Waking up a Pocket PC from a complete shutdown

I have a HP iPAQ which shut itself down if the battery temperature exceeds
certain level. Is there any way (Programmatic or manual) to start it up
again?

I have already tried setting up Alarm and CeAppRunAtTime API and they
doesn't seem to work as it is a complete shutdown.

Is there are any other alternatives?
 
If there is a thermal cut-out (which I doubt), it is located in the battery.
Usually these batteries have a internal fuse only.

There is an automatic shut-down if the unit is not used. The time is set
under Settings/Power. There is also a low voltage cut-off built into the
PPC. If your battery seems to be getting too hot, you may be running too
many features. Do you use both CF and SD? Are you running WiFi or BT also?
The screen is the biggest energy hog. Turn your brightness down. I usually
run my X51V at the second click from the bottom. It is also possible that
you have an intermittant connection at the battery or inside the unit that
is making it quit when the battery gets hot. A larger capacity battery will
run cooler all the time.

Good luck!
 
Thanks for your response.

While your suggestions are useful to conserve the battery life and reduce
the heat, my real question, if the Pocket PC goes in to the shutdown mode
how to start it again?

i recently "let" my Ipaq run out of all battery power, and for a while
it seemed completely dead. after letting it sit in it's AC powered
cradle for a couple of hours, it finally woke up, and started charging
the battery.

There's not really an answer, since we don't know what state the device is
actually in (and it might vary from one to another). If it's 'off', no,
there's no code running at all, so there's nothing that you can do from an
executing program to reawaken it. You might be able to set a time-based
alarm, CeRunAppAtEvent() or CeRunAppAtTime(), which would power the device
up, but, again, that depends on what the power state actually is.

The only real way to know the answer is to either a) ask the guys who built
the hardware or, b) try it.
