Natural selection of tools - You've made my day, first I was laughting, then i realize that on my desk is exactly the same situation when I repairing electronics, tools used very very rare lands on the floor when the desk ends ;) I like playing Your videos when im repairing things, even if cant watch, just to hear what You have to say Started from the oldest and watching every day for few hours Few tips from Your videos was very useful, keep it up, good work!

You have an incredibly challenging work environment, Sorin! The mic you normally use blocks out the background noise for us. But this time, we could hear what you face daily. You have to deal with so much noise and distraction every day. And you have so little space to work on the things. All this, and you're still able to work so efficiently and teach us along the way. Wow! You are a really talented and patient teacher. I'm sure the mic will be sorted in future vids. Thanks again for all your efforts!

Hi SORIN!!! Thanks for your time, your effort and above all your explantion, for now it's 100% accurate -at least with my level- but for your way of repairing I don't mind since you can fix the issue so don't waste time trying to do (default repairing) this is obvious, keep shining and as I already said you are inspiring and I became addicted to your channel too, have a nice day!!!!

Thanks a lot, after removing the mosfet would it work if you only jump it with a wire like you did in many of your videos? if not way?, thanks

@zx8401ztv 6 жыл бұрын

Hey we all have those days of forgetting stuff, you are not the only one :-). You still have a bit of a cold, you are not 100% yet. You may want to discribe the power channeling mosfets as "Gates", open or closed gates, for people that dont understand. Usually if the mosfet has a P junction, then the gate voltage is lower than the drain to switch on, and a N junction gate is higher than the drain, as far as i can remember, but mosfets are something i didnt learn much about lol. i could be wrong LOL

@electronicsrepairschool 6 жыл бұрын

no, your right

@lesleymunro4964 6 жыл бұрын

Actually It's the difference beween the gate and source (Vgs) which turns on a MOSFET. N channel, the voltage is positive beween the gate and source, P channel it is negative. This doesn't mean you need a negative voltage on the gate, only negative in relation to the source. In that circuit, the source is connected to 19V, the drain is the output to the rest of the laptop, and the gate would get pulled low to turn it on. I found a quick tutorial here which might make sense of it. www.baldengineer.com/p-channel-mosfet-tutorial-with-only-positive-voltages.html

Some charging ports can become damaged through constant wear. I have found on some DC/IN connectors that the central pin & the side rails can sometimes become loose or bent enough to not sustain a proper connection with the adapter end.

Sorin, cei doi mosfeti sunt de regula de tip P chanel. unul e ous invers fata de celalalt. Daca chiar ai nevoie, cauta schematics pt hp 4510s si poti observa. Sunt si modele cu unul P si unul N, chiar si modele cu un singur mosfet P ch. Sau uita-te ce scrie pe spatele mosfetilor si vezi ca sunt la fel. Cauta apoi schematics pt ei pe net.
