My mistake, its not the transistor on short, its was the transinstor pin to the ground! that transistor its on serial mode with 19v ,so even if its on short, the laptop still should work fine
so if i understanding correctly ( transistor is a resistor who can change the value) the pin of transistor should not be ground and the video why saw it was going to ground, thats why looking for short to ground component?
You are a sweet person who's so kind to tech others and pass on the knowledge and skills you've aquired through years of hardwork. I thank you from the bottom of my heart for your generosity and wish you and yours the best ever. Good luck and cheers. 😍😊👍
hes an angry person by nature who is nice on camera.. guarantee you when he gets dementia,,, he wont be a nice person with dementia ..but most people with it are mean only some stay nice..
Im 21 years old. I'm really dumb and i don't get some of your common sense but I believe you are a great teacher. I gain knowledge from watching your videos. Thank you! And I love you! It helps me lot!
Good sir, I cant thank you enough for your teachings here in videos. I just applied the methods you did in this video to diagnose and repair a samsung tablet. I've been a technician for quite some time but most I do is parts replacement on laptops/smartphones and never really dived into motherboard level repair. I recently got into laptop motherboard repairs and revived quite a few old laptops in my shop now thank to your teachings 👍👍👍
I've been trying to learn how to repair laptops for a few months now and can't find anything that works anywhere. to date...in these few videos on this channel I have learned more than in the last month or two. Thank you...
Finally! After so much research I found your channel. I have the Lenovo laptop with extremely hot chip and at least I have a clue what to do next. Thank you for this great channel!
i have not even watched the video but i just press the like button coz i know that you are about to show your level of genius at it peak ......great job boss
Oh my god. the way you fix and how you teach the same way is freakin perfect.. I want to learn a lot when it comes to technical things hope you keep teaching me or us :)) keep up the good work sir more power for you
out of all of TH-cam videos you are the best I have seen, i have downloaded all your videos , thank you very much for your help, i wish you all the best my teacher
I was here thank you. Got the same old laptop I use for the shop. Works fine bit sometimes overheats. So I opened mine while watching you fix yours. Awesome 👌
03:57 "Even if I'll not fix this, I'll still upload this video.💪 Obviously, no one is perfect. You can't fix all... " I like that attitude..👍 Sometimes we should accept our failure. There is no problem with that.🤷♂️ That's why I like you, no.. no.. no..🙄 Thats why I love you.. 18:15 Thank you master for educating us about the 'SAVAGE WAY'😎 (Brute Force) to find the short. God bless you...
Thank you for a nice video. Very thoughtful camerawork with screen in screen mode, the microscope, the lights. How do you know you are not going to burn any motherboard components by sending 4A into the board?
This is the very best diagnostics video I have ever seen. I know the video is older but, I have an IBM T60 that is "dead" so I was looking for a video just like this one. Thank you. I am now subbed.
It's worth the watch. Sometime's, you just need is skill and patience to solve the problem. Thank you for this video. Greetings from Philippines! I have a HP unit now. I think it does have the same problem. Unit still turned on, after a few seconds. It shuts down. Thank you for the idea, now I know where to look
@@martijn4740 ummm.. I saw sparks at one point. you pour lighter fluid on the motherboard and sparks can't ignite it? That is exactly how a cigarette lighter works. Wick draws up lighter fluid, flick the wheel to generate a spark and the lighter fluid in the wick ignites.
Sorin, this is just a hobby for me, but i have managed to repair some small things like lcd panels. Thanks!!! If we ever meet beers are on me!!! Cheers
I've always known, that on day when Russians will start to speak English, the world will get a lot smarter. You guys have very good skills on teaching people how to do things. Nice video! I like your style!
He’s not Russian lol and even if he was not all Russians are good at teaching things 😂just like not all americans are good at anything because everyone is different. Has nothing to do with culture or race it’s just weird that you even brought that up
Well, I guess I will have to sit down for a few days. Have a lot to catch up. If I get to fix a dell latitude that has the same issues as your hp, I´ll let you know. Thanks for taking the time to make the video.
I think you would benefit from owning a thermal camera? You could then easily see what is getting hot on the motherboard (would also stop you burning your fingers ;-)
Yes Anders, you are right, every rail is created from the 19V main power rail with 2 mosfets, an inductor and a capacitor. Sometimes you'll see more than one power rail output connected to each other, they are outputting the same voltage but they are there for higher current draws. Best regards FixDaily - Electronics fix tips channel
Your welcome. I've tried the ISO evaporation method on a board i worked on last week. No luck. It draws 7.2 amps from the 3.3 volt power supply (external substitution) and not a single damn things gets hot, or even warm, on the boards. The power leads get hot - lol. I must have an inner layer board short or short under one of the ball grid chips (really hefty tin whisker maybe). Anyway, you video setup for your power supply and DVM readout works so well, along with the video source of you and your microscope. I was very impressed.
I had tantalum caps in short before and they don't get hot, try to isolate the 3.3V power supply from the rest and try to see what is happening there with your multimeter in continuity mode. But remove the tantalum of your 3v3 power rail and see how it goes, it is easier to solder back again. And never put 7.2Amps because your board traces and vias might not be able to handle so much current and you will end up destroying your board. Usually 2.5 Amps would be enough to test things up and for a short period of time. Best regards FixDaily - Electronics fix tips channel
Fantastic video, sir. I learnt a few new things from this. But I would like to know what that liquid you poured onto the heated capacitor was. Is it alcohol?
20:00 😂. You are the most fascinating person on TH-cam. I’m following along trying to repair my HP laptop that has a burning mosfet and I burned my finger also, know the feeling.
One suggestion to make your videos better. Fast forward through all the easy and timely unscrewing! Also explaining a little more about the tools you are using if this video is intended for noobs. What kind of liquid are you pouring over the motherboard?
dude your awesome I have taken my laptop to two techs and say there is a short need new motherboard, but I see you looking to fix short this is where best do and mediocre don't do so they lose business. I like people that go the extra mile or do what somebody else said can't be done nice job ACE!. I AM gonna have to fix my laptop by myself thanks.
26:38 ..."This is basic you don't need knowledge, you don't need tools". BWAHAHAHAAAA!!!! Dude you are SOOOOO far ahead of anything I will ever be able to understand and do. I struggle finding the screws to open the cover..... AWESOME. I am happy someone knows this stuff.
When the good things are part of your Nature in the deep of your spirit ,giving to others your knowledge is easy,GOD BLESS PEOPLE LIKE YOU IN THE PAST,PRESENT AND THE ONES TO CAME....THANKS
excellent work mate, I've recently been given a 12month old laptop acer swift 3 and its dead, no power light, no charge light, so I'm learning what i can from you so i can try to diagnose the problem and hopefully fix it. I just dont have a microscope, heat gun, or nice clicking voltimeter like you.....yet....^_^

