How a simple power button backlight repair can be impossible to be fixed (in a normal way)

[@MilekaRobot]

Nobody cannot perform dodgy repair without great knowledge of electronics, so when you do something like that we learn more than usual :) Great video!

[@davidharvey4059]

For a man who said the problem can't be fixed you did a damn good job of fixing it.

[@stevenyuliagenadt9895]

Sorin just like to say this, I love your KZbin watch it all the time, I was born in Romania in Brasov long time ago and you are a typical Romanian funny character, unfortunately my father, mother and grandparents that brought me to Australia as a kid, have all passed on but you remind me so much of them and the Romanian sense of humor and great Romanian character and I love it. Keep the great and good work up and greetings from Sydney Australia.👍👍👍

@ Zoran: When I finished reading your comment, a cold sweat ran down my back because at first I thought it would be a tower of babel (language or tongue confusion) but I must admit that it sounds fabulous even though I'm sure it shouldn't be admitted (lol).

That satisfaction on his face after fixing the problem is priceless

[@LotharG-f4c]

That's so strange. I don't think anyone considered that. Well, this channel isn't called "electronic repair shool" for nothing, hehe. Sorin would be the perfect trade school teacher. That's how easy it is to solve a problem that used to make your head spin. I'm celebrating. Yes, I too voiced my theory about power management and I'm all the more amazed at the end result. Thanks Sorin for the clarification. You just never stop learning...😉

[@hariomengineering845]

i'm not from a technical field but i am trying to learn something from you coz you have a great knowledge. Thanks

[@Oak690]

I repaired a HP laptop once that had a LED problem - the problem was the white LED on the DC jack would illuminate when the charger was unplugged. I found an open trace on the motherboard, specifically a via was open which caused the LED to stay on if the charger was unplugged. I had to run a small wire to repair the trace. It took a very long time to figure out. Thanks for sharing as always Sorin. I really enjoy ALL of your videos!

[@Radek__]

3:02 "gate in(on) the air" much more often I've hear that not connected (or unconnected) pin(pad), is called: "floating", or "lifted up" or "open"

[@prgoncalves]

Hi Sorin, the problem could be a burned pull-up resistor, you should be able to fix that inserting a pull-up resistor at the gate of that mosfet

[@hameddesign70]

I will send my future failure laptop to you not to repair it but for demonstration , gosh i love your videos ...

[@heno_3098]

The pull-up resistor from 3.3V is missing or broken on the motherboard, but according to the correct design of the circuit, this resistor should be on the button board so that the same failure does not occur after partial disconnection of the flex cable.

[@lucymc0191]

Put the laptop in a box, then like Schrodinger's cat, is the light still on or not 🤣🤣🤣

[@YoutubeSupportServices]

Made it to 9:26 thus far, my first guess on the other video is still "holding water" 🤗... Personally, I'd take that small "switch"-board out, drench it in flux, and REEEEEEflow the entire board. Then when it works, tell everyone; "When the timing-chain jumped a tooth it sent metal-shavings downstream to the muffler-bearing and shorted out the blinker-pump!

I've seen many laptops with burned input circuits where the gate was floating and could be turned on simply by touching the gate since your body is capacitively coupled

[@DanielsGameVault]

You might want to read the comments from the original video again - I mentioned it's caused by a floating gate ("gate up in the air" like you call it) :D

[@electronicsrepairschool]

Sorry, i missed your comment there. True! GG

[@repairtech9320]

@@electronicsrepairschool Hello Sorin. If you feel like it... Could you explain what's happening before and after the repair with a little schematic? Thank you

[@stuartmcconnachie]

“Gate in the air”, or more usually in English “Floating gate”. 🙂

[@Drottninggatan2017]

Floating means liquid damage.

[@Danny4Driver]

@@Drottninggatan2017 no, it is not. It is described very well in electronics. When you are referring as "floating pin", this is the meaning.

[@christopherj3367]

is it a finger print scanner too? or just a push button for on and off?

Sorin you could just try swapping/flip one end of the ribbon cable. Fixed same problem for me. Someone connected the ribbon cable wrong. 😂

Some non-English mp3 songs or their instrumental cause backlight problem, and Asus battery memory effect. To repair, first you have to delete the songs, then pull out the vga cable from the motherboard , then plug it back.

[@yeahright9014]

From stackechange: "By the way, since a PMOS has very high input impedance, it can turn on accidentally. If you ground the PMOS' gate, it'll short the body diode when the input is applied properly. This is the proper way of implementing a reverse polarity protection with a PMOS."

[@sipansibabdreddknot5179]

Can you replace the pmos that having that problem floating gate? Or some resistor value is not good anymore?

[@randyr.parker2698]

I think a schematic would be in order here for what you're saying. It would take a LOT of time trying to locate one particular resistor that may be causing this problem. Who's to say Sorin didn't just bypass the same trace supplying both LED's when he attached his wire. The same trace could have split somewhere on the board in two different directions to supply each LED and he bypassed the bad trace. Hard to know without a schematic.

[@imalshanaka3991]

Sorin can you explane laptop ics main signals and voltages ? Eg - Ac ok Ac Det

[@JustMe-in5jn]

I've seen desktops in the background. You don't do the repairs on them?

[@icommandoi145]

Interesting so it wasn't a fault with the laptop LID not being detected that it's closed or open. My Dell lights up when the lid is open and turns lights off when the lid is closed, which is why I was thinking from that side of logic. On the connector pin 1 has 3.3V and pin 2 had 0V, so why not solder or bridge pin 1 and pin 2 on the connector?

[@westsenkovec]

Maybe we should try to flash the BIOS first.

[@carlosgarciaoropeza5480]

@W. Senkovec: Please, West, the Master is beginning a "detox." from the programmer and you mention it to him again. If he "relapses", you and I will be "guilty" (lol). All the best.

[@domenico2373]

Ciao capo only my opinion why not gate in the air? why turn on off by temperature change. oxid can bring "voltage in the midde" clean the robbon connector propely amd resold.

And why did you connect the front led light power to the mofset;s gate instead of the front led's mofset's gate to the keyboard's led's mofset gate?

[@fraizfester8713]

The LED indicates, that Sorin is detected and turns off :)))

[@ch2o2]

You haven't "solved the riddle", you've just overruled the actual function of the LED and for our Sunday morning breakfast you gave us again big evidence of never-ending dodgyness. What surprises me is that you didn't consider drilling a separate hole in the laptop case to add an extra switch to turn the LED on and off ,D (no offense, Sorin, I'm just kidding - you're doing a great job - I love your informative and funny videos )

[@vkp111]

You whats funny? I had a PS4 where the power button didn't work. I went to heat it up and it worked. I know I shouldn't have had it plugged in but when it cooled it stopped working. I figured heating a capacitor sometimes does this and I was right lol.

[@radminas2739]

I would't like my computer to be fixed this way. It is a dodgy way, the real reason wasn't found. And it is not true that anybody gave you good suggestion under the previous video. There were several comments, where people wrote like "100% it is a hardware fault", that the fault can be related missing/damaged pull up/down resistor or poorly filtered (faulty capacitor) power supply.
