How sweet of your daughter. Alex, daughters love their father the most
"I'm not pulling those numbers out on my.... Lets continue with the board." 😂😂
Yeah, I chuckled when Alex said that line, knowing full well that he omitted the a$$ word. This man is just great to listen to.
Edit: Typographical error.
👍👍👍👍👍

Looks like the chips internal VREG5 blew up. Closest capacitor to that pin might be bad. VREG3 and VREG5 are active even when EN1 and EN2 are disabled, so basically they are always on when input power is applied. Something may be shorting VREG5 to ground. VREG5 and VREG3 are 100ma Linear Regulators that output 5 V and 3.3 V, respectively. The VREG5 provides the current for the gate drivers. VREG3 functions as the main power supply for the analog circuitry of the device. A ceramic capacitor with a value of 4.7 µF or larger (X5R grade or better) is required for each of VREG5 and VREG3. It should be placed close to the VREG5 pin and the VREG3 pin respectively to stabilize the LDOs. These ceramic capacitors are the first components I would check when the VREG5 or VREG3 pin blows up like that. Closest capacitor to that pin might be bad.
Cap should be something similar to this part#: GRM188B30J475ME84
Like this post so that Alex sees it please.
Hello i have exactly the same problem, vreg5 is Vin or the main power rail so i guess it's a capacitor as you said
17:52 timestamp for all those that where wondering
How beautiful child and father relation. I am happy for u sir
That was really beautiful to watch/see. Alex is a great father. He can be very proud of his beautiful daughter. Fred
Very informative video as always and seeing the chip blow up was glorious to be honest 😂. But, the best part of the video was where your daughter got you your coffee. I am only 15 years old and I always help my parents, even if it is small things like getting groceries and seeing them smile is the most rewarding thing. When I see children help or get something thoughtful for their parents it makes me very very happy and makes me do much more for my parents.
Awesome video, keep it up!!
Todays schools teach kids to despise parents in the finest tradition of marxism.
Even though it was not an easy fix I love hearing your thought process and knowledge
You tech's that do this micro surface mount stuff are literally like surgeons. It's fascinating watching what you do. :)
You are a good father! That was very sweet.
Your beautiful daughter.. May God prolong her life and protect her.. and may God grant you long life.
Thanks for always posting quality content! 💜
Like you, your family is very generous and giving. You can say I raised my family right!
May Allah protect your daughter and the family. Truly love your work. It always amazes me how things work and how they tend to fail
What a down to earth guy you are with a wonderful daughter making papa a cup of something to drink. Great video, thanks very much
Good health to the family from Romania! I follow you and learn many things from you!
Many pads under the destroyed chip are connected together by solder bridges, suggest to clear that area before any further measurement。
I thought that the new solder blob on the ground pad when the chip was replaced was on the large side at 10.56 and did wonder if when pressed down it had created a short.
What looks like bridges could simply be flux between the pins and the glare from the lights
That was glare
@@NorthridgeFix VIN and vreg (if not mistaken) are fused together tho, you even lifted them.
The pads were like Hiroshima and Nagasaki melted together.
I don't know this chip in particular, but a quick Google search shows VREG5 normally has about 5V generated by the LDO.
If VIN (which was 19 volt I believe?) was connected to the 5V rail, lot of components on that 5V could have died as well.
But I hope I am off by a mile and you get this laptop running again, even tho it would be more complicated now than it already was, sometimes you have to do 1 step back to do 2 steps forward :)
Congratulations my friend to you and your family!!! I love watching your videos!!!
Incredible job troubleshooting Alex! Hopefully you can get this one working again! Rooting for you on this one!
Adorable daughter. So sweet 😊
bless your children man. you ruin your eyes and your back all day over goddamn machines for the sake of their well being. keep doing what you do for the higher purpose.
Your daughter is so cute, and she obviously cares about you. Count your blessings.
a good profession, it's a pity that there was no Internet before
You daughter is growing tall. I have been with this channel for a very long time. always respect and I learnt a lot from you. 💯NorthridgeFIx.
I Felt your pain when that chip blew up 😲
@NorthridgeFix that chip was heating up because a thing was shorting on the 5v / 3.3v rail. The enable line voltage will only be present if the output voltage of the chip is at 5v or 3.3v. Its a safety system for most laptops. I had the same problem with my old laptop. Something was shorting on the 5v rail which affected the 3.3v rail as well. Once i removed the faulty chip the 5v / 3.3v chip did not heat up and 5v and 3.3v was present. On gaming laptops these things are common because people use it for extreme performance.
