The slight rotation may be signal integrity mitigation, in order to avoid the fiber weave effect at high frequencies. This skew is to prevent the routing from aligning with the fiberglass weave pattern in the glass cloth between layers. If you have a trace sitting right over a glass bundle, and the adjacent trace is over the gaps between the bundles, the difference in dielectric constant between the glass and prepreg resin will cause the signals to have different velocities, potentially causing bus timing issues. 10-12 degrees is typical. Usually you just draw your traces in a zigzag pattern, but if there's no room, you have to also rotate the parts, or rotate the entire panel at the factory, but that wastes material.
People tend to forget that at these speed rates, digital lines have a lot of RF characteristics that have to be addressed. For example PCIe cards have to be impedance matched to the motherboard (there are standardized values)
I bought an Asus Zenbook roughly five years ago, the model number is 430UN. Out of the box it had issues with sleeping and not waking up, continues to have that problem. Two years in, the battery died and there were no original replacement parts. So now I have an ultrabook that was supposed to be high end, $1500 laptop, that cannot sleep and has no battery. Never buying Asus again even if it was the last laptop maker in the world
To be fair sleeping is a Microsoft issue, not Asus issue. For the battery you can almost always get replacement batteries if you bother to ask from proper shops. It doesn't have to be original part to work.
The green crusties destroyed everything. (Sure that is not a proper word most likely. That said picked that term up from an auto repair channel here on the old UA-cam.)
Great work Alex as always, quick and to the point. 👍👍That indeed was a weird angled GPU circuit design.. that 10-15 degrees gives some sort of isolation maybe.
??? A $2400 and it has Thermal Paste messed over components like that??? Who the heck was working on it before??? I enjoy your channel but I was disappointed that you didn't clean that Thermal paste off everything, How much extra time would it have taken, so your Work area would be clean to help with Diagnostics?
@intoxicode and that is one of the basic things what everyone should know, if there is not heatsink to transfer heat off, of course its not going to stay on because overheating 🤣🤦♂️
Hey brother! Love your videos! I only watch your videos because when you do something it gets done the correct and proper way so I know When I attempt to repair a board or replace a hdmi connector its gonna get right! You have the best repair channel on youtube!
I have a suspicion that we see these failures because of transients and EMF getting through the power supply. Either from the power grid or EMF from local sources. I always recommend a good quality line conditioner for all expensive electronics. Just my opinion.
Hey I'm buying Asus vivobook 16x and just came to your channel and it's full of Asus laps repair so should I buy an Asus lap or any other company's laptop?
Great video just like always. Like I said before I started watching your videos and for some reason they inspired me to try and learn this as a hobby, since I'm retired need something to do. I've learned quite a bit I think not just from your video's but I also watch as many different ones as possible. Today I actually replaced a charging port on a samsung galaxy tab e 8.0. for my sons work they have alot of them for the drivers. No problem. I have replaced 3 touch screens for his company I told him your company buys the parts and since I'm just learning I'lldo it for no charge. So far so good. Thanks for your videos and sharing your knowledge......
There looks like a corrosion happened to the caps and power line. Metallization on one side of the cap corroded, not burned. The damage very close to the DRMOS and may present underneath, because corrosion may spread below the mask layer. For my opinion, it is necessary to desolder the DRMOS and check the condition. After the repair, a good practice is to check that this particular power line is working like the other "neighbors". Otherwise, next DRMOS may fail under the load later. Anyway, maybe I am wrong. I like your videos - they're never boring.
Ceramic is brittle, those capacitor are multiple layers of alternate conductor +, conductor - and ceramic, with vibrations the ceramic break and the conductor + and - touch each others creating a short circuit.
Hello Alex. The capacitors as well as the resistors have been chosen by the manufacturer in such a way that they almost always operate at their maximum power. By this I mean, for example, a resistor that normally dissipates 1/2 watt is replaced by the manufacturer with a resistor that can dissipate 1/4 watt. Of course this works, but the resistance is then constantly under severe stress, which reduces the lifespan of the component. This also happens with the capacitors and even with other components. The manufacturer's aim for this is to be able to quickly bring new devices to the market. We live in a throwaway society where only the pursuit of profit counts for the manufacturers. It's a pity that we have to observe this in both Europe and the US. But that's just the reality. Greetings from Belgium. Andy
Great video, thanks for uploading! I'm a beginner when it comes to electronics, but want to start getting into it. Could you please explain to me what all the grey stuff is please? And why you didn't remove it? It looks very untidy to me, and I would want to remove it all and make it look neat. Thank you :)
Well 🎉done legend. I like watching you fixing and saving people from financial struggle. I am going to start dealing with the thing I hate most. Electronics.😂
I have similar Asus laptop. Mine is Duo Pro. Very expensive with touch screens. Had it 18 months and battery went. Asus agent here in South Africa was not intrested to replace battery for free. Had to buy and pay for new and did the install myself
I do like the design of the Zenbook Pro Duo, just a shame it's made by Asus. When their products work they are great, but their customer service is why Alex gets so many of them to repair. I had a 3 month, 26+ email battle to get a failed $8 part for a mesh router which was under warranty replaced. Only continued the battle to see how long it would take as a matter of principle. Just to see how bad they were.
"i do not have time to organize while im working" yeah as a bike mechanic i end up with a pile of tools every day lol i just throw them all on my desk and put them back at the end of the day
I bet a nice dinner that the big caps there are tantalum. It's not uncommon for tantalums to leak and blow up like that. It doesn't matter how much you pay for a system there's a certain percentage of tantalums which are expected to fail. It's just the nature of the beast. With luck it doesn't cause any further damage, maybe a power transistor at most, and you're back in business.
You would think expensive would mean reliable, but not in this day and age. As long as they can make it look premium, and charge far too much, it only needs to last past the 1 year limited warranty.
Monsieur Alex,I was wondering how much for example this fix would cost to the customer? Love your videos 📹, I'm probably getting the same amount of satisfaction as you do when it's fixed 😂
I’m starting to think that Asus sends certain models to certain regions of the US. I’ve noticed that certain regions have better luck with their machines. It’s as if they have different levels of QC, and send the worst scoring models to small towns, while sending better ones to larger towns with a bigger influence on their brand.
Did you notice anything strange with the battery whilst you were in there? I have had this laptop a while now, and somehow ended up at 50k+ cycles of the battery (via windows battery report) in just over a year of use (about 2 years ago now), literally have to keep it plugged in 24/7
Alex one of the best parts of watching these videos is to see that happy kid smile you get when you fix the problem and the device works.

