Abstract

A system performance control device is provided. The system performance control device includes a battery and a controller. The controller is coupled to the battery to obtain battery information from the battery. When the controller detects that the battery capacity of the battery is at a first level according to the battery capacity information, the controller adjusts system performance of the system performance control device to a first setting value. When the controller detects that the battery capacity of the battery is at a second level according to the battery capacity information, the controller adjusts the system performance of the system performance control device to a second setting value, wherein the first level is greater than the second level, and the first setting value is higher than the second setting value.

Claims

1. A system performance control device, comprising:

a battery; and

a controller, coupled to the battery to obtain battery information from the battery;

wherein when the controller detects that a battery capacity of the battery is at a first level according to the battery capacity information, the controller adjusts system performance of the system performance control device to a first setting value, and when the controller detects that the battery capacity of the battery is at a second level according to the battery capacity information, the controller adjusts the system performance of the system performance control device to a second setting value, and

wherein the first level is greater than the second level, and the first setting value is higher than the second setting value.

2. The system performance control device of claim 1, wherein the controller adjusts the system performance by adjusting a backlight brightness of a backlight module of the system performance control device.

3. The system performance control device of claim 1, wherein the controller adjusts the system performance by disabling one or more connection ports of the system performance control device.

4. The system performance control device of claim 1, wherein the controller adjusts the system performance by adjusting a power setting of a processor of the system performance control device.

5. The system performance control device of claim 1, wherein the controller adjusts the system performance by adjusting data access speed of the system performance control device.

6. A system performance controlling method, applied to a system performance control device, and comprising:

obtaining battery information from a battery of the system performance control device;

adjusting system performance of the system performance control device to a first setting value, in response to a battery capacity of the battery is at a first level according to the battery capacity information; and

adjusting the system performance to a second setting value in response to the battery capacity of the battery is at a second level according to the battery capacity information,

wherein the first level is greater than the second level, and the first setting value is higher than the second setting value.

7. The system performance controlling method of claim 6,

wherein the system performance is adjusted by adjusting a backlight brightness of a backlight module of the system performance control device.

8. The system performance controlling method of claim 6,

wherein the system performance is adjusted by disabling one or more connection ports of the system performance control device.

9. The system performance controlling method of claim 6,

wherein the system performance is adjusted by adjusting a power setting of a processor of the system performance control device.

10. The system performance controlling method of claim 6,

wherein the system performance is adjusted by adjusting data access speed of the system performance control device.
