man I just discovered your channel like a week or so ago, I have been binge watching your videos. So so good. I was really into electronics when I was younger, like building all types of stuff with 555 timers, jk flip flops, shift registers, caps, etc.. You have lit that fire in me to get back into it. Thank you.

I've spent the past 20+ years performing the same type of repairs as you so I know the amount of experience (plus equipment & tools) it takes to inspect, troubleshoot and repair. Your skills are top notch! Keep up the excellent work.

Happy to see the surgery with naked eye.Looks like a surgeon doing complicated tissue reconditioning , especially with the grinding tools. Thanks for the video Alex. Good luck. After watching your, video .I upgraded my work bench with few other economical tools ,setup etc

Very very nice fix Alex, so not always when the keyboard keys are not working the cause can be found in a broken keyboard... just amazing... thanks a lot for this lesson ;)

As an electronic technician, the wire alignment in minute 7:30 blew my mind. I thought I was watching PORN!!!. Great work! Keep it up, greetings from Argentina!

My friend's computer had same issue and the repair shop told him to buy a new keyboard. Excellent job alex!

Outstanding work as always, I love your work. You inspire me to do micro soldering, because I'm a learning technician in Jamaica, quite young to the work and your videos have taught me a lot. Thanks for being such a open and fair guy, most technicians don't share the methods of the work, especially in such detail. Keep being the great person that you are and may God bless you.

happy and satisfied face after work is priceless, is the best part.

You make that tiny soldering job look easy, a pro for sure. Great video!

Spectacular work. I am always happy when you show new things and ways to repair a faulty product.

It's a great piece of work. So precious and perfect like you do all the time. This fix should get an Oscar. Wow. . All the best. .

Your videos encouraged me to take apart my laptop and work on its motherboard. It was a good experience even though it was not a fix due to dead CPU.

The scope of your knowledge knows no boundaries great video 👍👍👍

At 3:10 there was also small corrosion starting (a minor dot)

BEAUTIFUL job! Congrats! I have a 17r5 and it’s crazy how similar that m17 hoard looks to mine lol I had to replace a USB-C and USB 3.0 port on the board, so disassemble it myself.

Thank you for posting your equipement... totally going to start this as i have a llc dedicated to computer repair.

Amazing repair keep up the great work!

Awesome Alex, those tracers were so tiny, I couldn't have guess it was that, keep up the great work.

it is so nice to see you reaching the ultimate rapair level.

Wow, thank you Alex for this another lesson!

Nice find as normal. Good use of left over strips.

I'm learning alot from your videos

I looked online for many hours trying to find a fix on my personal laptop after multiple keys stopped working, and im sure there are tons of people out there with this same problem that couldnt find any answers. Never would have thought it was a motherboard problem. Cant wait to take mine apart and see if there are any broken traces. Thanks for the video!

Could be a motherboard problem but it's very hard to find people who knows what they are doing. Mostly repair shops usually just make the present situation worse. BTW good luck with your laptop hope it gets fixed

Your work is satisfying 😊

Perfect job congratullations!! hi from Uruguay

Great repair video... nice work Alex

thanks as always for teaching us :)

This was very interesting. Haven't seen that before. Thanks for the video.

Miracle maintenance!

Watching your videos is an addiction !!!

Very interesting. Very strange fault. Well done, class vid as usual!

Really enjoyed it. Keep up the good work

That looked really tricky to do since your working with such small things nicely done 👍🏻

Hi Alex, most EC programmers who work through the keyboard port have the feature to test keyboards. You can see if a key is working or not, stuck or not. But for about 30$ you can also find keyboard testers.

@@kdilac8879 No. Keyboards are "analog" (two circuits are switched together on the keyboard matrix when a key is pressed), which the testers can measure. Touchpads have their own controllers and firmware, so this cannot be easy standardised.

You're a good tech and best salesman

good job mate. nice tools.

Great info! Thanks!

I had the same issue 4 years ago. Thank you

Great work as always.

Probably should have masked the other part you scratched. Seems to be a problem area for corrosion.

the power of the visual inspection. This would have really vapor-locked my brain.

wow even after watching 50+ videos of yours I get to see something new :D I think my laptop keyboard might have the same problem but I already switched to a wireless keyboard so it's not a big deal.

it's very exciting that we don't know whether it's working or not until the end of the video. tanks :)

Brilliant as usual.

cracking fix today alex pad strips are a god send ..

