Thanks Sorin. Even the ones that don't get fixed can teach us a lot.

This is probably the most valuable video to me that you have made. It helps to remind me to move on, you can't win them all. You've got to know when to fold them. I'm in this to make money, not to win.

ABOUT PCH/CHIPSET: before, we have chipset as Northbridge (always close to cpu), which has memory controller inside, and it was "connecting" cpu, gpu, ram, and (if the integrated gpu was available on the motherboard, then it was always inside that Northbridge). And second chip - the Southbridge (far from cpu - on south), which manages Inputs/Outputs like USB, Lan, SATA, Sound, etc. Southbridge was slower and connected to Northbridge. but Now we have PCH (which is Northbridge+Southbridge merged together). but the integrated gpu is now on the cpu chip (in early version as separate silver die, but now also integrated in cpu die). btw. new PC ATX motherboards have PCH always as separate chip, placed in the middle right down. But if you take a look at i7-5600U in google graphics you will notice that this is laptop cpu - and that long silver die is a cpu and that short one is a PCH. If the laptop motherboard has that kind of cpu - then you will not find any other separated chipset on the board, because PCH is placed on the cpu. This cpu with pch on the one chip is called Hybrid. But if the laptop motherboard doesn't have that kind of Hybird, but only simple cpu as on this video, then you will find separate PCH chip on the board.

excellent analysis for sequnces of the fault , great job Sorin

Nice video Master. Thank you for the lesson

Hi my Mentor I'm a fun from Zimbabwe.....l love your good job

I have the same laptop model as this one although its a GL752v and the motherboard looks identical to the one on the video, it had the same problem as shown, it's a good abit to replace the mosfet with known working ones and then test for shorts, you probably couldn't see the short anymore since it was an open circuit, for my case it was the ceramic inductor right above the first mosfet you've removed that was causing the short, I tested back with a new inductor and the old mosfet and it worked, so sometimes these mosfets can really lead you in the wrong direction.

how can an inductor causing a short ? it doesn't make any sense . the inductor isn't connected to ground on any side it acts kinda like a fuse to smoothen the power .

I think a repair fee is ok if you take your time to disassemble the device, analize it, try to fix it, lose time and then put it back together carefully. What I don't like is some KZreadrs or shops that can't fix anything beyond simple, straight forward faults and then they charge the customer like it's unfixable when in fact they don't have the knowledge to fix it. PS5 repair, no picture, they replace the HDMI port and if it doesn't work straight away it's a no fix and the customer gets charged.

This one is actually a bargain because you get an explanation vid. You never know the skill level of a repair shop when they give such a general/poor/vague explanation of a fault, ie, dead motherboard, and when there is $1000s on the line the customer needed a thorough explanation before his mind was put to ease. Basically the 2 assessment's from the other shops was a waste of time, hence why he need this 3rd opinion.

@@screen-protector You do know Sorin only films 2 out of every 50 repairs, ie, video explanations are very rare. Sorin was saying he doesn't want to take jobs that other repair shops couldn't fix because he spends hours and they are beyond economical repair, yet he didn't make vid explanations of those. Nearly all shops don't give technical explanations, simply because the general public isn't on a level to understand it, ie, if they could understand it they could fix it themselves - lol -. When you talk to the general public you can see their eyes glaze over when you start getting technical, ie, 99.99% of the time it's a waste of time - lol -.

Thanks Sorin, 73s

Thank you for such an in-depth repair review. I was hoping for a miracle, because. Dude needs to except and buy a new mother board. Flat scares me to know how much one of these costs and how many blow and destroy themselves so easily. I would never buy a new laptop. so much cheaper to build a desktop.

Another good one! What's that screw driver u use?

