Acer Nitro 5 AN515-57-7296 Battery Not Charging After Charging Circuit Repair and Battery Replacemen

Hello Acer Community,
I'm experiencing a frustrating issue with my Acer Nitro 5 AN515-57-7296 laptop, and I'm hoping someone can offer some guidance.
My laptop (originally with an AP18E8M battery) had been unused for about a month. When I tried to turn it on, the fan ran at full speed, I heard a clicking sound, and the laptop shut off. I took it to a repair shop, and the technician diagnosed a charging circuit issue.
After the repair, the laptop would only turn on when the AC adapter was plugged in. The technician then recommended replacing the battery, as they said the old one was weak. I replaced it with a brand new battery.
However, the problem persists. Now, the laptop turns on with the adapter, but the battery doesn't charge. For example, I plugged it in at 12:30 PM when the battery was at 50% and showing as charging. At 1:00 PM, it was still at 50% and still plugged in, but the charge level hadn't changed. When I unplug the adapter, the laptop runs on battery power, and the battery percentage decreases as expected.
The technician has checked the laptop a second time after I reported this issue, but he insists he can find no further problems with the charging circuit.
So, to summarize:

Laptop Model: Acer Nitro 5 AN515-57-7296
Original Issue: Charging circuit failure, clicking sound, fan at full speed.
Repair: Charging circuit supposedly repaired.
Current Issue: Laptop only powers on with the adapter. New battery doesn't charge, even after a second check by the technician.
I've already replaced the battery, and the technician has re-checked the charging circuit, so I'm unsure what the problem could be. Could the repair have been incomplete? Is there a setting I'm missing? Could there be a separate issue at play? Any advice or suggestions would be greatly appreciated.
Thank you for your time and assistance.

UPDATE

I wanted to add some further details regarding the charging issue. I've noticed that the battery percentage never increases, no matter how long the laptop is plugged in. For example, even after an hour or more of being connected to the AC adapter, the battery percentage remains stuck at whatever level it was at when I plugged it in.

Furthermore, I've tested to see if there's some kind of artificial charge cap. If I unplug the adapter and let the battery discharge (for example, from 50% down to 40%), and then plug the adapter back in, the battery percentage simply stays at 40%. It never goes up, even after extended periods of being plugged in. This confirms that the battery isn't hitting some kind of limit or being prevented from charging beyond a certain point. The charging simply isn't working at all.

I've shared this information with the technician, but he still hasn't been able to identify the cause. Any insights or suggestions from the community would be greatly appreciated!"

Hi, did you perform the Full Charge Cycle routine required for each new battery to register its capacity in BIOS and MS ACPI? Failing to do so will result in bad battery data and power issues. If you can't charge the battery run a battery report: Paste this in the command prompt: powercfg /batteryreport and open the report with your Edge browser, right click and select "Print to Microsoft PDF", attach the report to your reply, type @Puraw or use "Quote" when you reply so I will get an alert. Another issue can be the adapter if this is is the original 3-year-old power adapter and not a USB-C charger that is not very likely the problem.

@Puraw How to do a Full Charge Cycle routine

I have attached the battery report.

My adapter is a 3 years old model (Round Type)

Please have a look and let me know if you find any problem.

Hi, that battery worked for 3 years till January 24 (2 weeks ago), so if this is a new battery the history is still from the previous battery. Also Modern Standby is not supported, either by your laptop or the battery. The new battery is not registered in BIOS and MS ACPI protocol.

Connect the adapter and boot to BIOS with F2, check that you have the latest version 1.20 and reset BIOS with F9, save changes with F!0 and exit BIOS. Boot to Windows and disable Fast Startup and Hibernate in "Change what closing the lid does" and in "Change settings currently unavailabke". Reset your power plan in "Edit power plan" and open Device manager, uninstall the 2 battery drivers (see picture below) and reboot, check if the amber battery LED is on and let it charge till the battery LED turns blue, the battery meter should read 100%, wait a few minutes, don't use the laptop yet disconnect all peripherals, shut doen (disconnect) internet, and unplug the power adapter. if the laptop shuts down and/or the battery LED never turned blue you have a power rail failure, either the MOSFETs, socket/cable or the battery died. If the laptop says on work till the system shuts down automatically (5%) and close the lid. Keep the lid closed and charge agian till the amber battery LED turns blue, wait a few extra minites. That's it (one Full Charge Cycle completed).

• Open the Device Manager by searching for it or right-clicking the Start button and selecting Device Manager.
• Click Batteries on the list to expand it and you should see two items: Microsoft AC Adapter and Microsoft ACPI-Compliant Control Method Battery.
• Right-click ON EACH ITEM (BOTH) and choose Uninstall device. Yes, you are uninstalling your laptop's battery drivers, but don't worry because they will automatically be reinstalled when you restart your laptop.
• Shut down your laptop.
• Unplug the power cable from your laptop.
• If your laptop has a removable battery, remove it. My laptop does not have a removable battery. I tried skipping this step but it didn't work, so I removed the bottom panel of my laptop and then removed the battery by disconnecting it from the motherboard.
• Put the battery back in if you removed it.
• Plug in your laptop.
• Power on your laptop.
• Click the battery icon in the system tray and you should see that your laptop is plugged in and charging.

Hi, you have a power rail problem, MOSFETs, bad DC socket, or battery cable, also the battery (Smart chip) could be bad. I recommend bringing the laptop and power adapter to Acer Services in your country to check this.
