Finally Subscribed After a Year of Electronics Lessons !! (Lol), You are my MASTER TEACHER, you have given me confidence in fixing electronics and not electrocuting myself with 19v, (Lol), Greetings from Westham East London. Thx. You are an ASSET to the Human Race.
Hi Sorin We watch with awe , twenty years of experience is impossible to teach in two years with such a varied array of faults, I love the honesty of your reasoning your videos are a pleasure to watch, . please put screws in some old lids or something, we can't stop watching you.
I can see that you are from country - just like me - where we learned to repair everything and under any conditions. Just an old honest school. Most young electronics wouldn't do that. They'd rather wait for the delivery of the new component. Or it would declare the device irreparable. Greetings from the Czech Republic.
I can only imagine how many people have thrown away similar PC's entirely, only because of a similar fault that can be narrowed down to something as simple as a defective power button. All of those wasted motherboards, displays, hard drives, memory etc in the trash.. very sad!!
I like how he sounds like his interacting with the viewer and has patience to actually teach how the components work and explaines in detail lots of the strategies and techniques to solve the issue. Thanks alot for your videos my friend really teaches me lots of things to solve better at my own issues in my circuits aside from the fun doing it and solving the issues
It's not boring Sorin, it's very interesting and a refreshing change from a charger port fault. Have to admit, I called it from the beginning, once 3.3v was confirmed and 0v at the power button, I said power button sticking down :) Personally, before removing the button, I would have removed the board and soaked that end in a cap full of alcohol for a couple of minutes first.
Your videos are awesome. Your accent is cool. I've never seen an esr meter on your bench. You make the repair look easy. It is not really hard, too, but finding components to for replacement is really a challenge in Brazil. I can import from China but it takes ages to get to me. I've learned a lot from you. Thanks for sharing your knowledge and time. Some people out here really appreciate it.
Sorin: i can remove this capacitor..... *emoves with tweezer* me: hahaha Soring: i can remove this resistor..... *removes with multimiter* me: hahahahahaha Sorin: i can remove this power button..... me: remove it with your multimeter hahahahaha iits funny how you consider those things as nothing for you, me i am extremely afraid of reming something with the tweezer from someone's computer, i am afraid of random things to happen so i end up doing two works instead of the original problem, it happened to me many times but now i take the lowest risk i can.
I've noticed that the more experience you have - less you care, because you know exactly what you are doing and your muscle memory is definitely there to help you, when you don't have a lot of experience you try to make everything professionally and oddly enough - bad shit happens even if you are doing everything right... But yeah, his methods are so old school... petrol, enjoying rosin smell, while all the new boys are using fancy stuff to pull away the smoke...our Sorin is just enjoying the moment... That's proper sick...
Fixing a Power Button.... Can't believe 😂😂😂😂 Love your Videos . I know this Video is old but all ur Videos are great and in some Parts funny. Keep the good Work Up Sorin and thanks a Lot for Sharing with all of US 🙏👍
Hi im new to this? Where do i know which pins are the positive and negative so I can use a momentary switch to solder it to the pins? My laptop is the hp pavilion g7
Hi You will be able to get almost all types of buttons on aliexpress Or buy kits that contain lots of button types. Always useful. Thanks for the video
Amazing troubleshooting and repair. I learned a lot. I wonder if you could have been dealing with a tin whisker inside the switch. Instead of opening up the switch, maybe you could have applied some extra current to the switch to try to burn out the partial short.
Dear Sorin, again good video. I am learning a lot from you. Thank you so much. But i would like to ask why u didnt use Wd40 or a contact spray and press the button a hundred times:) could be easier i think. Best regards. From Turkey and Poland ...
This is very instructive video. Even that i know pull up/down resistors its nice to see how you find the right way to repair it. Btw. what probes are you using? (those banded ones from multimeter) I like those probes..
Hey Sorin, I don't know if you have changed your video settings on this one but the quality is very low compared to your others! All in all another great video!
Respect Sorin. You are my favourite electronic teacher. Every time I watch your videos, I give you a like before the video start. We have to be prepaired for 10-th of august, when the romanian people have to make a huge demonstration in Victoriei Square to get down that corrupt government fsn-kgb-psd and pay with that they deserve. A big revenge and after that, maybe a real revolution and elections anticipate!
It may be just a power button issue but the good diagnostic process is the key to solve these random issues as shown in the video, by the way i would've put the resistor and the cap back to their places they were just right there next to the board but you know it was a touch of dodgeness lol
@Sorin I am a big fan. Any chance you can show us how to mod a laptop to create an external power button. It should be neat without drilling big holes in the casing. The reason we need this is when you have your laptop connected to big monitors the only way to power it on is to open the lid to get to the button. This is really annoying when your laptop it buried under the monitors. Ideally we would have an external USB-A power switch. Can you show us how to do this?
Most of the time the micro switches can't acheave a reliable low resistance when pushed. I've seen devices get confused because of random resistances of dirty switches.
Since it's random, it could be the cable between the power button PCB and the MB. That would actually explain the "randomness" of the problem. In the video, you've found 0V on the other side of the cable, but never on the MB pin itself. The pin on the MB was 3.3V when you tested after finding the connection to the super IO, but then you assumed that the cable was perfect, which it may not be...
My laptop doesnt turn on and on the motherboard has 8-pin ribbon connector going to the separate board for power button and some LED indicators. I removed the cable from the motherboard and tested the ribbon slot on the motherboard and found voltage reading of 5v on the first pin (marked with arrow), and found 3.1v on the 6th and 7th pin. which part of those pin is the power button should be connected?
Ok Man, let´ see what you got today so far so good, nice one, thanks for always remember that for us, It is much better every time you used The Microscope! Thanks for doing that, ok, I got lost one part, how did you know was pin number 1 from the white connector? it´s always number one? or you did the measure and we didn´t see that? Thanks, Sorin, have a great day.
Sir pls tell me, i m always studying from you. i have a question about my laptop. when i put charging plug. my laptop is auto running without touching the power button. where can i check for it Sir. Pls tell me. Thanks you Sir...
Yeah, I'm sure I'm not the only one thinking 'Put them in a tray, or something'. Still, he does have a jar of odd screws - probably from when he clears off the worktop occasionally |-)
can you help me with a tablet it turns on but the customer locked it with a code and he forgot it how can I solve this issue a note to know that tablet have only one button the power button i really need any help with this issue
Hi mr. Sorin! I love ur videos, watch them all the time and I learn a lot. How can I get ur help like when you helped a subscriber? Is there anyway to contact you? Like an e-mail adress? Best regards, Christoffer
I need help. My laptop probably overheated and died. Now when I plug in the charger the brick dosent get hot and the laptop won’t turn on? Please help! Me and my friends are going to play games tonight!
Hi Sorin , Here is a teaser - I know answer - lets see how many get it right - At laptop boot see this message then laptop auto reboot repeatedly Message reads = PXE - E61: MEDIA TEST FAILURE ?
Sorin, you are the best electronic teacher in the world I've ever seen.
yes you're right is the best teacher in the world
goodest ever!

