Anyone using "Hibernate" and/or "Stand by" with XPe? I am developing a
system that is supposed to go to "Stand by" many times during the day, I
have the feeling that the system will eventually fail because this feature
is unstable (just a gut feeling), any comments?



Thank you.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~Why?

If you use "stand by" or hibernate, you'd better close your virtual memory.

What makes you think so?

Hibernation (as it dumps the RAM to a file on disk) may wear out your CF card if used. But other than that why unstable?

As more toward the desktop x86 hardware, I am using Standby (and Hibernation) features all days for many times per day on my laptop
with XP Pro. I haven't noticed much unstability there except, say, after a sudden power loss in area around (no UPS) or changing
hardware why in suspend mode (not recommended anyway).
XPe is based on the same binarines as XP Pro, so the kernel is the same and supports the Standby and Hibernation features in the
same way.

Hi Sir,
Due to our system also has "can't resume from Hibernation" issue with
XPe, but XP-PRO function normally, Could you pls advise which place can find
some good debug tools?

Steven,

As you say XP Pro functioning properly on your hardware with regards to the Hibernation.
I'd first check a few places in the Configuration to make sure you've got it setup properly:

- Make sure you are using one of the ACPI HAL components ("ACPI ...PC"). You should know better which one is approprite for your
hardware but you can always check it out with Device Manager from XP Pro running on the device.
(although, if you have ACPI compliant hardware and even use Standard PC component, Hibernation should still work)

- Turn on hibernation support in your image ("Enable hibernation support" check-box on Power management Settings section of the
ACPI PC component.

- Add "Disk Dump Drivers" component (Visibility=200) to your Configuration

If all this does not work for you, you can try using Microsoft Kernel Debugger (or WinDbg) to track the problem source down. This
very powerful tool can be downloaded from here: http://www.microsoft.com/whdc/ddk/debugging.

Hi Steven,

Also you must componentize and use all fresh drivers for video card, and other third party drivers like network, audio, etc.
For beginning do not include drivers beside video and chipset drivers.

I was just checking! By the way, does any one know if the CPU speed
throttles down when the computer goes into stand by? Is that CPU specific?

Thanks.
 
Hi Rene,

Yes this feature is processor specific. But we are here talking about the processors supported by XPe right? If so then this feature
is standard.
Also processor work in throttle for all time remained for Idle process during the work.
Sleep should have even deeper impact, like processor should do some work on IRQ and then go back to sleep again.
