Do you mean the computer's power supply? But it is supposed to run on 220-230V not on 202V!

I thought that issuing upscmd -u admin -p password mustek reset.input.minmax might make the UPS "re-think" if it should trim the output voltage, but I seems I was wrong. It does nothing. I will certainly complain to Mustek, as they say 220-230V output. > > Best regards, Arjen Thanks again, Pedro. > -- > Eindhoven - The Netherlands > Key fingerprint - 66 4E 03 2C 9D B5 CB 9B 7A FE 7E C1 EE 88 BC 57 > _______________________________________________ Nut-upsuser mailing list [email protected] http://lists.alioth.debian.org/mailman/listinfo/nut-upsuser
