I've seen your video, because I've the same issue on this laptop, and I was lucky to find an competent and honest engineer as you have shown to be, who have searched the defective component, to fix the problem of this motherboard, which isn't cheap; congratulation for your professionalism.
I have searching the internet for weeks and I found nothing, till I stumbled upon your video. I must say man, you're a life saver. Really worried about my laptop. Now I know what the issue might be. Thanks a lot man. Keep up the good work
Woow, this is seriously great find. Finding that almost temperaturelly undisturbed heat spot and pinpoint it as a source of the problem, this is masterfully done
Wow Alex, what a dedication to your craft, working way pass your time to go home, am learning a lot from you, the way you go thru your process of elimination without even knowing what might be the bad component to triple confirming the bad component before replacing it, it does take time to get it fix, for me that's what I've learn, sometime it take me hours, but you are a great source of inperation, thank you so much, good job on this one.
Love your enthusiasm every time you repair a job whether simple or complex... Some of your techniques have been very helpful on trouble shooting some of my issues. Great work and on this laptop motherboard very good eye in finding that discoloration because I wouldn't have found it! I purchase 3 lots of the Amtech Flux but the code didn't work. All good though. I'd buy so much more from you but unfortunately the shipping costs are killing us in Australia. Hopefully customs here won't hold onto the flux for long. Thank you again for what you do.
theyre great if you have the few grand to buy one .. back in the day, or being poor if you will, we had to use alcohol or a can of air sprayed upside down to freeze a spot . in this case i would have taken it outside or tossed into freezer for 5 mins to help find it with thermal cam . i couldnt see it till it was pointed out to me, he has better eyes lol
Hi there , for inject voltage how do we know to which side of the component we have to connect the red probe of Dc power supply ? does it matter ? or we can inject to any side of short component ? thankyou
Nice job Alex,i learn so much of your video’s.too bad i still don’t get anything working 🤣i’ve been working on a Sony Vaio laptop for about 2 weeks still can’t fix the Problem
Awesome brother, i wish you were nearby,recently i got shorted my gl504 cpu fan wires while i was trying to mod the fan while it was on. When short happened it just went shutdown, and never got power nor showing charging 😢. Local repair guys gave up trying. I wish i could get someone who knows what to do ..😢😢😢😢
Good offer on the flux, went to go check it out right after watching the video to get a coupon and buy some and I didn't find the coupon, I still have some but can't pass that deal.
Because he is measuring while it is in circuit, connected with other components, if u take out and measure it will not change. He could also check all mosfets on board, then check all capacitors, then check all resistors... test it self lasts 5 seconds per component anyway and u can do it without having 1000-5000$ equipment, no need to use thermal camera and voltage injector but it can help...
@@orion310591RS It is nice to hear some troubleshooting knowledge. Those sneaky caps in the circuit will confuse testers. Schematics help to understand the readings but are very scarce in the microelectronics world.
Hi Alex, on previous videos you normally removed the component, add flux, prepare putting fresh low melting solder, add the new component, press it down, and remove/smooth any extra soldering, then clean the excess flux with alcohol. This time was quick, took out the component and solder back the new one even without adding solder or pass the tip to re-solder well the connectors. I know we always change procedures as we keep learning in our life, what works yesterday not necessary will work tomorrow. Any special reason to change your previous procedure?
You don't set a value, you set a max valeu for safety because you don't know how many amps the board will take. For example he maybe set a limit of 1.5 A and the board took 1.3. A.
I asked because i have a variable power supply with adjustable amps so that i will know what will i set in the amps when i also inject voltage on my repairs...
Hmm...we need to make a mount for the Thermal camera that will allow it to attach to the microscope mount. So that it can attach to the left or right side of the microscope. That would free up a hand for you when looking for a hot spot. I guess the Thermal cam could have it's own arm to hold it as well, But I figure you do not use the thermal and the microscope to look in different places. You would be looking at the same area on the board with both I would think. And if you did need to move it to a different place the attachment can be made to easily release the Thermal cam from it.
I have a GL504GW which had 3 motherboard replacements, Asus really has terrible quality control. Luckily on the last replacement, I had zero issues and its been working for more than a year now
So odd, I have laptops from Asus working since 2012, another one I bought for my wife working and suffering in our toddler's hands as well as many asus desktop motherboards. I think it might be coincidence or some manufacturing plants might be doing a poor job.
@@thematrixian8710 congratulation on getting "a good one" most asus laptop here just have any random issues, from keyboard, hdd/ssd, board, screen, battery etc
Sir, thanks a lot for ur videos.. i have an awkward annoying question.. Since i got from a previous video that u originate from Lebanon, do u recommend anybody who does what u do in Lebanon?? I have a couple of cases that need someone of ur skill..
Hello, Noob question: I assume that in order to remove the component one would pre-heating at +- 200 degrees Celsius the area with a big nozzle and in a circular motion with a low fan speed for 1min?...then raise the temperature to +-400 degrees Celsius to heat for +-20sec while still making circular motions? And then trying to remove it... I need to find old pcb boards to practice... thanks! :). [Nice job as usual :)]
I just bought my first cheap solder/hotair station from amazon. It's a fairly cheap Chinese one but seems to work only bad reviews say the air wand burns out quickly. Model says LRT 2018D+, bought it to try to fix a new 48v ebike charger that just always says "full" even when not. Will not charge. I seen some shorted caps among other issues on the board. Gonna take apart old boards of stuff i dont care about but work and try to reassemble to working again before moving the caps and stuff on the charger...
Only thing it didnt come with was flux. So wating on some to get here. Mg chemicals noclean flux paste is what I went with for now. As I dont have an ultrasonic or a local place to buy 99.9 ipa for board cleaning with swabs.
Hi Alex my hp notebook light charging on but not light on keyboard or any other place Led Will be orange after battery charged turn solide white My issues is when m trying to turn on the charger light will blink one time and goes back white won't turn on Thank u if u read my comment and give me answer
Greetings of the day!!! Sir, I'm looking for a keyboard for my *Samsung Note NP900X4C*. Can you check in your stock . is it available or not? And can you arrange for me?
I have the exact same laptop and I'm getting a similar problem where while on battery power I can boot up the laptop install windows on it use it but as soon as I plug in the power adapter it immediately starts throwing all sorts of different BSODs. The main one that comes up out of all of them though is memory management. I've tested the ram and it's fine but it's absolutely bizarre that when I plug in the power adapter while the laptop is on it crashes it
That board under the replaced mosfet does not look good. Looks just like it is not soldered on properly because it is damaged. Could be camera view issue, though, I don't know.

