I've gotten a run of unfixable stuff like this lately. It really brings down the mood. That feeling you get with a successful repair is the best thing. :)
Do don't get yourself down brother.. use these times as encouragement to spur yourself on! You are capable, Now do the work!. If you love this stuff then just into it lad.. find out what can be done to fix these impossible ones.. if the customer gives up on it and you can get it cheap grab it by the though and pound it into submition.. It may cost a bit of money and certainly a bit of time.. but if you are deliberate and slow trying your best to actually fix the darn thing. then when you are done working or not you come out a winner. Carry on brother.. learn to be better than the master.. that is the goal of every student..
We all have these times if we do stuff. It is a pain, and that's why, I like to play a song "Always look at the bright side of life". That reminds me that we can't save them all ;).
That's about 0.6W of heat, usually no problem picking that up on a thermal camera. Unless the heat is being dissipated by a large component (like a CPU or something). Even then you can still confirm this - just cover the device with a blanket and wait 2 minutes before thermal imaging.
I love the Atten hot air station. Perhaps the only thing I would change is to make the hose slightly longer. I made a couple additions (DIY accessories) to mine a month or two ago. It's in my short videos on my channel if you want to see.
Just a thought -> if the real time clock in chipset is shorted, can the line be disconnected and some RTC emulator connected to it? If he problem is only with the shorted RTC, and the rest of the chip-set is dead. I know it's a long shot, but maybe worth trying.
Great content, as always! Could you help me with something unrelated: My OKX wallet holds some USDT, and I have the seed phrase. (alarm fetch churn bridge exercise tape speak race clerk couch crater letter). How should I go about transferring them to Binance?
Hello Sorin from Sydney. Dynabook laptop. Questions generated. 1. N channel MOSFET (8036 Ou) at PCB point P05 D59 19.4v -18.7v remove and replace? Could laptop work without that MOSFET? 2. Resistor= 169 ohms next to the reset button. Remove and replace? Could laptop work without that resistor? Thankyou 🌏😎
1. No. Well, yes, but the other MOS will blow up very quick. The gates are together. You can't expect the remaining one to pick up the slack, which is why Sorin replaced it. 2. Yes, but why? Engineer didn't put it there for fun.

@@tinkmarshino thanks 🙏 I appreciate the encouragement!

sorin we need long videos 😊😊
Well done boss.. I appreciate you teaching and training.. Carry on !!
14:30 say hello to my little friend 😢
All the best electronic technicians say "I'm still learning"
For the first time in this channel i see shorted MOSFET with 160ohm resistance between gate and source. Usually the short is zero ohms
How's that atten? Thinking about aixun H314, either that or atten, definately not quick.

We need long repaire movie👍
No
Sorin, the next logical step is to start fixing the chipsets 🤣
Just a thought -> if the real time clock in chipset is shorted, can the line be disconnected and some RTC emulator connected to it?

Nice repair Sorin and i whant to ask you way you use the termal pad wher is the turbo jet fan?
He lost the fan in his house (he said it on a previous video) 🤣
I think his well calibrated dog take it for a ride😂
im disappointed i didnt hear WE HAVE PICTURE !!!
so this is the same as the last zenbook laptop? how about removing main battery and cmos battery? can it turn on?
what resistance value of this dead chipset Sorin? thanks
IMHO, when you give a voltage between Gate to Source it's better not exceed 6 V
Thanksssss
hello mr eng
why when you plug the charger and connect the battery it goes blue light indicator then turns to orange
A1!*
What voltage should be at the gate?
Higher than 19V - usually 25V IIRC.

Nice! 😎
I know it's not crucial, but you might wanna correct the title to "Always" - some ppl might not like it ;)
Thank you!
Just press the rest button it was next to you
Manufacturers message to the people: If your chipset is dead buy a new motherboard... Problem fixed. Now in 2030 it will be buy a new laptop.
oh come on Sorin !! its " We have nice laptop to repair!" not "We have nice laptop toshiba..." whats wrong with you ? :D:D
Such poor design. Rather, intelligent design, for manufacturer to force customer to buy new product. MOSFET fails, takes out the chipset...
⚠ 9:21 _"..we know for sure 100% the mosfet is shorted"_ what a joke 🤨
😅 it happens
Sorin, please can you cut the "Hey" from the outro? (not the whole thing, just the "Hey". It is like shouting on kids doing mischief. Thank you.
sorin we need long videos 😊😊
