Win 7 - Computer goes into sleep mode after MS updates.....

[kenmo]

After some recent MS updates (Windows 7 Home Premium 32 bit) my computer goes into sleep mode over night. I do have every thing set to NEVER in Power Options but it still goes to sleep and will not respond to the keyboard or mouse or the case's power button to wake it up. I must use the power supplies on/off button....then upon bootup I'm informed Windows did not shut down properly....

The keyboard, mouse & monitor are shared with my other Windows 7 64 bit computer via a KVM...

I did re-install an early image of my computer (via Acronis Tru-Image) & everything was fine until Windows update (I'll be turning this off)....

Running powercfg -lastwake at a terminal window does not report anything....

Thoughts?

TIA
PS: I have 4 computers in total. One Win 7 32 bit, two Win 7 64 bit and one Mandriva/Linux 2009...

My other two Win7 computers were not affected by the updates..

Check the BIOS settings on the problem computer.

I've turned off MS updates on a couple of W7 computers when they screwed things up. Probably best to turn updates off for a while so you aren't MS's beta tester. And read the update info before installing.

Anyway, in BIOS, check the computer power settings. The 'Green' mania has affected MS also and sometimes their zeal to lower power usage results in usability problems. I would also check the MB manufacturer for updated BIOS and drivers. Not necessarily recommended to update BIOS, or MB drivers, but check to see what's available that may address the problem.

Computer is still goint into hibernate mode even though I've disabled it in Windows... I could not see any power saving mode option in bios.... The computer is plugged into a APC brick style UPS (ES500) and the UPS log shows no problems...

I can find nothing in event viewer why the system halted but there is an entry that the system was restarted after not shutting down properly....

All prior updates were re-installed and the system has been stable until today...

I opened the case and reset the memory. But the fan on the video card was not working. Staples had a Nvidia 210 PCI-E card on sale so I picked one up...
I also blew the dust bunnies out...

Bios does not report an heat issues. Temp is around 98F...

Any other ideas?

PS: I also ran a check via

powercfg -energy -output c:\log.txt

At the command prompt after the command finished there was a tally claiming there were 9 errors, 2 warnings & 13 informationa... while I was viewing the log file the computer went into hibernate mode...

Viewing the log file nothing really stood out... other then USB Suspend: USB Device not Entering Suspend


When I rebooted I did go back into bios and change an energy save optin from S3 to S1...

Power saving option function is set when your video driver is active, having KVM and if you start your computer when KVM switch is on the other computer may not sense your monitor and video card may not become active. Some KVM's have buffer and this doesn't happen. The way you explained it this my best guess, try starting the computer fully connected to keyboard, mouse and monitor then check power savings if you have all the options then it is OK. Sometimes computer reboots after update maybe it did when KVM was on the other computer.

Now this is weird.... I power the system backup booting off of the Arconis boot cd to restore an earlier, unpatched image of Win7.0 on the computer and the computer went into hibernate mode will I was attempting to restore the old image...

I do have an Antec power supply test and I unplugged everything from my OCZ 550 powersupply. The power supply checked to be fine with all geen lights....

I think I may have to repaste the cpu & heat sink....

That seems to indicate a hardware or BIOS problem. Not necessarily overheat, so I wouldn't repaste the CPU just yet. Could be the PS still, but I would put it down a ways on the possibility list.

I would also try running Memtest86 from a CD drive. Bad RAM can cause all sorts of odd problems.

Next, you might pull your BIOS battery for a few minutes with the power unplugged and reset the BIOS as maybe it's corrupted. Mark down your settings first, so you can restore them.

If no improvement, I would then disconnect all drives except boot and remove all cards except the video card and try again. Since you replaced the video card, it's not likely.

If all that fails, and booting from a CD disk has the same problem, then you have the motherboard and the PS left. As a last effort, substitute the PS. PS testers don't always throughly test a PS under the proper load for each rail. I use a substitue PS instead.

At that point, unless you can find some other cause on the internet, I would suspect the MB.

But hopefully, it is something simpler.

