[@tunkunrunk]

people have to make their own researches on the internet . I say that because I started learning electronics to fix stuffs one year ago , and the majority of videos , even books teaching you the main components widely used , is incomplete , and to make things harder , some components , especially the smd type , look alike , this very confusing at first . As an exemple , smd resistors look physically like some smd fuse , smd inductors . Not to mention inductors that have a large variety of shape and size . The best way to learn them is by trying to fix a large variety of electronic devices ,and when you encounter unknown components , search them on the internet and write them somewhere to create your own electronic components data base

[@etg9080]

why only left to professionals, as far as you have understanding what you are doing and have tools to perform, it is not that difficult. the person can easily figure it out by reading the writing on the component.. for example for the inductor on this video written as PL and L stand for inductor.

Removing COUPLING capacitor will not pass without problems.

Why did you not replace it with proper inductor or run burn-in with GPU benchmark for 2 hours to assure no other system stability issues?

[@d614gakadoug9]

He _does_ have the problem that he has no idea what sort of inductor was there originally. But yes, he did a very crude hack and concluded it was OK. He does that sort of thing a lot. The inductor was probably a "ferrite bead" designed to be lossy (like a resistor) at high frequency and used to meet EMI/RFI standards. It might also have been important for signal integrity. He's been known to take out a bunch of ceramic caps there at least in part for the same reason and just state completely without evidence that the board would still meet standards.

[@jozsiolah1435]

I found a very good fix, without disassembly. By running the laptop on battery, writing some lines in word pad or notepad, and not using any other application. Some desktop renaming, file explorer, starting the Start menu, and offline. The fan speed informs, how the fix is working, the aim is to reach min fan speed using each power plan, with max settings. The fan speed must be min through the whole drain. The cpu has to be set to 0% at min, 100 for max. Balanced mode balances the battery, each cell has to be evenly warm, the battery electronic panel hot. After the fix is done, the cool laptop can be used for gaming forever, with just one battery pack. The battery doesn’t have to be in the laptop after the fix.

[@n.gineer8102]

First thing i thought was the owner didn’t know what a cap looked like, especially if its burned. Maybe the inductor was going to fail anyway and this guy just got unlucky or something shorted since the case had been opened to put in the SSD.

[@Muhendisbeyy]

Evet, sanırım o indüktör patladı, pedlere yakından bakarsanız, siyah bir kurum fark edeceksiniz, tüm videolarınız için teşekkür ederim Sorin ve devam edin.

Oh I see, I was going to say what you do with a bad cap? but now I understand why you said it.

[@LeonardNyika]

This is great ❤

[@demostenesramos]

Probably owner shorted his screw of that inductor with the plugue case beside, same way Sorin touched the "wire/proper calibrated" fuse to power plugue shell and it burned.

[@Barbarapape]

A little knowledge can be a dangerous thing. Before the days of surface mounted components it was easy to tell just what a component was just by it's appearance, but today unless they have markings on them or on the pcb they all look the same. So unless you have the experience as Sorin has, don't remove anything. Not even a "Calibrated Fuse"!🤣

[@winlose3073]

I think he meant the laptop stopped working and he just chose to check and he thought he found a short. Maybe what he meant by blown is shorted cap but it's not a cap. Still does not explain why the lap stopped working!

[@geovani60624]

the inductor fried and opened, he thought it was a shorted cap and just removed it but yeah, it didn't change anything

[@abiosamlinkchannel]

Please I need you contact

[@David5467]

Hi Sorin Do you still have that laptop at the shop? have a look at your video at 5.12 the pad looks loose. maybe that is why the inductor looked burnt from a bad connection.

[@salvamipc]

I think he removed the battery to install the ssd, on the next boot takes longer to boot because its load the kbc rom, so he panic and removed the inductor.

[@drEvilfromLV]

PCB shows burn marks/soot, and one of the pads actually seemed to have a velded piece of component in the middle. So some sort of event did occur. In my younger days a short between adjacent windings in power transformers was a thing (due to poor quality of insulating enamel), causing the whole transformer to burn. S ince this is a high power circuit in laptop terms, by any chance such a short happened in the coil here? Might go unnoticed for long time if power supply is connected permanently and esp PC is on all the time, or the burn effect may take time (multiple power cycles) to develop into a catastrophic event..

[@jxmai7687]

Yes, that was what I thinking, most Acer bios will restart 2-3 time to detect the hardware, detect the OS, then save the setting.

[@jxmai7687]

@@drEvilfromLV the burn marks mostly just reset the bios, with the battery should still be able to turn on but until he paly around and lost all the battery power.

[@FixDaily]

Because these Win10 or Win11 systems sometimes don't show anything on screen for awhile while booting. So no feedback leads to the thinking that the computer is faulty

[@etg9080]

Good video but as far as anyone has better understanding what is doing and have tools to perform, it is not that difficult. The customer can easily figure it out which component was blown up by reading the writing on the beside o;n the component on the motherboard..

[@corel965]

[@gerhardpetersen]

If a capacitor blew but was not shorted afterwards, removing it would don absolutely nothing...... Something caused the inductor to blow, the black mark on the board shows that. The laptop then stopped working, but removal of the blown inductor would of course do nothing. Now that it's working, need to know if the owner took out the SSD which appears to have caused the fault or if that was just a coincidence.

[@vs68s39]

was the inductot required for buck/boost power supply. why did the circuit still work with a low inductance wire???

[@MykolaInc]

If there are no pulsating current on one of the sides of the inductor it's probably just a filter (the same purpose as bypass capacitor) and could be more or less safely replaced by a wire.

[@d614gakadoug9]

It it was like the other small inductors shown it was almost certainly a "ferrite bead." These are usually just a straight conductor passing through a small piece of ferrite and used to suppress very high frequency noise currents. They actually behave more like a resistance than an inductance at high frequency so that the energy is converted to heat. In any case any package that would fit on those pods would be far, far to small to have useful inductance for energy storage as in a switching converter.

[@michaelgleason4791]

We all have to start somewhere.

[@SerenoOunce]

No reason can't have both a PCF *and* and replace the inductor. Install them in series.

[@Mnelissen1968]

Inductors conserve current by storing energy in a magnetic field, whereas capacitors preserve voltage by storing energy in an electric field. Please explain why replacing an inductor with a "fuse" works? Since most inductors are low in resistance, doing so are you not changing the purpose of that specific circuit?

[@leerzeichen1910]

I really wanna know how much current that „proper calibrated fuse“ can handle? Just for my curiosity :)

[@frankmormando3917]

Thank you for the explanation at the end. I remember you saying an inductor is a wire, so what you did is definitely a safer option,… excellent work Sorin

[@d614gakadoug9]

There is zero reason to believe that what he did is "a safer option." The inductor that was there originally might have fused at less than 1 ampere while the wire would probably hold up just fine for quite some time at at least 5 amperes.

Well, if the customers story is accurate it would suggest the inductor had burnt out (open circuit). That makes sense of your fix.
