What to do if Fujitsu CELSIUS M740 power-on indicator remains unlit?
- BBenjamin McintoshAug 4, 2025
If the power-on indicator of your Fujitsu Desktop doesn't light up, it could be due to: * A faulty mains voltage supply: Check that the power cable is properly plugged into both the device and a grounded mains outlet. * An overloaded internal power supply: Unplug the device from the mains outlet, wait approximately 3 minutes, then plug it back into a properly grounded outlet, and switch the device on.