Thanks for the response.... I knew faulty hardware would shut a computer down, just surprised it would put it into hibernate mood.... The only way I can turn it back on is to either unplug/re-plug in the power supply cord or use the power supplies rocker switch....

[kenmo]

Downloaded iso for Memtest86 v4.10. I have 2gb of ddr memory in my AMD X2 4200 computer. I did one pass of Memtest86 and no errors were found, now doing a second pass....

[kenmo]

I left Memtest to run on my computer overnight and it still hasn't found any memory errors.. It's had 13 passes.....

[redwudz]

It looks like you have eliminated memory as the problem. Unfortunately, finding the source of these types of errors usually requires the process of elimination. I was having problems with overclocking one of my PCs and Memtest crashed within a few seconds into the run. I did have bad RAM.

About all I can suggest is to try to eliminate other possible causes till you narrow it down.

[kenmo]

Could an internal hard drive or burner cause this type of problem or even an external usb device (drive or burner)...???

Thanks kindly...

[redwudz]

Not likely, but you could unplug them to test. I'm not so sure it is actually hibernating. If you have reset the BIOS, also check what power setting the BIOS is using. If it's S3 (STR), switch it to S1 (POS) Then it shouldn't be able to hibernate. That setting should be in 'Power Management Setup',

Make sure C1E is disabled, along with CPD EIST if either are available, also C4/C4E State Support. You may not have all those on your MB, but they are part of the power saving on some MBs. Those are usually in 'Advanced BIOS Features' depending on the MB. Most of them are off by default, but worth checking.

Those are about all I can think of in BIOS. I don't know if it would help, but you can also set the PC not to reboot on an error. That's in 'System>Advanced system settings>Startup and Recovery>Automatically restart'.

[kenmo]

PS: I also removed the CMOS battery as you suggested and left it out for 10 minutes...

Cheers

[kenmo]

Checked in bios and I have no settings C1E or CPD EIST or C4/CE State Support...

I'm using an older AMD X2 4200 and MSI mobo with Phoenix Award Bios....

I disabled a few hard drives and system still shutdown while I was using. I had to unplug and replug powersupply to get computer backup...


The only other device I have in the computer is a Hauppague PVR250 tv tuner... Haven't removed that...

[kenmo]

With only one hard drive and dvd burner attached, the computer still shut down unexpectedly.... I left the Hauppauge PVR250 card in as well...

So I re-attched the two other ide drives and ran SiSoftware's Sandra burn-in test over night and it's still running... No unexpected shutdown. When Sandra stops running I'll check the log...

At first I thought it maybe corrupt software but I've installed an Acronis Truimage of my os...

[kenmo]

I've now ran SiSoftware Sandra Burn-In multiple times, including a 4 hour burn-in three times. I've also ran a few performance modules within Sandra. The computer has not halted once....

The only thing I've done is unplug my external usb hard drive and usb LG burner... I left the APC UPS plugged in....

This is weird....

[kenmo]

I downloaded the Seagate tools and ran them against my Maxtor drive and Seagate....as well against my external Seagate. No problems were found...

My other drive is a WDC so I downloaded the WDC tools (DOS boot disc) and no problems were found.... Computer has been on since Friday doing all sorts of torture tests and it's been stable....

However SiSoft's Sandra did report my Vcore setting was higher then rated maximum.... My computer is a AMD X2 4200....

[kenmo]

Computer was fine all weekend doing all kinds of torture testing... So last night I left the computer on and idle.... Guess what, I wake up and the computer is powered off with the on/off light blinking. Only way to power on is to unplug and wait a minute or two, then plug back in....

I have hibernation turned off....

I did turn the CPU Vcore setting from 1.4 to the AMD recommended 1.35 in bios...

[kenmo]

Since changing the vcore setting my computer appears to be stable... No unexpected shutdowns yet....

Thanks for the assistance... Much appreciated....

[kenmo]

Still stable. No probs to date... Thanks for all the tips and help.... The funny thing is I wasn't trying to overclock my cpu, just going with the settings the motherboard detected....

It seems like it's hibernating than sleeping.
Try disable hibernate to see if it still happens.
