Sleep Mode - Internet Lost Upon Wakeup
May 7, 2009
I am using Acer Travelmate 8204WLMi laptop running the latest RC build of Windows 7. The internet connection is lost on both LAN adapter and WLAN (3945ABG) adapter when laptop is restored from a 'sleep' mode. I have disabled 'Power Management' of each adapter via the Device Manager. I have updated to the latest set of updates.
Disabling and re-enabling LAN or WLAN adapter to restore connectivity does not work (as it does in Win-XP). I have tried to 'log off' and log back in but this does not work either. I have discovered that the only way to restore connectivity is to re-boot the laptop.
It would appear that there is an issue of the Windows 7 code to correctly manage the LAN/ WLAN adapters. Has anyone else come across this problem?

I have Windows 7 on a Dell Inspiron 1545. Most of the time when I put my laptop to sleep and restart it Wifi network connectivity is lost and I have to click the 'Wifi Signal' icon in the system taskbar and click on my network name and click connect to regain connectivity. I have gone to 'Power Management' tab and cleared 'Allow Windows to turn off this device to save power' option as suggested by most posts but it has done nothing to help me. But sometimes even after a long sleep the laptop immediately connects back to the network and sometimes even if I just close the lid and open it after a few seconds network connectivity is lost.

About a month ago my pc started going to BSOD while trying to resume after being put to sleep. PC is 16 months old. I read the forums, etc and updated the ATI radeon display driver and the Realtek network driver but the problem persisted.I also rolled back the system using restore to before the problem began but no change. I then reinstalled windows 7 64bit using the OEM CD rom and installed all the MS updates - no change. Last week, it occurred to me that it might be a monitor hw issue so I swapped out the monitor with another I had. That seemed to solve it - for 4 days - now it's doing the same thing with the second monitor.

For the past month I have been randomly getting BSOD when my computer wakes up from sleep. My first crash was 25 days after install, and now it happens every 3-5 days. Usually just once, and I can never seem to replicate. But it happens only when the comp is waking up, never when in use. I have tried to induce it by sleep/wake repeatedly but it happens totally randomly.
I typically don't leave my computer on for prolonged periods so I can't say it wouldn't do this after being turned on for 3 days but I have yet to have a crash like that.
My system is overclocked/watercooled and had been running stable with Vista x64 since it was built in Jan 09. I installed Win 7X64 Ultimate 7100 on July 5 2009.
So, far I have tried:
Reinstalling chipset, and updating all USB pheripheral drivers.
Update video and sound drivers
Uninstalling all windows updates
Removed one 4870 and disabled crossfire
Full repair of windows (not clean install)
Overnight memtest 8 passes
Prime 95 multithread 9 hours with no failures
Last Night I tried:
Updating chipset again, bios, and raid firmware.
Disconnecting my UPS from the USB port.
I am at a loss for what is causing this. I've seen a few threads around with
ntoskrnl issues, but none that happen only on wake up. Tonight I plan to do some PSU testing.
Does anyone have any ideas about this, mini dump file is attached ?

I have a problem with the hybrid sleep mode.
Whenever I try to put my notebook in sleep mode everything works ok, also normally waking up the system.
But when I disconnect the power cord and restart the system, Windows tries to resume its state but suddenly stops with a black screen and a blinking cursor.
I have absolutely no problems with normal sleep and normal hibernate (shutdown -h).
For a short time hybrid sleep worked only when I put the system to sleep with the notebook FN keys, but not through the Win start menu.
Now it doesn't work at all. Maybe this was also just a coincidence.
Can anyone help me?

I purchased am HP Mini 110 netbook three weeks ago to use in school while I leave my heavier and bigger laptop at home. It came with Windows 7 Starter, but I took the (bad) decision of installing an illegitimate copy of Windows 7 Home Premium because I found starter somewhat clunky.
I downloaded the ISO from a torrent and created a bootable USB. I just run the installer from Windows itself and the installation took about 45 minutes. After that I installed the drivers and everything went fine for a week. I also used the ''activator' that came with the torrent.
This Friday, as I resumed from sleep, the system froze as I put my password for a few seconds and soon after I got a BSOD and the computer shut off. As it rebooted I got a message saying that no OS is installed and that no HD is detected. I attempted to run some diagnostic tests through the BIOS but it tells me that not HD is detected. I even attempted to install Ubuntu and it doesn't detect a drive either.
I already talked to HP costumer service and they'll soon come to pick up the netbook to get it serviced, but meanwhile, I sent it to a technician to find out what is wrong with it. The news I got from him were that the HD was completely dead.
Previously, I had unplugged the HD to make sure the ribbon was not lose and plugged it again. Now, I am in this dilemma: Would my HP warranty void if they find out I installed a pirated OS which arguably caused the hardware to fail?

