hi everyone, i have a problem with my 2 year old acer nitro 5 AN515-57. While I was playing a game and plugging in the charger, my computer's battery was full, then suddenly the laptop turned off. When I turned it back on, I saw that my computer's battery was at 0%. I unplugged the charger but the laptop still ran without turning off. I still left the laptop charging but the battery did not turn on and was still stuck at 0%. Can anyone tell me what the problem is and how to solve it. Thank you very much

    This is probably caused by constantly unplugging the power adapter, lauded (also on this forum) as the "Holy Grail" to battery longevity while unfortunately the opposite is often achieved, IMO you should leave the battery plugged in 24/7 to make sure the battery remains charged 100%. Restricting battery charging either by unplugging or by monitoring software like Acer Care Center, battery Calibration/80% battery charge limiting have undesirable effects on BIOS, MS ACPI Battery control and Windows Power Plan-Modern Standby protocol. Maybe you never made a complete charge cycle (5-100% battery charge) so a wrong battery capacity is registered in Windows from the get-go.

    Your laptop model doesn't have a reset pinhole so all you can try is reset the CMOS and uninstall the 2 battery drivers and just reboot, try first to uninstall the 2 MS power drivers in Device Manager (red circle picture) and reboot, if the charging issue persists try the procedure at the bottom.

    Power drain + CMOS reset: Open the back of the laptop and disconnect the battery cable from the motherboard. Locate the CMOS module (with 2 twisted wires Red and Black, left side under the battery) and remove the coin battery. Shorten the +/- terminals inside the CMOS capsule for 2 seconds with a bended paperclip and put the coin battery back with the + sign facing up, close the CMOS capsule. Unseat the 2 Ram modules and firmly secure back in the 2 slots. Next, press the Power Button on the keyboard for 10-15 seconds after that reconnect the battery cable to the motherboard. Close the laptop, plug-in the adapter and try to boot.
