If you see a flashing low battery indicator

If the low battery indicator flashes red, your computer's battery has low charge (typically around 1%) and isn't connected to a power adapter. The flashing low battery indicator might also appear if your Mac is connected to a lower-power adapter than the adapter that came with it.

The indicator flashes for around eight seconds, and then your Mac goes to sleep.

To wake your Mac, connect it to the right power adapter and then press any key on its keyboard. It should wake up immediately. If you're using a different power adapter than the one that came with your Mac, it might take longer for it to charge enough to wake up.

If you see a solid (not flashing) low battery indicator

If the low battery indicator appears steadily for around eight seconds, your computer's battery is nearly empty and isn't connected to a power adapter. After eight seconds, your Mac goes to sleep.

To wake your Mac, connect it to the right power adapter. It might need some time to charge before you can wake it up (longer if you're using a different power adapter than the one that came with your Mac). After your Mac has sufficient charge, press any key on its keyboard to wake it up.

If your display is black

If your computer's battery is completely out of charge (at 0%), the display is black because your Mac is sleeping or shut down.

To wake your Mac, connect it to the right power adapter. It will need several minutes to charge before you can wake it up (longer if you're using a different power adapter than the one that came with your Mac). After your Mac has sufficient charge, press any key on its keyboard to wake it up.