Machine: Dell XPS17 laptop (702x)Windows 7 home premiumWifi adaptor: Intel Wifi Link 1000 BGNRouter: Belkin F5D7634-4 802.11GReconnection takes 3 or more minutes to establish after sleep. Tried all the on-line advice e.g setting power scheme to max power; unticking box in adaptor settings 'Allow computer to turn off this device'.Tried to update drivers for wifi adaptor but the update process says I have the latest drivers. However Dell's driver site analysed my laptop and says there is a later driver for download. Tried installing this but was stopped by message saying it wasn't authenticated/certified so terminated.

I was having problems getting virtual xp mode to boot on my windows 7 computer. I deleted windows xp mode and reinstalled it. I was then able to open xp mode but when I opened Acess 2003 and looked for my database for my business It seemed to have disappeared. Did searches in xp mode, on windows 7 in all drives.

power off and unseat the video card, re-seat it, and power back up...

Would this be a software issue, problem with motherboard or video card?

I bought a new notebook running windows 7 64 bit a couple of months ago After running a full system scan with Kaspersky anti-virus a couple of days ago I now have a bug with sleep mode - After going into sleep mode, the user with my picture icon is locked meaning that I can't enter my password to log back in - the password box doesn't show.With the ASUS face recognition scanner I'm logged back in, but everything is 'buggy' e.g. if I click on the start button and hover over that entire area it goes into sleep again, or if i click on the bookmarks on chrome it doesn't show them, instead it click on an actual site within the bookmarks.After going into sleep the only way to enter and return to a normal state is to click the 'switch user' whereupon, my user picture icon reverts with the password boxI have tried a system restore but this didn't work.

Since a few days my PC developed an unusual behaviour: it goes to sleep mode at random intervals ! sometimes it does that at windows start up for several times...
I had microsoft security essential installed and read on some forums that it could be the reason for this problem: I unistalled that. Then I run online scanned from ESET nd Bitdefender: all clean.
Then I installed avas free edition (as I was without any anti-virus software). Did a complete system scan with no problem. I messed up with the power consumpion settings with no results.
The only solution I could find was to use the software "Dontsleep.exe" which I found googling around: it works ! I looked up all the running services and application at windows sturtup and disabled a lot of them with no results.

So this might be the wrong place for this thread but I didnt see a computer specific section so i picked this just incase it is related to my windows. Anyway the problem i am having is that every so often, more often then not actually, when my computer hibernates from inactivity, it cannot be woken up. I click the mouse, press everything on the keyboard and nothing will happen. I even try pressing the power button yet that does nothing. The power button just keeps blinking as normal when in sleep mode. I also tried Holding down the power button, in hope to force shutdown the computer but that did not work either. The only way anything happens is if i unplug the computer and then plug it back in. Unfortunately i know thats really bad for the computer but i dont really have a choice.[CODE]In addition, i have restored my computer to factory defaults, aswell as installed all the latest drivers

After putting my computer to sleep, upon waking I receive an error code, which should be present in the dump file. I closed the error window before copy pasting it in here. I will update the post with the error information next time it happens. This only happens when putting my computer to sleep. Hibernate and shutdown do not have this problem, and I have not received any BSOD's during use. This has been happening for about 10 days. My memory set up is kind of strange. I have 2x1GB 1.8V ram and 2x2GB 2.1V ram, both DDR2, and both running at 2.0V. I didn't want to overvolt the 1.8V ones too much. The timings are slightly loosened on the 2.1V ram to match those of the 1.8V ram. I have run Memtest86 with no errors. My hard drives have also checked out fine.I have my q6600 overclocked to 3.0GHz, with a voltage increase, CPU-Z is saying it is running at 1.408V. I have run plenty of Prime95 tests. No stability problems, and temperatures are always acceptable. I have had it at this overclock for 7 months, ran at stock the previous 4-5 years. My GTX 460 is overclocked as well, always has been stable as well, with temperatures plenty low enough.

My pc is shutting down more and more frequently so that it now happens every time I close the lid for sleep mode. In Event Viewer there are numerous "Event 41, Kernel Power" warnings.

I installed 7RC a couple of months ago. Since then whenever my pc sleeps I can not wake it up. It used to wake up fine in XP. To get it going again I have to cold reboot or pull the plug. When it comes back up everything I was doing is still there, I just have to enter my password. I think I have all the settings right but if someone could run me through everything that needs to be set I'd be really grateful.

I am not savvy in this kind of stuff. My husband has a home built computer that runs our tv system with windows media center. He had to leave on a military deployment and right before he left he had to reinstall the OS. Since then the computer refuses to wake from sleep mode. I have to scram it to get it to come back up. Since we run the media center it ought to wake up to record automatically, but it isn't doing that either. I've checked all the power options but that doesn't seem to be the problem. Although, at this point, I really have no clue.

