Can't resume from standby

[videobruce]

Running 2k; I can't resume the desktop from standby. Hibernate does work ok. According to M$ the difference between Hibernate and Standby is:

" Hibernate saves an image of your desktop with all open files and documents, and then it powers down your computer. When you turn on power, your files and documents are open on your desktop exactly as you left them. Standby reduces the power consumption of your computer by cutting power to hardware components you are not using. Standby can cut power to peripheral devices, your monitor, even your hard drive, but maintains power to your computer’s memory so you don’t lose your work."

When I hit the power button in the standby mode the box powers up, but the video card doesn't, or at least the monitor doesn't get the signal.

Any ideas?

Win2000 resume from standby (http://www.jsiinc.com/SUBF/TIP2800/rh2832.htm).

More info from the same site (http://www.jsiinc.com/SUBO/tip7300/rh7383.htm).

Also, from http://www.pctechnicians.ca, Computer Does Not Resume from Standby Mode in Windows 2000

When you attempt to resume your computer from Standby mode, the computer may not wake up.

This behavior can occur if the following two conditions both exist:
*Advanced Power Management is enabled in the Power Options tool in Control Panel.
*Your computer's BIOS is configured to suspend your computer and the time-out value is less than the value configured in the Power Options tool in Control Panel.

To resolve this issue, configure the time-out settings in the Power Options tool in Control Panel so that they are for a shorter time than the APM time-out settings in your computer's BIOS.

Hope this provides some clues, ;)

It does power up, but I assume it is hanging somewhere as there isn't any HDD activity. ACPI is set on this box.
That 3rd link doesn't work.

Sorry about the bad link.:o

APM and ACPI isn't the same thing is it?

[Kimbo]

No, I don't think so. Maybe you can make some sense out of this article:
http://www.acmqueue.com/modules.php?name=Content&pa=showpage&pid=81&page=1

Sounds like APM came first and was a precursor to ACPI. I know I have an ACPI setting in my BIOS with a default value of S1(POS) - Sleep Type Power on Suspend, but I have all suspend times and wake-up events disabled. There's also a setting there for VGA but the default OFF. No mention of APM, but I've seen that on older machines I've worked on. Something like "Resources Controlled By APM" if I remember correctly. I usually disabled everything under that setting because I'd had problems similar to yours. Systems that wouldn't "wake up" after hibernation.

My current system with Gigabyte GA-7DXE board has all suspend options disabled in BIOS Power Management section, but in XP Pro, Control Panel, Power Options, I have Hibernation enabled, and in Advanced have the following:
When I press power button - Shut down
When I press sleep button - Stand by
Both standby and hibernation work correctly, so maybe Windows can control power options independently of the BIOS.

What suspend times do you have set under ACPI in your BIOS and what times under Power Options in 2K? Did you try turning off those in BIOS?
Seems if you set those in Windows to LESS than the BIOS values they won't conflict, but also look for a VGA setting under Power Management in the BIOS. Might need to use a bit of trial and error to figure this one out. ;)

Yes, I thought that. I remember reading up on it when I made the switch over to 2k.

Here are my bios settings (Award V6):

under Advanced:
APIC Mode= enabled
MPS Version control 1.4

under Pwr Mgn:
ACPI= enabled
Suspend type= S1 & S3 the other choices are; S3(STR) & S1(Pos)
WOL from soft off= disabled
WOR from soft off= disabled


The only place I see time settings is that Suspend type which is set to the default.

[Kimbo]

What settings are you using in Windows under Power Options?

I'm using XP Pro and am not very familiar with 2K, but I believe the interfaces are somewhat similar. As weird as this may sound, these are my settings under Control Panel/Power Options:

Power Schemes
Home/Office Desk
Turn off monitor: Never
Turn off hard disks: Never
System standby: Never
System hibernates: Never

Advanced
When I press power button - Shut down
When I press sleep button - Stand by

Hibernate
enable hibernation is checked

When I want to standby or hibernate I do it manually - Start, Turn Off Computer, Standby. If I want to hibernate I do the same but hold down the Shift key when clicking Standby. Both standby and hibernate work properly and resume without problem for me, but maybe that's because I'm doing it manually instead of setting a suspend time. I don't have a Sleep button on my keyboard so I can't test it that way, but it would probably still work OK if I did.

As I mentioned, the ACPI setting in my BIOS is enabled with a default suspend value of S1(POS). Maybe you could experiment by just using the S1(POS) setting to see if that helps. I absolutely wouldn't recommend disabling ACPI as it serves other purposes than power management.

[videobruce]

I wouldn't disable ACPI. I have read elsewhere that it causes problems.
What is this S1 & S3 business??

