I received laptop from my client with same problem. I thought I had no solution until I saw this video. AMAZING?? The power button is soldered on the motherboard. I tested it and found it well. I remembered to do as I do with the garage remotes controls. I washed the plate around the button with the KONTAK PCC spay and luckily it worked. Now it works perfectly!!
In my experience with repairs, I know that, with apparent large anomalies, it may only need a small repair.
Tanks for this channel and for the inspiration given. Be happy
For the power button the other end of faults can happen too: Corrosion happened inside and the button doesn't register anymore. This can happen over time especially on power button as every time the 3.3V touches the ground, there's a tiny spark inside the power button and it oxidises just like that. Also fixed with alcohol, petrol or contact cleaner.
For me I like to spray contact cleaner inside and mash the button 2 dozen times and see if it works before I take the hassle and disassemble the button

Sorin...after all these years I still enjoy looking over your shoulder while you work!!!
Powerful video Sorin, this helped me alot cz l have been worried over this kind of issue but wow SORIN bring a quick solution for others like this one
Clever way of cleaning it in case you don't have a replacement. Usually if possible I change those buttons because they're not expensive and if you are having atypical one you can extract one without damaging from the donor. In case of power buttons I am the type that praises changing them instead of trying to fix them. Reason is - depending on the user but most of the cases of failed switches I had where buttons with diaphragm that either lost it's sping force or was almost completely flattened out so cleaning it would make small diffrence there. I can give you fan fact here - Dell, lenovo, asus. In some models you can encounter surface mounted switches without casing, only thin kapton alike cover glued on 4 sides to the plastic. Well I had one Y540 Legion. The kapton part fell off and diaphragm went flying on the MB which caused shorts and extensive damage. Sometimes easy things are obvious, sometimes they're tricky and sometimes they bring pain and suffering but... You never know.
Thanks you sir I am from India a small computer repair man you have a great knowledge and way of teaching is awesome sir I am your big fan ... 🎉
Hi Sorin. Your videos and knowledge sharing are very precious as usual. Yesterday, I exactly had the same issue with my MSI gaming laptop. When I press the power button, power light comes on, and then it goes off. Nothing on the screen. I started to sweat while pressing the power button again and again. Last time, I pressed the power button for about 30 seconds for resetting bios according to MSI instruction. Thank god! The power light blinked twice and it came back to life again. I will never have such a relief moment in my life again. What a bit of luck? I always watching every video that you post and they contribute a lot of knowledge and logics about IT products. Thanks for your warm explanation!
I have the same issue with my msi laptop too how did you solve it?
So your problem was not the power button!
"Ok let's press it".. third hand appears with tweezers.. ✋ ✋ ✋ 😀
I knew it was the power button, it happened to my surface pro 4, its tricky really. Its your old video about the power button issue that made me realize i have the same issue. Thanks for your videos Maestro.
Hey Sorin, thanks for showing another problem area. I'd never think that a button would short the whole computer. This was very helpful. Have a nice day kind sir.
Hey Sorin... Keep safe always... Thanks for the upload videos . God Bless You & your Family...
Excellent repair and cold worthy hint! Thanks a lot.
Thanks again for sharing your troubleshooting prowess.
You are brilliant Sorin
Thank you so much
I always wait for your videos
Thank you Sir. You're a good teacher. Good bless you.
good to know all possible causes for future reference! Thanks Sorin ☺️🙏
What a knowledgeable issue 😊
Nice Job Old Man 👌
Thanks for sharing this Sorin.
I thought it would be corrupted bios not the power button
Sorin is a genius
Thank you so much, I got the same problem with Dell Inspiron 3169.
Your video helped me 👍
Hello.. does your laptop suddenly turning off if you try to open it?
I was talking back and you answered! Thanks for this lesion, helpfully and with the right humor.
Ma bucur nespus cand vad inca un clip de la tine. Am invatat mult de la tine.
This work is so precise!
Love your channel! Love your look on electronics dodgy or not from sweden
Greeting from Serbia Sorin!!
