    but in this video it is like from input 19v goes to on side of double mosfets and from driver creating 5v alw and from battery input goes another double mosfets and goes out from driver as 3v alw ... it means like 3.3v alw cant be created without battery ??

      No bro, the 3VALW and 5VALW circuit is independent of the battery circuit

      I’m having same issue, the vin of the 3v/5v IC is linked to the battery voltage. 19.5v is present but the bat+ is missing hence the laptop is not turning on. Have changed BQ IC but same issue, will try to change the double mosfet linked to the BQ bat+ side

    Again..no real practicals. He keeps telling us they will come..but he is not telling us the truth. All he needs to say is that practical are only for paid for videos. That is it! No problems..but he just teases us with part 1 then never a part 2. It keeps on happening.

      No, Brother, don't say that. I do my best to satisfy you. If you pay attention I did this video even if I'm sick. Tomorrow part two.
