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 UA-cam 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.
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'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.
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.
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
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!
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)
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
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.
@@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.
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
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.
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
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
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.
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.
I have an Acer Aspire that won’t power up. I bought it brand new and used it less than a dozen times before it stopped working. Is this an inherent problem with Acer products??
So i have fluke `17B+ but it does not beep on diod mode when there is a short on cap and mosfet. what readings should i be getting if there is a short?
You are truly amazing my friend I have learned a lot from your videos and currently trying to locate a fault on a Scania Coo7 ecu , the vehicle doesn't see it at all 🤬 I have a donor ECU exactly the same that is perfect ,so I am just comparing voltages and they not the same 🤣 that's as far as I got
Great as usal. I have a question. My multimeter doens't do a long beep in diode mode when a short is reached. What voltage drop should I read to understand that i have a short? Thank you
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"...
If i put Multimeter in continous mode and test both ends of a Resistor and it beeps, does it mean it is bad? Or does it have to beep because it is equal to a fuse?
Great video, thank you! There was one question, you mention a voltage drop indicating no short circiut. If I understand correctly you did not have the 19v power connected. How then can you measure a voltage drop?
Hi guys, I have got this mobo on bench, no power at all...19V not passing first mosfet, no short found on second mosfet output. Changed charging IC, the same, BQ24780s, ACDET-1V, comparing to schematic, should be 16,4V. Any idea? Many thanks...
I think on that one with the bad connector I would have set it aside until the rest of the boards were worked on. Then if there is a no fix in there steal the connector from it.

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 :)

super job

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 :)

I love the pride this guy has in his work.
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.

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.
I love it when you get happy when the repairs go proper
3 repairs in one video???? this is awesome! please do more like this. :D
yeah i agree its so entertaining
Awesome!!! Better than factory
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!

You are really gifted my Bro and i do enjoy on how you explain faulty tracing . God Bless you !!!!
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.
My love for electronics makes me love watching your beautiful videos everyday..I learn a lot all the time..

سمعتك قلت " اعطيني"
اخي نتا اسطورة الله يبارك
I know it
Alex, you rock! Keep up the great work!
I love watching a master at work
Easy way to find short is apply IPA and inject your 1V source and watch the shorted component dry up the IPA instantly 👍
My Acer has the same issue. I will tell the Technician to watch your video, Thanks so much for your videos!
Nice! Will follow these steps on a $20 Acer on its way with no power.
You make it look so easy ! But for real it's hard to do . Keep up the good work .from the Netherlands 🇳🇱 grtzz
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.
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 :)
Excellent job like always. Hi from Uruguay
Wow a two for one. Thanks for that. Correction...3?!? Wow. You are being generous in this video.
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.
alex spoiling us with long episode today. :)
Good work brother always enjoy the new videos and gaining some deeper knowledge about how pcb's function.
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.
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

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...

Great Job Alex , you are the best, I realy like your videos and your website is very nice too, congratulations.
excellent video, thanks for sharing your knowledge, I always learn something new with you. Greetings from Mexico City
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!
Thank you for sharing your knowledge. Amazing job! More power..
20:28 "and 1 infested" - you crack me up!
I cant stop watching these videos...
May be the power adapter went in safe mode and required a reset? 🤔

Great job, keep it up Alex!
Thank you........!for the lots of knowledge.Godspeed!
for the 3rd laptop may be your charger is still in protection mode !!??
You are doing great . I enjoy the videos. 🌷
Was hoping you can fix the connector, but some things are impossible, or taking too much time

I need help please which ones are negative and postive these ports are crap repair and im wanting to hard wire the charger to the motherboard
AWESOME VIDEO 3 LAPPY REPAIRED IN 1 VIDEO, LIKE HITTING A JACKPOT. HAPPY DIWALI BROTHER. LOVE FROM INDIA
Thanks! For sharing your knowledge.
How did you know which value spare cap to use? Just wondering, did you have schematics for this device?
use to have to touch everything or use cold spray to see what was hot.
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
Great as usal. I have a question. My multimeter doens't do a long beep in diode mode when a short is reached. What voltage drop should I read to understand that i have a short? Thank you
I have an Acer aspire 7736zg with the dame problem, when i push the Power buton i have Power but the screen doesn t start..
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"...
your way of troubleshooting is very smart !!!
Where you can get circuit diagram for these Acer chips ?
impeccable
super video , one more for the coffee break
WELL DONE !!
If i put Multimeter in continous mode and test both ends of a Resistor and it beeps, does it mean it is bad? Or does it have to beep because it is equal to a fuse?
Alex. What does it mean when you're ts-30a beeps at you every time you try to inject? Thanks
It beeps to indicate a short. You may be able to turn it off from setting. I'll have to look into it.
Great work as usual
Great video, thank you! There was one question, you mention a voltage drop indicating no short circiut. If I understand correctly you did not have the 19v power connected. How then can you measure a voltage drop?
How can you know the value of the capacitor if it’s blown up?
A great teaching exercise!
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.
Easy money, love your work your my idol ..
how do you know what value capacitor to replace with please?
Loving this....same laptop(s) different problems =)
