摘要： An information handling system includes a wireless management controller having a first wireless network interface used to establish a secure short-range wireless network connection between a management controller and a mobile device. A second wireless network interface establishes a peer-to-peer wireless network connection between the management controller and the mobile device. The management controller stores a secure shell public key received from the mobile device through the secure short-range wireless network connection. The management controller randomly identifies a port number for the peer-to-peer wireless network connection, and disables network traffic through other ports associated with the peer-to-peer wireless network connection. The management controller also transmits a media access control address, the port number, and a host fingerprint to the mobile device through the secure short-range wireless network connection, and receives an access request from the mobile device on the port number of the peer-to-peer wireless network connection after the mobile device authenticated the media access control address and the host fingerprint Determining whether the mobile device is authentic through a secure shell negotiation based on the received secure shell public key. In response to the determination that the mobile device is authentic identifying a group owner of the peer-to-peer wireless network connection based on a negotiation with the mobile device. After the establishment of the peer-to-peer wireless network connection, the management controller may communicate packets with the mobile device on the port number of the peer-to-peer wireless network connection, where outbound packets are encrypted and inbound packets are decrypted.

摘要： An information handling system includes a first node configured to generate a random alphanumeric string, to receive a cipher text and a key from an enterprise key management server, and to decrypt the cipher text using the key and an algorithm to generate a first decrypted value. The first node compares the random alphanumeric string with the first decrypted value to verify the key that is received at the first node. A second node receives the cipher text, the key, and the algorithm from the first node in response to the first decrypted value matching the random alphanumeric string. The second node decrypts the cipher text using the key and the algorithm to generate a second decrypted value, and the first node compares the second decrypted value with the random alphanumeric string to verify the key that is received at the second node. A self-encrypting drive receives the key from the second node in response to the second decrypted value matching the random alphanumeric string, and uses the key upon authentication of the key by the second node.

摘要： A chassis includes power supply units configured to be a primary source of power for several information handling systems. A chassis management controller monitors a power capacity of the power supply units, and sends a measure of first available power of the power supply units to one of the information handling systems. If the power limit of a sled connector is at least equal to the first power requirement of the information handling system, then it may be determined whether a total power available for the information handling system is at least equal to the first power requirement of the one information handling system. If the total power available for the information handling system is at least equal to the first power requirement of the information handling system, then the information handling system may be powered on.

摘要： A method may include executing basic input/output system (BIOS) instructions to initialize an information handling system. The initialization may include generating a hot-plug detect (HPD) override request. The method may further include receiving the HPD override request at a general purpose input/output (GPIO) device. In response to receiving the HPD override request, the GPIO may assert an active-low signal at an interconnect electrically connected to a HPD terminal of a graphics display receptacle, the receptacle for coupling a graphics processing unit to a graphics display device.

摘要： An information handling system includes a cooling fan, a voltage regulator, and a slew rate controller. The voltage regulator is configurable to drive a power device with a selectable slew rate. The slew rate controller directs the voltage regulator to change the selectable slew rate in response to determining the operating condition of the cooling fan.

摘要： An information handling system includes a display device, a camera, and a processor. The camera captures an image including first and second observers in a field of view in front of the display device. Based on the captured image, the processor determines a first location of the first observer and a second location of the second observer. Based on the first and second locations, the processor determines a first set of pixels located within a primary field of view for the first observer, and a second set of pixels located within a second field of view for the second observer. The processor calculates a viewing legibility adjustment for the second set of pixels. Based on the viewing legibility adjustment, the processor adjusts a contrast ratio for the second set of pixels to below a viewing threshold level.

摘要： A typing profile based mood sensing system may comprise a processor receiving a user identification associated with a personal typing profile identifying a repeated pattern of values for a combination of previously recorded haptic hardware typing or touch behavior parameters, and a piezo haptic keyboard controller operably connected to piezo electric elements situated beneath keys of the piezo keyboard detecting current haptic hardware typing or touch behavior parameters describing deformation characteristics for the piezo electric elements. The processor may compare the user personal typing behavior profile against the current haptic hardware typing or touch behavior parameters to identify a user personal typing behavior profile value change, and associate the change with a mood-based haptic keyboard setting adjustment. The piezo haptic keyboard controller may apply the mood-based haptic keyboard setting adjustment to operation of the haptic keyboard or touchpad.
