It was the best explanation which i can hear in 10 minutes. Explanation, videoand voice recording quality was great 👌

[@electronicsrepairbasics_erb]

Thank you so much! I'm thrilled to hear you enjoyed the explanation and the quality of the video and audio. Your feedback is really appreciated!

[@kenancakir9166]

Congratulations. I've never seen such a beautiful explanation before. Thanks for sharing your information. I'm your new subscriber.

[@electronicsrepairbasics_erb]

Thanks and welcome. Share this tutorial with interested people like you so they can benefit.

[@ernieschatz3783]

I have seen zener diodes check good with a multimeter, but fail when you apply enough inverse voltage to put them into regulation. Same principle with a MOSFET...no continuity with a multimeter doesn't mean it will switch on when you apply the correct voltage to the gate...so I would't say no continuity while static doesn't mean it's "automatically good"

[@CRAZY_VIDS07]

Great video but after 10min into it going crazy with you saying OK every 2sec.😅😅😅and still have 1hr and half to go..😅😅😅😅😅

[@EmmanuelKalinde]

Thank you for a wonderful tutorial Sir. But sir I hav a dell latitude laptop and It popped a notification that my AC adapter is supplying less power hence will run its operations very slow. Which really happened. I checked voltage on my adapter and PC port it was oky 19.5v. what could be the problem Sir?

[@electronicsrepairbasics_erb]

Hi Bro, I can assist you in the Patreon Page, you are very welcome

[@ernieschatz3783]

You found there was no 3.3vdc on the first board. Why not show how to isolate the problem and fix it?

[@electronicsrepairbasics_erb]

Stay tuned, more to come

My acer swift 3 laptop died. No power and is out of warranty. Only 2 years old. I rang Acer and it will cost me 210 AUD to replace the motherboard which is cheap . Motherboards on Aliexpress and eBay cost 400 plus.

Please I have problem VIVO laptop switch that gives power indication when I press the on button. The problem was caused when powering the laptop with small gasoline generator

[@Kane2009]

Great tutorial as usual. One question please, from what I understand that it is normal to find components near the CPU giving positive continuity that goes away when we remove the CPU? Or this means that the CPU is faulty? Thanks.

[@electronicsrepairbasics_erb]

Correct, but the CPU is not faulty, it's inside resistance is low by default.

[@ernieschatz3783]

The MOSFET near the power jack had current flowing from the power jack to its drain then out of its source which is connected to the next MOSFET drain. Does that mean they are P-type MOSFETS?

[@electronicsrepairbasics_erb]

Right

Very clear 10q brother but how can fix all problem that we gets