From time to time Windows 7 will not go to sleep (only the display will turn off). I have searched various forums and tried the following fixes: I have already made sure that network adapters are not allowed to wake up the computer. I typed "POWERCFG -ENERGY" in the command prompt (as administrator) and an energy report was generated, which reported this error: System Availability Requests:System Required Request The service has made a request to prevent the system from automatically entering sleep.
Requesting Service Spooler Opening task manager, I see a process running called "splwow64.exe" -- is this the spooler preventing the computer from sleeping?

To prevent my computer from going out of sleep mode by itself I have to unplug my ethernet cable, that's 1 problem but I don't really care.
The other problem is when I come out of sleep mode, my DVD player opens by itself, I close it, and it reopens.

Windows 7 is freezing in sleep mode now... I don't think it's my drivers or anything because 2 updates earlier it worked fine. I'm wondering if anyone knows if this is an RC problem, or if something is wrong with my computer. I hope not since this computer is only 2 week old... There is like nothing on it and everything downloaded has been from a disk so no viruses (well except kasperky anti-virus but I HOPE that would be clean lol).
Basically when I put it into sleep manually, I cannot get it out, and my power/reset buttons do not work, I actually need to turn off the electricity.
Oh, and it's not my screen considering I CAN turn my screen on but it goes right back into powersave mode (sleep mode). I DID force it out once, and it said no signal from the computer even though the computer is on. This leads me to believe it is the OS (or god forbid one of my parts).
I just realized something... I have on HD connected via sata cable, but I took the power away from it (I wanted to hear something). I mean is that the possible cause? I doubt it though since it's not registered as an HD due to having no power... And my sound card light is on, so I'm assuming that is still on when I put the computer in powersave mode... Maybe that's an issue?

I am still having bug and freeze problems on all of the computers that I have been testing on since the first release in November.
I am currently testing both x64 and x86 versions on 4 of my PC's and still having minor bug issues, and the major freeze problem.
I do not Just use my PC's for e-mails, browsing the web and gaming. I primarily use them for Engineering Design Work and they need lots of resources to operate efficiently. My primary Base unit is the one I do most of my work on and the Most efficient Operating system on it is Windows XP x64 (sp2) and customized. (Not the Basic install of services and registry sets).
The freeze issue is random and it happens when my PC's go into sleep mode. Some times the will wake up normally, but way to often they will not wake at all, I have to force re-boot. And no error logs related to sleep mode issues, only the E-ID 41 (forced re-boot). This has happened on all the releases from 7000 to 7127, and now 7600, the releases from 7137 to 7229 never had this problem. And this has happened on all my test PC's including Laptops and Desktops.
I have tried many changes in settings for Power Settings (Advanced), Network Adapter Settings, Monitor settings.
Ideally I want my Network Adapter to stay Active on my main box so I can access files from my other computers any time I need them, I want my HDD's to go to sleep when not in use so they will live for a while. and My Monitors to shut down when not in use.

When system goes to sleep longer than a hour and you wake it up the bottom third of the screen freezing. The top 2/3's get split like window pane a when you scroll the top 2/s's will scroll but the bottom 1/3 will remain as it was before sleep. Also the bottom third wont have any hover icon effects though icon will still work, the task work as intended. If I restart the programs the will work fine but windows has to restart for icon hover effects to work.

if i am going to leave for about 1-2hours, should i put the computer to sleep mode or simply shut it down?
I was told that sleep mode warms up the computer also. So its not good to go sleep mode. Isit true?

When I try to put my computer to sleep, the screen goes into sleep mode, yet literally nothing happens with my tower. Then after a second or two, the monitor wakes back up and shows the login screen. I've tried checking powercfg /requests and -lastwake, and requests shows "None." across all topics, and lastwake says Wake History Count - 0.

I just built a mini ITX HTPC in a silverstone sg06 case (Zotac H55 ITX MOBO, 4GB DDR3 Ram, 32GB SSD, and intel i3 built in intel HD graphics)All works fine and I am very happy with it. I am using XBMC for my media program and I have the Logitech Dinovo Mini Wireless keyboard.. I use the SLEEP button when I am done watching a movie and when I want to watch a movie "lets say in a few days" I quickly press any button and instantly I am in XBMC again with my movies list.Does it use alot of power? IS it dangerous to leave pc on stancby overnight..? Is it harmfull for the hardware.?I have been reading mixed reviews.

First the system specs:
Intel DX48BT2 motherboard
Intel QX9770 3.2 GHz Core 2 Extreme
Nvidia GTX 295
8GB of OCZ 1333MHz DDR3 Gold Series RAM
30GB OCZ Vertex SSD
1TB Samsung HD103UJ HDD
Windows 7 SP1 Public Beta
For two nights in a row whenever I have put my computer to sleep before I go to bed it has not been able to exit sleep mode the following morning. The screens get no signal even the the computer is on. I should note that I have hibernation disabled on this computer due to the fact that the SSD boot drive is so small and an 8GB hibernation file would be too large. Instead I enter standby. I should note that last night as I was entering sleep mode I accidentally hit a key which caused it to come right back out of sleep mode before the fans had turned off.
