Re: Fast Start-up

You need to be or know well the device vendor to know what is possible with
respect to power management. Trying to do something good without knowing is
likely to be a big waste of time. Pocket PC devices, even phones, which are
essentially never off, have battery lives measured in days with relatively
small batteries. You need to decide on a specification for how long the
device is going to live; that will guide you when you decide what happens
when you "hibernate".

You can improve boot speed, but it's still going to be seconds, not
milliseconds.

I need to be very careful with the power consumption, and therfore need to
power down the processor and peripherals. So I'm guessing I need to either
use a power down and re-boot or some kind of hibernate? In addittion I
have
had some previous bad experiences with things such as bluetooth drivers
restarting, and thought a full boot might be safer option.

I have access to platform builder and have made small changes before. I
have
read somewhere that faster full boot times should be possible.

You haven't told us anything that would help us there. The "shutdown"

mean anything. It might be suspended, like what a Pocket PC does after a
few minutes. When you press the power button, it's back on very quickly,
as
the RAM was maintained, etc. and the processor simply has to be started
up
where it stopped. It might literally be off, though, in which case,
you're
doing a full boot of Windows CE and 7 seconds is fantastic. If this is
not
a device that you build, there's nothing you can do from an application
program to change the power-down states provided by the device.

I'm a releative newbie on wince so sorry if this is obvious.

I have a low power mobile application which requires the O/S to
shutdown
and
then a later time restart quickly. Does anyone have any suggestions on
how
I
can improve my start-up time (typically about 7 seconds at the moment).

Thanks.
