Put my laptop on sleep (plugged in) for few hours, came back and saw the power led (orange colour) blinking every 5 seconds with 0% charge. The laptop turns off immediately when I unplug. Tried all methods from the community (hard resetting, uninstalling Microsoft ACPI, poking manual battery reset button using a paper clip) but nothing worked. Read somewhere that maybe the battery is completely dead but the laptop's just 2 years old with 23% battery wear level (checked using HWMoniter, charge level is 0%). I do battery calibrating every month so the wear level isn't totally off.
I've no clue what to do and I need this laptop very much for my work. Does anyone know what to do here?
