          Works Individually on battery and charger.
          Battery Changed ISL6257, 4407a ichips also changed. No Progress
          Works Initial bit but after a minute or so, operates from battery only.

              Check 19 volt in mosfet and battery charging voltage out mosfet.................

                  Initially all voltages are ok 19v. Later On, shows 12v relative only at the voltage load.

                      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...

                      Acer Aspire 5 N20C5 - no power, not charging. Motherboard FH5AT LA-K091P
                      by gfosterCA
                      Good afternoon all.

                      After verifying 19V source and testing for short on the DC charge jack, kept hunting..

                      Pin 5 of PQB3 shows 19V.
                      Pin 4 of PQB3 seems to from 0.3V down to 0, and repeat.
                      Pin 1-3 of PQB3 sit around 0.03V down to 0.

                      _____

                      Pins 5+ on PQB4 appear to be shorted to ground.

                      Voltage injection shows inductor PL501 and PU501 getting hot.

                      For kicks and giggles, removed the inductor PL501, and short at PQB4 is no longer. Would stand to reason that it's on the side of PU501. Side effect: battery...

                      Acer Nitro 5 (EH5VF motherboard) all works except battery charging

                      Hi all,

                      Another puzzle if you are so inclined. Attached PCB/Schems.

                      Background:

                      This unit came to me as "no power". Simple visual inspection revealed a blown up PQB11. I replaced it along with PQB12 just out of standard procedure of replacing them as pairs, and even though it fought me tooth and nail I was able to get a new one in and the board booted fine first try after that.

                      I've since tested the laptop to boot and even stress tested; no issues whatsoever. However, battery won't charge. It will work off the battery no problems...
