Thanks for this wonderful video tutorial. Btw, where do you get your schematic diagram?

Great information
But I have a question
What happens to 19v when pc is running on battery?

You've helped me a lot in understanding all the components in a laptop motherboard. May God bless you and reward you abundantly for your goodness and kindness. I always want to support this channel with little I have but I'm in Nigeria, We don't have a PayPal account to send money abroad.

Teacher i have a acer 5750 with a Brocken screen can i replace this model of the screen LP156WH2 with LP 156WH4

But how do I pay coz I don't have a bank account?

Thanks for your support
Please note that these 19 inductors you mentioned in old laptop boards.

Hi, very important, very useful... Excellent tutorial. thank you very much. best regards from Mar del Plata, Argentina.

Sir you are great indeed,the way you teach is more any college.. only that when am trying to test second channel and third channel am just finding 19 v,where am i missing so that i can find 3.3 vots and 5 vots ,but am using Dell Laptop motherboard

and am here too teacher like i said to u in the other channel arabic ur voice very similair for me 😁😁 so am big fan for u and learn so much good information for laptop repair so please don't stop 💪💪👌

Wow I'm impressed this guy is a good teacher

Thanks for the valuable information.

Sir,Thank you for your valuable information on voltages in Laptop Mother Board

This is excellent. Thank you bro.

Thank you for the video. Very informative video for newbie like me😄. But I want to know, where do you get the motherboard schematic ? or just by google motherboard model ?😅

And for the second thing, would it be possible if you make a video about which voltage is used for certain components. For example, 1.5v/1.35v is used for ram. And so the other. Because I just only know voltage for ram only. but not the other components😁😅

❤❤❤❤❤

how to know which parts of the motherboard is for 19v or 3.3v or 5v ? you can't tell that at glance , and sometimes all motherboards don't have their schematics online . Some websites ask you to create an account before , but once it's done they give you no access to the schematics if you don't pay

A nice video, keep inspiring, educate and share your skills, continue the good work with faith.

you are the best

That would have to be the best video I have ever seen. I have never seen anything explained so well before, THANK YOU!!!!!