Hello, I`m watching your videos and I consider them very enlightening! Could you please tell me one thing? What exactly is the liquid you are using on the board between 20:20 and 21:21 of your video? Because I`m wondering isn`t it dangerous - if it`s flammable to have a small explosion as things get really hot while you are testing the board? Also this chemical you are using must not be condactive right? Thank you in advance!
hi, i dont understand one thing, if the transistor was short why do not change it and you look for other components if they short to ground?

nice thanks for responding sow quickly!!! and it was awesome video as always
i hope you have i nice day
I assume the transistor survived the short? It is probably the master on/off control FET?
Just repaired an Asus F75V with this video, put the mosfet out and soldered a bridge - laptop is now fully working, Thanks a lot!
This guy is the perfect example of making a TH-cam channel on what you love . Not a shitty click baiting kind of channel .
First guy i have seen in my entire life who shares knowledge. Well Done 👍👍
Isn't that what teachers are about? Or was I doing something else?
Svaka cast doktore,retki su takvi ljudi koji hoce podeliti znanje sa drugima,sve pohvale i puno srece,veliki pozdrav!
Dobro si rekao!
"This is basic! You don't need knowledge!" says the guy with all the knowledge and experience. Great video...
6:06 "It's a classic one, this is easy to be fixed!" It looks like rocket science to me. Great job!

You did a great job..and that is no basic for me 😓. That is superbb.
checking all the videos, will become basic even for you :)
Thanks 👌

Your in depth explainations in diagnostic pin pointing is very helpfully indeed for a novice, thank you for awesome videos....
Best technician video I found here in TH-cam! Awesome work!
The wisdom in this video is amazing. I am beyond impressed. Bless you for sharing it.
You could say that. 😊👍
This is a good lesson. For anyone who does not have tools but a dead laptop

Thank you master for educating us about the 'SAVAGE WAY'😎 (Brute Force) to find the short.
God bless you...
Awesome tutorial. AFAIK, @23:00 if all 3 caps are in parallel, multimeter won't help bc whole bank is shorted, heat dissipation is the key.
i like the way you explain... its all about basic.. thank you so much..!! i learn so much..!!!
I know nothing about electronic's but found it very easy to understand and follow you, excellent teacher.
You are real expert. All videos are great.
no, just lucky

Wow what a great guy I love watching your videos keep it up you help a lot of people.
I love that dude! :D
He has taken away my fear of trying to fix my mainboard by myself.
What is the liquid that you are using at time 21.22?
It's worth the watch. Sometime's, you just need is skill and patience to solve the problem. Thank you for this video. Greetings from Philippines! I have a HP unit now.

good one mate.. the last past after you solved is LIKE A BOSS.. thumbs up.... :-D
In this video, your actitude & charisma make more great a lesson Sorin, thanks for this.
Thanks man, this was very clear and helpfull!
Nice tips on using lighter fluid to find hot part- would not have thought of that. Easier on finger!
Great video! Your accent makes it even better
What liquid were you putting on the motherboard?
lighter fluid but you can also use isoproponal alcohol
@@martijn4740 why use lighter fluid?
@@stephenzhu7943 has the same cleaning properties as isoproponol alchohol
@@martijn4740 ummm.. I saw sparks at one point. you pour lighter fluid on the motherboard and sparks can't ignite it? That is exactly how a cigarette lighter works. Wick draws up lighter fluid, flick the wheel to generate a spark and the lighter fluid in the wick ignites.

lol - you may be right.
Electronics repair school HAHAHA it sure would not !! 😂😂
What is the liquid and "air in a can" you used to dianose the bad capacitor?
it seems a zippo Lighter fluid fuel
i'm new to the channel and i know nothing about computers but i love these videos
what a video! i have a similar problem with one of my laptop motherboards.very good video so informative
huge thanks to you sir. i'm having the same kind of problem with my laptop. you made me so easy to repair it. thanks
Were is the 3.3 volt and 5volt coming from ? Is there a chip how makes this from the 19volt rail ?
its a power supply (two mosfets, one coil and one chip) for every voltage rail
Electronics repair school hi Sir. What did you pour on 20:17 ? The little can thing. Thanks?
Hi, is zippo lighter petrol
why sir?
Yes Anders, you are right, every rail is created from the 19V main power rail with 2 mosfets, an inductor and a capacitor. Sometimes you'll see more than one power rail output connected to each other, they are outputting the same voltage but they are there for higher current draws.

I had the same problem, thank you. The laptop was other.🙂
BUT SORRY SIR IS THEIR ANY EFFECT IF I DIDN'T REPLACE THE CAPACITOR AFTER REMOVING THE DEAD ONE
