Electronic device and method of starting the same

Abstract

A method of starting an electronic device includes: receiving a first wireless signal carrying a first identification data by a wireless receiver before the electronic device enters a normal operating state; comparing the first identification data with a valid data; obtaining an account name and a password according to the first identification data if the first identification data matches the valid data and logging in to an operating system with the account name and the password so as to allow the electronic device to enter the normal operating state; and not logging in to the operating system if the first identification data does not match the valid data.

What is claimed is: 
     
       1. A method of starting an electronic device having a wireless receiver, an embedded controller and a processing unit, comprising the steps of:
 receiving, by the wireless receiver, a first wireless signal carrying a first identification data by the wireless receiver while the electronic device is in a sleep state; 
 comparing, by the embedded controller, the first identification data with a valid data; 
 determining that the first identification data matches the valid data; 
 obtaining, by the embedded controller, an account name and a password according to the first identification data; 
 providing, by the embedded controller, the account name and the password to the processing unit; 
 executing, by the processing unit, the a start procedure of an operating system upon receiving the account name and the password from the embedded controller; and 
 logging in to the operating system, by the processing unit, with the account name and the password so as for the electronic device to enter the a normal operating state. 
 
     
     
       2. The method of  claim 1 , wherein the first wireless signal is from one of an identity card and or a wireless transmitter. 
     
     
       3. The method of  claim 1 , wherein the method further comprises:
 driving the wireless receiver while the electronic device is in the sleep state. 
 
     
     
       4. The method of  claim 1 , wherein, when the first identification data matches the valid data, the step of logging in to the operating system with the account name and the password is preceded by executing a self-test procedure. 
     
     
       5. The method of  claim 1 , wherein the first identification data is the account name and the password. 
     
     
       6. The method of  claim 1 , wherein the first identification data is a username. 
     
     
       7. The method of  claim 1 , further comprising the steps of:
 executing an automatic sleep detecting procedure when the electronic device is in the normal operating state, the automatic sleep detecting procedure comprising the steps of: 
 detecting a second wireless signal regularly by the wireless receiver, wherein the second wireless signal comprises a second identification data; 
 comparing the second identification data with the valid data upon detection of the second wireless signal; 
 keeping the electronic device in the normal operating state when the second identification data matches the valid data; and 
 causing the electronic device to enter a the sleep state when the second wireless signal is not detected or the second identification data does not match the valid data. 
 
     
     
       8. The method of  claim 1 , wherein the embedded controller periodically drives the wireless receiver to receive wireless signals while the electronic device is in the sleep state. 
     
     
       9. The method of  claim 1 , wherein the embedded controller enters the sleep state when the electronic device is in the sleep state, and periodically wakes up to drive the wireless receiver to receive wireless signals while the electronic device is in a the sleep state. 
     
     
       10. An electronic device, comprising:
 a wireless receiver configured to receive a first wireless signal while the electronic device is in a sleep state, wherein the first wireless signal comprises a first identification data; 
 a processing unit; and 
 an embedded controller storing a valid data, configured to perform the following while the electronic device is in the sleep state:
 compare the first identification data with the valid data; and 
 when the first identification data matches the valid data:
 obtain an account name and a password according to the first identification data; and 
 provide the account name and the password to the processing unit; and 
 
 wherein the processing unit is configured to perform the following:
 execute the a start procedure of an operating system upon receiving the account name and the password from the embedded controller while the electronic device is in the sleep state; and 
 log in to the operating system with the account name and the password so as to enter the a normal operating state. 
 
 
 
     
     
       11. The electronic device of  claim 10 , wherein the first wireless signal is from one of an identity card and or a wireless transmitter. 
     
     
       12. The electronic device of  claim 10 , wherein the wireless receiver is configured to keep operating normally in the sleep state. 
     
     
       13. The electronic device of  claim 10 , wherein the first identification data is the account name and the password. 
     
     
       14. The electronic device of  claim 10 , wherein the first identification data is a username. 
     
     
       15. The electronic device of  claim 10 , wherein, when the processing unit is in the normal operating state, the embedded controller executes is configured to execute an automatic sleep detecting procedure, and wherein the automatic sleep detecting procedure comprises:
 detecting a second wireless signal regularly by the wireless receiver, wherein the second wireless signal comprises a second identification data; 
 comparing the second identification data with the valid data upon detection of the second wireless signal; 
 maintaining the normal operating state of the processing unit when the second identification data matches the valid data; and 
 causing the processing unit to execute a sleep procedure when the second wireless signal is not detected or the second identification data does not match the valid data. 
 
     
     
       16. The electronic device of  claim 10 , wherein the embedded controller is configured to periodically drive the wireless receiver to receive wireless signals while the electronic device is in the sleep state. 
     
     
       17. The electronic device of  claim 10 , wherein the embedded controller is configured to enter the sleep state when the electronic device is in the sleep state, and periodically wake up to drive the wireless receiver to receive wireless signals while the electronic device is in a the sleep state.
