As a retired Electronics Tech, I am still learning every day from videos like yours. There is a huge sense of accomplishment in solving the "Puzzle" that a repair actually is. Even just watching You troubleshoot a complex electronic device in a systematic, and chronological approach brings a spark of joy to my life. Thank You so much for freely sharing your knowledge with the RUclips World. Most enjoyable. Keep up the good work.
I don't know why, but just watching your videos makes me smile. Seeing electronics being fixed by just a capacitor replacement just really feels good. You're saving one more laptop from going to the e-waste pile at a time.
i've watched almost all of your video and im able to repair my shorted lenovo laptop due to blown capacitor. Thanks even though i have a little knowledge on stuff like this. It saved me a lot of money.
Im a self taught person who likes fixing laptops and im learning alot from you. Thanks alot for sharing your knowledge. May God continuously bless you. 🙏🙏🙏
I wish to work on a shop like this..I'm a former vaio technician with 5 years experience but now I'm doing only cellphones..I'm really jealous with this guy..i miss doing laptop..i watched all videos on this channel..love from Philippines.
Thirteen, thirty-three Acer laptops for repair; it doesn't matter because we love to watch you troubleshoot and fix as many faulty laptops as possible. The more the merrier. Love it!
I rarely comment on videos but this one was really enjoyable thank you. I could watch you fix all 14 including the roach board. OK especially the roach board but you have to set up a second camera to catch your facial expressions 😂
Hello sir love all your laptop repair video tbh I've just finished my first laptop repair with no power i fix it using voltage injection and the laptop now working thanks to you I've learned a lot more power and God bless
Been fixing electrical items. It is so much fun. Fixed an Xbox, video capture card and a TV lately. Working on an old Discman just for fun. It is rusty. The switches are bad. Cleaned them with lighter fluid and now the switches work. I feel I have some faulty caps on the power rail. I am only getting 2 volts of what I expect should be a 3 volt rail. Thanks for posting.
I have following your channel for long time ago and I really enjoy each one of your videos, I just would like to say you, thank you to share your expertise and knowledge to all of us. Regards
I have tech experience in troubleshooting however I had to start at power supplies and connecters first to trace current, and voltages at the source, your methods have been great for this video, by knowing common discrepancies first hand . saving time. great video. we used (face milking)
@@NorthridgeFix possible to throw it into an ultrasonic cleaner first? We use one with other components, although I haven’t tried a laptop mobo. That one does seem fairly small.
Hi Alex! There must be a more ergonomic way to store your voltage injection and Fluke cables so you don't have to pick them from the ground. Perhabs some clamps on the side of the back bench? Love the videos!! Greetings from the Netherlands.
I store my cables hanging off the bench too. Anything else, they get tangled after a couple of uses. This way, they get dropped out straight and drawn up again, frees them up every time you pick them up.
14:21 damn freaking god you legend just after seeing this I saw my old HP laptop which didn't charge only ran on battery and its has the same issue I remember inserting the charger forcefully while it was putting a lot of resistance
It's nice to have so many of the same to be able to get readings from different components. Roach infestation lol. 2e had one full of maggots, we refused to work on it. Same as toilet damage, we refuse those too.
With my PINECIL soldering iron and desolder braid, started repairing broken gaming mice. Bought broken mice each for €10 and nearly sold 8 Logitech g Pro wireless for each €80 modded. Thanks for the inspiration and a bit of side income to buy my very own rework station.
When I used to work in electronics, my boss told me if we find roaches in a devise ,,bring a bag , put the unit in , call the customer to pick up his unit and not to come back at the shop !
Thank you very much for showing your professionalism in your videos. I would like to know in this case how you know the value of the capacitor to be replaced.Greetings from Spain
I would like to know what brand and model thermal camera you are using or at least what pixel resolution is sufficient for finding faulty parts with a thermal camera.
Would it help to put the nasty board in the ultrasonic cleaner ? I wouldn't like to work on a nasty board eighter. Nice to see you enjoy every fix, good work Alex!
Doing that would give you the marvelous new problem of a nasty roach-covered ultrasonic cleaner to deal with. See also the reference manual titled "Dr. Seuss's The Cat in the Hat comes back"...
I tried several repair places to get a laptop repaired but didn't have a replacement connector, or a bad donor board. Wound up sending it to the company I bought it from (system 76). In the end repair costs I would have been better off just to cut my losses and buy a new laptop. A $400 repair for less than a $5 connector that I could not get. If I need another repair I'll try and contact you.
Hi there , 03:09 , you said you didn't touch the amps or current on the power supply ? what do you mean ? you mean your current or amps on your power supply is zero 0 ?if your power supply set on 10 amps or current your component will be blow up . please explain more in your next video ? thnx
how do you know what value capacitor you have to use? is there any place I can get motherboard circuit diagrams I really appreciate it if please just show me the right path thank you so much
Repairing electronics is like Maths, the more you do the more you can do it quickly its really disappointing that sometimes people disregard your experience :(
I really enjoy your troubleshooting and I find it very interesting. What are the tongs that you used to Resolder the cap called? Where can I get that to solder some SMDs that I have.
I love to watch your video here at my work while no customer around here at Lenovo store, I just wondering , is Lenovo brand is very seldom you receive for repair? Thanks you very much Alex
I love your workbench, its exactly how mine was when i was working in electronics. What i dont get is how you are able to know what Farad value those caps are, Are you able to get a schematic from the manufacture?
Very crazy how many laptops had issues at the same time, very strange, another strange thing is why this guy have 13 units of the same laptop..was it from a company?
@@HazeAnderson Although I can definitely imagine a bug zapped by high anode voltage causing havoc in a vacuum tube based computer, the first actual bug was a dead moth that disrupted relay contacts in the Harvard Mark II. That computer did his calculations with high-speed relays. Those computers used less (especially stand-by) energy than vacuum based computers, but were also a lot slower. The Harvard Mark II could do 8 additions in a second. A contemporary vacuum tube based computer, the ENIAC, could do 5000 additions per second.

