I got shocked and supprised and felt like a real goal scored by sorin 31:18 when I heard "we have the charging light, that's insane.." like the surgery was successful.
You read my mind when you pulled that chip again to check it. You videos are among my favorite because you keep it real Sorin. People need to see reality, and they get that with your channel. Sometimes things don't go as expected. We are imperfect, and we can make mistakes. But we can sometimes recovery from our mistakes and still get satisfaction for job well done!
Fun fact, I was watching this video from a UX363 that came in for repair for the exactly same fault. Fortunately, it was only a charger issue and anyway it is under warranty, but it was nice seeing your video.
Well done Sorin, good to see you still get excited after a successfull repair! Keep on doing what you do, we learn a lot from you. Greetings from South-Africa.
next time you should waste an extra one minute to wick the pads on the board, and replace with low melt solder, you will even be able to lower the temperature to solder back!!
Sorin, if the Asus laptop motherboard is similar to their desktop motherboards, after changing any components, the bios does an updating and training routine that takes a couple of minutes to complete. Thus the long black screen and update time. Also, the LED keyboard is programmable for visual effects. WB
Another successful repair, I'm glad to see that you decided to order on Mouser. I hope the customer is also satisfied and will pay for the repair costs
Ta karteczka co wypadła z torby jest bardzo ważna. To znaczy że produkt był przechowywany w odpowiednich warunkach. I teraz trzeba zobaczyć na ten tester w jakim stanie dotarł. Czyli ile wilgoci wchłonął podczas transportu. Wilgoć i wysoką temperatura nie są dobrym połączeniem. Wilgoć chce szybko wyparować i może rozwarstwiać układ.
If you buy a chip and they are a good seller they clean it. And you have to solder the chip because there is a layer of oxidation from the cleaner. And it wil not bond with the solder. Iam happy you found it and get it working.
"Don't tell anyone, I'll never admit it" As he leaves it in the video. 🤭 Sorin, you did good, at least you had the insight to check your work before condemning it. We ALL make mistakes! 😉
I believe that chip needed to get programed from bios, that's why it took so long to start the first time, and it finished the job after starting, through update
That QFN failed soldering is like how all my QFN soldering look like on the first 3 attempts, usually after I burned my hands twice getting it to position 😁
I have a Dell XPS 13 with the same chip. And the same problem. I've ordered a replacement from mouser and will try to replace it. I'm new to hot air soldering so I'll definitely watch some tutorials first.
Sorin, this is not the first time I experienced the pins on the chip needed to be cleaned and tinned. Maybe, caused by the solder used by the manufacturer to tin the pads on the IC.
Great video, like a kid on Christmas morning 🤣 Your persistence paid off. And you showed how important it is to correctly solder a component like this. 🤭 You did that on purpose didn't you? 🤫😜
Sorin, you need to clean the pads of the old solder first, prep pads with new solder before you solder the new chip in place. I have tried soldering these chips without doing this and they most times do not solder right and I only end up burning the chip trying to get it right. I never solder a QFN chip now without cleaning the pads first.
Your works has been a great motivation to me Just don’t know how to get those equipments your using Cus we really need something like that in Nigeria. Nice work sire
Awesome job Sorin, but you scared the crap out of me when you yelled 😅😅😅 normally i have to increase volume pretty high to hear you, and when you yelled it was then very loud and unexpected 😂😂
I’m amazed by this soldering method. How much heat can those chips withstand? Years ago, when I was soldering chips with holes in the board, and they would warn us about using too much heat. Are newer chips more heat resistant?
Great video as always 🤓 Could it be that new chips come with a protective film layer on the contacts that need to be burned or cleaned off, may explain that which we did not see 🤣
It is not that. It's due to Sorin's bad habit of reusing existing unleaded solder. The proper way to do it is adding flux to the pads, tin the pads with leaded solder and then reflow the chip in place. If you just desolder the chip and try to use the remaining solder to do the job, things like that do happen alot.
It almost looks like it was the chip doing the update. You soldered the chip and it was not initiated. When the laptop started the chip called for an update and updated itself with new firmware?
1. So it seems it's not like those pesky undocummented realtek chips with "it's NDA" kind of support. TI says in the DS: "Initial device configuration is configured through a configuration bundle loaded onto the device DURING BOOT. The bundle may be loaded through I2C or SPI." However there is some kind of firmware GUI config tool. 2. Aren't you afraid you'll melt some plastics under the board?
I believe you should clean the old solder when you take off the bad chip and reflow with new solder and then put new chip, I dont trust the solder on new chips Sorin just my opinion.
Good afternoon. I'm based in the UK and have a similar issue with my UX363 notebook? Sometimes it works for hours on end with no issues, other times it will require a power button discharge before it turns on. Now as of yesterday (14.08.24) after 6 months of on and off use, it fails to power up at all, no power led. What do you think my options are? 🤔 Many thanks in advance!
I told you to buy chips from Mouser or an authorized vendor. Especially if it's a complicated chip maybe MOSFET or capacitors have tolerance of fault of manufacture. Good luck
30:25 no Sorin, this time is not good. Right side, 4th pin from the top and one above right down corner. You added new solder to the middle of the big ground pads under the chip, which was good idea, BUT if so, then during the heating, you have to press down the chip UNTIL you see the big balls of solder coming out from the edges. You pushed it down very well BUT I didn't see these balls coming out, so it means that the solder under the chip were not proper melted (solder outside the chip were melted - yes, but not under the chip on the huge ground pad) You heated it not enough time. So you soldered it but it didn't sit down to flat completely - so some pins can be unsoldered.
@Mr Guru yes. I told him many times in the past when he solder high power mosfets. Maybe it is not because of me, but now he is doing it very well - always he is pusihing it down. Here on this video he also pushed that IC down- so he understand how it needs to be done, but this time it was not enough heat.
I have the same laptop and issue, stopped receiving power through the usbc ports. I took It to a repair shop and they told me it would need a whole new motherboard replacement. Was it just that 1 chip on the board the he replaced that was the issue?
Yup that chip need firmware to run. I have read the documention on that chip. Texsas Instrumen do provide the tools to program it. The chip also support external bios chip, to store the firmware. The chip can be reprogram with any SPI/I2C programmer. The tools natively support FTDI, Aardvark and TIVA programmer.
I have a similar laptop but in my case, the laptop turns on, but does not charge. The second USB-C port does not work either, and the laptop just turns on with the first USB-C port. Do I have to replace the same chip?
Battery was too low, that is why it was negotiating 14V only. Once it picked up, it had increase it. However, can't believe how "ballsy" you are to desolder/solder the chip without removing the board... and with the screen closed
@@orange11squares In this case the screen is quite safe because it's touch and the digitizer can take heat, but connectors or palmrest or keyboard are easily damageable indeed.
Salut! Daca inca mai ai laptopul am nevoie de o valoare a unei rezistente. Nu gasesc schema nicaieri. Am intrebat pe discord dar nu am primit nimic. Mulțumesc!

