    Prowise 11.6" Chromebook battery not charging

    Hello all,

    Just got in this Prowise 11.6 inch Touch Pro Line Chromebook.

    Problem is that the battery is not charging. Adapter is okay (19 V) and the LED next to the dc-jack is also lit.

    Tracing back from the battery connector i found CR8N1 defective.

    Does anybody have a schematic for a WIZPIG Ver 4.0 mainboard ?
    Or can tell me what kind of mosfet this CR8N1 is ?

    Greetings Frans

          Here it is...... hard to read but cannot get a better picture,

          Top connection i have 18.8 volt, bottom left i have 19.1 volt, and bottom right which goes to the battery connector is 0 Volt.

                      Dell E6400 PT434 type Battery Charging Stuck at 1%. Battery Pinouts?
                      by Bowline
                      My question pertains to understanding the control circuity inside a Dell PT434 type battery used in Dell E6400, E6410 and other Dell notebooks?

                      Does anyone have a circuit diagram for the inside of a Dell PT434 battery and/or a description of how the control lines work to control this battery?

                      My reason for asking is I have a battery which I cannot get to charge beyond 1% in a Dell E6410 or E6400.
                      The LED bar graph charge indicator on the battery shows one LED lighted when the info button is pressed.
                      I have tried multiple different Dell power adapters. My Dell...

                      HP ProBook 445 G8 Battery not charging
                      by Julian Bailey
                      Hi all

                      We have in a HP ProBook 445 G8 laptop with AMD Ryzen 7 CPU. When power is connected the power LED light blinks 5 times then stops. Normally HP laptops will blink this LED 10 times as it does a self test when the AC adaptor is inserted. So there must be some sort of short somewhere.

                      The battery doesn't charge, and is erratic on the MM voltage. Bench PSU LED pulsates when the battery is connected also. So the fault must be on the charging circuit?

                      I have gone around the board with a MM and cant find anything

                      Windows shows the battery fine,...

                      Laptop battery charging circuit
                      by piernov
                      1. Some theory
                      1.1. Introduction
                      Almost every laptop has a charging circuit of some sort, that does a few things:
                      • Manages switching between AC adapter and battery power
                      • Manages battery charging and generates power rail to charge battery


                      There are 2 different designs to handle switching between AC adapter and battery power and feeding the system:
                      • Hybrid power boost (HPB) and traditional circuits without power boost (see Warning in HPB section)
                      • Narrow VDC (NVDC)

                      Texas instrument has a nice overview of these technologies with some more details at https:...

                      ThinkBook 15 G3 ACL Not Charging Battery - LA-K602P Board
                      by kodox
                      since i couldn't find schematic or boardview for this model (LA-K062P), i use closest board model found here https://www.badcaps.net/forum/troubl...-and-boardview

                      the schematic share same marking for each component, using same PD-Controller, same BQ25710, the only different is the battery cell used. LA-K061P uses 3S battery while LA-K062P use 4S battery per schematic.
                      what i've done:

                      Razor Blade Steath 13" RZ09-01963 plugged in Not Charging (new battery)
                      by Shinju
                      Hey All!

                      Long time forum member here with a problematic laptop issue!

                      I got a RZ09-0196 with a bloated battery (still worked and charged fine) I pulled the old cell pack out and installed a new cell pack in its place.

                      The laptop would not power on with the new battery installed without the power supply being plugged in.

                      When booting into Win10 (all up to date BTW) I saw the battery icon with 49% plugged in not charging.

                      TL;Dr version, old battery worked, charged but was bloated, installed a new non OEM replacement, laptop/windows...
