OK fully discarge and charge the battery measure the battery capacity via batterybar if you need the pc to work with: when full, disconnect battery carefully while the pc is still on and plugged in and just let go into sleep mode when not needed. 2 days later turn off, plug the battery into the pc, boot, disconnect power and measure the battery via batterybar report back
Do you have any guesses what could cause battery drain if it’s not the battery itself? I am a bit hesitant to open the laptop again to disconnect the battery – it has too many screws 🙂 Is there any possible bios setting which would prevent components from draining power in off state?