The first sentence in your comment explains it all. Very well said.
@@tomclanys what did you learn bro, i didn t understand one thing ahah
Just imagine how many of these devices are simply thrown away because of some tiny capacitors failing. It's nuts.
Need automotive grade ICs next. Those bastards tolerate 20 years of harsh conditions no worries.
We don't throw them away, we just keep them in a cupboard for 12 years before binning them.
@@fraserthomson5766Too real, I’m triggered.
Can I use that comment on a future post? U will get the creative creation credit?😊
Hats off to Alex and Big Boss for saving such a beautiful and expensive device.
Alex's smile says it all - a great fix !!!
He got the two bad guys.
I was going to make a similar comment. You can tell he really enjoys his work.

Thank you! When I buy laptop i will remember ur comment. No asus
Sleeping issue can be corrected just with a registry key...you either could set it in s3 or s0 state😅
bought a asus gaming laptop about a year ago, only had problems ever since
To be fair sleeping is a Microsoft issue, not Asus issue. For the battery you can almost always get replacement batteries if you bother to ask from proper shops. It doesn't have to be original part to work.
I see corrosion on the IC near the caps and the caps themselves. A guess before the video is completed.
I noticed that too. I reckon a spillage occurred and it shorted out.

@@oldbatwit5102 Yep
Didn't you know Asus have a contract with you. They said they will keep your business supplied for years. 😂
You got the two most important things broth, tools and knowledge
It is always a pleasure to watch your videos. Great job Alex!
You are a credit to your profession, sir, oddly, enjoyable, following along your little adventure, to find the bad guy
Wow! Working successfully on a "new" PC no less! Great stuff.
Great work Alex as always, quick and to the point. 👍👍That indeed was a weird angled GPU circuit design.. that 10-15 degrees gives some sort of isolation maybe.
I don't know much about electronics, but I find your videos fascinating.
It's always good to see that smile on Alex's face after successfully saving the customer thousands of dollars.
WOW!! Two new videos, 2 days in a row/back to back! It must be Christmas already 😆
Thank you!!!

