The monitor works when
you turn on the system,
but goes blank after some
period of computer
inactivity.
The computer is probably set for energy savings
using one of the power management settings. If
the power management features are enabled,
disabling or changing the settings might solve
the problem.
If this does not correct the problem, contact IBM
technical support.
