You are the best repairer. Yesterday, I tested a capacitor with a buzzer, but I forgot to unplug the charger, and it explode right in my face."

That's one lucky customer.. Rather unfortunate that the company refused to spot the problem.. Maybe Acer can hire you for further repairs 😅

Reading the client's letter and putting yourself in their shoes is humbling...that client was lucky to get in touch with Sorin (sobering process). All the best.

Manufacturers don't want customers to be able to fix their stuff. Lucky we have Sorin!

People like you make a loooot of people happy. An honorable profession! Thank you Sorin!! 👋👋☺

Just goes to show - experience and skill makes all the difference. I bet it was a good feeling getting this one working again. Another instance of how a shorted cap can cause weird things to happen.

I'd say the manufacturer didn't even bother diagnosing as it's not economical for them to do so. Is that a wasteful practice, yes in my opinion it is, but from their (manufacturers) perspective they can't and wont generate any revenue unless they force the owner to buy a replacement MB or entire new laptop. It's what keeps this fake economy going. If anyone of you are old enough to remember prior to 1924, the average lifespan of a light bulb was around 2,500 - 3,000 hours, heck the Centennial Light Bulb is still burning today and it was first installed back in 1901. Anywho, in December 1924, a global organization known as the Phoebus Cartel hatched a secret plan to increase sales by bringing the average bulb's lifespan down to just 1,000 hours. This began one of the first known examples of planned obsolescence. This hasn't changed to this day, in fact if you pay attention all electronic devices die after the warranty expires. It's not a coincidence, its planned so they can sell you new sh*t! Anyway, nice work Sorin, good job mate.

Great video (as always) and amazing to see you solving all the challenges that come up in such an "easy" way! Thanks for sharing 👍

Teacher you make these videos so enjoyable ! Thank you again for another lesson. God bless you!

sorin, you’re very smart to find the simple problem so quickly. manufacturer should have either repaired (or replaced laptop) under warranty given just outside warranty period (one yr warranty presumably). ones risk buying expensive laptop!

Wow.....genius Sorin. Thank you.

Sorin you legend I do find your repair videos relaxing keep up the good work you do :)

Hi Sorin, great video. What would be really useful is a video just explaining the resistance expected on shorted CPU's, GPU's and video ram chips.

C-mom Sorin, you know why they didn’t diagnose the problem, because the mainboard is about 750$. They make about 500$ on it or more by replacing it. Or they get the customer to buy another laptop. Either wait they make big money on the situation. Thank God for shops like yours! I just wish I could ship my Acer Nitro5 to you , but I’m in California USA 😢 and the local shops to me want 250-300$ to fix and 100$ for just diagnosis and shipping etc. My late mothers laptop. Just died one day. Cost her 650$ used, and she never even gamed on it. Just internet browsing paying bills. Hope one day I can figure out the problem and bring it back to life . Mainly for the sentimental reasons.

So what I did, decades ago, having the same problem with my daughter's computer, at the time it was not laptops, but a big box with Win 98, knowing nothing about, I brought a book about computers, and learned. Then The first laptop I repaired I had it in pieces in a trash, with power connector having burned the mother board. Also I had built three computers before for me and my two daughters, and repaired some others for my students at school in my classroom. Sorin is the channel I chosen to learn more about laptops, you can go to other and older videos explaining other issues that can have happened on your mother's computer. In my experiment, it's rare that a computer is totally unrepairable when everything is clean on the motherboard. So opening it gives you a look to some basic things, clean, verify screen, battery, keyboard, power connectors, liquid damage, temperature sensor, buttons, SD card reader broken, power button... And after , shorts, power not present, are also basic things, I learned with Sorin , and I love how he explain things, and also the idea of saving the machine from death😺

Really good work man

I did a test... I added caps on a motherboard where ever I found a place to put. Before and after. Bench mark .. cpu performance was 2.4% greater. Mofets temp was down by 1 degree. Cpu temp down also 1 degree . .. I removed the caps and tested 5 times. And the result was the same more caps seemed to improve slightly. Strange to me . Seems like less ripple on coils.

Thank you for this I was able to fix it. You're the best!

Sorin saves another one from the landfill. Awesome!

Working thru the problems to manage a working unit for delivery back to a customer. Thank you Soren for a nice lesson, and where as a beginner at repair, I was always curious as to the ribbon cables to their plug in connector....would I damage or not reach secure connection? Also, where dust might be causing fan and overheat issue by blocked air flow? As for the manufacture, there seems to be a huge disconnect as product to any repair. Across the price range of units. At my workshop, I seem to be mostly at repair of cars. Key problems, mechanical repair as failed parts. But so often, solder repair is a required need to electronics. Chance stuff like a bit of metal dropping into the cigarette lighter and causing a huge short with melted wires, internal to the dash. A metal bit from a dash cam power 12v plug in. Stuff like a drop or two of coffee that was a spill to a fire wire cord end. I really enjoy the various problems that can be solved and the interesting review of devices. *Washington State, US. M.

Good work!

