Standard PC and Standby

[AK]

Hi,

My devices.pmq shows the system as StandardPC and so the StandardPC
component gets added when I resolve the dependency. But I need standby
option.

I checked by bios and its power option says that ACPI is enabled.

When I forcefully included ACPI component removing StandardPC the fba
has shown blue screen.

Is it possible to have standby with StandardPC (because hibernate is
there) or include ACPI somehow?

Thanks
AK

Is normal XP supports Standby on that hardware??

Hi Nikolai,

I can't install normal xp on that hardware as there are some display
issues also.

AK,

You can try and use WinPE on the target (if CD-ROM option is available to you there). From there you can launch xpepm ("Power
Management Application" from XPe, just put it on hard disk) to see what's supported.

If "hibernate" option is available to you in your XPe image, then StandBy should also be there. "Hibernate", internally, does the
"standby" first.
Try xpepm -standby (or fbe.exe -standby) command to see if it works.

Btw, it is weird that On ACPI enabled MB you can only use Standard PC. Do you know if the MB manufacturer tested it under XP Pro?

Hi KM

I tried xpepm -standby command and it gives an error

that Error 1141- The system bios failed an attempt to change the system
power state.

The hiberate happens properly but when I start the system again then
sometimes I see freeze with wiered colors and sometimes I see blue
screen with message that icegmini driver has gone to infinite loop.
This is the display driver provided by intel. So it means that this
driver has problems. Isn't it?

AK,

That sounds a bit strange but a few things for you to check:
- Go to Device Manager and check if all the drivers are installed and functioning properly.
- Check whether all the drivers in your system support S1/S2/S3 mode.
- Instead of xpepm or etc., test the system with calls to SetSystemPowerState() API.
- Make a simple app that will call to GetPwrCapabilities(SYSTEM_POWER_CAPABILITIES) and see if your system supports S1, S2, or
S3 states.
- Try using powercfg.exe (SP2) application to test your system functionality (power management).
- Make sure you enabled hibernation (either in TD on the HAL (PC) component's settings page or at run time using power meter
cpl).
- Make sure the hiberfil.sys file is created on your boot partition.
- Check out FBALog.txt and SetupApi.log for any power management install errors.

Hi KM,

I ran powercfg.exe on my system and it says that only hibernation is
supported. S1, S2 and S3 are not supported.

Although in BIOS setup I saw options as
ACPI (debug only) YES
Power Settings Customized.

I listed the drivers using powercfg.exe. Most of the drivers support
S3. But there are devices like ntfs where Device Power capabilities is
not shown.

hibernation file is present in the drive which I am using for boot.