I have this exact issue. Do you remember which chip you had to remove?
Thanks
You are truly a nice guy. I wish I had 1/3 of your knowledge. Nice to see your family in your videos. So cute! You deserve all the success that you receive! Love your video's and you sharing your knowledge.
you actually fixed the problem in 2:25 The broken capacitor escaped his attention.
Looks like it's just a dust particle or something.
I think its broken
Mashallah your daughter is blessed to have a good dad like you.
All the work , your enjoyment/aches is worth it's cause
Excellent video, as always! 👍
Nice to see Your daughter to bring morning drink to father! My daughter is helping me every time too.. 😇
At first glance, looked like You short out two voltage lines with multimeter probe, but rewatching part of video, shows, that You barely touched one leg.. Mysterious situation, indeed. You touched it with probe, and chip blow up.. 😂 Never seen this before under microscope!
Thanks for sharing experience! 😉
I loved seeing you and your daughter very sweet. Love your work keep it up.
After the chip blew I’m waiting for the words “and now we have another doner board, that’s great.” 😂.
Loved seeing you with your daughter.
a lovely gesture from a lovely kid
A Good Repairman, A Good Father.
Love to see the smile on your daughter, and your face. You can see the love. I lost my daughter right before her 16th birthday just under a year ago. It has left a hole that cannot be filled. Spend as much time as you can with her and hug her tight. Love your videos keep them coming
sorry about your loss brother....i have 5 years the only daughter.
How are you doing Eddie?
@@MadMax-yq9ix I'm hanging in there. It's something I wouldn't wish on anyone. I know she watches over me, and will be there waiting when it's my time to go. Can't fear it now since I have most of my family ready to welcome me home when it's my time. Hopefully that is a long time from now as I still have many things to do, and people to help. I appreciate you asking. I hope all is well with you
Sorry about your loss Eddie
Your daughter... That kiss on the cheek was priceless.
Is there a part 3?
No smoke? no sparks? just a hole on the chip? Great video though, keep up the good work!
Whats up ! bro, are you ok? Here in Brazil everything is fine, thank God!
Here on my bench I always start like this also in this sequence: DCjack 19volts, then I test all the mosfets on the board, then the current sensor, if everything is ok, then I will check the coils, because in it we must find the primary voltages of the 3.3v and 5v board , generated by the PWM or by the Pwm's of the board in some cases we have more than one. if the voltages do not really exist we have a short. And then I test the primary PWM of the board and see if it has 19v and 3.3v or 5v output to the coils. if nothing works, I go to the capacitors. But if I find the short, I always inject a voltage of 1v with at least 1.5 ampere. So after all that, we have a high probability of finding the problem with the board. In this case te PWM was bad!
Shes so thoughtful bringing you more coffee xD
Compost happens Alex.
I love the bring your Dad a coffee/tea for the spilled one.
I can`t believe you made the same mistake like me by shortig the 19v with 5v :)) So i had the same problem and in my case the IT8225VG-128 was causing it .
I would never risk to leave the board connected for so long knowing how hot it gets
Skip to 17:55 and enjoy 👍😁
Küçük bir dikkatsizlik çipi havaya uçurdu. Sağlık olsun...
1:50 The 3 capacitors in the upper left part of the picture appear to be broken in the middle.
how the story of this laptop ended, is there a continuation? both chips were dead?
Where is the update?? Are you fix that or not??
Dude thanks for publishing this video, this is the real day of a technical assistance. Many only post the successes, but you post the reality, so we see that it's not just on our benches that problems happen, and that all technicians go through it. With that, we must move forward, and not let these problems, and non-repairs affect our psychological and emotional. For nothing like one day after another, and it is God who empowers us and gives us thanks every day to move forward in the strength of the Lord Jesus Christ and the Holy Spirit who dwells in us. Congratulations for the excellent work. Always | Better than the factory one |. Forward always! God dwells in us!
Very good!!!
PCH possible. Look the pch one side discolouring. Yes am sure pch
You might be right. If it’s not the cap that’s shorted then it’s something nearby that’s getting hot
Gad bless your daughter alex🙏
17:55 you are welcome
Was there any continuation?
Measure the vreg3 and vreg5 resistance, which ever has the low resistance... inject voltage and whatever heats up is dead.
hi alex great video as always . obviously your daughter has her mothers looks haha shes a cutie pie ....
Wondered if the "donor" board could have been used to replace the bad one?
With some upgrading and repair of it, quite possibly there could have been a fix to this one.
