    Acer Nitro 5 not charging but working with battery

    Hello Everyone

    First I must say I am trying to learn electronics. I have an Acer Nitro 5. Board is LA-861P. The laptop does not charge but when it has battery life it would power on and work fine. I have use a multimeter to check the charger and I get 19v.

    Input on PBQ3 mosfet is 19v but no output or very low voltage. The voltage on PCZ65 and PCZ48 is 2v and it keep dropping after putting the charger for a few second. Battery pin would give like 0.200v declining.

    If I put the laptop off for like 2-3 months it would start charging again but I need to do this procedure :

    1. Put the charger in the power socket
    2. Power it on
    3. Plug it in the laptop.

    Last time it worked for 3 months after it died because I did not follow those procedures. This is the third time it stop charging.

    Anyone has an idea about what can be the cause ? It is about the same issue as here : https://www.badcaps.net/forum/troubl...er-no-charging but mine would power on with battery.โ€‹

              how to prevent a connected charger from draining battery when not charging?
              by flat-earther
              I have an RC radio handset(Taranis QX7) which doesn't have internal battery charger which means I had to remove the battery every time I needed to charge it.
              So to improve it, I added a 15W USB-C charger board(link) inside and soldered it to the same connector on the PCB where the battery plugs into, great, now I can simply charge it with a USB-C cable.

              but the problem I found is that after the radio sat for two weeks without being used the 2S 18650 battery that I'm using was at 4.2V!
              So the battery is backfeeding the charger and being drained.

              How can I prevent...

              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...

              Strange! Acer laptop not powering on but charging the battery (orange light on when charger and battery plugged in).
              by serious_electron
              Hello Everyone!

              I have an Acer Aspire A315-42 laptop. I generally leave it on for long time by closing down its lid (so it enters the sleep mode). Recently, it rained quite heavily in out area. And the humidity and moisture seem to be high. So one late evening, after I opened the lid and turned on the laptop, it did power on as the blue light turned on but after it booted to the desktop screen, just 5-10 seconds after both the screen and blue light went out and laptop shut down (the blue power light turned orange). And after 2-4 seconds that orange light went off and the laptop died.              ...

              by Document Archive
              The ISL88739 & ISL88739AHRZ are a highly versatile combo battery charger
              configurable for operating as either a Hybrid Power Boost (HPB)
              charger or a Narrow VDC (NVDC) charger, supporting 2-, 3-, or
              4-cell batteries. Both configurations allow the battery to work with
              the adapter together to supply the system load when it exceeds
              the adapter capability, referred to as system Turbo mode. HPB
              charger configuration reverse-boosts battery energy to the system
              bus to help the adapter provide the system power in Turbo mode.
              NVDC charger configuration...

              [Help Needed] Acer Aspire 5 A517-52G โ€“ Removed Onboard RAM, Now Working But Battery Not Charging

              ๐Ÿงต [Help] Acer Aspire 5 A517-52G โ€“ Onboard RAM Removed, BIOS Mod Done, Battery Not Charging


              Hi everyone,

              I have an Acer Aspire 5 A517-52G-53NB laptop.

              The onboard (soldered) RAM was faulty, so I physically removed the chip.
              I also successfully modified the BIOS using the SPD Removal Tool โ€“ the laptop now boots fine and works with an 8โ€ฏGB DDR4 SO-DIMM installed.
              โœ… System status:
              • BIOS mod is done (SPD removed)
              • Laptop boots to Windows normally
              • RAM is detected and stable
              โŒ Problem:


              The battery is not charging:
              • Power adapter
