I am studying Computer technician in my country and I'm learning a lot from this guy! He shows a lot of techniques in identifying common issues and some I haven't encountered yet. I gain a lot of wisdom and knowledge by simply watching his videos. Kudos to you sir!
I've been doing electronics work since I was a kid going with my dad to his TV repair shop, spent 20 years in the military as a radio tech, and am now nearly finished with two associates degrees in electronics/electro-mechanical systems, and I learn something new EVERY TIME I watch one of your videos. Love your work and channel my friend! Nice work.
WTF? u work 20years with electronic and have two degree, but u did not know what knew somebody with BASIC electronic knowing? Did u sleep all your work and two degrees?
This guy really knows what he is doing.Unlike other guys on yt that do it by trial and error ,or some others that already tested the device before making the vid and knew the issue but are acting like they didnt. Keep up the good work, I am learning a lot from you.
the amount of calls coming from the customer being so vague about their laptops, imagine the amount of work he takes a day lol. genuinely love this type of work
This was hands down the most informative, clear, understandable tutori for throunleshooting motherboard issues. Thank you so very much sir, you do awesome work!
Thank you for your very clear explanations where you talk to people like they don't know anything and you repeat the concept a few times so they "get it." Some people teach like the student knows what they know, and it's hard to follow. I have fixed analog electronics in the past but this video really gave me a much clearer understanding of how to go about it on these digital laptop circuits with these microscopic surface mount components!
good day alex thank you for adding words on the screen when you are repairing a device,my son kyrian venter is deaf and he cant hear,so now its much better for him to follow your prestine work,thank you for that we are from south africa in cape town strandfontein,we watched all you videos so far and gained alot of knowledge from you,we appriciate the effort you put in to this channel,a shout out from me arrie and kyrian from cape town south africa
Nice guess on the bad capacitor! It looked a little bit de-laminated, but hardly discernible even with a microscope. You could have replaced it with a 10nF capacitor, just to provide some local noise filtering. It is a conservative value, as 100nF is a typical value for those.
HELLO NORTH! Am an avid Subscriber, you are my first 'Go to' when diagnosing PC issues! I recently built a new Computer in my old Tower with a new Raidmax Vampire 1000W 80 Plus Gold Power Supply, an MSI Z390-A PRO Motherboard with an Intel Pentium Gold Processor G5400 CPU @ 3.7GHz! Next added 64.0 GB DDR4 3200 Ram! Also a ZOTAC GAMING GeForce GTX 1 Video Card! Recently upgraded all my HHD's with an Intel 660p Series M.2 1 TB SSD Drive C and two WD I TB internal SSD's! My Computer now boots up completely for a cold start in 30 seconds!!!! (Once in a while when I turn it on, it Boots into the Bios Screen)!!!(But when I wont to boot into Bios, no matter what key combination I press it wont go into Bios on Command)! Windows will not display on my Digital Monitor but I can see the Bios Screen on another HDMI Output to my 32 inch TV! Am running XMP Mode and Gaming Mode on the MSI along with allocating 3/4 of my Ram to Process my Adobe Premiere 2022! My Question is: How do I get the computer to Boot into Windows EVERY TIME? And secondly, How do I get my computer to boot into Bios on command?
Very very helpful video. I found the schematics of my laptop (ACER) on Internet for 5$. 1 diode and 2 capacitors in short ... now repaired. Thks a lot.
Great job. By seeing this video I have fixed my college Asus laptop which was not turning On even with battery or charger. I just removed one tiny mosfet near by charging port. I found that surrounded area capacitors shows short to ground. Once I removed tiny mosfet then short has gone. I do not have a same mosfet so I decided to jumper its drain and source pins. After I assembled everything I checked laptop and wola it's working fine and charging too. Thanks for guiding through your videos.
@@barbara82589 I knew that if the situation happens again then possibly another mosfet would fry also and could damage further towards supply rail or power management circuitry. For that reason I have added 2 Amp smd fuse in series leading to mosfet. So in case if charger cable short again from its positive to ground or laptop draws 2 Ampare because of anything wrong with charger then 2 Amp smd fuse will below instead of whole power management circuit goes blow.
What ASUS model do you have? Seems to be a somewhat frequent ASUS problem. Mine is a Q324U. I wish they would have used a harness connector for jack component instead of solder type, easier to test and swap out for those of us without soldering skills
@@barbara82589 I'm sorry I don't remember the exact model now but I will update you after ask my colleague. But I'm not pretty sure that it's frequent problem with Asus laptops. In our case charger cable was torn and by mistake it was joined reversed polarity. Once he connected charger just after cable repair then within 2 seconds laptop shuts down by itself. Some laptops I have found small charger port PCB and some harness connects that PCB to Mainboard. So repair might be simple or requires replacement of charging port PCB only.