Looks like Asus is showing just how badly their stuff is and maybe causing Asus sales to plummet due to seeing all the problems that come up here.
As I had said before, I have a Dell from 2017 XPS 15 9560 that stays on almost 24/7 since I bought it. It has traveled with me all over the world and only thing replaced was the power cord.
I open it occasionally and clean it keeping the fans clean and the heat sink clear of fuzz and debris.
Never a problem.
The touch screen works just as well as the first day.
I'll probably buy a new one in the next year so that I have an updated current model.
Asus keeps you in business and profitable. Of course I know that you do many other repairs of all kinds of electronics. After watching some of these HVAC repair guys shows, I can say that there is a good business in board repair from what I have seen in their line of work.
Some of those HVAC boards are complicated looking but I'm sure that it all gets down to component failure.
I even saw a car mechanic find a key fob module failure due to a water leak getting the board wet. I suppose the question is........what is more expensive, buying or repairing the old board.
With PC's being so expensive, I can see how a cheap repair is much more economical.
And with your vast experience in electronic diagnosis, you're job and business is safe from ever becoming redundant.
I suppose that the military will soon be jobbing out their B1 and B2 bomber avionic components to you as well as F-35 boards.
make my hair stand especially when checking the chips thru microscope..God bless your family sir
17:58 instant replay of title chip blowing up
mmm crispy ... I would need a drink after vaporizing this chip ...
4:25 I understood "we have tumor" :))
Jack of all trade, Master of NONE
Has a Part 3 come out on this yet? I'm hyper intrigued!
He can fix it by repairing the donor baord hopefully, with the new parts from this new donor board. That burned a hole in the PCB to ground. Sucks but these thing happen.
You have a good kid, she obviously thinks highly of you.
Good video brother and i learned lot of knowledge on your videos❤️
16:06 maybe im crazy but i see a blob of solider touch that cap . When it over flown out the mosfet
8:40 adult sippy cup 😁
Yup that one looked like it let all the magic smoke out. Anyway it is the coupling caps that go that cause these to go chernobyl. Those SMD tantalum caps are notorious for that. If possible replace with a MMLC or piggyback a 0.1uF mmlc over it.
Very cute daughter. Maybe she will repair Asus laptop one day.
Some channels have the multimeter on the screen.. just so we can see what you see.
Mash Allah beautiful doughter May Allah Protect her INHS ALLAH
i just realized how hard to repair this thing. even experts are saying "what is this/ i don't know what this is."
The ic should not get heat just for not having the enable signal. I think that most likely its getting Hot because something ahead
Maşallah for little cute child .
super io is the problem i got this fault before
judging by the look of some of the mosfets they have already had some work done on the board and changed a few
The system 3V&5V IC is so hot because LDO3 or LDO5 short to ground, you could remove this power IC, and use thermal camera to check which IC burned. In my experience, EC is always short to ground.
I measured all pins of the chip including LDO3 and LDO5 Nothing is shorting to ground.
@@NorthridgeFix You could provide 5V to LDO5 or 3V to LDO3 manually to check again if possible.
@@МаньякПсих-ь5ж true
It is not shorted to ground. Maybe the 19v coming true a component (fet?) and pumping up the 5. Chip is trying to get it stepped down but it is simply to much.
Laptops will always overheat because of its compact design no air flow/breathing space unlike a desktop has plenty of space for many upgrades for improvements&savings...
17:57 wow! charge them extra for the fireworks show... 🎆
4:44 Best answer ever 😂😂😂
Where do you get your donor boards from, i work for a good sized refurbished laptop store as the lead repair tech, i have a library of about 1000 donor laptops, but i never seem to have the right boards for the kind of board repair i have to do with the walk in repairs
Oh father's love and sweet baby girl ❤️❤️❤️❤️
17:54 boom!
One thing I have learned watching your channel: "Stay away from Asus laptops." Or is it one specific model? 🤔
Chip said fairwell
You have a beautiful daughter MashAllah
13:25 i thinks there's a hole on those middle caps.
nah
Please make part 2 🙏🏻
All your hard work paid 9f by your daughter kiss ❤️
good people
Was there a Part 2 of this?
would it not be awesome if you could just get your readings on you microscope screen ...
The explosion!! 17:54
Repair pad using flat FFC / FPC fkexible cable, it's more tidy
I don't find the 2nd part. Please help :)
ربنا يحفظهالك ويخليكم لبعض
Stand by entegresi sökülüyken voltaj verilmez diye biliyorum.
Has there been an update to this repair?
MasaAllah she is very cute.
