25:47 you almost deemed it a no fix. It's so scary, if you didn't have eyes on the amp screen, you wouldn't have noticed it dropping to zero. Such a crucial detail.
The dust is from an atomizer. You put powered flux in it and spray on the board it act's the same as putting alcohol on the board. You can see which bit turns to liquid, i.e., the hot spot, another great video 👍
Man, when a laptop has a dusty motherboard, before i check or assume anything, i can assume a short can be anywhere basically because dust can very likely contain conductive material, that's why i always first clean it and then check for actual shorts, you know, just in case.
What was the purpose of removing the CMOS battery and shorting the positive and negative? I know something to do with the bios as you said. my main question is what problem would that fix?
Depends on cpu generation. If this laptop has an i3-5005 2ghz without turbo it's around 0.6 to 0.75V I5-8365U default: 0.65 on idle to around 1.275. I undervolt lot's of them with -150mv on core and -75 on cache, this gives a major improvement on them with i7-1165G7 performance.
Sir i had one doubt the technique you are using to find the short and applying the voltage with the power supply could we use it in any like desktop mother boards circuits etc..if possible please explain
You need to watch his videos and understand his method I don't think he or anyone else can explain it to you with a comment. It takes time but that's how you go. Suppose someone tells you it's fine still you need to know when and how and see it yourself to believe it !
you can use this technique almost anywhere ,to find the faulty(shorted) chip or component. Low voltage - 0.9-1 v and a bit of current will tell you where short is.
good eveening, please i have an hp 250 g6 laptop that can charge,3.3v is presence on the power button but can't turn. please how can i solve this problem?
Hello mister, i have an issue with my laptop. İ have a hp 250 g5 laptop, 3 weeks ago while i was studying for my exam, it suddenly shut down with a click sound and it wont turned on. When i plugged in the charger the charhing led was blinking. Normally this wouldn't happen when it was charging, the light would come on solidly. Then, i press to power button, it opened for 1 second and went off immediately with the same click sound. İt was just like a fuse blown sound. When i press to the power button again nothing happened for this time. What should i do? Also this happened 1 week after my laptop came from repair and i dont know how should i tell this to my family im a university student and last repair was on the motherboard and it costed too expensive 😭😭😭😭😭😭😭😭😭
you want repair by yourself::;;!!fist check led of power supply if has does turn off when put in pc could be a short : check battery remove and try without ::try to charg battery manualy with two wire plus minus and so on in diagonstic
I believe it is not very common for the LDO 3,3 power supply to fail. there are capacitors around this chip, I would check them all also, before replacing the actual chip. Something caused this chip to fail.

Guys i just want remember you the top 1 video of all this channel. Where Sorin Reach the Max Level and unlock Frankenstein mod *Sorin Skill / Max *Sorin Knowledge / Max *Sorin Doogie / Max *Sorin pause smoking/ exploded the record ua-cam.com/video/lwmUa99KUys/v-deo.html
I can't help but remember some kind of meme where an women was selling her HP laptop but she read it upside down and said it was DY. HAHAHA I can't blame her and you can't also, everytime you see a HP laptop over the table closed when you face it before opening.
Who waiting New video every day from Sorin? 🎉
We all do , i feel like i found a gold mine, i hope that he never stops uploading videos
Daily dodginess 😂
Me are
I don't wait, but I like it when browse YT while eating and I find his new upload.
I am Waiting every day a new video from sorin last five years 🇧🇩🇧🇩🇧🇩
You the only tech I know that enjoys fixing and helping customers. Even after all these years you have the same excitement as if is your first repair.
The videos from Sorin are better than crime series on Netflix :-) Thanks
😄😄😄
I throw away my TV 🚮and only watch Sorin on PC💻⌨😃
My favorite phrase "We have picture! I can't believe."
Thermal Camera is the best friend of every repairman.
💯 imagine, how much time it saves !
25:47 you almost deemed it a no fix. It's so scary, if you didn't have eyes on the amp screen, you wouldn't have noticed it dropping to zero. Such a crucial detail.
33:47 We have the picture. I am very happy to hear you🤩
Sorin is the best teacher
The dust is from an atomizer. You put powered flux in it and spray on the board it act's the same as putting alcohol on the board. You can see which bit turns to liquid, i.e., the hot spot, another great video 👍
Never heard of a rosin atomizer before so it's true that you learn something new every day!!
Actually the dust would have melted from sorin using heat and it wouldn't be so sparkly. It's something else.
Thank You Sorin for sharing all your knowledge with us always wait for your new videos Hi from Chicago
We have picture!!! I can't believe it!!! It's my favorite time
sorin, little by little - trying t get minimum tools to get going. thanks for the great videos.
Man, when a laptop has a dusty motherboard, before i check or assume anything, i can assume a short can be anywhere basically because dust can very likely contain conductive material, that's why i always first clean it and then check for actual shorts, you know, just in case.
you made mistake not calling your rosin ( Sorin Rosin) its so good name and its going together perfectly!
It’s amazing to see how you do❤❤❤
paypal in the description work great ! i send you $ for every video when you say "We Have Picture"
Great job Sorin... as alaway thanl for the troubleshooting experience bye Francesco Timpano fron Florence Italy
Sorin your videos is just like coffee it is addicting.😊
Thank you and goodjob always
Disco motherboard 🤩✨✨✨
Thank you Sorin 😘😘
Nice video 🙏🙏🙏. We are improving knowledge with you. Thanks very much.
Good job
hi sorin sir i have learn lots of things from you love you sir
Thanks🌹 for response
thank you Mr Sorin
great video! I think this is the first time we a see cpu power driver chip faulty if I'm not wrong.
king of electronic
So informative video ❤
Nice one master Power supply cpu driver is a rare fault.
Using alcohol as a tool. Amazing! I'll keep that in mind next time.
Wt beautifull case ❤❤❤ thermal camera play tha main role
🎉 Nice work 🎉🎉. But how do you know the first chip that in older mother bored same with the burned chip?
What was the purpose of removing the CMOS battery and shorting the positive and negative? I know something to do with the bios as you said. my main question is what problem would that fix?
Good job mate 👍
your my master lot things to learn
35:23 Was this video made on September 4th
when Sorin said cpu is cold and the vcore only 0.5, I knew something was wrong there
normal vcore for i7 should be around 1-1.2V
Depends on cpu generation.
If this laptop has an i3-5005 2ghz without turbo it's around 0.6 to 0.75V
I5-8365U default: 0.65 on idle to around 1.275. I undervolt lot's of them with -150mv on core and -75 on cache, this gives a major improvement on them with i7-1165G7 performance.
@@harrydijkstra9936 in this case it's i7
what was the temperature when you do desolder and solder that chip @30:36
Whats the trick you do by shorting the laptop charger connector in order to adjust the current?
Another great lessons
I will check soon but i think i have seen this on lenovo b590 motherboard and that 3.3v,5v ldo + 5v main chip might be tps51123
U are the best.❤
4:55 looks like there was an insulating tape over that area of the board to prevent what happened here. 😅
Smooth to the groove 🕺🏼
Very good sir
How to I join as students to you
sometimes the older ones are the best ones!