I wonder how many times he'll try powering on a laptop without a heat sink, and wonder why it won't power or stay on 🤣🤣
He needs some Big Boss skill
😂

You guys know so much! Why don't you have a You-Tube channel?
@@milfordbass To busy actually fixing devices. Dont need to make a youtube channel to know bubba.
I learn an insane amount from watching you work, thank you for the free education
This guy is the best that I have ever come across!!!
كل هالمشاكل من مكثف صغير, الله يعطيك العافية اخ علي
Now this is what you call "Better Than Factory" fix... Thank you Alex, marhabaah...
one of the caps that you replaced has green corrosion which probably was caused by a liquid damage.
caps looked like suffered from a water damage
Yeah almost like a bit of liquid got trapped under there.
Agreed. You can see corrosions nearby the caps.
Yep, see the green copper salt. The ends are corroded off the capacitors.
😮
the thermal pad probably trapped moisture there
I'm not surprised this Asus laptop died within 2years as mine as well died 2 years after the warranty expired, I was told it needs a new motherboard.

I'm not sure but it seams to me like liquid damage. I saw the greenish stuff. Good and quick Find as always. Better than Factory
Wow i dont have any words to express you alex you are just amazing tnks!
i "liked" whenever he says Yes! we fixed it! with a big smile on his face.

Why do manufacturers not have a cause, effect and repair data base for guys like yourself for them to improve their products.......

Always customers coming in with the water damage 😂.
good job easy when you see the problem. that's good looking laptop with two screens first time i have one
Their gaming top-of-line ROG mbs have been dying for no reason. Wth is wrong with asus smh
Awsome work as Always, and that Hoodie is looking Sharp! 👍
Great fix alex ? congratulation to you and wife ⭐⭐
What is all that black stuff? Looks like roofing tar.
Another fabulous fix
amazing troubleshooting steps!!! seems these days almost every electronic device fails due to capacitors lol.
You are simply amazing. Great job

Wonderful work, as always! Although I'm wondering, if this laptop is around a year old, should it not still be under warranty from the manufacturer?
the strange tilt might have something to do with signal integrity, but thats just a wild guess.
aanother great solution,,,,,, and i bet the customer will be over the moon,,,,,,,,,,,,,
I almost, always watch your videos as soon as it's out.😂😂😂

thats a pretty blown up cap, nice fix for a nice (overkill) laptop :)
this is why i only use desk tops if something goes out you won't be going through this headache

Looks like liquid damage?
Damn. I almost bought that same laptop at Microcenter a few weeks ago.
when i seen your thermal camera video it remids me Predator movie :)
I can tell you where very tired 😢. You should be resting some 😅
The voltage injection brings out the fault in the cap.
in the moment of truth, your eyes shine like those of a little boy. 👍
Nice work as always. Can someone explain what are those materials that stuck to the capacitor?
Old thermal paste
@@rawcow2496 ty for response.
Great program
Love your smile when laptops work😂❤
Excellent! :)
It would be good if those small capacitors had an internal fuse and when they break down they would simply trip and the laptop would continue working.
Can you try one of those 3D thermal cameras with IR and compare it with a regular one?!!
This is art ❤
The whole area looks pretty much like spill damage.
You just too good

Great.
Such a mess with the heatsink compound. It's not conductive is it?
I powered up an Athlon in the 90s without a heat sink and literally exploded 😮😅
I once worked on an HP laptop that has the M.2 slot slanted by about 20° and it was driving me crazy because if you install an SSD, its weird.
The company thats able of producing non failing caps will be the next billion dollar company. Come on how hard can it be.
Warranty? for the laptop surely....and then you are a service provider for warranty coverage for these companies or third party / insurance.
Thanks for the ASUS laptop review.
👍
Awesome to put it in American terms.
