    Macbook A1466 2014 not charging with macsafe 2 charger

    I have a macboook air a1466 that stopped charging the battery.

    BAT PINS: with or without ADAPTER IN
    1- GND
    2- GND
    3- GND
    4-0V sense pin
    5-3.42V
    6-3.42V
    7- 8.4V
    8- 8.4V
    9- 8.4V

    AC Adapter plugged in: after a lot of of hours some times start charging
    No BAT Connected- Green to Orange
    AC Adapter plugged in: BAT Connected- no light
    The strange thing, when I tried a mac charger usb-c with usb-c to macsafe 2 adapter works normally and charging.
    Any ideas what’s wrong please?

      Charging macbook pro mid 2014 15" with magsafe 2 60W charger
      by paparazzo79
      Hi guys.
      May I charge this model with 60 W charger?
      I know it requires 80 W to charge, but don't want to buy one.
      If it specifically requires and 60 W can damage macbook and vise versa, I guess I will have to buy 80 W one....

      ASUS X54H laptop thinks it's always charging even with charger unplugged
      by flat-earther
      The charging indicator light on my ASUS X54H laptop is always on even when the charger is disconnected.

      Windows also shows ''Plugged in'' when charger is not connected.

      This problem started year ago gradually, when unplugging the charger the charging light took several seconds to disappear, then minutes, and now almost always on even when unplugged for an entire day.
      Strangely, before sometimes immediately when plugging in the charger the charging light went away, and later came back with it connected.
      If I let battery run out and say it has 3% Windows will...

      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...

      MacBook Air M1 A2337 battery/charging issue
      by drlarsen
      Hello. Sorry for the long post, but I am trying to decide if this is a simple battery replacement, or potentially something more complicated.

      I bought an open box MacBook Air M1 2020 A2337. Seller claimed it was never used. Visually, it appears pristine.

      On arrival, the battery was completely flat. Computer powers up and boots fine. Battery status showing 1% and charging, 1 cycle. coconutBattery showing 0 mAh and ~6 watts.
      After some hours, the battery status did not improve. Restore via DFU did not help.

      I connected the power adapter to a Kill-a-Watt...