Cool Work alex.

The moment I saw you clear that soldermask with a grinding pen, i went to order one lol. Amazing!

I have the same one, just wondering how those lines were corroded. Nice video 👍👍👍. This is one of the best KZread channels.

Probably its caused by condensed water when you turn on a very cold laptop in a warm room with high humidity..

7:55 Wow, that's amazing!

unique issue (different from all of your video). excellent solutions.

This is very interesting video as it is new thank you so much

Awesome fix

I subbed when you had 26K now subs have gone up 200K

Perfect work

amazing work , great job

I learn new solutions everytime

Good job my friend

Nice job again

Very good job 👏

Love your videos. If I ever have any issues with my laptop, I'll know who to contact.

I can only guess, but it appears those traces were probably made too thin, the coating peeled off, then the traces oxidized to nothing. Slight defect in manufacturing. Honestly I'd of guessed the keyboard wasn't any good before i thought it had this problem... you made the right call.

I love you!!!!!!!!! You are great at your job

Just awesome you are the best

Better than factory, I love it.

Nice fix Alex. Did you have coffee or turn up the play speed? I had to check my settings at the beginning you were talking so fast! Lol! Just playing... Love your content, long may you continue bringing us your knowledge!

Alex, I hope you read my comment. I'm wondering, what you do in cases like that, when the part you ordered is not necessary for repair. Do you keep it in stock, as it might come handy in the future, or do you send it back? I'm wondering what's more sensible from a business standpoint - having that bit of cash "frozen" until somebody comes with compatible laptop and issue or sending it back so you get cash back (minus shipping probably). Keep on good work! 👍

Im always watching your vids

Do you want to hear something funny? I am watching your videos on my phone, and at the minute 4:14 when you finished to grind the surface, i was blowing the screen on my phone to remove dust from grinding, that's how concentrate i was at what you where doing 🤣🤣🤣. Your videos are to captivating man... 😅

great job

Nice video. I wonder why there is corrosion on that part of the board only. Maybe its liquid gets in there, some caps and resistors look a bit corroded too. Do you also clean the whole board for the customer after the repair? Thank you for the video

A simple inspection goes a long way

How thous lines gett corosion maybe liquid damage great job alex as always

Super job 👏

4, very helpful thank’s

Good Job

Its nice when everything goes perfect

Looking at the board and how th alcohol left a visible trace on the board, I bet it was some softdrink or juice on the board that corroded the board, or sweat from a person holding it on their lap for extended periods. Nice fix!

No one says Apple Beats by Dre or Audi Lamborghini. ;D What's with the selective branding disclosure? Love the way you fixed it. 👌 Your new grinder and pads are really proving their value!

There was a time when Alienware was its' own company, so it's pretty common to call them Dell Alienware in the tech industry, as they were actually great before Dell bought them out.

I would have an acer laptop within some days with the same type of problem - wonder it will be faulty keyboard or coroded traces...be in touch, thx for the method! Insane!

Awesome ..

Great job, as always. Impressive fault analysis without circuit diagrams.

Common issue when you keep your laptop on your lap or inside a backpack in the summer. Sweat and moisture finds it's way into the board. I had several issues with my daily driver laptop unti the keyboard was completely gone and that was the end of it. The keyboard is welded to the case so into the bin it went.

Very nice

I have never seen a track corroded like that before. The only damaged tracks I have seen have been caused by over current melting them.

Awesome

Could have been a great surgeon too hands are very steady

Caution! Spoiler alert at 10:44 😄 Your smile is extremly motivating! Please keep up making this fantastic videos!

👍👍👍👍

I also discovered your KZread and I am just a 13 year old kid and understand everything

interesting 👍

The fact you found that so quickly is amazing haha. Fantastic fault finding Alex and the soldering job was even cleaner! Great fix.

The amount of grime on that motherboard is enough proof that the laptop stays in humid environment or has had food eaten on it. Hence the corrosion.

Probably the corrosion was caused by condensed water which happens when you turn on a very cold laptop in a warm and damp room without waiting some time. A failure of multiple keys is often caused by an issue with only one signal line because the keys are connected in a matrix.
