Abstract
A computer configured to operate in diagnostic mode during which the operating system is suspended. During the diagnostic mode, tests can be performed on the computer system, including hardware, and the tests do not disrupt the operating system and are not disrupted by the operating system. When diagnostic mode is triggered, execution of the operating system is suspended. When the diagnostic tests are completed, the operating system may resume operation and test data may be made available within the operating system environment. Upon resuming, the state of the computer prior to entering diagnostic mode may be restored, preventing any changes made during diagnostic mode from interfering with operation of the operating system or application components.
