Lenovo IdeaPad Gaming 3 stuck at 0% charging + blinking white light

I have a Lenovo IdeaPad Gaming 3 (Ryzen 5 7535HS).

Last night I was downloading something and left the laptop without charging. This morning, the battery is stuck at 0% and won’t charge at all.

Symptoms:

Charging stuck at 0%

White light on power button is blinking

Laptop shuts off instantly when unplugged

Charger is plugged in but no increase in battery

Things I’ve tried:

Restarting multiple times

Reinstalling battery drivers (AC adapter & battery)

Checked battery settings (no conservation mode issue)

Is this likely a dead battery or something else like charger/motherboard issue? Any fixes I should try before replacing the battery?
