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..

@@tinkmarshino thanks 🙏 I appreciate the encouragement!

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 ;).

Well done boss.. I appreciate you teaching and training.. Carry on !!

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.

Thank you Sorin for everything. Every day I learn from your videos and I don't go a day without studying your repairs. I work with electronics repair, more precisely with laptops and desktops, but I always learn a lot from your channel I live in Brazil in the city of Santos, but my soul is linked to the United Kingdom and other places in the world. Thank you for everything and congratulations on your commitment and dedication to everyone

The general rule of 25V on the gates ,is it for all PC main rails (non Mac) or for specific boards and brands like Toshiba

@codernov Ай бұрын

How's that atten? Thinking about aixun H314, either that or atten, definately not quick.

@JustInspiredKent Ай бұрын

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.

@krasimirmitev2573 Ай бұрын

For the first time in this channel i see shorted MOSFET with 160ohm resistance between gate and source. Usually the short is zero ohms

Which USB Screwdriver do you use ? It seems to be good !!

@gabest4 Ай бұрын

PQ5/D59 can be a mosfet or diode? Looks like they left both option open.

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) 🤣

@miroslavstevic2036 Ай бұрын

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.

@ragilsp2164 Ай бұрын

what resistance value of this dead chipset Sorin? thanks

@viniciusvbf22 Ай бұрын

Sorin, the next logical step is to start fixing the chipsets 🤣

@james.8985 Ай бұрын

What voltage should be at the gate?

@viniciusvbf22 Ай бұрын

Higher than 19V - usually 25V IIRC.

@Rodox2k10 Ай бұрын

It depends on the type of Mosfet you have. For N-type, IIRC you should get 6V when measuring the gate against the source. When you're measuring the gate against the ground of the board, you should get 25V.

so this is the same as the last zenbook laptop? how about removing main battery and cmos battery? can it turn on?

@sherifsamy6129 Ай бұрын

hello mr eng why when you plug the charger and connect the battery it goes blue light indicator then turns to orange

@johnfitzpatrick2469 Ай бұрын

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 🌏😎

@yeahright9014 Ай бұрын

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.

@mahmoudgh1893 Ай бұрын

Can anyone explain to me how the voltage on the psu dropped from 19v to 7v when he pushed current into the battery?

@piccoloijo Ай бұрын

IMHO, when you give a voltage between Gate to Source it's better not exceed 6 V

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.

@FuchsHorst Ай бұрын

Why is this unit unfixable? The shorted mosfet should not have harmed the CPU or rest of the board, no?

I know it's not crucial, but you might wanna correct the title to "Always" - some ppl might not like it ;)
