1, please recall this phenomenon only once, or often? If it occurs only once, it may be a temporary condition while the system is running. If this phenomenon occurs every time, then in the black screen state when the battery is running out of power, please wait patiently for a while, then the machine is likely to automatically enter the sleep or hibernation state and then shut down, so please do not dial the battery immediately after the black screen.
2, please open the control panel -- Power options -- change plan Settings -- change advanced power Settings, find \"battery\" in the box below, click the number in front of it, if you set the \"Use battery\" option under \"critical level battery operation\" or \"low level battery operation\" to sleep or hibernate, Then when the battery reaches the set battery level, it will go to sleep or sleep.
