Abstract

The invention discloses an electronic equipment operation method based on a battery and electronic equipment. The method comprises the following steps that in the condition under a temperature threshold, in the process that corresponding current is output to system load by the battery in accordance with the current requirement of the system load, the output voltage of the battery is monitored until the temperature of the battery is equal to or higher than the temperature threshold; whether the output voltage of the battery is lower than preset voltage is judged; and when the output voltage of the battery is lower than the preset voltage, at least one electronic element is controlled, so as to reduce power consumption and guarantee the output voltage of the battery to be higher than cut-off output voltage. In the scheme, when the monitored output voltage is lowered to a certain degree, the power consumption of the system load is reduced, so as to reduce the current required by the system load, so that the current spike is prevented from being generated, thereby guaranteeing the output voltage of the battery to be kept higher than the cut-off output voltage, and the problem of system poweroff caused by the current spike during operation of the electronic equipment at low temperature is effectively solved.

Description

technical field [0001] The invention relates to the technical field of communication equipment, in particular to a method for operating an electronic equipment based on a battery and the electronic equipment. Background technique [0002] Compared with desktop computers, notebook computers have the advantages of small size, light weight, and portability, so they are widely praised. Among them, the notebook computer can use the characteristics of the notebook battery to work without an external power supply, bringing it a portable foundation. [0003] However, during the operation of a notebook computer using a battery, especially during the boot process, most of the time the current required by the notebook computer is relatively stable and the current value is relatively small, but at a certain moment, multiple electronic components inside the notebook computer start at the same time or When the current value required by an electronic component increases sharply, it will l...