what i wish he explained is how he knew the Farad value of that capacitor, Capacitors come in an incredibly wide variety of values.
@@islandwills2778 One cap of the same size does the trick .. as we have seen time and time again :)
i've watched almost all of your video and im able to repair my shorted lenovo laptop due to blown capacitor. Thanks even though i have a little knowledge on stuff like this. It saved me a lot of money.
The money you would of spent on repair you spent it on equipment to fix things yourself 👌
@@dafalzonAUS That's a good idea sir because I only barrow basic tools from my cousin cause I dont have one 😢 .
@@onurolce try to inject voltage on the board, what ia your problem, i can maybe help, what laptop/model :)
Im a self taught person who likes fixing laptops and im learning alot from you. Thanks alot for sharing your knowledge. May God continuously bless you. 🙏🙏🙏

You can simulate the volt injector tool with any stabilized power supply that can be regulated and limited in current

Always enjoy watching how you track down faults on different devices with the explanation. Thank you for sharing your knowledge & experience.
3 repairs in one video???? this is awesome! please do more like this. :D
yeah i agree its so entertaining
Awesome!!! Better than factory
I love it when you get happy when the repairs go proper
I rarely comment on videos but this one was really enjoyable thank you. I could watch you fix all 14 including the roach board. OK especially the roach board but you have to set up a second camera to catch your facial expressions 😂
I loved that video. Same boards different issues. I could see all the 13 boards. Great job!
I agree I was sad when he stopped. Repetition like that makes for great learning.
Hello sir love all your laptop repair video tbh I've just finished my first laptop repair with no power i fix it using voltage injection and the laptop now working thanks to you I've learned a lot more power and God bless
You are motivating me to start work which I left 7 years ago. To be honest, I learnt so many things watching your vidoes. Kudos!
Why you said, "Hmm? And it's deep, too." I laughed because it reminded me of an old Richard Pryor joke. If you know, you know. Great job as always.
You are really gifted my Bro and i do enjoy on how you explain faulty tracing . God Bless you !!!!
My love for electronics makes me love watching your beautiful videos everyday..I learn a lot all the time..

15:25 bend the tip of a needle 90 degree and use it as a hook to grep under the contact to bend it up again.
You are better than factory my friend. God bless you
Excellent long video with many repairs would love more of these. Feels like it should never end 🥶

20:28 "and 1 infested" - you crack me up!
Alex, you rock! Keep up the great work!
Fantastic video. Those are ours, lol. Sorry about the buggy one, we didn't look close enough.
No Worries.. We're finish the rest soon
@@NorthridgeFix possible to throw it into an ultrasonic cleaner first? We use one with other components, although I haven’t tried a laptop mobo. That one does seem fairly small.
alex spoiling us with long episode today. :)
You make it look so easy ! But for real it's hard to do . Keep up the good work .from the Netherlands 🇳🇱 grtzz
Wow a two for one. Thanks for that. Correction...3?!? Wow. You are being generous in this video.