I appreciate you keeping the camera rolling while you disassemble and reassemble which is very informative.
Soren sir. I think what make you great is that you’re not afraid of trying and you don’t give up .Well done
Hi Sorin We watch with awe , twenty years of experience is impossible to teach in two years with such a varied array of faults, I love the honesty of your reasoning
your videos are a pleasure to watch, . please put screws in some old lids or something, we can't stop watching you.
am from Zanzibar Tanzania in Africa and I really enjoy your videos, thank you Mr Sorin
Also From Mtwara! Enjoying Free Education From Sorin
From Senegal
Botswana! Thanks for the great videos 😀
I am impressed. Never seen a Powerbutton from inside. Thank you Sorin.
I can see that you are from country - just like me - where we learned to repair everything and under any conditions. Just an old honest school. Most young electronics wouldn't do that. They'd rather wait for the delivery of the new component. Or it would declare the device irreparable.

Thank you Sorin ,You make it look so so easy . : - )
You're the best. ENG. TAIWO FROM NIGERIA
Sorin: i can remove this capacitor..... *emoves with tweezer*
me: hahaha
Soring: i can remove this resistor..... *removes with multimiter*
me: hahahahahaha
Sorin: i can remove this power button.....
me: remove it with your multimeter hahahahaha
iits funny how you consider those things as nothing for you, me i am extremely afraid of reming something with the tweezer from someone's computer, i am afraid of random things to happen so i end up doing two works instead of the original problem, it happened to me many times but now i take the lowest risk i can.

Hi Sorin, another amazing video as always. Keep it up big man 😊
not boring!!! very informative as always
Not boring you're good at what you do.
Un bonjour de France,merci pour votre travail très instructif 👌🙏
lucky for the power button...You are very so experience with small component...another lesson for me and thank you Sorin
Fixing a Power Button.... Can't believe 😂😂😂😂 Love your Videos . I know this Video is old but all ur Videos are great and in some Parts funny. Keep the good Work Up Sorin and thanks a Lot for Sharing with all of US 🙏👍
A nightmare resolved, well done Sorin!
Hi im new to this? Where do i know which pins are the positive and negative so I can use a momentary switch to solder it to the pins?

