Yes, Stand-by. > I thought the standby voltage is usually 5V, isn't it? You're right that the ATX standard only defines 5VSB and not 3VSB. But as many chips are powered by 3.3V these days an no longer 5V, 5VSB can be scaled down to 3VSB on the board. > > Setting in8_min to 3 V seems a bit optimistic, it's a 3 V battery > > so it could easily go slightly below 3 V. 3 * 0.95 would seem more > > reasonable.

So a max of 3.3 * 1.05 seems reasonable. > Actual reading here: 3.33V. But normally I agree, yes. As I understand it, on many recent boards the battery is backed up by +3.3V or 3VSB as long as the PSU is on / connected. This avoids killing the battery too fast. So when monitoring, the machine is up and you'll see a reading close to 3.3 V. But when the machine is sleeping, it may switch to the actual battery again and you'll get a reading close to 3.0 V. So it's better to be safe and go with permissive limits. > > For the wiki, we don't put ignore statements for inputs which do > > exist on the board (although I understand you put them in your > > local copy of the file.) > Ok. > > >> #label CPUTIN "CPU temperature" > > I suppose you really mean temp2.
