Hi everyone,

I'm looking for advice regarding a strange battery issue on my Acer Nitro ANV15-41 (Ryzen 7 7735HS).

A few days ago, my laptop was working completely normally on battery. According to the Windows battery report, it was running on battery power and the charge dropped from around 80% to 67% normally. After that point, the laptop suddenly stopped detecting the battery.

Current symptoms:

Windows shows 100% battery, but the laptop shuts down instantly if I unplug the charger.

BIOS shows "Battery: N/A".

wmic path Win32_Battery get Name,BatteryStatus returns "No Instance(s) Available".

powercfg /batteryreport says "No batteries are currently installed".

The laptop only works when connected to AC power.

No battery is detected in BIOS or Windows.

What happened before the issue:

The problem appeared around the time Windows was installing updates/restarting.

I cannot say with 100% certainty that the update caused it, but the timing matches.

Before that, the battery was functioning normally.

Troubleshooting already done:

Performed a full shutdown using:

​

shutdown /s /f /t 0

Entered BIOS and loaded default settings.

Saved BIOS defaults and rebooted.

Checked BIOS battery status (still shows Battery: N/A).

Generated Windows battery report.

Ran:

​

powercfg /a

Checked Task Manager and fixed some unrelated Windows tray icon issues.

Windows updates completed successfully.

Battery report still says no battery installed.

BIOS still cannot detect the battery.

Additional information:

Laptop is out of warranty.

Battery is internal (non-removable).

Bottom cover has never been opened.

No swelling, overheating, burning smell, or physical damage.

Laptop works perfectly on charger power.

My questions:

Does this sound like a failed battery/BMS?

Could this be a loose battery connector even though the laptop was never opened?

Has anyone seen a BIOS showing "Battery: N/A" and recovered it without replacing the battery?

Is there anything else I should test before visiting an Acer service center?

Any advice would be appreciated.
