Im running a big IT Company, we do motherboards repair, the whole company started because of you, i learnt from you, you made it so simple for me, bro im telling you, im the best now because if you, Im from South Africa. The whole city they respect me but they dont know that i learnt from you. Today i did a video repairing a board, i mentioned your name Sorin and your youtube Channel. Hope you will see my videos, and my channel. JBV COMPUTERS. Salute man, im developing my UA-cam channel, im still trying to find good quality cameras
Mr Sorin, pls never ever remove a pwm ic n plug in charger ever it will result in 19v getting to 3v / 5v rails which will result in catastrophie. That burnt ic produces the ldos, n the 3.3,5v alws.
As I'm getting older I get upset for longer every time I fail to repair something. Is it my lack of knowledge or an unrepairable device? This is a good reminder that sometimes you just can't. Thanks Sorin
I think its really important to show the non fixable ones. Reason being is that you can show what to look for in a situation like this so that those learning from you do not end up wasting their time. There are very few videos that discuss troubleshooting the PCH/Processor/Video chipsets as to whether the problem lies with them or elsewhere. So, This is really important to watch. I, For one, Would love to see more videos on the chipset and processor / video chip circuits. Specifically the Vcore rail failures and trouble shooting. Thank you for such a good video.
Great video Sorin! It's good to see the diagnosing process step by step and get all the way down to the chipset. At which point it's just too expensive to repair instead of getting a new board.
Bogdan RUSU hey Bogdan You want to lighten up a bit it’s a standing joke with Sorin he never gets the cloth out unless it’s an apple And yes I do listen and yes I do watch Sorin all the time and yes he’s better then most on UA-cam
Sorry for that fellow but this was a great learning tool.. I know I learned from it.. thanks Sorin And if it makes you feel any better I have fixed two laptops just from the knowledge you have shared here on your you tube channel... carry on my friend!
It's good to see that you try and also that you indicate from what point you deside to give up. Which is also important to know/learn that. So, thank you for posting the video anyway.
Like always a great video Sorin. We learn a lot from your videos, but this one, believe me, we learned much more then any others videos with successful fix. Please carry on uploading nice videos, even fail fix ones. God bless you
I think that is the 3 pin diod connected with vreg 3 and also connected with cmos battery with help of one resistor..and output side connected with processor (chip)...that called RTC..supply..its first supply in always available for prosesor..rtc is most important supply for power on the laptop board...and also thanx for the sharing ur experience..i always learn something with your videos..thanx again..
Good evening all, Best Laptop repairer, knowledge provider on UA-cam and it is free not £9,520 a year + interest. Thank you professor. The USB thingy I believe is called USB KILLER, it kills immediately any device plugged to through USB port.
Hey thanks for the Learning lesson on your video I think you did all you could for this little board there's a time when we have to say stop it's not worth it when I used to do TVs and repair VCRs sometimes you just have to call it and just replace the board are the power supply people on here get all excited like they know everything I'm sorry folks this man knows more than most techs out there do
I use a Thinkpad T420 from 2011 and i really like it. It's 9 years old but it's still fast even with WIndows 10. On Ubuntu 20 it absolutely flies. It's a Lenovo product but it has my recomendation.
I had a Chief Engineer that once told me, ‘that’s going to want mending with a new one.’ If Sorin can’t fix it then it really is FUBAR; he calls it like it is. 100% genuine thought process.
It's ok Sorin, im learning a lot from you! tracing and finding the problem from an expert like you. Thermal camera saves you time, yes, but analyzing and solving the problem is what i think make this channel its title, Electronic Repair School. I know you can repair that laptop, but it will require more time and the components to fix it. (Y) (Y)
" You can't win em all " When i used to repair peoples analog devices, i could get 80-93% working but the rest was deader than a dinosaw. I had to learn that some things could not be fixed and getting upset was a waste of time.
Salut Sorin, din ce am vazut in materialul tau video cu referire la CPU cum ca nu se mai poate repara, tind sa cred ca mai ezista o solutie, acum ceva ani am intalnit si eu o problema asemanatoare si eram pe punctul de-a renunta insa ce am facut. Am dat procesoru jos de pe placa si am incercat o rebilare dupa care l-am sudat inapoi, intradevar nu a functionat, insa am luat o placa defecta am dezlipit procesoru de pe ea si l-am atasat pe placa cu pricina dupa o rebilare corespunzatoare si vreau sa iti spun ca, lapto-ul a pornit fara nici un fel de problema, pentru astfel de operatiuni nu folosesc statia cu aer cald deoarece pot distruge mai mult cipul si am preferat sa folosesc o statie IRDA Infrared. Mult succes
Thanks, I mistook the chipset for the integrated gpu. I now understand why there was no display from my asus gaming laptop even though it has a separate gpu chip. I think the chipset was running so hot that its outer shell cracked and inside of the chip was redhot when connected to power.
The integrated GPU is inside the CPU die - the long rectangle die on the CPU package -. Sometimes the PCH explodes randomly or as a result of something wrong happening on USB as well.
I've spent hours watching this channel and what options we can take when a diode forced a system to stop working, or a mosfet needs a jumper instead of replacing, or how to make a liquid flux, etc! Now I have an issue with an HP Z240 tower workstation, it won't start but when plugged in, the white LED blinks 2x every 2 seconds and won't stop (until unplugged) I guess its time I try one of your fixes/method of checking with my multimeter but I don't have the schematics of this system. Perhaps you can point me to the right direction, thanks.
