The weird thing is that in both cases, there were no errors at all in the event log related to any problem with waking up or anything else. I tried hibernating, but now when I restarted the machine it would hang restoring from hibernation. If the machine did sleep, I’d have to do five or six power cycles and sometimes go into Safe Mode to get a working computer. I did notice that when restarting the machine from a stuck sleep state, that if Windows didn’t play the startup sound, the machine was suffering the DPC Storm and logging in was almost impossible.īy the end of the week, I had completely lost the ability to wake from sleep. At the beginning of last week, I had three instances where I got stuck in the multiple power recycles.

It took a couple of reboots before I got the machine restarted correctly. What was weird about those was that after I held the power button down the restart the machine, the machine was showing the same hung signs when Windows started. The week before I’d had two instances where it wouldn’t wake from sleep. As it was so infrequent, I didn’t worry about the wake from sleep problem too much. As I have an ATI card in the machine that definitely wasn’t the problem I was seeing. Most of the reports of the problem were related to SATA drives on normal PCs and for Apple computers some were thinking it was related to NVIDIA graphics drivers. Please check for updated firmware for your system. The platform firmware has corrupted memory across the previous system power transition. The problem was very intermittent but I did occasionally see the a HAL error 12 in the Event Log: In order to get the machine back, I’d have to force power off the machine. With Process Explorer running, I could see the machine suffering from a DPC storm (Deferred Procedure Call) where one of the four CPUs was stuck in kernel mode. When I woke up the machine, the mouse would jerk across the screen and after unlocking the machine, it was nearly unusable.

As I am feeling generous on this Monday morning, I’ll even share the solution, too.Įverything was working great on my machine after I installed Windows 7 圆4, but about a month ago, I’d occasionally have a problem where once the computer had gone to sleep it wouldn’t wake up. That’s one scary problem and I thought I’d share my debugging notes on how I diagnosed the problem.

Except when the Mac Pro doesn’t want to wake up from sleep or restore from hibernation. It's worth noting, also, that the powercfg command is present in older versions of Windows, but the ability to generate an energy report is - as far as we're aware - new to Windows 7.ĭoes your system sleep as it should, or will you be trying to solve your system's insomnia with the Windows 7 energy report? Share your thoughts on sleep mode in the munity forums.As I’ve written before, Windows 7 and Mac Pros are made for each other.

We've tried it on Windows 7 RC, and we've found the report to be useful. The report (saved as a web page at C:\Windows\system32\energy-report.html) will also detail the system's supported sleep states - that's S1, S2, S3 or S4 - as well as highlight other potential energy-saving settings.

Windows 7 will then analyse the system and produce a report detailing devices and drivers that may be preventing sleep from functioning properly. This can be done by locating Command Prompt in the Start Menu (under All Programmes, Accessories) and launching it by right clicking and choosing "Run as administrator".Ģ) Once in Command Prompt as the administrator, type "powercfg -ENERGY" without the quotations, of course.

Here's how to give it a go:ġ) Open Command Prompt as an administrator. With a multitude of possible causes, I gave up a while back, but the need to save power is ever-more apparent and there's a tool built into Microsoft's Windows 7 operating system to help diagnose sleep problems.

Thinking back, I can't seem to recall ever building a PC that successfully slept when asked to do so - they've always had a tendency not to want to sleep at all, or a strong desire to wake up on their own accord. Trouble is, sleep mode doesn't always seem to work - particularly on custom-built PCs using varying components and drivers. Mighty useful, and a sleeping system can be woken up quickly - meaning an almost-instant return to the operating system. If you're not too familiar with it on the desktop, you're likely to have seen sleep mode used on notebooks - as many are pre-configured to enter into sleep when the lid is closed to help preserve battery life. Put simply, it refers to a low-power state in which PCs can turn off non-essential components and help save power when a system isn't in use. Sleep mode, or stand by as it's sometimes known, is a great idea - in theory.
