problem with hibernate

Feb 5, 2004 12:37AM PST

I have not used hibernate since I changed to xp and can't seem to get it to work except manually. I set the power settings to variou different ones and set the hibernate to one hour - the other settings would be shorter. Also, of course I set allow hibernate.
I also use a screen saver. Could someone explain the hibernate set up. My machine is AMD with the usual bells and whistles. Would some background programs cause this problem?

This is a tough issue you need to take up with the machine's maker. They will have to supply the machine ready to hibernate to you and just like before, it turns out that for desktops, hibernate gets broken by drivers that are rushed out the door for this simple reason.

It's a desktop and hibernate is far from a priority in desktop driver development. Can you hear the manager asking "Is it done yet?"

Just like in the past, you'll find that you may never fix it or if you do, a MS Patch or a new driver will break it again.

Take my advice, use the monitor power saving mode or ...
Complain to the maker of the system about it.

Part I.

1. In order to use the ACPI Power Management features in Windows XP, a computer must have a compatible ACPI-compliant BIOS. If the computer has an ACPI-compliant BIOS, an ACPI Hardware Abstraction Layer (HAL) is installed which allows the use of ACPI power management features. If the computer does not have an ACPI-compliant BIOS, a non-ACPI HAL is installed and ACPI power management features are not available.

2. The article [Q314088] describes the process used by Windows to enable and install Advanced Configuration and Power Interface (ACPI) functionality. An ACPI system consists of a series of 10 tables that define which devices are present on the system and what their capabilities are as to configuration and power management that are built by the system BIOS at startup. When the computer starts, the system BIOS looks for specific entries in two of these tables, 1) the Fixed ACPI Description table [FACP] and 2) the Root System Description table [RSDT] to determine whether the system is ACPI-compliant. Information is extracted from these tables in the form of an OEM ID, OEM TABLE ID, OEM REVISION and CREATOR REVISION. If these tables are not present or if the information in those four descriptors is invalid, the system is assumed not to be ACPI-compliant and the legacy hardware abstraction layer (HAL) is installed.

3. If APM was not enabled during the installation of Windows, either the computer's BIOS was on the disable APM list or it is not listed on the auto-enable APM list. Apmstat.exe (a tool included with the Windows Support Tools on the operating system CD) can be used to determine if either is the case. At the command prompt, type pmstat, and then press Enter.

a. If a reports is rendered that an APM BIOS is known to be incompatible or that an APM BIOS is known to have problems, do not attempt to force WinXP Setup to install the APM support. Doing so could cause the computer to behave erratically and even lose data. Also, if it is determined that an APM BIOS is incompatible, make sure the option for APM is disabled in the BIOS.

b. If it is reported that an APM BIOS is not known to be compatible or it is not known to be incompatible, APM might still be used but the user must enable and ensure the configuration of the APM options so that it works properly.

*Can you give more information about your machine- desktop? Notebook ?

*Hibernation needs a certain amount of free disk space to work.

*I set the power settings to variou different ones and set the hibernate to one hour - the other settings would be shorter : what others things "would be shorter" ? ...if so, hibernation at one hour would have no chance to work ?

* Did you save the settings ?

Thanks for your comments. I have lots of free disk space. I always have the monitor set for 10 mins.and I have tried various settins for standby and hard drive
- always less than the seting for hibernate. I notice that occasionally the power schemes changes on it's own from desk top to portable and I get a window telling me two revision levels are incompatable.
