Cheers!

I am curious as to how much power the HP50G consumes. Has anyone out
there have measured this? I found the following interesting numbers
for the HP48, measured by Douglas R. Cannon back in 1991:

2.22 mA at idle
7.0 mA for "normal" program execution

Should I expect similar numbers for the ARM in the '50? I am
especially interested in the relative consumption for idle and
executing(*). As the ARM is actually emulating a Saturn CPU, perhaps
it is executing all the time, regardless of state?

Per.

*) I use my '50 for playing Reversi sometimes, and the HP is in idle
state when I am thinking and vice versa.

You should take a look at this thread:

Also Erick Rechlin has measure it !

Thanks! I ought to feel bad about this, but I *did* search the group!
For some obscure reason Google Groups does not find this thread, even
when fed with the string "HP graphing calculator power consumption",
without the quotes.

Per.

It does find it from here with "HP graphing calculator power
consumption".
