Standby mode / restart problem

When using the "Standby button" to shut down the PC, it shuts down as expected. When hitting any key to "resume" the power supply wakes and the cpu fan powers to full speed. (Normally when booting or resuming the bios adjusts cpu fan voltage to less than full speed). My monitor remains in a powered down state... (no signal from the computer to awake it). Only hitting the computer "reset switch" will restart the PC, which than starts as normal by "booting" and loading to WindowsXP Pro SP-2.

This problem happened about the same time I ran some maintenance programs. (Standby worked as expected before performing maintenance) I ran Easy Cleaner, Ad-Aware, Spybot, and CCleaner. All programs are the "free for home use versions ", all are up to date and have been used without problems for years. Windows automatic updates is also enabled. There are no other problems and the computer operates as expected.

Seeing that I just performed some maintenance, my guess is one of the programs might have had something to do with this problem. The cpu fan speed is my only clue in troubleshooting this problem. Anybody got any suggestions?
thanks,

Run SFC and be prepared to furnish your XP installation CD. If that doesn't fix you up, you'll likely need to do a Repair Install.

Then you'd be one of the lucky ones. CrapCleaner has hosed more systems than it ever fixed. It has the potential of doing great harm to an otherwise healthy system and the early version provides no backup. Unless you are an expert, let this tool alone. The new version is somewhat safer but still risky. I only resort to it when I have a very specific problem that I know it can attack and I have a sufficient backup.

If you have the latest version, try reversing the Registry changes you made by running the backup .reg files. That applies to CCleaner and EasyCleaner both. You might get lucky!

 

While I do not advocate using any automated utility to clean the registry, or files, it is likely that Easy Cleaner and CCleaner are guiltless for your issue, whatever surferdude2's feelings might be about CCleaner.

I note you are up-to-date with both programs. There are no known Standby issues with either program.

Running SFC is unnecessary; neither program would be permitted to remove a System File under XP, and SFC does not do registry repairs.

Your issue sounds exactly like a hung USB device. This is very common. In Windows XP, the USB core stack supports the Selective Suspend functionality. A driver can use this functionality to turn off the USB device that it controls when the device becomes idle, even when the computer remains in a fully operational power state (S0). For example, a driver can make the following devices idle: the host controller, empty the USB hubs (including the root hub), and the full range of USB devices that are supported by the operating system. The selective suspend functionality is primarily intended to conserve battery power in portable computers. USB controllers frequently use lots of battery power, even when no devices are attached to the computer.

The issue becomes when the driver fails to wake the device from S3 (Standby) to S0 (its fully operational state).

Repair efforts:

. Force a rebuild of the USB Hub entries:
Start, Run, devmgmt.msc
Expand the USB controller and hubs section near the bottom.
Right click and uninstall the Hub entries.

. Now unplug any unneeded USB device. Printer, modem, router, anything that is not necessary.

. Reboot and test.

If that works, add the USB devices you removed one at a time and retry the Standby/Wake-up sequence again to identify the device that has a problematic driver.

Second area of diagnosis:

Look to your BIOS settings. If there are settings for "legacy" or USB 1.1 settings, consider disabling them. If there are settings for USB 2.0 support, be certain they are enabled.

Relatedly, go back into Device Manager and again expand the USB Controllers and Hubs section. Double-click each USB Root Hub. Click Power Management. Uncheck the box "Allow the computer to turn off this device to save power."

Third area of diagnosis:

MS-MVP Kelly Theriot has an excellent article discussing all the ways in which a Resume/Standby sequence can be confounded by device drivers, BIOS issues and hardware: http://www.kellys-korner-xp.com/xp_standby.htm

Fourth area of diagnosis:

Make sure you have enough disk space.

 

Thanks Surferdude2 & Bill for the replys,

I first tried Surferdude2 suggestion by running SFC. I ran it two times, first with the original Windows xp disk, than with a slipstream disk with SP2 on it. No joy either time.

Haven't tried the "rebuild" or "backup .reg files" yet. This problem happened a while back. Need to check what happens when doing a "rebuild ".

Next I did what Bill suggested..


I did all of first two areas of diagnosis.. No joy...

As a follow thru I removed all usb hubs in Device Manager & all usb devices attached to computer. Still no joy.

Didn't think to disable all usb support from computer vie the bios. I'll try that tomorrow.

I viewed the link you mentioned and I'm still digesting the info.

As far as free disk space ... I have 109gbs free...

thanks

If there is a BIOS conflict it will be from legacy 1.1 support being enabled. This is the one to disable.

If there is a 2.0 setting it should be enabled.

Also, any new firewall, CD burner software, cache memory booster or anything similar installed recently?

 

I did disable the legacy usb support and enable the usb 2.0 Controller. Computer still would not resume from standby.

I think Zone Alarm is a new version and I did install Nero 7 after the problem started. Also might have installed a older fax modem pci card around the same time. I earlier did remove the pci modem but the problem still remained.

 

If you do a clean boot, does it act normally on Standby/Restart?

I did a "Clean Boot "and the problem remains... Than I probably errored and uninstalled the USB Controller in the BIOS. I have no usb devices attached to the computer so i figured no problem.. well now I can't get past post.. error message saying something the the effect USB Overcurrent.. shutting down in 15 seconds. You would think that there would be a warning message in the BIOS if disableing the USB Controller was going to be a problem.. I emailed ASUS for there input.. if I get antsi I might try resettng the BIOS..

 

If the error came from the BIOS, it should still allow you to enter BIOS setup and check that USB 2.0 support is enabled, and that the controller can be enabled.

I did not want to remove the controller entries in XP as increasingly laptops are using USB hard drives.

If the errror comes from XP at startup you can ignore it, it will not prevent a boot.

 

I tried to enter bios to enable the USB Controller but either way I get the error message and the computer shuts down.

I Can't get to a BIOS window before the system shuts down, so have to figure out the fix before that stage. I think I need to reset the CMOS/Bios.

 

Go for it.

What concerns me is if you really have a USB port shorting to ground. This is a hardware issue that removing the controller entry in the BIOS has no effect on. Re-enabling should not effect it either, unless in the BIOS support for the device the error messaging is supressed.

 

I too would expect to be able to return to the Bios setup. That not being the case.. I think I'll wait a day or two for ASUS to respond the my trouble report before trying to reset the cmos/bios. As to the hardware issue, I have had no problems with the USB ports when I did use them, and the computer operates as expected during everyday use. (up until I removed the USB Controller trying to trouble shoot the standby issue).

 

Well ASUS got back to me and what a joke.. there answer was so off base. Its was obvious that that a real person didn't view the question I asked them. Probably some database scanned the question and spit out some default answers. That taking outsourcing to the extreme...

Anyhow I removed motherboard battery and changed jumpers to reset the Cmos/Bios to defaulted setting and computer works as before. While I had the guts exposed I removed all non needed cards / drives/ and cables. Than tried to shut down by use the "Standby" mode.... No Joy...

Guess I'll just keep using the "Turn off button "... to quit for the day.

I do need to correct my stated actions in my last attemt at troubleshooting. I errored about what I turned off in the bios. I turned off the (USB Support) not the (USB Controller). Thats what triggered the error message... "USB overcurrent shutting down in 15 seconds ". (No USB devices were attached to the computer at the time).

Thanks for all the help with this issue.
