Excuse me, I can't understand exactly.
Do you means that they are independent? Are there not conflict between
them, if they are controlled separately?
If OK, the system power state transition is controlled by whom. And, What
are the trigger events?

Neither. This is separate (lower level) power management that is controlled.
by the kernel/hardware. It runs simultaneously with the functionality
provided by the Power Manager (PM.dll) component. The PM functionality
occurs only during the block labeled On, but it can trigger events that
cause transitions out of this block.

Thanks for your kindly help.
And, there is another question about the power state and transitions.
The trasition between the power state which is described in
"http://msdn2.microsoft.com/en-us/library/aa450568.aspx"; is the default
model
or PDA model? It is difficult to know what is the "real" system power
state
which I use and what is the condition of transition.
Best wishes,

This points out why it is important to mention the version that you are
using.
So look for the PXA270 display driver in Public\Common\Oak\CSP for CE 5.0

Excuse me, would you please tell me what the version of PB is?
I can't find the path in PB 5.0 .
Thank you,

Thanks for your response.
Further, the driver must implement the IO control function for
handing
the
power state changing. Is it the same for the GWES driver? Is there
any
sample
of power manager for display driver ?
Thanks a lot

The components are selected in
WINCE600\PUBLIC\CEBASE\OAK\MISC\winceos.bat
based on sysgen variables. In that file, you can see that the PM
PDA
component adds support for pda version, otherwise the default
version
is
used. So if you have PDA is selected, that should be the one you
get.
You can modify the mappings by adding entries for them in
platform.reg.
Platform.reg overrides common.reg.

I have some questions.
How do I know what kind of system power which I use, If I add two
PM
models
(Default and PDA)?
How to modify the mapping of system power state to device power
state
without
modify common.reg?
Please give me advise.
Best regards
