dangerous. If the system does not reboot automatically, reboot the system manually as
described in Section B.6.7 (page 217).
• If the system stops responding to your commands (that is, if the system hangs), there is a
possible failure in a system software or hardware component or a possible power failure.
• If the system exhibits erratic behavior (it does not respond according to specifications), it
indicates a possible failure in a system software or hardware component.
To determine whether the failure is a system problem:
• Be sure that you did not press F1 (Hold Screen). The Hold Screen light turns on when you
press either F1 or Ctrl/S.
• Press Ctrl/T to check the status of your process. A status line should appear indicating the
name of the program that is executing and other information. If the status line does not
appear, the program you are executing might be stalled or hanging. (If you have disabled
Ctrl/T by entering the command SET NOCONTROL=T, or if you have set the terminal to
NOBROADCAST mode by entering the command SET TERMINAL/NOBROADCAST, this
procedure does not work.)
• Make sure the cable connecting the terminal or monitor to the system is secure.
If you determine that you have a system problem, take the following steps:
1. Force an exit from a stalled or hanging program by pressing Ctrl/Y. Pressing Ctrl/Y causes
any work performed by the program and not saved on disk to be lost.
2. If the system is still unresponsive, halt it (see Section B.7.1 (page 223) for more information.)
3. Note in detail the sequence of events that caused the problem and notify HP Customer
Support.