Check out "Learn Electronics Repair" where he presents fault-finding techniques to fix anything.
Nice one
I have a 250 g9 that's making a grinding sound and I have no idea what's causing it
You are awesome

16:24 I was screaming "Check if short is gone before you solder the new chip!" 😅
Can a laptop work without the PU2 chip?
daca schimbi cip-ul nu se va strica si el ?
😊😊😊well done!😊😊😊
So schematics are also very important
👏👏👏👏👏👏👏👏👏👏👏 saludos desde Buenos Aires Argentina
Somos dos, abrazo grande!
You said this was a cheap job, but how cheap if the laptop is old?
Sorin: my knowledge is very OK.
Internet:
I believe it is not very common for the LDO 3,3 power supply to fail. there are capacitors around this chip, I would check them all also, before replacing the actual chip. Something caused this chip to fail.
It's not so uncommon, even Sorin have many videos with them failed.
How do I contact you Sir. I tried the links in the description but they either dont work or take me to a dead page.
Discord
@@MattyEngland yeah I had to log into a VPN to gain access to the site and discord. Seems they dont accept business from the US. Hopefully they can make an exception if I pay upfront and send a little extra for the help
@@kryptodoozy I think sorin has had trouble with international jobs before, that's why he doesn't usually do them.
@@MattyEngland well I'm willing to pay for his services and for the shipping cost back to the US in advance.
Hey i bought an Asus Vivobook laptop it got onboard ram of 8gb(part name micron 4ATF51264HZ-3G2) but i want to make it 16gb is there any way plss help
❤️❤️❤️
The glitter provoking a glitch In the matrix ; = )
WEEEE HAVE PICTUREEEEEEEEEEE, i cant believe xDDDD thats my fav music
When i plug charger the touchpad freezing
Use original power adapter sir
Had that with an old adapter that had worn out capacitors producing noise on the laptops power rail causing the trackpad to react weird...
Just a suggestion, but if you made your cursor black, we could follow it better on your computer.
that dust could be metal dust
the what chip is dead?
We have picture. This is crazy. I can`t believe.
Glitter Sorin
we have picture i can't believe we help the customer
i think many do

I only come here for 'picture'
Wow in standby it consumes less than 10mA.
Glitter board
forums are not so popular anyway in those time when ppl want instantly response...
Hello🤝👍👍👍👍👍👍👏👏👏👏👏👏👋👋👋👋👋👋👋
I can't help but remember some kind of meme where an women was selling her HP laptop but she read it upside down and said it was DY.
HAHAHA
I can't blame her and you can't also, everytime you see a HP laptop over the table closed when you face it before opening.
What percentage of "Computer Repair Shops" cannot repair a motherboard ? If I couldn't do it I would feel like a fake tech.
I'd guess more than 95%.
Dua lipa’s laptop
cmon its not old its still amazing fast laptop....
Bravo!!!!
whaa, no dead capacitor 😄
😋 we have picturre
i always have those kind of reparations ffs xDDDDD
Why i hate the ios system?

First
If you cut it a little shorter, the videos will definitely be better received
