  If the power indicator on your Fujitsu Desktop remains off after switching it on, there might be a problem with the power supply. First, ensure the power cable is correctly plugged into both the device and a grounded mains outlet, and that the main switch at the rear is set to the "I" position. If this doesn't work, the internal power supply might be overloaded. Unplug the device, wait about 3 minutes, then plug it back into a grounded outlet and switch it on again.

  If your Fujitsu Desktop cannot be switched off using the On/Off switch, it might be due to a system crash. Press and hold the On/Off switch for at least 4 seconds until the device turns off. Be aware that this could lead to data loss, as the operating system isn't shut down properly.
