Very low power PC?

Of course that really depends on the details of your usage.

I forgot to mention windows XP includes something called
"hibernation". You probably are not always connected to the
Internet, like an Internet instant messaging program, so you could
use that I suppose.

If I were you, I might tailor my search towards achieving that end.
It is a challenge, others might have better advice (maybe in other
groups too), I gave up using power management or anything like
hibernation a long time ago (except for the monitor and hard disk
drive). You will definitely want to use the most recent operating
system.

Seems to me that otherwise you would go with a notebook PC.

Good luck.

yreah I know I can do all that

but was curious if there are some low power
components... CPU, etc.... one can use to "design in"
low power efficiency<!-- ~MESSAGE_AFTER~ -->

Curious as to why you gave it up?

Too much hassle to setup? Didn't work as expected?<!-- ~MESSAGE_AFTER~ -->

Get a Via C3 machine. I got a barebones shuttle system with a 1GHz
Nehemiah processor onboard. It has built in sound, graphics, LAN,
firewire, and USB. It's in a small Ali case, which looks amazing, and
was £130 from overclockersUK. Just had a look though, and they seem
to have stopped doing it.

The 1GHz CPU I had has a max power consumption of about 18W, whereas
other modern processors are all over 50W. They do some slower
processors which are even cooler though, and you can get them in the
mini-itx (very small) form factor. Some of these are now available on
ebuyer, but are relatively expensive becaue of their size.

The performance of these CPUs isn't like Athlons or Pentiums, but I
haven't found much difference between my 1GHz C3, and my Athlon XP
1700+. The FPU is supposed to be rubbish, and it does seem to take a
long time for compression and decompression (such as zip files). The
other cores (non-Nehemiah) have a half speed FPU which makes them even
worse. I've added a PCI Geforce 4 MX440 to my C3 machine, and it can
play Counterstrike at a high resolution with no problems. In fact it
matched my Athlon XP 1700+ with a similar graphics car, but with the
APG verion. For some strange reason the CPU usage seems to be
approxamately half on the C3, than the XP. It's only at 22% while
running Counterstrike, so Counterstrike obviously isn't CPU intensive.

I'm not sure what a PVR is. These kind of machines would be ideal for
something like a file server though. There's loads of mini-itx stuff
available at mini-itx.com<!-- ~MESSAGE_AFTER~ -->

I recently did a power-consumption test on a P-II-300mhz
and found that in idle it only drew 50 watts!
Under full cpu load it was perhaps 100 or so<!-- ~MESSAGE_AFTER~ -->

It will be spendy and choices of MBD are limited, but you can build a
Pentium-M based desktop.

Did not work as expected. Seems to me that Microsoft has had a
difficult time coordinating its operating system efforts with
mainboard maker's efforts. Others may have other experiences.

Over time the technology becomes more efficient for the same speed,
but still the higher the power the faster the system (and vice
versa).

If you don't like waiting for Windows to boot, see if hibernation
will work. I would be interested to know whether it works for you.
Maybe you can test it on your current system. Whatever, please let
us know how it goes.

Good luck.<!-- ~MESSAGE_AFTER~ -->

An adaptor just came out that allows the Pentium-M to be used in Socket 478
motherboards.

It isn't Microsoft that has the issues, its the hardware driver
writers.

THings have changed. Companies are now making motherboards which allow
you to use a Pentium M.

Absolutely. Use mobile CPUs. Use slower CPUs. Use RAM instead of a HDD.

And there's even dedicated Pentium-M mobos now appearing.