It's the same with mechanics, doctors, elec repairs, etc, ie, they might have a sign, but you don't know their skill level. It's why all the mechanics came to us for the hard stuff, because we were an auto engineering machine shop.

nicely done

A lot of people are unaware of the Sale of Goods act, items that cost over a certain amount are expected to last a lot longer than 18 months

Merhaba arıza bulma ve onarım yeteneğiz mükemmel elinize sağlık

As a Sony and B&O trained engineer i often despair at the lack of fault finding skills of some manufacturers service tech's. They must cause a lot of customers to avoid buying that brand again when an expensive item is declared unrepairable just after the warranty expires and the fault is just a shorted component that can be be found very easily. Perhaps Sorin needs to offer them some training in how to find a shorted capacitor. This customer is lucky to have an experienced tech that knows how to fault find.

All laptop service centers for manufacturers are not doing mainboard repairs, they deem it defective and move to the next one. My laptop died after 2.5 years and i couldn't find a decent repair shop in Romania to fix it. This was my first laptop and because of this bad experience i will not buy a laptop ever again. I will invest my money in a pc.

idk why i am happy when laptop goes on

Sorin, the videos on your channel are excellent. Can you rank laptop brands based on the number of malfunctions? And it seems that there are a very high number of malfunctions with Acer! Because there are about 10 videos where we see the Acer Nitro 5 model. I think the reason for the high rate of Acer laptop malfunctions is the lack of quality components. Gaming laptops have higher power supply and these motherboards may not have the capability to handle so much energy!

A lot of humor in this video...😂

Don't subestimate the fact of using thermal camera specially when you are working with high end notebooks, where temperature is critical. If you don't have a clue where the problem is and try to find the hot capacitor using any other older way, you'll start the motherboard and in few seconds many things will be hot, making thing more difficult.

It costs money to fix warranty work and some companies refuse to do it - labor and the cost of parts - they will fight it - there's something the companies don't think about is I won't buy from that company again

hahaha "I am excited to investigate this mystery"

I'm an engineer at Acer and I can confirm that the second fault was caused by you not replacing the capacitor.

Why did the manufacturer not diagnose and repair the laptop? "It's not in their interest to do so, they just want to sell you a replacement motherboard OR a new laptop if it's outside of warranty period", very dodgy manufacturers.

looks simple because you are simply a genius?!? probably ;)

I have the same laptop that has no power. It went out and it was done.. Wish mine could be fixed..

My friend have same laptop. First time it blown whole track. Repaired track soldered caps changed first DC in MOSFET because short destroyed it. Laptop worked fine for 2 months after it friend came again laptop dead. There are four columns of three caps next to each other. I looked at these caps another blown in different column. Repaired replaced MOSFET and after a month again 😂 insane and again cap in this area 😂 I replaced all caps there 12 caps and laptop is working ever since insane.

Repairing electronics is very satisfying for me but i'm wondering... What's happening with every manufacturer? Failing capacitors, transistors, integrated circuits, you name it... Thankfully i can repair my own stuff, otherwise i don't know how many hundreds of dollars worth of electronics i would have thrown in the garbage, but what about everyone else? Manufacturers need to stop disrespecting customers like that and should design stuff with proper components, not garbage designed to fail in a couple months. And i say this even if the repairs bring me money, it just isn't right.

It's not really guessing, you can get there by logic. Like in this instance, if you see that the 19V power rail is shorted, you can THEORETICALLY put up to 19 in there, assuming nothing else is blown down the board, but that's not a good idea, because it's not necessary. If something more is wrong in the board and you accidentally send 19v to the CPU, I think you can guess what will happen. At least you will see some funny smoke. What he does here is to inject a really low voltage into the rail, you can actually do it everywhere on that same rail, doesn't matter if it's the current resistor or one of the caps across the board. Of course you want to do it after the mosfets because, assuming they are doing their job, they will cut the power if they detect a short and you know, you actually use this technique to find shorts so it would be pointless. The key here is to use current instead. You limit it, ideally you will use only the amount that you need, and different parts of the board will have different tollerances, but just make sure to use enough to spot the hot point without burning the layer of the board and you will be good to go.

One thing beats my imagination. An HP Laptop Goes off by itself and never woke up. All the necessary voltages were present. No heat is coming from anywhere and still the laptop will not turn on.

Hey man, I hope you'll see this because my Acer nitro 5, 12th gen which I bought a few months back, suddenly turned off. The charging indicator isn't making any light when plugged in, I have tried every troubleshoot and fixes on the internet, but to no avail, my laptop was still dead as a plastic.... What do you think is the problem? This is the first that I'm experiencing this and I'm crying because it's the only device that I'll be using for work, and without it I'm useless as an earthworm

Hi Sorin, I did a stupid thing last week to my Acer Nitro5. I was working with stepper motors and an Arduino stepper motor shield connected to a USB port, and inserted one of the stepper driver boards in the wrong way around, as soon as I turned on my bench power supply to the motor shield my laptop died instantly, I had sent 25v at 3A down the enable pin of the driver into the USB port😥. The laptop would not turn on again, the bios tries to boot it but can't. I could not be without a laptop so bought a new Nitro 5. I would like to try and repair it do you have any suggestion's to point me in the right direction for diagnosing the problem. I am reasonably competent at electronics to the level of designing and manufacturing my own circuit boards, but as for diagnosing failed laptops my knowledge is limited. I would appreciate any advice you can offer me. Keep up with your videos, they are helping me to advance my knowledge of electronics. Thanks.
