usb3 chargers and using laptop while changing causes dmg to motherboard because of faulty capacitors or something
Do you have any opinions on this?
Can confirm
You know what to test
Thanks a lot for sharing Sorin.

Thank you @@ijaygee1 !
Why they use capactitors in these laptops?
What is the name of the thermal microscope you use?
I'm confused, I thought you said you can't diagnose a laptop with an ohm meter, or is it just the dead CPU checking?
how do you charge the customer? I mean, here in Brazil, the price for the repair uselly is about 40% the value of the motherboard (we use aliexpress to compare the prices). For you, the price is unique no matter how expansive the laptop is?
good question, sadly no answer, always curious about how much those youtubers are really willing to help.
Nice one
some capacitor are like politicians, many of them are surplus because they go bad often...
Lol 😅😅😂
Good morning sir
morning?
@@preytecmorning in the UK, yes. 😜

No, depends on the cpu type and generation, actually most of the cpu have around 3-6 ohms
thank you so much@@electronicsrepairschool
Was this brand new?
Good day, teacher. I am experiencing the same issue with my laptop. Is it possible for you to assist me with the repair? Could you please provide me with the appropriate contact information to initiate the process?
"Finally, I fix something today" 👁👁
Is it ur first repair?
How much do you charge for this kind of job? BR, and do the good job
9:32 - Yes we know what you mean :D
This is the proper way for nice laptops 😂😂
6:32 blown-out capacitor
👍👍👍
Haha, Now the Laptop´s not more "A Nice" Laptop, NOO, it´s "a Insane" Laptop! YOU the BEST!! Lovely...😂🖖👋
If that cap was unnecessary, why put it in there at all?
Because standard engineering designs and component specifications require it. But specifications have a tolerance and manufacturers put more capacitors there to allow for variations in performance of individual components and tolerances. There are many more capacitors than the minimum required and that is why removing a few caps won't make any difference. But bear in mind these caps are all on the power rails.

@@g4z-kb7ct Thanks for the input. I appreciate it.
👌👌👍👍
LOL. A M3 Pro laptop spec-ed to normal PC levels of RAM and SSD costs $7K.
No capacitor no more short 😂😂😂😂😂

❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤
Hello🤝👍👍👍👍👍👍👏👏👏👏👏👏👋👋👋👋👋
65 C in idle for CPU, not goood...
c'mon dude, think....the back is removed so there's no forced airflow. With the back cover on the fans and airflow is better....
No capacitor no shorted capacitor 😂😂 it’s that simple 😅
Very good and quick. Next laptop you cannot use your usual tools. You must use only a coat hanger, a piece of gum, and a pencil sharpener to fix next problem. Challenge accepted?
Horrendous laptop
My wife has this same laptop and we're experiencing same symptoms. Only two years old. Done with ASUS.

This is a lucky ducky. Salute 🫡
