    Apple 820-00244not start

    Hello.Have this Apple 820-00244 board that wont start. i dont have QC charger, just usual 5V 1.5A usb charger.

    When i connect it to usb-c port the voltage on fuse is 5V, but after first doubled mosfet i have fluctuating voltage from 5V to 3V

      Yes it needs a 20V charger to work. Use a genuine one.
      Don't just inject 20V into the usb c port! Theres communication between the board and charger. The board will "tell" the charger to go to 20V.

          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...

          Lenovo T460 Only Charges on One Charger
          by motormayhem
          Laptop Question
          Hello,
          I'm working on a Lenovo T460 that has been having trouble charging as of late. Its worked well since I've owned it for a few years. When I went to use it the other day it was dead and wouldn't turn on (was sitting on an Anker 65W GaN charger). After some fiddling with the charger I got it to turn on and start charging, but seemed like the charger was not working as it should (took a few plug and unplug cycles to get it to start charging).

          A day later it was dead again and wouldn't boot/charge no matter what I did. No lights or anything when...

          ISL88739AHRZ ISL88739 Laptop Battery Charger Datasheet
          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...

          Dell Inspiron 7567 LA-D993P odd charger issue
          by Johndill
          Hi, I have a Dell Inspiron 7567 LA-D993P that I've just got running.
          There was corrosion around PU1503 which shorted PC1518 & blew PL1504. (Reference pictures attached)
          I've replaced PC1518 & PL1504 & the laptop is now running however I now have another issue.

          Here are the tested scenarios:

          1. With the laptop running on battery, I plug in the 150W charger & the charger shuts off (no LED, protection mode) but the laptop remains running on battery.

          2. With the laptop off, plug in charger (LED says on) & the front charging...
