From: perstromgren on 25 Jan 2008 08:02 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.

From: DueƱo de Monte on 25 Jan 2008 08:20 You should take a look at this thread: http://groups.google.co.cr/group/comp.sys.hp48/browse_frm/thread/51b3008e10a7ead1/7c5b1c6817c4ab07?hl=es&lnk=gst&q=HP50+energy+consumption#7c5b1c6817c4ab07 Also Erick Rechlin has measure it ! Daniel

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".
