A computer system includes a serial advanced technology attachment dual-in-line memory module (SATA DIMM) device and a motherboard. The SATA DIMM device includes a control chip and an edge connector. The motherboard includes a memory slot and a light emitting diode (LED). When the edge connector is inserted into the memory slot, first power pins, first ground pins, and first indication pin of the memory slot are respectively connected to second power pins, second ground pins, and second indication pin of the SATA DIMM device. The motherboard outputs a voltage to the control chip through the first and second power pins. The control chip detects and calculates the storage capacity of the SATA DIMM device and outputs a control signal to control the LED to turn on or not, for displaying free memory capacity of the SATA DIMM device. |

1. A computer system, comprising:
a motherboard comprising:
a memory slot comprising:
a plurality of first power pins, a plurality of first ground pins, and a first indication pin; anda first light emitting diode (LED) comprising an anode connected to a power source and a cathode connected to the first indication pin; and a serial advanced technology attachment dual-in-line memory module (SATA DIMM) comprising: an edge connector comprising a plurality of second power pins connected to the first power pins, a plurality of second ground pins connected to the first ground pins, and a second indication pin connected to the first indication pin; and a control chip connected to the plurality of second power pins of the edge connector, wherein the control chip comprises a first input output (I/O) pin connected to the second indication pin; wherein when the edge connector is inserted into the memory slot, the first power pins, the first ground pins, and the first indication pin are respectively connected to the second power pins, the second ground pins, and the second indication pin, the motherboard outputs a voltage to the control chip through the first and second power pins, the control chip detects the work states of the SATA DIMM device and calculates the storage capacity of the SATA DIMM device, and outputs a control signal through the first I/O pin according to the storage capacity, to control the first LED to turn on or not for displaying free memory capacity of the SATA DIMM device. |
