Actually, there is no need to supply voltage to find the short circuit on the b+ line.

Which coil has a low value, there is a short circuit on that line. and generally upper mosfet or condenser with short circuit by the way, no flux is needed to remove a component
makes life alot easier often adding flux while removing. same as adding soldering while remove. so much easier. and life is about being easy. not about being a pain in the ass

Yea but this is Sorin, he doesnt care about persons who speak, but the persons which want to learn... Northridgefix will never fix laptops in a way that Sorin does, they have different approach.
@@giorgio5789 Capacitor can be used to "calm down" or filter signal. So its not too aggressive in fluctuation. He showed problem in exact component that was making unwanted short. If he did not record on video, doesnt mean he did not put another capacitor inside.
@@eugrafcmg he usually says it's just for the selling regulations, things like white noise or rectifying circuitry, I guess in the long run might show some kind of degradation in the whole equipment, but nothing stays forever...
Nice fault finding but I wonder why you didn't replace the capacitor or the thermal paste or use flux when soldering back the two MOSFETs and resistor? Do you do things like this off camera?
Thanks to your videos, I figured out that a capacitor after the first mosfet on my asus' motherboard is shorted (battery not charging, laptop not powering up with charger inserted). Thank you :) Now I'm just wondering if that could be the only flaw. Like...now that I know that that one capacitor is shorted, should I check for anything else? Or can I go ahead and try to replace the capacitor alone? The mosfets in that area of the motherboard seem to be fine. Maybe some other viewers can help? Anyway, thanks to all!
If its a bypass cap like in this situation, you can leave it off and it will function fine, check for short like he did or you can simply remove bad cap and test....
I half expected the noise AAH EEEEEEEEE from you, burnt fingers. i thought a capacitor before the first mosfet had shorted, i was wrong lol. Layer capacitors are a pain.
Salut Sorin, de curand intampin o problema cu un pc, placa de sunet reda sunetul distorsionat si infundat, mentionez ca am incercat alte drivere, am incercat si cu Linux si tot la fel reda sunetul, tind sa cred ca ceva este defect pe placa de baza. Placa este Acer Aspire m3203. Te urmaresc de ceva timp si multe din clipurile tale mi au fost folositoare . RESPECT!
Wish I can find some one like you, capable of doing this repair for me here in Colombia, sadly 2 different places said they won't do it :c Having the same issue with my Nitro 5.
Sorin, whats the consequences like now that you removed that dodgy CAP and the laptop came back to life. I mean how you suppose to know, what that CAP was suppose to do there, it's like a protection circuit that now it's not working? Maybe it's something to keep the current in that circuit more stable? All i want to know is, if the laptop is working fine without that capacitor, what it was doing there in the first place? what am i missing here? P.S. I have seen many times,that a solution is by removing a smd like this one, im not sure if you can do the same if that wasn't a cap and it was a resistor. Keep it going, you're the most real/honest/good technician on youtube.
a cap has a connection with the ground, when the cap is dead, it will be shorted to ground in most times..The function of a cap is holding the voltage a bit , some sort of fuel tank.. the reason for that cap is, smooth out and filtering the current, its limiting the "spikes". Because there are a lot of caps on each power supply, u have enough fuel left to run a laptop proper stable.. U cant remove a resistor without replacing it, your will get a open cirucuit and the laptop will not start.
Just curious what kind of cheapish hot air station you recommend for someone that is just starting out as a hobby wanting to learn this stuff for themselves? (You've probably answered this already but I missed it)

