1. A method for saving data on the basis of the remaining capacity of a battery comprising:
- a first step for storing the present system status data into a memory in a suspend mode conversion and confirming continuously the remaining capacity of the battery;
a second step for transmitting and storing the data stored in the memory to a backup server via a data communication network when the confirmed remaining capacity of the battery is below a reference value; and
a third step for returning to the suspend mode after the data is saved to the server.

Abstract
The present invention discloses a method for saving data including system status data stored in a memory to a backup server via a data communication network if the remaining capacity of the battery is not sufficient, by confirming continuously the remaining capacity of the battery, in a suspend mode in a computer system. Accordingly, the present invention previously prevents important data from losing although the system-down is occurred abruptly by the perfect discharge of the battery.

11. In a portable computer system which resume operations from a suspend mode, a method for resuming the operations comprising:
-
a first step for checking whether system status data just before the suspend mode is saved in a backup server; a second step for connecting to the backup server via a data communication network and receiving the system status data saved in the backup server according to the checking result; and a third step for returning to the state prior to the suspend mode using the received system status data. - View Dependent Claims (12, 13, 14)

15. A method for resuming operations for a portable computer system having a CPU, comprising:
-
completely discharging the battery; charging the completely discharged battery by a user via a power-on mode of the portable computer system to control a power controller of the portable computer system to supply system power and suspend power to the portable computer system; discriminating whether backup-information is set as an enable state by searching a specific BIOS register of the CPU; and confirming if portable computer system status data exists in a computer random access memory if the backup information is set as an enable state.

16. A method of saving data on the basis of the remaining capacity of a battery and for resuming operation for a portable computer system having a CPU, comprising
storing the present system status data into a memory in a suspend mode conversion and confirming continuously the remaining capacity of the battery; -
transmitting and storing the data stored in the memory to a backup server via a data communication network when the confirmed remaining capacity of the battery is below a reference value; and returning to the suspend mode after the data is saved to the server; completely discharging the battery; charging the completely discharged battery by a user via a power-on mode of the portable computer system to control a power controller of the portable computer system to supply system power and suspend power to the portable computer system; discriminating whether backup-information is set as an enable state by searching a specific BIOS register of the CPU; and confirming if portable computer system status data exists in a computer random access memory if the backup information is set as an enable state.
