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 KZbin channel, im still trying to find good quality cameras

[@northpoint1039]

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.

[@regresoderambo]

yeah like no one, most repair people show is about a shorted capacitor or 19v mosfet power rail and does it or charging conector broken

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.

You're right, because the MOSFETs gates will floating without the chip. I hope he sees your comment!

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.

[@piernov]

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.

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

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?

[@michaelparanormal]

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!

[@MrRvdbeek]

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

[@Todestelzer]

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.

[@titaniumdiveknife]

Respect.

[@19mati67]

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

[@gvitservices]

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.

[@princetechARD]

hello sir, what kind of overhead camera are you using now?

[@Domienproductions]

Do you charge any diagnosis time to the customer when you cannot fix it?

[@electronicsrepairschool]

No!

[@markusreichel3896]

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.

[@piernov]

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.

[@جساس-ه6ح]

this laptop needs more amps, give it 100 amps nothing to lose

[@rexeffect7122]

This probably would have been a fixable job, if the customer didn’t try to fix it.

[@piernov]

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.

[@Todestelzer]

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.

[@EDVDompteur]

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?

[@namzer0]

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.
