Booting a System That Crashed

In some instances, you might 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

1. Your system crashed and was not properly shut down due to unusual conditions.
2. Your system is turned off.

Procedure

1. Ensure that all hardware and peripheral devices are correctly connected.
2. Turn on all of the peripheral devices.
3. 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.
4. 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 reboots 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 see to the User Guide or documentation that came with the machine for the specific steps to boot from removable media.

5. Turn the system unit on.
