So, I checked on the G-SAFE today after a short trip away, and there were no lights and no fan. At first I though I’d either turned it off or unplugged it from the mains. Neither was the case. I’ve tried a different power cable and different outlet. Still no luck. Is it dead for good, or is there some kind of internal fuse, perhaps, that I could change and see if that would solve the problem?
There is an internal power supply on the G-SAFE, so trying a new cable is the extent of troubleshooting. If there is still no power it is likely that the internal power supply burnt out.
I’ve cracked open the G_SAFE and saw that the fuse is blown. I’ve ordered a pack of replacements on ebay, so that will hopefully bring it back to life.
