Very good explanation. I was logically expecting the mosfet to be turned on by something that was powered directly by the VIN from the DC jack but ChatGPT was trying to convince me that the BQ chip was powered by the B+ voltage which makes no sense.
Hi. Very very nice explanation. I got a good full explanayion. I know how the charging circuit work. But it was 50 persent. I was searching a long time,for a explanation like this. Its wonderful. Thsnk you master
yung yung isang klase ng charging architecture yung nvdc yung 20v or 5v i boost ng 2 unang mosfet sa coil then yung next 2 mosfet naman eh regulate papuntang battery na agad

Very comprehensive, accurate, and easy to understand! Waiting for the PWM explaination video 🤣👌🏻💯❤️
malking tulong to..mas naintindihan ko na ngayon..salamat sir..
Thanks for the clear explanation! I'd be interested in seeing more videos about laptop repair. 😀
@@kavishnangmg thanks for the support brother♥️
Nice explaining man , you did a nice job better then i ever could i will use your clip a lot when i help someone .😊😉👍
Saludos desde Perú 🇵🇪, una consulta y porqué no consideraste el pin 23 y 26 que van al los mosfet
Thank you for the informative video. Hope to see more of this video from you! More power to your channel

Thank you for the support,.. if i remember it correctly you are our rizsha from the SIERA server right? 🙂
@@ARFIXIT2022yes yes. Thanks all of your support. I do repairs by the help of masters like u and others in discord
Great lesson thank you very much.
Great video.Thanks a million.Lets continue learning together
gawa po kayo ng kaparehong topic this time sa desktop motherboard naman sana.
muchas gracias !!! excelente explicacion !!

you're the best bro
Just Amazing!
@@TEMPODEAPRENDERJairoGSilva thank you❤️
Thank you brother
Thanks teacher
Next video
Grabe solid ka talaga sir fred magturo ❤️❤️
I have the a machine, with such charging ic, but laptop not charging, phase has 0.12 volts, what could be the failure
ACOK is not present, what is the reason? and what is the solution?

Great video.
Nice video thanks
nice bro
🎉
Hi, the discord link is not working for me
may follow up question ako sir fred bakit on some board there are 4 mosfet sa highside at lowside? ganda sana may part 6 yung sa PWM
yung yung isang klase ng charging architecture yung nvdc yung 20v or 5v i boost ng 2 unang mosfet sa coil then yung next 2 mosfet naman eh regulate papuntang battery na agad
Alfred, pre musta na? nagrerepair ka na rin pala ng laptop chip level?
ayus lang ako.. yeah,.. Hobby lang and sharing knowledge pre... teka, sino pala ito? hehehehe..
si Jun pre. kasama mo dati sa ksa :)
@@JhonyVerganio ahhww..ikaw pala yan pre..hahaha..add kita sa fb pre..matagal na kita hinahanap..buti nahanap moko..hahaha
Pano boss i bypass ung ADid?
Ta
or u just read datasheet to that charging ic and have all this info.
