The following troubleshooting tables are designed for use by both trained and untrained support
personnel. They should be the first tool used to determine the symptom(s) or condition of a

crash dump and receive OS error information. This button can be used to recover a hung system,
and to obtain information useful for debugging -- it is less harsh than a power reset.