Thanks for sharing this Sorin! I repaired a laptop with a similar failure once. It had liquid damage under the power button ribbon cable and some damage on the connector (power button board side). Cleaning the connector and replacing the ribbon cable solved the issue.
With faults like this its always best to eliminate what you can buy unplugging things - LCD, USB boards, hard drive, etc..

Tricky indeed, i had this issue on my old dvd drive the tactile push buttons switch fail because of bad contact i prefer to scratch that tiny piece carefully without damaging its shape and in the inside too then clean everything with alcohol and avoid using too much flux when soldering them it goes inside and it sticks there some are easily fixable and some not
Very clear explanation..thanks bro!❤❤❤
I love watching how you diagnose laptop...i want to learn more from you, but i have a question, i usually see you touching the board, dont you get shocked? Cause even though my laptop is powered off witg the avr, i still get shocked.
Nice work! I have this same problem, Acer Aspire 5755, but not sure if its the power button like in this video i will use same method to start it and see if it boots without power button.
Awesome Thank-you for your time and effort very informative Liked and subscribed 👍
Got a Toshiba lappy doing this...blinks 3 times and powers off too. Nothing seems short on the board. I'ma try this with the crazy thing!
Great job teaching !
Another great video, keep up the good work.
The real sorin magic is: the fault finding ! Great !
Absolutely fantastic video can I ask what microscope you use
Thank you so much Sorin. You are my best teacher
Nice one of your best . I had same issue where I almost replaced motherboard
You are trully the best idol Sorin! You're not human. You are Cyborg. LOL. Thank you. No one on this planet will ever share something like that. Youre the best teacher this world has to offer.
Very very interesting ! you're the best my friend ! Bravo...
finally i know what day is, i already forgot :) great job!
Nice job... Great learning outcome.
Impressive. That was a very good find.
Good day Sorin what is the brand name and model of the multimeter that you use please? looking forward to your reply. Thank you again for a good video.
Thanks for the info about short circuiting power button pins not going to do harm to laptop. life saver. mine sparked but didn't work first time bc lid was closed i guess. do not forget to open lid not just look at the fans.
You are a electronics god!!!!!!! Love your videos king!
My sister just gave me a similar Toshiba laptop and it behave exactly the same. She said she just replaced the cmos battery. I was hoping it was the power button like this case but it end up to be her laptop battery that is causing the surge. Boot up and run fine when the battery is removed and run on AC power.
Excellent approach!!!!..
Thanks for enlightenment,i've been scratching my head all the time
haha . this issue was my nightmare. I have fix many laptops and few of them that i didn't fix had this issue. Probably that was the reason. Thank you so much.
Great, step by step diagnostics
i remember you fixed maxbook button long time ago, truly and electronic repair channel
I would have spent a nice 1 week figuring out the problem if it was not your video Sorin, always educational🔥
Thanks for this man. I was ready to give up honestly 😭😭.
Got an idea... Thanks for the info sir.
hey Sorin, I have an HP Laptop that seems to just shut off when you move it, and has problems turning on, have you found anything similar? I believe it happens in both battery and charger and the problems extend even if the battery is not installed
Nice video. What about if it is most times continueously retrıies and comes on and off. But on battary no problem, normal start. Thanks for your reply.
OMGGG It Save My Laptop!!!!! I thought it's a garbage na! Thank you so much, Merry Christmas and Happy New Year, saluttee
Ahhahaahaha that smile in the end 😂 as always, Master Sorin repairs are unique! 😁
Amazing. Teaching by doing.hands down. God bless.
Dear thanks alot so, the second mosfet the input has 19v and output is 17v and the current resistor/sensor has 17v is that right?
No idea but my laptop just turns on when I plug the charger in it, i guess it is something to do with that lid senser.
And or possible short circuit with the button components.
thank you very much sir.. this button makes me ill.. maybe the user had pushed very hard so the thin plastic ribbon broken.. you clear me and save my time.. best lesson..
Well, I had a few guesses but the power button was not one of them. Nice troubleshooting.
whatt if the power button is included with the keyboard?? how to check that? does it have to open the whole keyboard?
