Abstract

In a method of upgrading an operating system of an electronic device, the electronic device sends an informing message to inform a basic input-output system (BIOS) of the electronic device, when the operating system is determined to be upgraded by the electronic device. Once the electronic device is wakened from a sleep mode by the BIOS, the electronic device upgrades the operating system, and controls the electronic device to enter the sleep mode when the operating system is upgraded.

Claims

1. A method for upgrading an operating system using an electronic device, the electronic device comprising a basic input-output system (BIOS), the method comprising:

detecting whether the operating system needs to be upgraded;

sending an informing message to inform the BIOS when the operating system is determined to be upgraded;

receiving a wakening message from the BIOS that the electronic device is wakened from a sleep mode by the BIOS;

upgrading the operating system when the wakening message is received; and

controlling the electronic device to enter the sleep mode when the operating system has been upgraded.

2. The method of claim 1, wherein the operating system is determined to be upgraded when an automatic upgrade management program is included in a list of active processes of a task manager of the electronic device.

3. The method of claim 2, wherein the automatic upgrade management program is inactivated before the informing message is sent to the BIOS.

4. The method of claim 1, wherein the BIOS wakens the electronic device by steps of:

setting an upgrading flag for the electronic device when the informing message is received;

activating a timer to calculate a time period of the electronic device is in the sleep mode after the upgrading flag has been set; and

wakening the electronic device from the sleep mode when the time period is greater than a predetermined value.

5. The method of claim 4, wherein the BIOS further inactivates a display and a fan of the electronic device when the electronic device is wakened.

6. The method of claim 5, wherein the BIOS inactivates the display by setting a brightness value of the display equal to zero, and inactivates the fan by setting a value of Pulse Width Modulation of the fan equal to zero.

7. An electronic device, comprising:

a basic input-output system (BIOS);

at least one processor; and

a storage device storing a computer-readable program including instructions, which when executed by the processor, causes the processor to;

detect whether the operating system needs to be upgraded;

send an informing message to inform the BIOS when the operating system is determined to be upgraded;

receive a wakening message from the BIOS that the electronic device is wakened from a sleep mode by the BIOS;

upgrade the operating system when the wakening message is received; and

control the electronic device to enter the sleep mode when the operating system has been upgraded.

8. The electronic device of claim 7, wherein the processor determines the operating system needs to be upgraded, when an automatic upgrade management program is included in a list of active processes of a task manager of the electronic device.

9. The electronic device of claim 8, wherein the processor further inactivates the automatic upgrade management program before sending the informing message to the BIOS.

10. The electronic device of claim 7, wherein the BIOS wakens the electronic device by steps of:

setting an upgrading flag for the electronic device when the informing message is received;

activating a timer to calculate a time period of the electronic device is in the sleep mode after the upgrading flag has been set; and

wakening the electronic device from the sleep mode when the time period is greater than a predetermined value.

11. The electronic device of claim 10, wherein the BIOS further inactivates a display and a fan of the electronic device when the electronic device is wakened.

12. The electronic device of claim 11, wherein the BIOS inactivates the display by setting a brightness value of the display equal to zero, and inactivates the fan by setting a value of Pulse Width Modulation of the fan equal to zero.

13. A non-transitory storage medium having stored thereon instructions that, when executed by a processor of an electronic device, causes the processor to perform a method for upgrading an operating system of the electronic device, the electronic device comprising a basic input-output system (BIOS), the method comprising:

detecting whether the operating system needs to be upgraded;

sending an informing message to inform the BIOS when the operating system is determined to be upgraded;

receiving a wakening message from the BIOS that the electronic device is wakened from a sleep mode by the BIOS;

upgrading the operating system when the wakening message is received; and

controlling the electronic device to enter the sleep mode when the operating system has been upgraded.

14. The non-transitory storage medium of claim 13, wherein the operating system is determined to be upgraded when an automatic upgrade management program is included in a list of active processes of a task manager of the electronic device.

15. The non-transitory storage medium of claim 14, wherein the automatic upgrade management program is inactivated before the informing message is sent to the BIOS.

16. The non-transitory storage medium of claim 13, wherein the BIOS wakens the electronic device by steps of:

setting an upgrading flag for the electronic device when the informing message is received;

activating a timer to calculate a time period of the electronic device is in the sleep mode when the upgrading flag has been set; and

wakening the electronic device from the sleep mode when the time period is greater than a predetermined value.

17. The non-transitory storage medium of claim 16, wherein the BIOS further inactivates a display and a fan of the electronic device when the electronic device is wakened.

18. The non-transitory storage medium of claim 17, wherein the BIOS inactivates the display by setting a brightness value of the display equal to zero, and inactivates the fan by setting a value of Pulse Width Modulation of the fan equal to zero.
