My old ns01 that I have sold on stopped working after a power cut a while back. this suggests it could be the battery that keeps the settings alive that is no longer working. We tried to get into the bios settings using a usb wireless keyboard and a screen, but failed most likely because we did not have a wired keyboard. Pressing the delete key to get into bios did nbot work for the short time text was shown on the screen, and the ns01 eventually was back to where the network seems to be alive and the logo was working.
We will try again when we find a wired keyboard and hope we manage to get into the bios settings, but is there anything else we are overlooking.