How do you test the voltage power supply. Its not clear on the video i cannot see
Thank for good sharing. Could you sharing about all IC functions in motherboard. Thank in advance
sir I hope you can upload another videos about laptop goes on and off. thanks!
and again very helpful, because you're doing a great job
Nice job 👌🏾
At 6:55 what senser is he talking about? Lead senser? I was having the problem being discussed here and removing the power button ribbon cable made my laptop able to turn on so I'm thinking replacing that senser and power button could fix that issue. So someone could please tell me what senser is that.
And my power button is on my mother board... Sooo why does removing a long black ribbon cable which is connected o the mother board an then goes under it, turn my laptop on and stay on?
You sir, are a genius!
Thanks Sorin. I like your videos very much. Especially your style. Actually I got interest in repairing laptops after watching your videos. I have a motherboard that develops bios, ram and core voltages after pressing the power button but then goes off and the power supplies. Main power rail remains present at the input. It tries to turn on two three times and then remains off. I have tried to turn on by shorting the pins to bypass the power button but no success. Any idea about the fault? Which area to check further please. Suggestions from the forum members are also welcome.
What happend with Samsung A70 which no picture? Was problem cable or not?
If ram, fan, power cable all replaced but it still does this fault, what could it possibly be - so lonovo g580 2689 when I turned it on, it constantly beeps, the fan would be on, it turns on but not fully, it does not show any logo, when press the key to open the bios menu pop-ups it shows the menu, the mouse and keyboard works but when I click on the bios option in the menu any option, nothing happens, all that happens is the the bios menu pop-up disappears.
When I say the bios menu pop-ups I mean the menu (startup menu) that has other options like - system information, system diagnostic,boot device option,bio setup, system recovery, network boot etc.
When I click on any of them option nothing happens other than that (startup menu) pop-up disappears
What can I do if my power button in on the motherboard like a hp250 g8
Opps i think i have the same issue with my laptop, but the botton is so small, is it possible to fix this myself in home, what tools do i need to make it fix?
Thank you for this video sir very helpful
Gob job, Master, thank you!!!
A new video by my favourite guys.
I want a T-shirt with words
"what can be?"
You are the best, thank you
Woooah same case with my laptop! Wondering what the culprit could be.
Hi sorin , thank you from India 🎉 I had the issue with the ribbon cable that connects to the power button pcb . Thank you thank you
Hello, Sorin I have Toshiba Satellite Model LP55, sometime i switch on power and laptop working for minute then it comes off, sometime it working for one hour or two hours and seems working properly , and and comes off again, sometime it take longer and working, i did clean cooling fan already, butt still the same . it happen specially when i start laptop . so what the problem you think ?
hey sorin thanks for posting but i would've loved to have seen the video where you diagnosed this fault how and why also what you did to do the diagnose it :)
good job sorin!!
Sorineeee asta e cea mai dodgy!!!! :))))
The doggiest one!!! This one beats all other ones!! 😂
The lesson is ver good!!! Keep up good work!!!
GOOD JOB.FROM THE TOP MAN.
Sir i would like to ask one question Could you clarify please if u connect to the charging port 19v and additionally u come with power supply what is that voltage u given additional to the capacitor on the power rail
I think i have a different issue i tested the continuity on the buttons, they seem ok, but I think my issue is the power button port for the cable, because I also tested the continuity for the cable out of the 2 ports.
All 4 pins or paths work, so it seems like that or some other component on the button bored, I say button bored because the lonovo g580 2689, has a separate bored that has 2 buttons on it , the power button, also another button, I found out opens the bios menu.
When I say separate bored I mean not connected to the motherboard.
I am not sure what happened as the buttons worked or atleast the bios menu button worked, all I remember is there was a spark when I pressed the power button, I think it is because the cable from that bored to the mother bored or ane the port/s are very loose so basically it shorted.
Because I think after it shorted the buttons stopped working.
Multam fain pt info :)
Sorin, would you please help me to solve my laptop's problem when it is loading windows suddenly shut down. but during windows installation, no problem happens.

Cleaning the inside of the start up button is all it needed and it didn't look dirty - just dust - wow - replace it for 10 cents +- or fix it by cleaning the inside - wow