Thanks so much for the explanations! Had my laptop fixed at a local shop and having no knowledge about circuits I was dumbfounded with his lecture about mosfets and capacitors... This video really helped me understand. Thank you!
@@NorthridgeFix Sir... I have a question and I really need your answer based on your experience. I was using my netbook for about 5 minutes after that it suddenly turning off and smoke coming out of the charging port, I immediately unplugged the adapter from the netbook. After that, I waited 1 hour and tried plugging the adapter back just to see if the charging port indicator light is still on and yes it's still on but I'm afraid to turn on the netbook. my question is... does my netbook still have a chance that there will be no serious damage to its components or not?? sorry about my english ...
Just my 2cts : when using FLIR - do not use laptop PSU, it will shut down, use a lab PSU instead and start with 1-2 Volts, this will give you about 3 Watts of heat on your defect cap, which will show nicely on your FLIR.
@@user-ty2uz4gb7v completely short, ZERO ohm. Meter shows near about 0.23ohm. ALL laptops that I fixed with ZERO ohm caps over 1.2v, 3.3v or 5.0v lines, capacitors never warmed.
Today I just got luck to visit your video, video was good. I haven't watched the way you have explained over the youtube. Something very correctly understandable. I think your explanation way will definitely make me to watch your all videos. Keep it up. It's all new to me. Thanks
Wow wat an explanation n I have total respect to this guy the way he explain his theory n does practical on electronics. This guy is an electronic encyclopedia
I actually have that electricity feeder. Just short one flir Camara got the whole kit to start fixing again, your videos are a great refresh update on new methods
Nice informative tutorial but here is a thought: Voltage injecting 19v on a faulty board seems really dangerous. It could damage even more. Why not hooking it up to an external power supply, limit the voltage to 5v and limit the current as well. This will prevent the inrush limiter to kick in and you can still use the flir camera. What do you think?
Awesome. Your videos are short and brief, whilst containing the crucial skills and knowledge in pinpointing the exact issue and solving it. I've learnt alot in such a short time in comparison to other 1 hour long videos from other uploaders. Because of that, I've subscribed.
First of all, let me introduce myself. I"m Jadi from Indonesia as a Begginner PC/Laptop Technician. Btw,Thank U to share the Valuable Technical On Repaire the Laptop.
That was such a neat piece of work, you remind me of my computer maintenance teacher, he's so genious like you. Thank you for sharing your experiences.
Great job as always, keep up the good work, and thanks for the thorough explanations! I am always learning alot from you and always look forward to my "daily lesson". Regards
That's because laptops have all the same principal. 2 Mosfets in the input, various stepdown converters (with 2 mosfets, various capacitors, 1 inductor and a driver) and so on, they are all alike. If you want to know more about this follow "Electronics Repair School" channel, it is pretty similar to this one. @NorthridgeFix Loved this channel subscribed!
Your solder skills are as impressive as your diagnostics. And you take pride in your work. Thanks. Have a few “dead” old boards am going to play with but only for learning. Plus keeps me from HDL wife keeps piling on 😏
Thanks! I have ASUS ZenBook 14 UM431 and same problem - device won't charge, won't power up. Now battery is dead and I unable to use laptop. Using your video, I seems found Capacitor witch is shorted. Now I'm waiting for air "soldering iron" to arrive to fix the capacitor or keep looking for dead IC...
You can inject 19V to the 19V rail w/o damaging but you MUST use a power supply with variable current limit, cranking the current slowly up. The thermo camera is a good idea if you have it, otherwise use your fingertip carefully not to burn yourself. Using serial connected 24V or 2x12V automotive light bulbs for current limit is a cheap solution if you do not have a power supply with variable current control. The bulbs can be 15W, 25W, 45W 55W depending on the desired current.
that´s what i do,i'm just a small time hobbyist. edit: besides monitoring the Amps thru a second multimeter,on Amps, they can also be *seen* on the more or less brightness of the bulbs, from 5W or less to 45W
I can learn a somethng here. This not 100% can be work for all laptop. Which mean, it can be different for another laptops case but I understand every what his said and we need to check every parts with the multitester. The conclusion is, check the shortage, if components is a different than usual from another for the same type like hotter, no power or discolored, mean that was the suspect. We need to remove or replace it then plug back the power source then see how it goes. Thank you for sharing :)
This is eye opening.... I got similar problem, now i know.. not all the all the cap need to change.. If Shorted.. There is should be one cause everything..
