hibernate function (WXP)

[holdenontoit]

could anyone please tell me how to restore the option to make my computer hibernate,either automatically or manually.I swear that when I first installed this O/S this function was active,but now it is no longer highlighted(active)

It took me a few minutes to remember where that control is buried. /images/forums/icons/laugh.gif

Here's the path: Display Properties > Screen Saver > Power > Hibernate tab -

all good except there is no hibernate tab.any further suggestions?

Make sure ACPI is enabled. But may I make a suggestion? Hibernation & Standby use resources unnecessarily and are hard on your system. I'd suggest just setting your display & HD to power down after a defined period of inactivity. Much easier on your system and it accomplishes the same resutls.

Holdenontoit,

To learn more about ACPI and Windows XP, go to TheElderGeek - Clean Install Windows XP.</font color=red> (http://www.theeldergeek.com/clean_installation_of_windows_xp.htm><font) Scroll down to the large rectangle called "The Role of the F5 Key and Shutdown Problems" about half way down the page. He gives a good explanation of ACPI in Windows XP.

In addition, he tells you how to recognize if your installation of XP has enabled ACPI. Here is what he says:
<font color=blue>"As a final note, to determine if your computer was detected as being ACPI enabled:
Right click My Computer then click Properties &gt; Hardware &gt; Device Manager.
Expand the entry called Computer.
If the entry is 'Advanced Configuration and Power Interface (ACPI) PC' you're all set. If it says 'Standard PC' the computer BIOS was not detected as being ACPI capable."</font color=blue>

Hope that helps,

from technet Q255182

On a laptop or desktop computer that supports either Advanced Power Management
(APM) or Advanced Configuration and Power Interface (ACPI), there may be no
Hibernate tab in the Power Options tool in Control Panel.

Windows 2000 makes its Hibernate feature available as part of the hardware
abstraction layer (HAL); the feature is independent of APM or ACPI. Windows 2000
does not support OEM BIOS hibernation.

The following issues can prevent the Hibernate feature from being available:

A device driver or incompatible software is interfering with this feature. For
additional information, see the following article in the Microsoft Knowledge
Base:

Q211271 Cannot Hibernate Windows 2000 After Uninstalling McAfee 3.1.4

For additional troubleshooting of the Hibernate feature, see the following
article in the Microsoft Knowledge Base:

Q197477 The System Cannot Go to Standby Mode Because the...

If you enable Physical Address Extensions in the Boot.ini file with the /pae
command-line switch, the Hibernate feature is not available.

from q308535

Hibernation Requirements

Computer must support APM 1.2, or ACPI.
A paging device that supports D3 (note - certain SCSI configurations do not
support this).
WDM audio.
No legacy capture devices connected.
WebTV for Windows is not installed.
Non-ICS Host (client is OK).


from me....in the power options under the apm tab the help dialogue for that
option says it must be enabled to allow for hibernation.
from me...for the os to manage power the bios must be set for apm or off/none.

from me and from experience....very important...changing and bios power options
and pc status of acpi or not, can lead to big problems. doesn't have to and
it might be easily sorted....but it might not! so, before going down such a
path i would be double sure of your actions and read some official msoft tech
on it first !!!

While disabling ACPI on an XP system can lead to problelms, XP expects ACPI to be enabled so it can force IRQ sharing - in other words, XP usually works best with ACPI (and APM) enabled.

acpi does give irq sharing, but, unfortunately it does not allow you to over-ride it and assign a unique irq to say a soundcard if you want to. for a pc used for making music, this is a big disadvantage and reduces performance/stability, and the specialist advice is to avoid acpi and prevent the sharing of the audio device irq.
as to the supported direction of change, microsoft advice from q309283 is...

With Microsoft Windows 2000, the change from an Advanced Programmable Interrupt
Controller (APIC) UniProcessor (UP) to Multi Processor (MP) on both Advanced
Configuration Power Interface (ACPI) and non-ACPI computers is supported. You
can go the other way (MP to UP) by using the UNIPROC package that is located in
the i386\UNIPROC folder on the Windows 2000 CD-ROM. You can also go from APIC to
a PIC HAL for both ACPI and non-ACPI computers, and going from ACPI to a
non-ACPI HAL should work.

The change from non-ACPI to ACPI by changing drivers is not supported. To
properly make this change, an in-place upgrade (where the computer is converted
to ACPI during Setup) is mandatory.

so i stand by my earlier advice.....having personally come a cropper going from non-acpi to acpi.
