The Toughbook CF-19 is a maximum-performance notebook from Panasonic with several modern features, one of which is the ability to use the device as a writing tablet thanks to the inclusion of a touchscreen. With all of its awesome features, though, there are times when the Toughbook may experience some technical difficulties. In those situations, it is helpful to reset the computer whether through the menu or forcibly.
Open up the "Start" menu. Select "Shut Down Computer" and click "Restart." The computer should close all programs down momentarily before restarting.
Press the "Restart" button next to the power button. The computer will restart automatically.
Hold the power button for a few seconds. The computer will shut down manually. Press the power button once more to turn the computer back on. This should only be used if selecting "Restart" from the menu does not work.
