Patent number: 10372914Abstract: For validating computing device firmware, systems, apparatus, and methods are disclosed. The apparatus includes a processor, and a memory that stores code executable by the processor, the code including code that acquires a firmware manifest for locally stored firmware, authenticates a digital signature of the firmware manifest, and validates contents of the locally stored firmware using the firmware manifest. The apparatus may also include code that generates a local firmware manifest from the firmware, wherein validating the contents of the firmware includes comparing the local firmware manifest to the firmware manifest. In certain embodiments, the apparatus may indicate, to a user, one of success and failure of the firmware validation. The firmware manifest may be a location-specific firmware manifest corresponding to a geographical location of the apparatus and/or computing device including the locally stored firmware.Type: GrantFiled: June 24, 2015Date of Patent: August 6, 2019Assignee: LENOVO (SINGAPORE) PTE. LTD.Inventors: Steven D. Goodman, Mikio Hagiwara, William Laurence Jaeger, Jr., Eitaroh Kasamatsu, Kohsuke Ohtani, Randall Scott Springfield, David Burke Stone, Christopher Aaron Whitesock

Patent number: 9292302Abstract: Provided is a method for temporarily skipping a secure boot function. A computer is configured so that a secure boot function is set as enabled by default. Depression of a power button of the computer in a power-off state generates a startup signal. At the time of startup from S4/S5 state, a switch is turned ON and PP bit indicating physical presence is set at a register. Depression of a specific key on a keyboard causes DE bit to be set at a register. When PP bit and DE bit are found, UEFI firmware stored in a firmware ROM temporarily skips integrity validation of a boot program only for boot this time.Type: GrantFiled: January 8, 2013Date of Patent: March 22, 2016Assignee: Lenovo (Singapore) PTE. LTD.Inventors: Ken Sasaki, Eitaroh Kasamatsu, Yusaku Morishige, Kohsuke Ohtani

Patent number: 8566951Abstract: Methods and apparatus are provided for inhibiting data writing to an optical disc drive connected to a computer. A BIOS confirms presence of a security function of an optical disc drive. When the optical disc drive possesses the security function, the BIOS delivers a command to the optical disc drive to set it to a read-only mode. The optical disc drive that has received the command sets the drive per se to operate in the read-only mode. Since a command for setting it to the read-only mode and a command for releasing it are delivered to the optical disc drive only by the BIOS, when a control is transferred to an Operating System (OS), setting of the read-only mode cannot be released by the OS and other OS's, or application software.Type: GrantFiled: April 25, 2008Date of Patent: October 22, 2013Assignee: Lenovo (Singapore) Pte. Ltd.Inventors: Yasuhiro Horiuchi, Kohsuke Ohtani, Kazunobu Umeda

Patent number: 5822597Abstract: A information processing system which enters power management mode when a predetermined time has elapsed since a last user input (or a last processing operation), adjusts the predetermined time according to the action of the operator in response to entering the power mode. If the user transfers back to normal mode quickly the predetermined reference time is increased. If the user responds only after a delay period the predetermined reference time is decreased. By so adjusting the predetermined time a better balance is achieved between energy saving and user convenience for a current level of operator attention to the computer.Type: GrantFiled: May 23, 1996Date of Patent: October 13, 1998Assignee: International Business Machines Corp.Inventors: Seiichi Kawano, Kohsuke Ohtani, Tomoki Maruichi, Yasunori Maezawa, Takashi Oshiyama
