I have watched many such tutorials over the years but sadly most skip past the basic circuitry and functions of the various components whereas you explain without missing these obviously crucial steps !!
I just wanted to take a moment to express my sincere gratitude for all the hard work and effort you've put into it. Your dedication and commitment have not gone unnoticed, and I truly appreciate everything you've done.
I asked basically the same question. Are they all on by default, but I would guess that would be by design. I guess the best next thing would be to inject the signal to the gate see if the MOSFET switches on.
@@aewcontrol2984 i don't think that's the case, because how else could 3.3 v be present to power on the laptop, i think its always on and if something happens the controller turns it off to protect the laptop..
@@Bias_Prineus I do not know enough to make that judgement. I do understand that MOSFETs are commonly used as voltage regulator, switches, etc. SO in this case do you think they act as a circuit breaker that it's always on and shuts off under certain conditions?
@@aewcontrol2984 yes there's no other way, because that's the main power rail, and the super io controller check all the rails for proper operation, and if it detects a short to ground or an abnormal rise in current somewhere, it cuts down the power to prevent damage on the board through the gate PIN of the first MOSFET, the second MOSFET i believe is to maintain the voltage stable, that's my theory , i don't know if I am right..

Wow, thank you! You are very welcome Bro
big help ty ..... close up is perfect... u explain really good................
Thank you
Most interesting tutorisls ⭐
Appreciate the support!
Awesome video .What part of the board is the black pin of the multimeter connected to ?
The Ground
he is a great educator. Thank you!
You are welcome!
thank you for sharing your experience!
My pleasure!
Hi, the charge ic must command the MOSFETs on, or they are on by default thanks
Yes the charge ic must command the MOSFETs

Good man sharing information,thanks a lot for your informations and hard work..
My pleasure
His good!...
very interesting thank you
Glad you think so!
thank you !
1:07 - I don’t know what has changed; but, the “background” music is distracting in this video.
What if the IC is not sending the signal to the gate?
In that case the IC could be faile if all inputs are present
What's the point in checking the connected pins of MOSFETs one by one for three minutes
In order to understand the Basics (For beginners)
