If a user forgets the power-on password of his computer, he can depress the “enter” key or “access” key once to cause the BIOS to locate the power-on password in memory and attempt to unlock the HDD using the power-on password to boot a secure O.S. The HDD password either can be the same as the power-on password or the HDD can recognize the power-on password for the limited purpose of allowing access to the secure O.S. In any case, the secure O.S. is booted for password reset.

A system, method, and program product is provided that executes a start sequence of an information handling system that includes a hardware based TPM. Multiple PCRs are stored in the TPM and are initialized to a predetermined state when the start sequence commences. During execution of the start sequence, software modules, including a hypervisor, are loaded the system's memory. PCR values resulting from the loading of the software modules are calculated. The resulting PCR values are compared with expected PCR values. If the PCR values match the expected PCR values, then a virtual environment is created under the hypervisor. The virtual environment includes a VM and a virtual trust platform module (vTPM) that is used by the virtual machine to satisfy the virtual machines TPM requests.

An apparatus, system, and method are disclosed for protecting hard disk data in multiple operating system environments. The present invention restricts access of a hard file to a range of logical addresses using a controller module configured to access a hard file in response to a request for a logical address, a set zero module configured to add an offset value to each request for a logical address on a hard file, and a set max module configured to set a maximum logical address accessible on a hard file. The invention limits access to a lower protected area with logical addresses below the range of logical address and a host protected area with logical address above the range of logical addresses.

The present invention relates to a method for method or system which is able to control access to a new computer user password reset. The system is preloaded with a random password that does not needed to be known by anyone. There are two main situations in which this method will be used. The first situation involves a locally managed password and account where the user does not log in to a domain. The second situation involves remote management, where the user logs in to a domain.

A method and apparatus are disclosed for modifying a transition to an altered power state of an electronic device based on accelerometer output. The apparatus includes an electronic device having a display and an accelerometer. The apparatus also includes a determination module, and a modification module. The determination module determines an in-use condition of the electronic device based on accelerometer output for the electronic device. The modification module modifies a transition to an altered power state of the electronic device in response to the determination module determining the in-use condition.

An apparatus, system, and method are disclosed for securely authorizing changes to a transaction restriction. A security module securely stores encryption keys for a payment instrument. The payment instrument electronically transacts payments and includes a transaction restriction. An authentication module receives an authentication from a user of the payment instrument. The security module validates the authentication with a first encryption key. In addition, the security module authorizes a change to the transaction restriction using a second encryption key if the authentication is valid. The security module resides on a computer that the user designates as authorized to validate the authentication.

An apparatus and method are disclosed for state sharing. A change module detects a change of a configuration state for at least one of a base and a detachable device. A connection module detects a connection between the base and the detachable device. The detachable device provides a display and a network connection for the base if the base and detachable device are connected. A synchronize module synchronizes the configuration state of the detachable device with the configuration state of the base in response to detecting the connection and detecting the change of configuration state.

An apparatus and method are disclosed for power management. A monitor module monitors a connection between a base and a detachable device from the base and from the detachable device. The detachable device provides a display for the base if the detachable device and base are connected. A detection module detects a connection event selected from the group consisting of a detachable device connection to the base and a detachable device disconnection from the base.
