Question for Computer Hardware gurus

[N_Jay]

WHY (Oh Why) do I lose the ability to use Hibernate mode when I put a PCI video card in for a second monitor.

System is a intel 810 chipset MB running XP using the Intel graphics on-board and a pci VGA card.

I can't imagine, because I can't imagine a new video card not having support for most power modes. But personally, I wouldn't use hybernate on anything but a laptop. What about standby? Does that work?

They are old cards.

About when did hibernate come into common use?

What is wrong withg hibernate, I hate standby. I have never had good luck with stability before, but I may try it.

just a shot, but the Hybernate file that is created is a snap of the profile of your sytem at the time you selected it. Have you tried to uncheck the hybernate mode, reboot so it gets wiped off and then select it again? My guess is that its detected that your HAL or other has changed and now wont allow you to use it. I would think this will do the trick. easy enough to try.

This does have SP 2 I presume?

Is the problem that the PC does not enter the hibernation state or that the option is not available on shutdown? If it is the latter, is the Standby option available?

It may be the the PCI video card is not ACPI compliant, or you are running it with standard VGA drivers. If the card does support ACPI, then try downloading the latest drivers if you can find it.

One recommendation might be to disable the onboard video and upgrade to a duel head AGP card (I assume your motherboard is not PCI-express).

I will have to try the new drivers.

Windows did not ask for drivers so I assumed it had current ones.

The Hibernate option does not even show up (nor does standby)

Try this, I think ictvuser is on the right track,in that its driver related.

The power management code on PC's is a horrow show. It's pretty amazing that anything works at all. A given vendor can tweak things to get it to work on a fixed laptop hardware configuration, but when you start swapping boards around all bets are off. I wouldn't go too crazy trying to fix it.

Standby:
Mainly for power savings. For hardware that supports it, power is retained but in a low-power mode. The monitor shuts down video circuitry, disk drives spin down, heat is reduced, fans turn off, etc, all gradually in accordance with the control panel settings. But running programs are kept in memory and the chipset keeps most processes and services running. I haven't shut down or rebooted any of my desktops in months, I just let them go into standby if not touched for a while. (But I do close all programs.) Most PCs will draw about 25-35 watts in standby.

Hibernate:
Completely powers down the computer, but moves everything in memory to disk and stores all running programs, processes, services, and states. When powered back up, all previous states are restored. Not very graceful or reliable. Some programs and hardware don't support it properly. Not intended for power savings. Mainly intended for laptops; e.g., you're working on something and you want to show it to someone in their office at the other end of the building and you don't want to walk through the hall with the screen opened up; or you're doing a presentation and you want to have all your programs and "stuff" ready before you hook up to the projector; or you're working on something in the airport, and you have to board the plane; or the most common reason: you have to swap out the battery.

Anyways, that's how I see it.

I have a little different take.

Standby: Basically the PC stops where it is, all hardware must be capable of soring and maintaining current information while in this state or the machine is likely to come up without access to certain functions.
VERY unreliable unless the whole system is carefully designed for it.
USB stays powered so USB accessories stay on (external drives keep spinning)
Also comes out with a bump of the mouse (very annoying)

Hibernate: Current configuration and all memory information is written into a file on the hard disk and the PC is shut off with a note in the MBR to boot from the memory image.

Seems to work well except for a very few issues.
Had one USB board that did not like to wake up (bad drivers I think)
Is (supposed to be) disabled if the configuration does not allow it (what is happening with old VGA cards).