I dunno, I always thought the same so I bought a nice expensive fancy flir. Ended up never using it so I sold it and bought little cheap flir c2 to have just in case but still never use it.
if the CPU is getting hot without anything else getting hot and the laptop doesn't POST (black screen but keyboard light up and voltages around the motherboard are present ) is it gone 100% or i could have missed something?
Thanks for the video! I saw some people challenging the use of "petrol" for heat detection. Some lighters use Butane and others Naphtha. Is it Naphtha that you are using?
One question. Is the processor hard coded to this motherboard and with the bios on this motherboard and thats the reason why it cant be fixed or it could be fixed but there is nowhere to find the processor (like ebay aliexpress etc)?. For example in iphones a dead proc is game over but dont know if it applies in this case as well.
so many damages.the earphone of the laptop short because they plug the output of speaker of the subwoofer so alternating current enters the whole motherboard so that all is shorted
Sad to see that it cant be repaired but replacing the board would prob cost more than buying a new laptop , i repair laptops too but i dont have the right tools like you have i just check the boards for burns or cracks ,i clean them up before trying them and making sure the connectors are in place, some mother boards wont power on if the wrong memories are in , check the battery and chargers and cpu for cleaning and repaste , when i had to repair my sisters laptop Acer the board had blown and cost £66 for a new one maybe worth buying it but not for one over £100 or more!
Sorin, Did you try ones to replace the chipsets. You have so much skills with hot air. If the chip is cheap try it I will say. Greetings from Nederland
Chipset is cheap. 10-20€ but he should use a pre heat station. I bought one myself for 100€ this week to replace PCHs. But before throw it in the bin he could try to do it without a pre heater.
overvoltage... change processor, change chips. seems like a mini lightning strike. like when your aerial radio antenna get struck by lightning, better buy a new radio instead.
Very nice and interesting video. But if each power line would be protected by a diode, wouldnt it be an easy fix? I am asking because I remember that you dont like these protection diodes.
Some laptops have TVS diodes on the USB data lines, some don't. Unfortunately even with TVS diodes other components can die as well. It's a good measure but it's not a full protection. A power switch with OCP for power lines and an optoisolator for the data lines would protect better, but it's not practically and economically viable to put them everywhere. Some laptops do use a power switch with OCP, but I haven't seen optoisolation on laptops yet as it makes little sense, they are rather used in some industrial equipment.
Hi, Thanks for explain Do you have any video about how to change the screen Asus UX301L NotebookPC,outside glass fine but inside is broken if do you have any video please let me know.Thanks
i have a genuine question which i think could be resolved by a replacement super io (ITE IT8587E). It is getting hot the moment power is applied. Is this a sign that this needs to be replaced by an expert.
Morning sir,I have issue with a Samsung note book motherboard.the laptop is charging but not powering, 3.3v is present in the bios and super i/o but it is not present in the power button.pls tell me what to do.thanks
Take a continuity tester. Trace the path from the button to the embedded controller. - Is the button connected via a flat cable? Sometimes the connection here is faulty. Mostly because the cable has broken lamells. You can (only for testing) short the contact on the mainboard (the on that goes to the button) to ground. Does the mainboard start then?
USB Killer will kill the PCH for sure. It could be a powered usb with a defect too. I have a bad PCH with shorted data lines for repair here too right now. But switching the PCH isn’t trivial... I ordered the chip and will try it anyway 😎
That's one of the reasons I hate embedded CPU - you can't change the CPU - that's the reason is you have to buy a new motherboard and the manufacturing is cheaper - but that's the way it goes - the manufacturer says they are making both - a socket one and embedded ??????? - maybe someday somebody will find a way to replace an embedded CPU
Sorry but isn't the chipset replaceable ? also everything is repairable if you consider (fixing - changing - exchanging the whole motherboard but keep CPU gpu RAM HDD etc..)
Learn something with electronics. I do the same job and I learned a profession that's called "Energieelektroniker" here in germany, more than 30 jears ago. The rest was self teaching. If you have a brain and you can think, and if you know something about electronics, then you can do all that. But it needs some years of practice to become really good (in my case). Today it needs less time, because we have UA-cam now! The time was never better for fast learning results. I wish you luck!
The PCH died as a result of the event that happened on the USB port, not from the customer trying to fix it. But it's true that in general someone trying to fix a machine without knowledge and experience can make it worse. That's how you actually get experience though.
This laptop was doomed from the beginning. Replacing a PCH isn’t easy. But what I learned while repairing motherboards is to check the usb data lines and HDD plugs for shorts. If there any most likely the PCH is defect. Second is BIOS corrupted followed by I/O shorted somewhere.
Sorry my poor english How mucho cost a laptop like that? Here in Argentina its like 1000 usd my question Is how mucho do you price a mother repair.. 100 usd 200 usd? I was told that people in usa drops devices working fine just because a new one has been boughten Here we cant buy new ones people earns like 300 usd at month but there un your country earning 4000 ah month does really people repair devices? Plz someone leave a repply ill be so much greatfull
with motherboard like this one with almost everything integrated/solder on board price will be probably somewhere near working used one. Best way from here is to sold screen and case on ebay, maybe SSD's depend of model and just buy something else.

