Over about 8 hours with the lid of my laptop closed (sleep mode on battery) the battery will die.
I assumed that setting the laptop to shutdown at critical battery level would stop this. But the device just doesn’t shutdown at critical.
What can I do to improve the battery life while in sleep mode? Is there a sleep mode that will use less power? Why doesn’t the device shutdown when the battery hits critical, while the device is in sleep mode?
