I am having problems coming out of standby mode. Windows XPE goes to standby
mode when I pressed the "Standby" on bezel key of my display. Windows never
responds when its in "standby".

Do you know what could be the reason ?. My BIOS has some power settings S1,
S3 and S1/S3. The current setting is S3, I also tried S1. It didn't make any
difference.

One thing I should mention is that it was working fine with XP Pro.

Thanks

SC,

Can you clarify what do you mean by "Windows never responds when its in
"standby""?
Is it NOT coming out of the Standby if you press a key on the attached
keyboard? What keyboard/mouse do you use - PS/2, USB?
 
KM,

Yeah, its not responding to the keyboard. It is PS/2.

Windows XP Embedded is installed on a display. It has bezel keys, one of the
keys is the standby. When the standby key is pressed, I send scan code via
the PS/2 link to the computer running XPE. Windows responds to my scan code
and gets into standby mode. Now the problem is waking up. It never comes out
of standby. I am not sure if I am missing any components.

SC,

What scan code you are sending down to the XPe system? IS it your code that
puts the system into the sleep? If so, can you show us that piece of your
code?

Also, you can try and test the wake-up on your platform running XPe. All you
got to do is set up a wake-up time or task and then put it into the Standby.
You can do that either by setting up a Scheduled Task and set the "Wake up
the computer to run this task" checkbox or use 3rd party tools like
WakeOnStandBy (www.dennisbabkin.com/wosb).

Also, do you use the correct (ACPI) HAL component in your image?
 
Hi KM,

I am sending keyboard scan codes, scan 2 make code = 0xE0 3F and scan 2
brake code 0x E0 F0 3F.

It is working fine with Win XP Pro, I am able to go and come out of standby.
I suspect it is related to Minlogon, I am using Minlogon and it looks like
the task scheduler is not working properly. As a quick test, I have include
Winlogon and going to test it out. I am running FBA at the moment. Is there
any way I could use Minlogon and make the standby feature work ?.

thanks
SC
 
KM,

It worked with Winlogon, do you know why Minlogon is not working ?. Is there
a patch for the standby/resume problem for Minlogon ?. Please let me know.

thanks
SC
 
KM,

I am having problems with Windows XP Embedded standby mode. Win XP Pro is
working fine. I have included all the necessary ACPI components. I am using
Winlogon. Do you know what I may be missing ?. XP Embedded worked just once
and it stopped working. XP Pro is fine all the time.

thanks
SC
