Abstract
In implementations of the subject matter described herein, a device is provided. The device comprises a power source and a display. The device also comprises a buffer in communication with the display. The buffer is configured to store information to be displayed on the display. The device further comprises a power management unit. In a power-off mode of the device where remaining capacity of the power source is below a threshold, the power management unit powers the display and the buffer, so that the display can display the information stored in the buffer. In this way, even if the device is in the power-off mode due to the low capacity of the power source, the display can still present useful information to the user.