The main importance about Asus, is the battery health. So if you have an Asus, you have to discharge 3x in Windows, and 4th time in Bios. You have to do it more times. Then, it can hibernate in 1%. By doing this more times, you can enhance it to high performance. Other laptops need 10 discharges in Windows , and the 11th is in bios. The lcd must be at max during discharge in bios, its coil causes the battery to become strong during bios discharge. You may need to remove the button battery of Asus, that is normal. Several cycles of this enables industrial performance, hardcore gamers will love it.

not everyone does board level repairs so shops all say that the motherboard is dead, i think that a diagnose fee is a great idea and everyone agrees to pay to be sure if it is fixable or not

im an IT repair guy and around here we have to call it fixed price cause people never want to pay it when we call it a diagnostic fee.

25 pounds is very cheap.

Thank you for this video, very informative and entertaining! I do have a question, what would cause a problem like this? a power surge? poor overclocking? faulty hardware? I am new to this electronics repair thing because I've been watching a lot of videos and I do own an ASUS laptop as of recently and I'm curious to know what could cause a problem like this so I can avoid if possible aswell or at least understand it better. Thank you. PD: I am somewhat tech savy, I have worked in IT before but nothing regarding voltages and electronics.

£25 for a fully explained diagnostic assessment vid seems like a good price to me, ie, I would be happy to pay it for an expensive item, and I would be happy to take it for the work of the vid.

Hi I am big fan

Hi Mr Sorin What is the model of your power supply You are using ?

Bravo Sorin. Seems like the fan are not the original ones. The laptop is know to provide too more heat and some customers uses fan kit from China. Asus revised in 2018 the heat system. The smal fan is not in the original computer, and the chipset was covered by the copper system in the second version. Certainly this is a heating issue, autodestroying!🔥

@Palmit_

Жыл бұрын

oh yeah! i forgot that the heat pipes have to also travel close to the components. good point!

Hey, Sorin, I got a side question, I have the same multimeter as yours, when I turn it on, I can hear as if a ventilator comes on. Is the same happening on your multimeter? What can be the source of this sound?

ASUS GL703GS I7 8750H + GTX 1070 8GB 144HRZ NEEDED TO PRESS THE POWER BUTTON 1 MINUTE CONTINUOUSLY, RELEASE AND THE LAPTOP POWER ON AFTER THAT. CHEERS!!!!

Audio is a little bit on the low side Brother Sorin. But thanks for the knowledge.

Hello, so we are back

Hello Sorin, after desoldering the mosfet, do not turn on the computer because the mosfet driver may be damaged.

Hey Sorin. Always love your videos. You don't need a thermal camera and an expensive scope to do all this. I don't have either of them, too expensive and not in a hurry like you. Do some old skool videos with petrol! Cheers.

the chipset has some connection with the gpu, maybe the power sparked over to one of those pads and it went crazy. maybe the smbus was damaged and so the ec is missing data and/or clock lines

At 11:18 you check for a short [on resistance mode] placing the red probe at one extremity of an SMD cap and the black probe at the other extremity of the SMD cap, is that what you are doing? I can’t quite see, the camera is a bit to far, for me to see. Please confirm. Thank you

foarte frumos din partea u si eu as fi procedat ca si tine

Watching you in those gloves are making my hands sweat!

Even if you have a shorted GPU removing the Core you have a good chance to have a working laptop without dedicated graphics , but the PCH is another story. Also needs expensive equipment to replace /remove them.

Its not for profit or anything. my neighbour died and i had some of his stuff. powering on makes the realtek chip pretty high temp. i removed a SMD capacitor, but no difference. i wandered if you could chat about the basics to find the problem and possibly how to repair. i dont have a laptop. it has been my dream to own one.

High Sorin if you know Northridge fix channel ,he has alot of asus and msi gaming laptop goes his way ,same problems almost, may be 10-20% are fixable.bad design ,customers pay dearly.

The GPU isn’t dead , it’s perfectly alright with the lowest resistance ever

For me any gaming laptop is a potential power bomb, they are working on the limit of they capacity, and any small problem will result in CPU or GPU short.

forgot about the battery may cause wrong reading

Looks like the pch has a missing corner exactly where it gets hot. Not able to magnifying the video enough to be sure and anyway I think you would have spotted already if where there.