Settings:
HDD's- 10min
Monitor- 45min
all others; never

I don't have a suspend time, just a power down for the monitor and HDD's. Other than the HDD's and monitor nothing shuts down by itself! I manually would go into standby if it would work with the app that would use it. I hate when things are left one hour after hour wasting power for no reason. I'm a firm believer in:

"When not in use, turn off the juice!"

[Kimbo]

My manual says, for what it's worth:
S1=(Power on Suspend) processor stops and remains connected to the bus, keeping the state and the content of internal registers.
S3=(Suspend to RAM) processor stops and does not keep the state and the content of internal registers.

Have you experimented with setting your HDD and monitor to never and then trying to do a manual standby?

[videobruce]

OK on the "Power on Suspend" and "Suspend to RAM"

It was set to both and I never changed it. Never used that feature before, but I will look into it. It is ON:Y because of one program that I want to 'puter to go into standby or hibernate between when the program needs to run.

BTW, so there isn't any misunderstanding, I'm talking about a Standyby from the start menu, not just waiting for it to go into Strandby by itself.

[Kimbo]

Standby from the Start menu is what I was calling a manual standby.

I re-checked my BIOS settings (Award 6.00) under Power Management:
ACPI Sleep Type - S1(POS)
Suspend Time Out (Minute)- Disabled
Soft-Off by PBTN - Instant-off
System after AC Back - Off
PME Event Wake UP - Enabled
USB, PS2, Keyboard, Modem - All Disabled
WOR/WOL (Wake On Ring, LAN) - Both Disabled
Resume by RTC Alarm - Disabled
IRQ Wakeup Events - Press Enter
VGA - OFF
LPT & COM - LPT/COM
HDD & FDD - ON
PCI master - OFF

I'm a bit confused by this. Is there a difference between suspending and powering down? What happens if you set them to never and try the Start, Standby procedure?

The app you want to work with standby may be the problem, but I can't imagine why that would be. Maybe wiser heads than mine can help figure it out if you want to tell us what that program is.

Just for clarification purposes, on my computer:
Hibernate - totally shuts my machine down. Monitor, HDDs, fans, etc. are off. To resume, I have to hit the power-on button and the PC restarts to exactly the desktop I was using before hibernation. It bypasses the Welcome Screen and all other users to automatically log me on.
Standby - turns off the monitor but fans are still powered up. I don't know if HDD is powered down or not. To resume I have to hit the Enter key on my keyboard or move my mouse. My desktop and open apps are still there, but if my dialup internet connection is active before standby, it is not maintained and I have to reconnect.

All things considered since we're using 2K and XP, I'm stumped at this point. :confused:

For Hibernate it is the same on my box.
For Standby, are you a manual Standby or letting the box do it by itself?
For me, doing it manually using the keyboard doesn't wake the box back up. I have to hit the power button.

[Kimbo]

On mine, I click Start, Turn Off Computer, Stand By. My monitor immediately goes black but I still hear my CPU and case fans spinning. I don't know if the hard drive turns off or not, but I don't see its red light flashing so I'm assuming it's not being accessed. When I want to use the box again, I just move my mouse or hit the Enter key and it wakes back up, except for modem dialup connection. You said before you're a believer in "When not in use, turn off the juice!", so I don't think this is what you want.

If I click Start, Turn Off Computer, Shift+Hibernate, I get a screen that says Preparing to Hibernate with a status bar running across, then everything completely turns off - fans, monitor, drives, just like I pulled the plug. When I want to use the box again I have to hit the Power button, but when it boots it puts me back to my desktop exactly the way it was before hibernation except for modem dialup connection. This sounds more like "turning off the juice".

I ALWAYS standby and hibernate MANUALLY using the above procedure - the box never automatically does it by itself because all my Control Panel, Power Options settings are set to NEVER.

Hope I'm explaining this clearly enough. :) I don't personally use either standby or hibernate because they are too complicated for my husband to understand - he's a MAJOR computer illiterate ;) - but I've been testing them on my box to tell you how they work on mine. I let him use his trains screensaver so he'll be happy, and when I know we won't be using the computer for many hours I just shut it down.

[videobruce]

Wait a minute.............a husband who is computer illiterate and has a Trains screensaver?
Hummmmm...........??????

(Yes, I do understand the difference, but the standby doesn't wake with a keyboard or mouse movement. I really don't need that, the hibernate is ok with me just for this app.

Well, I had to set it up for him, and you gotta admit it doesn't take much knowledge to run a screensaver -- kinda takes care of itself.:D He has 1-click email on his desktop (he can type as he used an old manual typewriter on the job for 25 years) but other than that computers are a mystery to him. Sure was easy setting up his user account!;)

Glad at least your hibernate works and wish I could have helped fix your standby, but sometimes we just have to make do with what we have.