@@lukedavis436 I rarely have use for notebooks and even when I need one my old EliteBook 8460p is still up to the task. Thinking about buying something newer a year back but to get something similar (but obviously newer, better and faster and lighter) I need to spend much more than I'm willing to give on something uses almost never. And for less money I can get one of these plastic-fantastic toys with hinges waiting to break from a breeze. I think I'll maybe just put bigger SSD in this one, it came with 128GB but MS have mission to make windows folder about that size in near future.

not about money it's even not worth to spend it on fix it .the best choice is replacing the whole board for honesty and Peace of mind both customer and the technician
Sir, I need your advice please. my new laptop stopped to output 4K resolution to TV ("no signal") when I switch to FHD resolution it's fine. it's worked fine at 4K until before 2 weeks, its a new laptop (only 2 months) I tested 10 HDMI 2.0 cables, few TV's, and reinstalled drivers and windows. could this symptom indicate a malfunction in the HDMI port? Video of the problem: ua-cam.com/video/T6DQgIZD1ng/v-deo.html Im not sure if they will replace the port, or just replace the whole motherboard

I blew up that chip, when I have removed the LCD ribbon cable.

Super I/O shouldn’t got hot (over 40c). Must be replaced.
did he plug in one of those fake USB sticks that put out a sudden 110v to the usb? That is alot of damage for just a sparking USB.....

This probably would have been a fixable job, if the customer didn’t try to fix it.
The PCH died as a result of the event that happened on the USB port, not from the customer trying to fix it. But it's true that in general someone trying to fix a machine without knowledge and experience can make it worse. That's how you actually get experience though.

But what I learned while repairing motherboards is to check the usb data lines and HDD plugs for shorts. If there any most likely the PCH is defect.
Second is BIOS corrupted followed by I/O shorted somewhere.

@@lukedavis436 thanks to 1440p I can tell you that is ASUS ZenBook UX301 featuring i7-4558U and dual 256GB SSD's in RAID configuration, just in case you find single SSD slow. You know, in laptop. After all these 5400rpm HDD which we have and love for years for speed they gave us :))
It's not newest laptop but I can guess that it run good enough for most users.
@@gorjy9610 thank you.... I was interested but Im still getting another Thinkpad as a replacement to my 0319-3tg Thinkpad Edge that got ruined a while ago :(
@@lukedavis436 I rarely have use for notebooks and even when I need one my old EliteBook 8460p is still up to the task. Thinking about buying something newer a year back but to get something similar (but obviously newer, better and faster and lighter) I need to spend much more than I'm willing to give on something uses almost never. And for less money I can get one of these plastic-fantastic toys with hinges waiting to break from a breeze. I think I'll maybe just put bigger SSD in this one, it came with 128GB but MS have mission to make windows folder about that size in near future.
Can you spell the petrol name you use please. Great video again. You can`t fix them all.
Zippo - when his says petrol he actually means the Zippo branded lighter refill fluid that cigarette smokers may use to refill their cigarette lighter with.
Any brand of lighter fluid will do since they are all petroleum based.
@@Infiniti25 Great , Thanks. It is his accent. Could not quite make it out.lol
Buy a thermal camera.. I understand you can do a job without it but if you have had one it would be easier and faster to do some jobs, buy a cheap one
You 're sure that little 3 pin things are regulators? They seem like diodes...
The one near the coin cell battery connector could be the dual diode between RTC power rail, 3V LDO rail and coin cell battery, if that's what you are referring to.
I need your help
If you’ve been offered good money to fix it then it’s possible to be fixed
not about money it's even not worth to spend it on fix it .the best choice is replacing the whole board for honesty and Peace of mind both customer and the technician
I guess the customer plugged in a usb killer
Could be a powered usb device with a 12v short to the data lines too.
Sir, I need your advice please.
my new laptop stopped to output 4K resolution to TV ("no signal")
when I switch to FHD resolution it's fine.
it's worked fine at 4K until before 2 weeks, its a new laptop (only 2 months)
I tested 10 HDMI 2.0 cables, few TV's, and reinstalled drivers and windows.
could this symptom indicate a malfunction in the HDMI port?
Video of the problem:

Im not sure if they will replace the port, or just replace the whole motherboard
