Windows 7 RTM Black Screen of Death after Forced Shutdo

[v0id]

Microsoft has informed users of an issue that prevents Windows 7 from starting after the computer the OS is installed on has been forced shut down. According to the Redmond company, this issue affects the 32-bit flavors of all Windows 7 editions. In order to replicate the scenario, end users need only to force the machine Windows 7 is installed on to shut down. A common action in this regard would be to hold the power button of the computer pressed down for a few seconds. After the PC shuts down, users will discover that it will no longer boot again. Microsoft indicated that the startup process would stop at a black screen and Windows 7 will not boot.

The software giant informed that “This problem occurs if the following conditions are true: Data Execution Prevention (DEP) is disabled either in the BIOS or in the operating system. The system is configured to enter hibernation or to enter hybrid sleep mode when the power button is pressed. The language version of the operating system that you are running is a double-byte character set (DBCS) language. For example, you are running a Chinese, Korean, or Japanese version of Windows 7 on the computer.”

There is a simple workaround designed to let users reclaim full Windows 7 functionality, and get the platform to start up under normal parameters. All that users need to do is to boot the computer via the Windows Preinstallation Environment (Windows PE) disc for Windows 7. Starting the machine in normal mode will not be a problem. In the eventuality that a Windows PE disc is not on hand, a Windows 7, Windows Vista, or Windows Server 2008 installation DVD can also be used. In addition, the Redmond company is providing a hotfix in order to help Windows 7 users prevent this scenario from happening in the future.

“This problem may also occur in a rare scenario where the power goes off when the computer is entering hibernation. By default, hybrid sleep is enabled on desktop computers. Therefore, if a desktop computer is configured to enter sleep mode when the power button is pressed, it actually enters hybrid sleep mode,” Microsoft added.

LOL!

My golly , I knew there was a GOOD reason that I never use HYBERNATE - it is disabled. or SLEEP it is disabled.

woosh, thanks for the info.

All my pc's use standby. (hybrid is off)
I never use hibernate.
I rarely shut them down or reboot. Only if it is required.
I have no problem what so ever with standby.

The second scenario only occurs with hybrid enabled,
in which case the pc actually hibernates in stead of standby.

Greetings

Edit: ah, I see you edited standby to SLEEP.

Another good reason not to use HYBERNATION and HYBRID SLEEP. For myself, I ALWAYS had problems with those where I could simply couldn't boot back. Always.

Updated BIOS and drivers should see you right.

Sleep and (hybrid) hibernation are awesome. Quick ON/OFF, better for the environment than just leaving the thing powered up while you're not using it - what's not to like?

I agree although I admit I use standby cause waking is instant.

I measured consumption in standby with a watt meter and it read 2.6 watts.
In Hibernate mode (not hybrid) and PSU on/off switch still on, it read 2.1 watts.
So the difference even over a year (182 watts) is negligible.

A small 25 watt lightbulb left on for 8hrs consumes 200 watts.


I can live with that.

Those numbers are going to be entirely hardware-specific and some will be (far) better than others. There's also the issue of heat. In theory, a hibernating laptop draws zero power because it's off (assuming it's not in its hybrid phase). That's useful in situations where it has to spend hours couped up in a fluffy and air-tight laptop bag under your plane seat, or in the overhead locker.

In the interests of pedantry, it consumes 200Wh

Couldn't resist this one, damn I should be sleeping.

Differences between systems will be negligible never the less.
Maybe 0.5wh
Only RAM is kept under power in standby. (theoretically)
The rest is the PSU itself, even when it's supposedly off.

True, although my lappy in standby in my fluffy probably not airtight bag, stacked between a couple of books,
stays completely cool too. No warmth humanly detectable.

True, and true, that was quite pedant.

Goodnight, see you tomorrow.

Hmm. I always either restart or shut down. Never use hibernation or sleep.

Interesting that it only effects 32-bit though.

Why am I not surprized to hear that?! Even with previous versions I come across people always running into a seemingly endless list of problems when coming out of hibernation and never seeing a full restart in order to see Windows once again load things properly and see them made active.

Hibernation and sleep modes are simply for energy saving practices when a system is left idle for lengthy periods of time rather then shutting everything down. Typically this is the norm for office workers and the like while on lunch breaks, short customer visists, inhouse meetings, etc..

The home environment on the other hand is where people run multimedia, pc games, and other addon devices even compounding problems when not regularly shutting everything off for the night or when away at work or school. For systems with all these types of applications and not simply word processing and Office type softwares being the main diet you have to expect complications.

Have anybody ever wondered why they don't offer an auto start time? I thought of that while I was reading this thread. If somebody were to start on there computer everyday at a certain time then it would be handy.

You can set auto start time in BIOS.

A colleague of mine did it all the time.
Very annoying when he had a day off.

Good luck

I always use hibernate as my laptop runs out of battery when i m not using it.

A laptop is where you want to conserve as much power as possible since you are on battery. There you have to think smart since you only get about 4hrs. tops with most batteries on a full charge.

For desktops the option commonly seen in the bios is the lan wakeup option. You can power several office machines by simply sending out one main call which is practical for the typical business instead of having someone running around to each individual machine for the task.
