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 ;)
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.
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.
Spectacular work. I am always happy when you show new things and ways to repair a faulty product.
You make that tiny soldering job look easy, a pro for sure. Great video!
My friend's computer had same issue and the repair shop told him to buy a new keyboard. Excellent job alex!
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.
happy and satisfied face after work is priceless, is the best part.
The scope of your knowledge knows no boundaries great video 👍👍👍
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!
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!
Your work is satisfying 😊
Awesome Alex, those tracers were so tiny, I couldn't have guess it was that, keep up the great work.
Wow, thank you Alex for this another lesson!
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.
There is also a touchpad testers? my touchpad is not working and before messing with the board I want a way to test the touchpad
@@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.
@@SiETechNotebookReparatur The touchpad ELAN chip is programmed? If I buy a new chip I have to program it?
@@kdilac8879 you can test the chip using an eeprom programmer like ch341a. You can also use it to dump/save the previous firmware or flash a new one.
@@-.......................- which adapter I need to test this ELAN chip? I have the programmer ch341a
it is so nice to see you reaching the ultimate rapair level.
I'm learning alot from your videos
thanks as always for teaching us :)
Perfect job congratullations!! hi from Uruguay
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
Great repair video... nice work Alex
Como siempre mejor que la fabrica mas duradero, eres el mejor gran admirador suyo y de su trabajo, saludos desde Cuba
Really enjoyed it. Keep up the good work
Nice find as normal. Good use of left over strips.
This was very interesting. Haven't seen that before. Thanks for the video.
Miracle maintenance!
That looked really tricky to do since your working with such small things nicely done 👍🏻
Very interesting. Very strange fault. Well done, class vid as usual!
Great info! Thanks!
good job mate. nice tools.
Great work as always.
At 3:10 there was also small corrosion starting (a minor dot)
Awesome ✌🏻✌🏻✌🏻
Learning a lot from you👍🏻👍🏻👍🏻
Keep it up 🙏🏻🙏🏻🙏🏻
Watching your videos is an addiction !!!
I had the same issue 4 years ago. Thank you
You're a good tech and best salesman
Brilliant as usual.
it's very exciting that we don't know whether it's working or not until the end of the video. tanks :)
Awesome fix
The moment I saw you clear that soldermask with a grinding pen, i went to order one lol. Amazing!
Nice little tool huh?
Perfect work
cracking fix today alex pad strips are a god send ..
This is very interesting video as it is new thank you so much
Cool Work alex.
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.
amazing work , great job
the power of the visual inspection. This would have really vapor-locked my brain.
I have the same one, just wondering how those lines were corroded. Nice video 👍👍👍. This is one of the best CZcams channels.
Probably its caused by condensed water when you turn on a very cold laptop in a warm room with high humidity..
unique issue (different from all of your video). excellent solutions.
Super job 👏
Nice job again
Good job my friend
I learn new solutions everytime
I love you!!!!!!!!! You are great at your job
Just awesome you are the best
Very good job 👏
Love your videos. If I ever have any issues with my laptop, I'll know who to contact.
I subbed when you had 26K
now subs have gone up 200K
great job
Im always watching your vids
Awesome job bro keep rocking bro 👍👍👍
Probably should have masked the other part you scratched. Seems to be a problem area for corrosion.
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
Good Job
7:55 Wow, that's amazing!
Better than factory, I love it.
A simple inspection goes a long way
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!
"Will do something else in the next video".....you sure did! Great job =)
4, very helpful thank’s
Its nice when everything goes perfect
Very nice
Do you have a guide to soldering such small componentry as delicately like that? I can solder wires etc but I wouldn’t know how to make the next step to things as small as this
Awesome ..
Can we use this grinding pen for cutt the Stainless steel which always cover the IC other small components.?
can't belive northbridge 205k subscribers
Hi,
Van you let me know what engraving pen you are using? I need one! Looks like it makes it much simpler to remove top surface on traces. Is it vibrating one? Or rotating one? Thanks in advance!
I wondering how are you charge this repair now like motherboard fix ore the keyboard replacement and what well you do put old or new keyboard?
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... 😅
nice Vedio ☮️👍
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! 👍
What soldering iron u r using and the tip plz
Yes, it happened to me also once for a TV remote. Around 2-3 test pads were totally gone, due to which none of buttons on remote was working. After connecting those, it started working. I thought it could be due to sweat (salty moisture) from hands went inside remote. Not sure how it can happen to a laptop though.
Could be the same sweaty moisture seeping through the keyboard, it is a gaming laptop
if you use a gaming laptop at your legs, you will sweat there and the coolingfan of the laptop sucks in the moisture , the rest you know.
A true gamer takes his lap top everywhere he can to keep up his skills.
Even the toilet.
Bathrooms dripping with condensation and "flush splatter".
Even a "bomb plop" could splash up and cause a moisture hit.
Such is the harried life of a gamer.
@@darkbreed that somewhat makes sense
Awesome
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.
Sir witch soldring iron do you use
How thous lines gett corosion maybe liquid damage great job alex as always
hi,i am missing the big inductor coil next to the charging ic S358 on samsung galaxy 3.7.0 SM-210 and i would like to know its value so i can replace it .can you please help me to get the inductance value of this coil .on the schematics its L505. thanks
interesting 👍
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!
is it possible to use PCB Repair Pens or Conductive Pen instead of pad strip ? thankyou
7:39 Also perfect person for this job
7:36 - that fit was unreal 😱
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.