Hello Sir. I am a new subscriber to this channel and I really enjoy watching your speciality in actions! If it's not too much to ask, I have been carrying a question for many years that I don't know how to find the answer to! I don't find it on TH-cam or Google, not sure if there's any topics about my question available on the internet or I just don't know how to look for it! I had been trying to find a complete parts for any laptop brand if there's any site that can give the complete list of a laptop parts or How can I know and where do I look for to find the complete parts including the body if I want to assemble for example, HP Pavilion x360 or Asus TUF etc. basically any laptop from the ground up at home? Thx for your time.
I am curious, Sorin. Where are you from? I really love your videos and have been using the things you have taught and demonstrated to troubleshoot Chromebooks for my school!
remove the power adapter and hold the power button for exact 40 second with the help stopwatch and then connect the power adapter and press the power on button..boom🔥 this will work definitely🔥🔥
Watching this, trying to troubleshoot why my Nitro 5 N18C3 AN515-54 is having a hard time running on the AC Adaptor. At about 4 months old it started randomly dropping to 'on battery'. Went to 89% battery power and seemed to stay there for the next 10 months. Then overnight it completely discharged. I tested the adaptor and it was bad - so I replaced the adaptor. With the new adaptor, the battery indicator flips back and forth between of 'on battery' and 'charging'. It does not feel like there is a good click-connection when either the old adaptor, or the replacement, is inserted. If I put a little pressure one way or another (not consistent) on the plug into the laptop the 'charging' works for more than 1 or 2 seconds. The longest I've gotten it to 'hold' the charging status is about 20 minutes, and that was after much unplug/replug. I've seen several complaints online that are very similar to my experience. Is it possible that these laptops were shipped with bad adaptor ports? Could the bad port have contributed to the failure of my OEM AC adaptor? Unsure if the way I use this laptop is contributing to the problem. I bought it thinking it would have the necessary power. I don't do gaming, but I run a HD wide angle webcam to livestream 12 hours daily via OBS and youtube, run the laptop monitor and a secondary monitor, wired keyboard, wired mouse. Has a GeForce GTX 1650. I'm also a heavy user of internet for research - sometimes have 20 or so tabs open in the browser (Brave). I don't think any of this should cause power problems, but doing the troubleshooting, have shut down OBS and the livestream, and minimizing windows and other background apps. Doesn't seem to make much of a difference, but after 4 hours of messing with the adaptor and port this morning, have finally gotten the battery recharged to 97%. Have ordered a third adaptor, just in case its a manufacturing error that both the OEM and the replacement adapter are experiencing, but is there a way to check the adaptor port?
I had a case with an All in One Hp, computer suddenly died, after initial review, everything was ok and the charger was working properly but it wont turn back on. Later, during the day, computer worked again without modifying anything. End of story, I replaced the charger as it looses power and the computer dies after some time being on.
He is teaching us how to work without camera, the ones who doesnt want to buy it for hobby repair or simply cheap one is still expensive. He also use zippo liquid trick...
Can I ask for answer sir? Is there any issue if I will use the power adapter of my Acer nitro 5 which is 19.1v and 7.1ampere to the original power adapter 19.6v and 9.23ampere. is there any problem when using different ampere?
There is a green light(or bulb) blinking inside in the backside(botton) of laptop.I was able to notice it from the space given in the backpannel to see fans. Same Model. Is it a problem?
why is it almost always a small capacitor that makes the whole laptop fail? same thing happened to my mate vince's acer gaming laptop does acer like use low quality capacitors?
That capacitor is acting as a filter, in a more technical way of saying it's used as a way to remove the AC component of a line as much as possible. The computer will work without that filter but obviously you're sending that unfiltered power to places it shouldn't go to so that degrades the life spam of the device by a bit. That's a classic example of a "secondary component", the device will work without secondary components but the reason they exist is just to increase the life spam of the circuitry.
These machines are weird and if you open it disconnect the battery then hook up power it will then turn on there's a safety chip in the battery that makes them DOA
Mr sorin could you help me, i have a laptop but the screen is flickering, i have tried several methods starting from checking the cable, cleaning the pcb screen and heating the pcb but it doesn't work, could you give me some advice what i must to do?

Good job Sorin. Themal camera will help than the use of finger feel in detecting which components gets hot on the board due to short circuit.
Sorin saves yet another electronic device from the landfill. Nice!!
We don't live long. And time is the most important thing we have but I can say watching these videos was worth it.
Actually, there is no need to supply voltage to find the short circuit on the b+ line.
The red probe is on the b+ line and the other black probe is in contact with the coils. multimeter should be in ohm range. Which coil has a low value, there is a short circuit on that line. and generally upper mosfet or condenser with short circuit
by the way, no flux is needed to remove a component
makes life alot easier often adding flux while removing. same as adding soldering while remove. so much easier. and life is about being easy. not about being a pain in the ass
@@klaasj7808 more convenient when soldering flux. smd capacitor removal time there is no difference between flux and time without flux

Nice and quick troubleshooting sir, how about the caps u removed, it needs a replacement or not because I didn't see un replaced it a new one?
Caps are like fuel tanks: there is always more.
