locking up the system.

Your system has
crashed.
Try to restart your LifeBook notebook. If that fails, turn off the
power using the power/suspend/resume button, wait at least 10
seconds, and then power on. If turning off power with the
power/suspend/resume button fails, the button has likely been set
to suspend or hibernate. In that case, disconnect the power cord,
then remove and re-insert the battery.
