What, do you really think that an Efika will consume *more* power than the standard high power x86 laptop motherboards/CPU's we see today?
Well, Intel mobile machines CPUs could reduce power consumptions during moments in which is not required heavy stress usage.
I don't know if MPC5200B could perform the same.
It seems to me that next to come MPC 8641 CPU could do that such as Itel CPUs.
Then take a look at consumes:
MPC 5200B consumes standard 2 watts/hour at quite normal usage.
It has been stated into Efika II thread that graphical card XGI consumes 10 watt/hour at normal 2D usage (it consumes more when 3D is active and running).
So we must now discover how much do consume these components:
1) LCD LVDS screen
2) hard disk
3) CD-RW or DVD-RW ultraslim device
4) Human interface devices (keyboard and mouse)
Then we must made the sum of standard power consumes for all these devices tied together.
Think also we must realize a good power and maintenance software to activate their power-off features after a certain amount of inactivity...
(realize the software if Efika could had MorpHOS running on it, and adjust fine Linux power saving features, when linux is used on Efika as main OS)
Then (and only then) we will discover what model of battery for laptop use is suitable to build our Efika Laptop.
I made just some calculation in my mind and I think IMHO that 1 or 2 (at least) 2700 mAh laptop power batteries could perform the task of giving us a good price/time/weight of the laptop/performance ratio, with Efika running for 1 or 2 hours of continuous work without plugging the power cable.
I hope some technician of your level could calculate better than me the power we need to create a good Pegasos-Efika laptop.
If 2700 mAh are not enough, then on the market are available also 3600 and 4000 mAh (and more?) batteries models, but then the weight of the laptop will grow up noteworthy.
