System Management Guide: Operating System and Devices
Booting a System That Crashed
In some instances, you may have to boot a
system that has stopped (crashed) without being properly shut down.
This procedure covers the basics of how to boot if your system was unable to
recover from the crash.
Prerequisites
- Your system crashed and was not properly shut down due to unusual conditions.
- Your system is turned off.
Procedure
- Ensure that all hardware and peripheral devices are properly connected.
- Turn on all of the peripheral devices.
- Watch the screen for information about automatic hardware diagnostics.
- If any hardware diagnostics tests are unsuccessful, refer to the hardware documentation.
- If all hardware diagnostics tests are successful, go to the next step.
- If your machine has a key, then change
the key position to correspond to the service mode.
- If the key was in the Normal position when the system crashed, it will reboot automatically when the power is turned on.
- If the key was in the Secure position, turn it to the Normal position. The key must be in the Normal position in order to perform a complete reboot.
Note: If your machine does not have a key, please refer to
the User Guide or documentation that came with the machine for the specific
steps for booting from removable media.
- Turn the system unit on.