Hi, You can put a little bit of flux on a suspected short component and draw the current; if that is short the flux will vaporize. This is also a manual method of testing short component like puting on a finger and feel the heat as we know this is a low voltage circuit. Good luck..
I think it would be ok to apply low voltage/cc directly to these suspicious caps, would make it easier to pinpoint the shorted part. Also it looks like you chipped off a bit of capacitor at 9:39
Very intuitive diagnosing protocol. Impressive. I, too, have a Asus rog gl552vw with puzzling symptoms: - when power connected, the front light for power and battery charge are on but it doesn't boot - if only on battery, no lights on, no boot - when I leave it, plugged or not, the area on the left of the pad becomes quite hot until I remove the power cord and the battery... Any idea, somebody ?... Thank you
Sir you have really good instruments & tools for repairing, & process of work is really nice,but you can fix this at only 2 minutes by injecting volt with high amp to the second mosfet & detect faulty capacitor by hand... Sorry if i hurt you... Thanks
Great explanation! I wonder which liquid you use to desolder those smd mosfets? My heater would be at 330 degree and the fan on level 2 but not pleased.
Great video! While I've been building PCs for 20+ years, I have no experience in electronic repairs, what are you applying at 4:40? Flux? Heat absorbing gel? Would an ESR meter not help in finding the faulty cap?
Thank you nice work. Just wondering how the laptop ended with two problems at once. The charging port plus filter capacitor. Was it the bad charging port that damaged the filter?
Thanks for the information In my own case I was working with my Asus and as soon I plug in my PC game pad to play games for relaxation after working on Archicad and closing for some hours, it just went of instantly as the usb is pluged, including charging indicator and other lights I have removed the battery and held the power button for 1-2 mins to see rest by discharging any power on board, the tried powering back but not positive result
I have a hp omen laptop that stopped charging a few months ago. After a month or so, it just started charging again until I took cable out. After plugging in it would just split sec go orange charge then white, no charge. After another month, same thing again. I got a brand new genuine hp 230w charger and still same thing. Bought a brand new battery. Still same thing. Bought a brand new power jack and still same. If I use my older laptop 90w charger in this gaming one, it works and charges up. Plug the original 230w and no charge. If I remove battery it won't power on, just flickers a white light every time you try powering on. Put the 90w charger in and it works without battery
This video is awesome! Thanks for sharing your job. One question, how many celsius degreess do you normally use for removing/adding smd components on the motherboard? :)
Freaking awesome man! I now wonder if these strix's inherently have this issue or are common to result in a blown cap, starting with a weak charging port receptacle. I had the same thing happen to mine... Thanks to your video, I have hope in troubleshooting/fixing this.
What is that you poured on to remove the mospet if that's how you spell it is that some sort of flux? Like 5 minutes into the video, I see no smoke. This video is excellent thank you.

Ny guess its cos he used too much solder on the mosfets. Sure the pins are the same but you want a proper finish.
probably the competition hating on the Professor and Big Boss lol
Just wanted to say thanks for all the videos. They are very informative and the way you explain things really resonates with me.
I like how you explain mosfet work, and what causing short by capacitor and resistor not causing short. Keep smile :)

Hi! your video on troubleshooting is easy to understand and get more knowledge on repairs, thank you and continue upload more videos.
Hi,
You can put a little bit of flux on a suspected short component and draw the current; if that is short the flux will vaporize. This is also a manual method of testing short component like puting on a finger and feel the heat as we know this is a low voltage circuit. Good luck..

I have a hp omen laptop that stopped charging a few months ago. After a month or so, it just started charging again until I took cable out. After plugging in it would just split sec go orange charge then white, no charge.
After another month, same thing again.
I got a brand new genuine hp 230w charger and still same thing. Bought a brand new battery. Still same thing. Bought a brand new power jack and still same. If I use my older laptop 90w charger in this gaming one, it works and charges up. Plug the original 230w and no charge. If I remove battery it won't power on, just flickers a white light every time you try powering on. Put the 90w charger in and it works without battery
This video is awesome! Thanks for sharing your job. One question, how many celsius degreess do you normally use for removing/adding smd components on the motherboard? :)
Freaking awesome man! I now wonder if these strix's inherently have this issue or are common to result in a blown cap, starting with a weak charging port receptacle. I had the same thing happen to mine... Thanks to your video, I have hope in troubleshooting/fixing this.
What is that you poured on to remove the mospet if that's how you spell it is that some sort of flux? Like 5 minutes into the video, I see no smoke. This video is excellent thank you.
Very good analysis sharp, quick and brief.
Impressive! Informative, with the minimum of useless chatter.
Thumbs up and subscribed.
