Abstract:
A computer system includes a system part, a connector to which an external device is connected, a communication unit which performs communication with the external device, and a control unit which is connected between the connector and the communication unit to monitor a state of a predetermined recognition signal applied from the external device when the system part is in a standby mode. The control unit performs a predetermined function corresponding to the monitored state of the recognition signal. When the system part is in the standby mode, the system part may be switched to an operation mode based on the recognition signal from the external device. Additionally, a predetermined charging power is output to an external device in response to the predetermined recognition signal applied from the external device connected to the connector while the system part exists in the standby mode.
Abstract:
A memory controller, a PCB and a computer system employing the memory controller, and a memory adjusting method using the memory controller. The memory controller interfaces data reading from and writing to a memory and includes: a characteristic estimating part estimating a characteristic of a memory output signal outputted from the memory for the data reading and writing; and a characteristic adjusting part controlling the memory so that the characteristic of the memory output signal is within a predetermined reference range if the characteristic of the memory output signal estimated by the characteristic estimating part is beyond the predetermined reference range.

Abstract:
The present invention relates to a computer including a first output port, a first video signal generator to generate a first video signal having a predetermined format, a second video signal generator detachably connected to the computer and to generate a second video signal having the same format as the first video signal; and an output selector to output at least one of the first video signal and/or the second video signal through the first output port when the second video signal generator is connected to the computer. Thus, the present invention provides a computer with a low profile graphic card, which enables implementation of a dual monitor and promotes space utilization of a motherboard.
