摘要： A motherboard includes a printed circuit board (10), and at least a power/ground trace (20) formed on the printed circuit board. The trace includes a pair of main lines (14, 24) and at least a protection line (12, 22) connected between the main lines. A width of the main lines is constant and wider than of the protection line. Wherein when a current flowing through the power/ground trace exceeds a maximum current the protection line can endure, the protection line is burnt and disconnected from the main lines, thereby generating less smoke and protecting components connected with the trace of the motherboard from damage due to excess current.

摘要： A controlling circuit for controlling on-off switching of a power supply for a CMOS circuit includes a CMOS circuit (20) and a switch (30). The CMOS circuit includes a first circuit (50) for storing the system time of the computer and a second circuit (70) for storing other system settings of the computer. One terminal of the switch is connected to the first circuit and a power supply (10) in parallel via a resistor (R2). The one terminal of the switch is connected to the second circuit, and another terminal of the switch is connected to ground. When the one terminal of the switch is connected to the another terminal, the data stored in the second circuit is cleared while the system time stored in the first circuit remains.
