    Acer ES1-511 (E15 series) not charging

    Seems to be a few models in the above series exhibiting this issue, some not even a year old, from searches I've done.

    Machine will power on if connected to mains, but will not from battery, even if sufficiently charged.

    Anyone know of a common factor? Faulty mosfet(s)?

      i also have several of the acer ES1 models and they do not charge battery, they run fine on mains but no charge.

      Does anybody else have the same issue, and have some information about it.

                  Re: Acer ES1-511 (E15 series) not charging

                  check mosfets and if they are good change IC(check output IC on pin 5).
                  In my case after i change IC, charging works

                  what IC do you have on board?

                      Re: Acer ES1-511 (E15 series) not charging

                      can i check mosfets on board, or do i have to remove them and test?

                      Charging IC is BQ737..

                      i have 0V on pin 5 - (ACIN) when charger is plugged in. what voltage should be there?

                      thanks for your help

                          Has anybody else had charging issues with Acer ES1 (E15) model laptops?

                              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...

                              Laptop Model: Acer Aspire 3 A314

                              Charging IC: BQ24780 which I have repalced.

                              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.