Cool video quite informative may God bless u Master sorin
Another video that I'm going to watch more than once
Hi
You will be able to get almost all types of buttons on aliexpress
Or buy kits that contain lots of button types. Always useful.
Thanks for the video
I wach you many video i love you. I love your teaching style and you are world's great teacher plz help me sir
I watched them all, always something to learn from him
Mee tooooo
Amazing troubleshooting and repair. I learned a lot. I wonder if you could have been dealing with a tin whisker inside the switch. Instead of opening up the switch, maybe you could have applied some extra current to the switch to try to burn out the partial short.
Intermittent faults suck!!! Excellent work.
Soring waiting for you to say "hey its friday" with a big smile
Very good resolution of the problem, with good concentration despite being surrounded by those beautiful work colleagues.
Another amazing job!
Dear Sorin, again good video. I am learning a lot from you. Thank you so much. But i would like to ask why u didnt use Wd40 or a contact spray and press the button a hundred times:) could be easier i think. Best regards. From Turkey and Poland ...
You just showed me what may be wrong with my wifes laptop, thanks a bunch! Also, did you forget to connect the wifi antenna? :O
wow amazing video thank you for sharing with us

unbeliveble :D :)
nice work
keep going
It may be just a power button issue but the good diagnostic process is the key to solve these random issues as shown in the video, by the way i would've put the resistor and the cap back to their places they were just right there next to the board but you know it was a touch of dodgeness lol
Tanx Mr sorin...

Simply amazing👍😍🤩
Most of the time the micro switches can't acheave a reliable low resistance when pushed.
I've seen devices get confused because of random resistances of dirty switches.
thats kind of normal, but this one had 2.2k without beeing pushed :)
just replace pull up resistor with 1k, yeah..we redesign the schematic
what the.....just found this amazing videos, thanks
Since it's random, it could be the cable between the power button PCB and the MB. That would actually explain the "randomness" of the problem. In the video, you've found 0V on the other side of the cable, but never on the MB pin itself. The pin on the MB was 3.3V when you tested after finding the connection to the super IO, but then you assumed that the cable was perfect, which it may not be...
I love you sorin from TZ
Dioxit spray would probably work fine?
Sorin why haven't you replace the capacitor and resistor you removed. Are the components used for switch debounce problems for the switch.
My laptop doesnt turn on and on the motherboard has 8-pin ribbon connector going to the separate board for power button and some LED indicators. I removed the cable from the motherboard and tested the ribbon slot on the motherboard and found voltage reading of 5v on the first pin (marked with arrow), and found 3.1v on the 6th and 7th pin. which part of those pin is the power button should be connected?
Sorin...how does a Reset Voltage Detector work?
Good sorin keep it up
i envy what you do, I got intested bought a lot of tools but nothing to fix lol im a software guy, maybe ill go doing projects
Nice...show how to work button in tablet :)
Try to fix imac power button, thats a hard job
proper pro job renewing the power button
Respect, domnu' SORIN
You are awesome. Random fault you find it. Thank you for the great work you are the best like like like like like five stars for you
Genius 👍👊👍👊👍👊👍👊
I'm level 4 and you're level9999999o
Thank you.
thank you very best !! very good ;)
Thank you
Wow.. Thank you so much🥰🥰🥰
I use an ice cube maker to store screws by areas, it make easy to find later
I like using monthly pill trays for holding small parts. The advantage is you can close the lid.
Thank you sorin sir,
Please let me know how to reset bios by shorting bios battery power if stucking in bios?
pull out the battery and with a metal tool (e.g. tweezers) short the battery contacts. Sorin showede this so many times, so where is the problem?
Ok Man, let´ see what you got today so far so good, nice one, thanks for always remember that for us, It is much better every time you used The Microscope! Thanks for doing that, ok, I got lost one part, how did you know was pin number 1 from the white connector? it´s always number one? or you did the measure and we didn´t see that? Thanks, Sorin, have a great day.
thank you sir
very good
With so detail...wow
Thank you teacher!
Superb
Sir pls tell me, i m always studying from you. i have a question about my laptop. when i put charging plug. my laptop is auto running without touching the power button. where can i check for it Sir. Pls tell me. Thanks you Sir...
You lose the screws because you leave them laying around all willy nilly.
Yeah, I'm sure I'm not the only one thinking 'Put them in a tray, or something'. Still, he does have a jar of odd screws - probably from when he clears off the worktop occasionally |-)

hello man
sometimes we can't hear good, the beeping is too quiet
Soak the button in IPA - that may clean it... :D
Hi Sorin , Here is a teaser - I know answer - lets see how many get it right - At laptop boot see this message then laptop auto reboot repeatedly
Message reads = PXE - E61: MEDIA TEST FAILURE ?
Needs another stick of ram - looks like another embedded CPU - hate those - good job
عمل رائع
But this phone is not turn on. It sonyc2305
Can you sujest any video.
Good day sir my system Samsung touch smart x2 no display and all the light keeps blinking
