Claims15
A method of displaying the battery capacity using LEDs on a notebook computer system, the LEDs are being usable to indicate at least one of the actions of the computer drives and keyboard functions, which comprises the steps of:
- transmitting the battery capacity message through an SMB bus to a keyboard controller (KBC) unit;
- providing a sub-routine, which switches from the power management function to the battery capacity display function through the control of a lid switch;
- providing a logic unit that functions according to the control of the lid switch to temporarily stop the action signals of the hard disk drive (HDD) and the floppy disk drive (FDD);
- and
- displaying in different ways for different battery capacities using the LEDs.

- and
- displaying using the LEDs different battery capacities in the following ways:
- flashing the FDD LED when the battery capacity is between 0 and 10%;
- turning on the FDD LED when the battery capacity is between 11% and 19%;
- turning on the FDD LED and flashing the HDD LED when the battery capacity is between 20% and 30%;
- turning on both the FDD LED and the HDD LED when the battery capacity is between 31% and 39%;
- turning on both the FDD LED and the HDD LED and flashing the NUM LOCK LED when the battery capacity is between 40% and 50%;
- turning on all the FDD LED, the HDD LED and the NUM LOCK LED when the battery capacity is between 51% and 59%;
- turning on all the FDD LED, the HDD LED and the NUM LOCK LED and flashing the CAPS LOCK LED when the battery capacity is between 60% and 70%;
- turning on all the FDD LED, the HDD LED, the NUM LOCK LED and the CAPS LOCK LED when the battery capacity is between 71% and 79%;
- turning on all the FDD LED, the HDD LED, the NUM LOCK LED and the CAPS LOCK LED and flashing the SCROLL LOCK LED when the battery capacity is between 80% and 99%;
- and
- turning on all the FDD LED, the HDD LED, the NUM LOCK LED, the CAPS LOCK LED and the SCROLL LOCK LED when the battery capacity is 100%.
A device of displaying the battery capacity using LEDs of a notebook computer system, which utilizes the existing five LEDs. i.e. the HDD, FDD, SCROLL LOCK, CAPS LOCK and NUM LOCK LEDs, of the notebook computer system, along with the depressing of a lid switch and the signal transmission of a keyboard controller (KBC) and an SMB bus, to display the battery capacity;
- wherein the device is characterized in that:
- the device comprises a logic unit to function according to the lid switch to temporarily stop the action signals of the HDD and the FDD;
- and
- all the five LEDs are used to display different battery capacities.
