  • Publication number: 20230324968
    Abstract: An information handling system includes a memory and a processor. The memory stores data associated with cooling fans and other components within the information handling system. The processor receives a first set of data for a baseline cooling condition within the information handling system, and a second set of data for a current cooling condition. The processor determines whether a first subset of data in the first set of data is substantially equal to a second subset of data in the second set of data. If so, the processor determines whether a baseline device temperature is substantially equal to a current device temperature. If not, the processor determines a first degradation issue within the information handling system based on cooling fans in a first fan zone are operating at full speed, and both a first device temperature increases and a downstream components temperature increase.

  • Patent number: 11689913
    Abstract: This application discloses a terminal roaming method and apparatus. A terminal sends, to a first AP associated with the terminal, an action frame that is used to request to associate with a second AP. A receiver address of the action frame is an address of the first AP, and the action frame further includes an identifier of the second AP. When the terminal receives a response frame sent by the first AP for the action frame, and the response frame indicates that association succeeds, the terminal establishes association with the second AP. The terminal first establishes the association with the second AP by using the first AP, and then changes an operating channel to an operating channel of the second AP. Now the terminal can receive and send data on the operating channel of the second AP.
