  If the power-on indicator remains unlit after switching on your Fujitsu Desktop, it could be due to: * A faulty mains voltage supply. Check if the power cable is properly plugged into the device and a grounded mains outlet. * An overloaded internal power supply. Unplug the device, wait approximately 3 minutes, then plug it back into a grounded outlet and switch it on.

  If your Fujitsu Desktop cannot be switched off with the ON/OFF switch, it may be due to a system crash. Keep the on/off switch pressed for at least 4 seconds until the machine switches off. Be cautious, as this can lead to data loss because it doesn't allow the operating system to shut down properly, potentially causing error messages upon the next start.
