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

Sorin...after all these years I still enjoy looking over your shoulder while you work!!!

[@chrisjustinmatias8783]

[@saarike]

Thanks again for sharing your troubleshooting prowess.

[@christianbanzi39]

Thanks for sharing this Sorin.

[@MrHimer12]

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.

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

[@stevelee838]

[@ardaa6017]

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.

[@m-itechfixsolution4337]

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!

[@jhl4744]

I have the same issue with my msi laptop too how did you solve it?

[@ysp6989]

So your problem was not the power button!

[@dakii.gajic_]

[@ZubairKhan-vs8fe]

A new video by my favourite guys. I want a T-shirt with words "what can be?"

[@kalmahnalyd4615]

You are a electronics god!!!!!!! Love your videos king!

[@gregorioalfonso46]

Got an idea... Thanks for the info sir.

[@MinhTran-tj4wq]

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.

[@libanioca6490]

Nice job 👌🏾

[@wallybe2946]

Awesome Thank-you for your time and effort very informative Liked and subscribed 👍

[@Babu-gw9ym]

and again very helpful, because you're doing a great job

[@zeusexmachina3991]

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.

[@Oak690]

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..

Ahhahaahaha that smile in the end 😂 as always, Master Sorin repairs are unique! 😁

[@knightwar3]

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

[@johnjohn-yp5tn]

good job sorin!!

[@recommendedforyou157]

sir I hope you can upload another videos about laptop goes on and off. thanks!

[@heryardiansyah7997]

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..

[@OverlandOne]

Well, I had a few guesses but the power button was not one of them. Nice troubleshooting.

[@Dr.muthanna]

[@arvintuando3929]

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.

[@mulatiechekol4513]

Thank you sorin.

[@swordperso]

Thank you so much, my oem keyboard was liquid damaged(power button on them). I replaced with china one like 2 week later suddenly shutdown and not started. I check any shorts on board and charging port to battery line everything was right. I'm was confused. But now i tested again without keyboard. It's started and not turned off. İt works :D

[@neilneilrebel]

Woooah same case with my laptop! Wondering what the culprit could be.

[@TopofTheHill3D]

this guy is a genius

[@ghislainriou9560]

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.

[@JayWalker2222]

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.

[@donald1056]

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

[@CarloTheImmortal]

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

[@bblod4896]

Power button acts as though a liquid leaked inside it.

[@MrRvdbeek]

Hello Sorin. Nice catch and fix. Is there something wrong with your light 💡 it’s flickering every second. Can you fix that too😬😂

[@rosch448]

greetings from germany domnu sorin 👍

[@daz41262010]

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 :)

[@Minds10110]

I just unplugged the power supply to the mother board, and cleaned the slot. There was some black dust there. Then it turned on like a charm.
