Abstract
A server motherboard includes a protective film, a substrate, and a power supply circuit. An equivalent electrical parameter of the protective film changes as a shape of the protective film changes. The shape changes when a temperature of the server mother board is greater than a predetermined temperature. A portion of at least one side surface of the substrate is covered by the protective film. The power supply circuit is electrically connected to the protective film and configured to detect the equivalent electrical parameter of the protective film. The power supply circuit stops outputting a power supply voltage to the substrate when a change of the equivalent electrical parameter is detected.
Claims20
A server motherboard, comprising:
- a protective film, an equivalent electrical parameter of the protective film changing as a shape of the protective film changing, and the shape changing in response to a temperature of the server mother board being greater than a predetermined temperature;
- a substrate, a portion of at least one side surface of the substrate being covered by the protective film;
- and
- a power supply circuit electrically connected to the protective film and configured to detect the equivalent electrical parameter of the protective film, the power supply circuit stopping outputting a power supply voltage to the substrate in response to detecting a change of the equivalent electrical parameter.
A server, comprising:
- a server motherboard including:
- a protective film, an equivalent electrical parameter of the protective film changing as a shape of the protective film changes, and the shape changing in response to a temperature of the server mother board being greater than a predetermined temperature;
- a substrate, a portion of at least one side surface of the substrate being covered by the protective film;
- and
- a power supply circuit electrically connected to the protective film and configured to detect the equivalent electrical parameter of the protective film, the power supply circuit stopping outputting a power supply voltage to the substrate in response to detecting a change of the equivalent electrical parameter;
- and
- a communication interface arranged on the server motherboard.
A power supply control method, comprising:
- detecting an equivalent electrical parameter of a protective film in a server motherboard, the equivalent electrical parameter changing as a shape of the protective film changes, the shape changing in response to a temperature of the server motherboard being greater than a predetermined temperature, and the protective film covering a portion of at least one side surface of a substrate of the server motherboard;
- and
- in response to detecting a change of the equivalent electrical parameter, stopping a power supply circuit of the server motherboard from outputting a power supply voltage to the substrate.