The moment of joy when you fix the device is a unique feeling that just a repair man can undrestand.

wow sorin ive never seen you so happy at a repair im so pleased for you and the customer ..
Your passion is a example for many
Well done Sorin, good to see you still get excited after a successfull repair! Keep on doing what you do, we learn a lot from you. Greetings from South-Africa.

Sorin…apply fresh Solder…I can’t believe! 👌
Don't worry Sorin my eyes were shut. But be sure to clean the pads next time and add new solder before reflowing the chip.Btw. congrats, nice repair.
Another successful repair, I'm glad to see that you decided to order on Mouser. I hope the customer is also satisfied and will pay for the repair costs
Sorin "I can't believe" 😂😂😂
🤣🤣🤣
I can't.

You never cease to amaze me and make me laugh.

It's all right, i didn't see nothing, my eyes close while watching this video. Good job.

I' m also heating the pads on the motherboard at 480° for a while before placing flux and new chip .. that i will reflow at 370°...

is that true, this shooting of compilation video was paused someday because you must order and wait new chip from Mouser shop?
Great job but I have a question why the ic is not coming with a solder on it?!

Awesome troubleshooting algorithm!
The last one with the DJ chip problem was doing windows update too.

There is a protocol
Rule no1
Clean the area and put new solder

Those chip any 3 series DJ,DH, and CE
I saw nothing 🙂but a great video once more.
Battery was too low, that is why it was negotiating 14V only. Once it picked up, it had increase it.
However, can't believe how "ballsy" you are to desolder/solder the chip without removing the board... and with the screen closed
what he did is not very wise, one can easily damage the case or some connector or the screen.

Mega Sorin - i like to see your Videos - And again a Great Job - a Great Video - Super - Thx
I start to check the power from the usb-c
And then I find the main and the 3.3 present
Good job mate 👍
Congratulations! You are good!)
I'm happy too :) thanks
hello sorin
if I remember the other one died on a Windows update exactly like this one
Very good. Thank you :) !
I CAN'T BELEIVE = The magic words.

Nice one
27:44 what happened, I had to go to the toilet 😎
Bad service from Asus - I18 month warrantee for a laptop isnt long enough, the EU specifies a minimum of 2 years..
Zawsze należy na nowy chip nałożyć cynę. Zawsze tam jest jakaś oksydacja i nóżki nowego nie pokryją się cyna z płyty. Będą przerwy na nich.
And the china chip was soldering properly? Maybe there was same problem like this time???
the laptop has been turned off or losing battery power during the system updates probably
Wow that was my first reaction when I was 100 successful on that fuse I change. Hahaha
27:42 never happened with the rosin flux never