Der Profi - wie immer am Werk !
My Acer has the same issue. I will tell the Technician to watch your video, Thanks so much for your videos!
When you is a Boss in repairs good job again
I’m just wondering why these boards have so often failed. Is it a design or engineering problem or what? What are your thoughts? Love your show!
14:21 damn freaking god you legend just after seeing this I saw my old HP laptop which didn't charge only ran on battery and its has the same issue I remember inserting the charger forcefully while it was putting a lot of resistance
Nice! Will follow these steps on a $20 Acer on its way with no power.
You must be the king of resurrection for these types of motherboards!
Good work brother always enjoy the new videos and gaining some deeper knowledge about how pcb's function.
Excellent job like always. Hi from Uruguay
It's nice to have so many of the same to be able to get readings from different components. Roach infestation lol. 2e had one full of maggots, we refused to work on it. Same as toilet damage, we refuse those too.
Great Job Alex , you are the best, I realy like your videos and your website is very nice too, congratulations.
I cant stop watching these videos...
May be the power adapter went in safe mode and required a reset? 🤔
With my PINECIL soldering iron and desolder braid, started repairing broken gaming mice. Bought broken mice each for €10 and nearly sold 8 Logitech g Pro wireless for each €80 modded. Thanks for the inspiration and a bit of side income to buy my very own rework station.
Hmmm i might try this i’m gonna do broken controllers first tho i already do broken joycon analogs because you don’t have to solder to replace it
excellent video, thanks for sharing your knowledge, I always learn something new with you. Greetings from Mexico City
Acer only switched to this small connector recently. As a long time Acer user, I have many old 19v chargers now that I cannot use...
Easy way to find short is apply IPA and inject your 1V source and watch the shorted component dry up the IPA instantly 👍
Hi, I had the same issue as the 2nd board... a bended metal inside the power plug. Acer at their best! Thanks for the tip.
for the 3rd laptop may be your charger is still in protection mode !!??
When I used to work in electronics, my boss told me if we find roaches in a devise ,,bring a bag , put the unit in , call the customer to pick up his unit and not to come back at the shop !
I am impressed every time. How to determine size of defective cap
Thank you for sharing your knowledge. Amazing job! More power..
Thank you very much for showing your professionalism in your videos. I would like to know in this case how you know the value of the capacitor to be replaced.Greetings from Spain
I use really small screws to pull stuff out or back.
I would like to know what brand and model thermal camera you are using or at least what pixel resolution is sufficient for finding faulty parts with a thermal camera.
UNI-T UTi260B thermal Camera
How did you know which value spare cap to use? Just wondering, did you have schematics for this device?
You are doing great . I enjoy the videos. 🌷
The voltage injector is like a spare tire --- one should not drive on it all day and all week. (current limiting)
I would say it's an air pump for the car tires to find the leak on the tire then you patch it.
what a awsome guy he is ...really great work
Would it help to put the nasty board in the ultrasonic cleaner ? I wouldn't like to work on a nasty board eighter. Nice to see you enjoy every fix, good work Alex!
Doing that would give you the marvelous new problem of a nasty roach-covered ultrasonic cleaner to deal with. See also the reference manual titled "Dr. Seuss's The Cat in the Hat comes back"...
Nice work, let us know if you did the infested one, taking your health precautions as well.
your way of troubleshooting is very smart !!!
Where you can get circuit diagram for these Acer chips ?
Good
Can you took about your microscope or if you had do could you write the link

super video , one more for the coffee break
Hi there , 03:09 , you said you didn't touch the amps or current on the power supply ? what do you mean ? you mean your current or amps on your power supply is zero 0 ?if your power supply set on 10 amps or current your component will be blow up . please explain more in your next video ? thnx
use to have to touch everything or use cold spray to see what was hot.
I enjoy watching your videos. you make reapir business looks so easy. keep going
Great job, keep it up Alex!
Maybe a stand for the IR Camera would be a good idea
how do you know what value capacitor you have to use? is there any place I can get motherboard circuit diagrams I really appreciate it if please just show me the right path thank you so much
One cap of the same size does the trick .. as we have seen time and time again :)
Repairing electronics is like Maths, the more you do the more you can do it quickly its really disappointing that sometimes people disregard your experience :(
Maths?
Keep it up guys, I really learn a lot , thank you,
What temps do you use for your soldering iron?
Damn triple round what a boss!
Niceeeeee
Thank you........!for the lots of knowledge.Godspeed!
I really enjoy your troubleshooting and I find it very interesting. What are the tongs that you used to Resolder the cap called? Where can I get that to solder some SMDs that I have.
do you have a link to the probes you use for finding the shorts ? they look very good to me. ty
AWESOME VIDEO 3 LAPPY REPAIRED IN 1 VIDEO, LIKE HITTING A JACKPOT. HAPPY DIWALI BROTHER. LOVE FROM INDIA
Was hoping you can fix the connector, but some things are impossible, or taking too much time
Are those laptops light duty type? The motherboards look sorta small!
Loving this....same laptop(s) different problems =)
I love to watch your video here at my work while no customer around here at Lenovo store, I just wondering , is Lenovo brand is very seldom you receive for repair?

ما شاء الله. بورك فيك و في أقرباءك
Can a AA battery at 1.5v work the same with the injector tool you use? Thanks.
i think the amps on an AA battery is low which could be unsafe
about the cockroach-infested one, should you charge them more if you decided to work on it?
WELL DONE !!
A full video with those is worthy 😁
What do you do when a gate is shorted to ground?
Very crazy how many laptops had issues at the same time, very strange, another strange thing is why this guy have 13 units of the same laptop..was it from a company?
what was the infestation?