I just adore fixing laptops videos. I have watched every signle one in the chanel. The smile in the end is priceless.
you are great repairer. It is always like a birth to get the device back living again :)
I like how Alex gets happy to get laptops working again :D
Even with Thermal Cam, it's still hard to pinpoint shorts... But your skill and experience are just outstanding.
Great video.
It is always a treat to watch your videos...specially when you succed and smile after a good job..hello from Sweden :)
That happy face!! When he know he fixed the product! I love it!🔥🔥🔥

It's always great to watch you troubleshoot & repair laptops! Thank you & early happy holidays! 🤓
after the work done . your smile ......
i am also a mobile repairing shop . n i have that smile too
Another victory for Alex. Good find. More amps would be more temperature but could do more damage. Good thermal camera is worth it's weight in gold.
A jedi at work right there. Well done that man.
I'm thoroughly enjoying your videos, and have been learning alot from you. Keep up the great work 👍
I always like the smile when you show that is working, it's the smile of pride :D i really love it! Keep up the good work man!
Thanks for very good content, you are the best. 😁

Even with Thermal Cam, experience counts to identify weak heat spot. Superb 👍👍
I love that victory smirk after a fix
Besides the experience eyes for finding the slightly discolored area, the importance of a sensible camera to allow that. Nice.
wow nice
Well done mate 🤜🤛
Those thermal cams are utterly essentail.
theyre great if you have the few grand to buy one .. back in the day, or being poor if you will, we had to use alcohol or a can of air sprayed upside down to freeze a spot . in this case i would have taken it outside or tossed into freezer for 5 mins to help find it with thermal cam . i couldnt see it till it was pointed out to me, he has better eyes lol

Hi there , for inject voltage how do we know to which side of the component we have to connect the red probe of Dc power supply ? does it matter ? or we can inject to any side of short component ? thankyou
@@kikihun9726 yes, also in case we have shorted rail, we can inject on any side. If not it shouldn't be hard to trace the polarity and inject.
Another point is you have to start low & no more than 1V because if there's a short to the CPU power rails you could do irrepairable damage.
Well done Alex, nice fault finding.
Hey that's my laptop he's fixing! Very cool, very good service.
Great job. Well done Alex! It was tricky one.
The scratches on that mosfet. Was it by you or caused by a prior repair attempt?
seems like a set up
Great job as always 👍👍
@3:07 the mosfet it shorted, so you go to current sensing resistor to start there? or you just cant inject voltage there?
Very nice fix again Alex keep it up
Where did you get the mosfet replacement from?
Dead motherboard
Another great video. Thank you as always
🇨🇵👍 fast easy and proper . Thanks i always enjoy yours vidéos,
Another great indepth troubleshooting video! I do have a question, with such a low temp difference would it be visible using only alcohol?
As always, nicely done.
Very well said.

شكرا للكاميرا الحراريه...ابداع
I wonder why you haven't mounted your thermal camera so you can do it hands free.

I started watching you recently, you are great, but I have one question: Is your boss assembling and dissasembling things you repair ??
good job mate.
Could you have injected a higher voltage to create more heat, thereby showing a brighter heat spot?
Awesome video! i have a question, why the resistance goes up between gate and source on powermosfet? Greetings from Argentina!
Because he is measuring while it is in circuit, connected with other components, if u take out and measure it will not change.

I thought that was very odd too, usually drowns it in flux before removing chip.
Hi alex. How do you know what mosfet you are going to use as replacment for the bad mosfet?
I have the exact same laptop with the exact same problem. Thank you.
How many Amps are you setting your voltage injection tool when you're injecting 1.2V on the motherboard?
You don't set a value, you set a max valeu for safety because you don't know how many amps the board will take. For example he maybe set a limit of 1.5 A and the board took 1.3. A.
Hi,,,He allready explain that.the amps with that tool Doesnt matter if we inject for à small period of time .i dont now in witch video . Sorry ✌🇲🇫
