(2) The processing speed of the equipment is slow.
Possible cause
The capacity of the memory or the HDDs or SSDs is not sufficient.
(3) The equipment is unresponsive.
Possible cause
There is an error in the hardware or software.
Forcibly terminating the equipment
If a shutdown fails, press the power switch for at least four seconds. The power turns off and the equipment goes
into standby mode.
1. Close any unnecessary applications to increase the available memory.
To check the CPU and memory usage, follow the instructions in 9.5 Checking the System Load by Using
Performance Monitor.
2. Delete any unnecessary files to increase free space on the HDDs or SSDs.
Action
1. The screen can appear to be frozen when an application freezes. If the equipment responds when you press
Alt+Tab or Ctrl+Alt+Delete, try performing the following procedure:
i) Switch applications by pressing Alt+Tab, and identify which application is frozen.
ii) After you identify the frozen application, use Task Manager to terminate the application. To open Task
Manager, press Ctrl+Alt+Delete. The Windows Security window opens. Click Task Manager.
iii) Restart the equipment.
2. Press the NMI switch to collect a memory dump. If you want to have an analysis performed on the memory
dump (a service provided for a fee), restart the equipment and save the log (see 8.4 Maintenance Operation
Commands), and then contact one of our sales representatives. If the restart is not performed automatically, turn
off the power of the equipment by referring to the following section Forcibly terminating the equipment.
3. If you are unable to collect a memory dump after following the instructions in step 2, turn off the power of the
equipment by referring to the following section Forcibly terminating the equipment.
4. If performing the actions described in steps 1 and 2 does not resolve the symptom, turn off the power, remove all
USB devices and extension boards except for the keyboard and mouse, and then start the equipment.
