    HP820 G1 Not charging unless powered off

    Hi guys.
    have this weird laptop that only charges battery if powered off.
    Also, if battery is not present, laptop doesn't power on (flash grey led at 1 Hz)...

    Any ideas?

    Best regards,
    David

      Check first and second mosfet for internal short and give the readings from the pins on your charging ic.

          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...

          HP Probook 470 G4 - Power and Charging Problem
          by Scoff
          Looking for some help with this one if anybody can assist please? I have an HP Probook 470 G4 Laptop which recently started to intermittently failing to turn on, with intermittent white LED light(charging LED) by the charging port when it should have been charging and showing an orange LED instead. Definitely some sort of gradual failure. Now the laptop fails to power on at all, no charging LED, no Power Button LED either - seemingly dead.
          Stripped down to the bare motherboard. The original HP battery, when disconnected from the motherboard, is reading 0.00v - possibly some sort of protection...

          Help with trying to fix phone that is not charging (Pics inside)
          by SluggerB
          I have two TCL A30 phones.

          Old Phone: This phone worked fine for years, then stopped charging If you plugged a charger into it, the phone would make the charging sound, the phone would tell you it is charging, but the battery icon would not have the charging symbol in it and the battery would not charge.I tried new battery, same behavior.

          New Phone: Works fine, bought as a donor board to try and repair Old Phone

          My interest here is to repair Old Phone, using components parts off New Phone if needed. I am not interested in replacing Old Phone with New Phone....

          Acer Nitro 5 AN515-45 not charging
          by CPUFiddler
          Hi there. I am trying to repair an Acer Nitro 5 AN515-45 and it's giving me some trouble. I have access to SMD rework station, variable power supply, digital oscilloscope, thermal camera, multimeter, stereo microscope.
          This laptop will boot and run from the power brick and/or the internal battery, but it will not charge the battery. NirSoft BattInfo tells me the charge/discharge currents, so I'm confident in saying that it's not charging. In addition, there's no increase in voltage at the battery connector when the laptop thinks it's charging, not even a few millivolts.
          I've downloaded...

          Zbook 15u G6 (PR/ID 4YW47AV) not charging
          by alfanikos
          Laptop stopped charging and battery was emptied.

          Initially thought that it was the battery that failed, since the battery symbol was indicated in the screen when laptop was switched on.

          New original HP battery was ordered and installed. Laptop started without issue.

          1. When power adapter 3,5 mm is connected Charging led is blinking 8 times white and stops. No Charging at all.

          2. USB charger is connected and Charging led lighst orange . No charging at all

          New battery is exhausted slowly-slowly (having 3%)
