A control circuit for booting a number of devices in a certain order includes two delay circuits and three switch circuits, the first switch circuit and the first delay circuit receiving a power good signal and a voltage signal from a power supply unit and thus allowing a first device to boot and the first delay circuit outputting a first delay signal after a set time, to the second switch circuit and the second delay circuit, which repeat the process of the first delay circuit and switch circuit, to boot the remaining devices.

Control circuit for controlling devices to boot sequentially

A serial advanced technology attachment dual in-line memory module (SATA DIMM) device includes a circuit board. A storage chip is arranged on the circuit board and stores a first firmware. A memory is arranged on the circuit board and stores a second firmware. A control chip is arranged on the circuit board and connected to the memory, to read the second firmware from the memory and load the second firmware in the storage chip when the first firmware stored in the storage chip is damaged. The control chip is also connected to the storage chip, to control the storage chip to read or to write data.

When a measured current of a resistor is less than a preset current value after a device is inserted into a memory slot, a control chip and a storage chip does not receive voltages. When the measured current is not less than the preset current value and a count time reaches a preset time value, the control chip and the storage chip receive voltages, to read or write data. When measured current of the resistor is not less than the preset current value after the device is removed from the memory slot, the control chip and the storage chip receive voltages, to backup data. When the measured current is less than the preset current value and the count time reaches the preset time value, the control chip and the storage chip do not receive voltages.

A draining apparatus for a keyboard of an electronic device includes a base for slantingly supporting the keyboard and a protecting film to be covered on the keyboard. The protecting film includes a waterproof sheet and a flange protruding up from edges of the waterproof sheet. The flange defines an outfall adjacent to a bottom end of the flange. In case liquid is spilled on the protecting film, the water may flow downward and islet out through the outfall.
