              PU4404 is High Side and PU4405 is low side fet. I asked you to check them. Specially notice the voltage on pin4(Gate) of both the fets. I hope you understand now.

                          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...

                          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...

                          Acer A315-41G similar to AN515-42, AC OK Battery OK but not charging

                          Hi guys,
                          I currently trying to figure out why the laptop of my friend did not charge.
                          It is a Acer AN515-42 (Ryzen 5 2500U), I manage to make it works on AC and battery but no charging.
                          At first it was not working on Battery, I discovered that PQ201 was knocked off and replace it => work on battery precharged on another computer.
                          I also checked the small resistors between PQ312 and PQ201 and even if they are ugly values are OK.
                          My issue, when I plug the charger computer off, it drains 0.25A during few seconds with amber light on (charging) then amber light blinks...

                          Issue Description:
                          I'm experiencing an issue with the charging system on this laptop. The BQ24780 charging IC is not working as expected. The main problems are:
                          1. ACDET is missing (0V):, Reading 0V on the ACDET pin.
                          2. ACOK is not present (0V): Is missing as well.
                          3. No SMBus signals (SDA and SCL are missing): The SDA and SCL signals for SMBus communication are not present. There is no clock (SCL) or data (SDA) activity on these lines.
