The Coma mode entered by ON-SPC is a wonderful way to save batteries,
as you can see in the table below.

Here are reported some measure that me and Roberto Taddei made with a 
48 and an analog multimeter :-(

+----------------------------------------+
| HP48 & HP28 POWER CONSUMPTION IN uAMPS |
+----------------------------------------+
|         STATE        |  HP48  |  HP28  |
+----------------------+--------+--------+
|Coma mode  (ON-SPC)   |    2.0 |  106.2 |
|Off                   |   16.0 |   13.5 |
|On/idle               | 4200.0 |  446.0 |
|On/running            | 6500.0 | 2412.0 |
|On/running using FAST | 5100.0 | ------ | [See FAST on this disk. -jkh-]
+----------------------+--------+--------+

The power consumption of the HP28 is the one measured by Bob Peraino 
with a digital multimeter (easy to notice :-( 

As you can see the coma mode this time works, and it works pretty good. 
You will also notice that FAST not only increase the speed of the HP48 
but also let you save 900 uAMPS.

ciao
