Startup issues with Windows 8 after sleep mode

Hi,
So i have the power button set to sleep, and when I press it, my U410 Ideapad with Windows 8 goes to sleep, like it should. When I press it again to wake it up, it either: freezes and doesn't allow me to pull up the lockscreen, or does lift the start screen only to let me barely begin to type a password before it freezes. Any ideas?

Hi bisopia,
Thanks for posting and welcome to the commmunity. Upon reading your post I was just wondering when you put you machine to sleep, how long do you leave it for, before waking it up? If you put it to sleep for 5-10mins, does the freezing still occur?
To be honest I'm not entirely sure what's causing this but what I would suggest is for you to update the Intel Management firmware.

Please do give it try and let me know.

  • Issues with windows 7 after Labview 2012 installation

    Hi
    I am having some issues after installing Labview 2012 on machines running Windows 7. Firstly, after installing a program on a user's machine, the machine sometimes takes 20 minutes to boot up before the user can log on. The 'Please Wait' message appears during this time. This is also the case on the development machine.
    Secondly, on the development machine, I am having an issue when trying to run compiled programs created in Labview. When installing, everything works fine but when I go to open the program, it appears on the task bar for a brief period before closing. It does not appear in the task manager either. I have tried this on 2 other machines with windows 7 and Labview installed and still get the same issue.
    Any help on these matters would be much appreciated. Thank you

    Hi
    Firstly, looking at the issue with the slow Windows 7 boot up time, as Norbert_B suggested the Windows Event Log is a good starting point to find the root of the problem. The following link describes how to launch “Event Viewer” and some common problems:
    http://itexpertvoice.com/home/what%E2%80%99s-taking-so-long-how-to-fight-slow-startup-times-in-windo...
    Aside from that, if your computer is part of a domain, the problem may be connected with certain Windows Services that start automatically on boot up. I recommend trying the following steps:
    Open up “Control Panel” go to “System and Security” then “Administrative Tools” from here launch “Services”.
    Sort the list by name and scroll down to “Network Store Interface Service” right click and select “Properties”. Under the startup type dropdown select “Automatic (Delayed Start)”.
    Next scroll down to the “WebClient” service again under “Properties” this time select “Disabled” under the startup type.
    As for the problem with running LabVIEW executables, I have a few questions:
    Do you get any error codes when it closes automatically?
     Does this occur for multiple executables or just one in particular?
     Does the code run without a problem within LabVIEW?
     Have you tried to update LabVIEW?
    What hardware are you running?
    Without this information I can only think it may be caused by the Windows Data Execution Prevention (DEP) security feature. So you can try the following steps:
    Right click on “Computer” and select “Properties”.
    Click on “Advanced System Settings” and select the “Advanced tab, then under the performance section click “Settings”.
    Click the “Data Execution Prevention” tab.
    Make sure it is activated for essential Windows programs and services only, or you have an exception for your EXE.
    You may also find the following link helpful on debugging applications:

    Let me know if these solve the problems.

  • Hello. My mac pro early 2008 restarts after sleep mode and it works slower. I tested it with apple hardwear test and it seems to be ok. Thank you.

    Hello. My mac pro early 2008 restarts after sleep mode and it works slower. I tested it with apple hardwear test and it seems to be ok. Thank you.

    Try this:
    clone your system and repair it with Disk Warrior instead
    Or try a clean test system install on another drive
    A must: SmcFanControl 2.2 - a mere 400 rpm extra to keep air cooling up
    Try to run w/o externals. MyBook included.
    Is that a 7200.11 1TB? they had a lot of issues.
    Run AHT off your OEM DVD.
    2008 had to have EFI and SMC updates to deal with freezes on wake from sleep, and like all models, high inrush current.  Hopefully you have a UPS and is 1500VA unit.
    When you do hard restart from power button, you almost certainly add more directory errors and to files requiring immediate attention to repair and rebuild the directory; and to scan and repair and delete cache and temp files and folders. A must. Invest in bootable backups SuperDuper along with Disk Warrior (or TechTool Pro 6, maybe Drive Genius 3 but I'd rate that #3).
    TimeMachine has its own bad habits, especially with Green drives and some externals.
    Try to rule out everything and then add back one at a time.
    And it may just be time to replace the 8800, very common, a couple threads this week, and it is 3 yrs old.  Might want ATI 5870 or 5770.

  • No video after sleep mode.

    Brand new home built system (all new components unless noted otherwise) running Windows 7 64-bit Home Premium on the following hardware:
    MSI X58 Pro-E motherboard,
    Intel Core i7-920 (2.66) CPU,
    Enermax PRO82+ 525W powersupply,
    Sapphire ATI HD5670 1GB GDDR5 PCI-E video,
    8GB Corsair 1333MHz RAM,
    WD Velociraptor 150GB 10,000 RPM boot drive,
    WD 500GB Caviar Black for file storage,
    Plextor DVD-RW,
    CoolerMaster case.
    Older Viewsonic VP2030B monitor,
    Older Microsoft Desktop 6000 V2 keyboard/mouse.
    With standard Windows 7 power saving features enabled, the following
    intermittent problems occur:
    After the system has gone into sleep mode, the video card provides no signal to the monitor. Moving the mouse or touching keys on the keyboard obviously bring the system back out of sleep mode, but no video signal is received. Unplugging the DVI-D
    cable from the card results in the Windows sound indicating a change. Plugging it back in, results in a Windows sound indicating the change. This happens when you unplug one end of the cable, it doesn't matter if it is at the monitor end or the video card
    end - as long as the other end is of course still plugged in. The only resolution to this "no video" state is to reboot the computer with the power or reset button.
    On some occasions when turning the PC on, there is no video signal. The system boots properly (although the BIOS screen takes about 15 seconds to appear - something MSI says is OK), and can be shut down with the correct keyboard sequence. The monitor
    runs through VGA, DVI-A and DVI-D, but no signal is ever received so it goes into standby mode. 
    When the computer boots properly, usually while it is still loading Outlook (which is set to start automatically), the screen goes completely blank for 5 or more seconds, then comes back on and the monitor menu indicates that it is running at the correct
    resolution, and then the video works correctly from there on in - unless it goes to sleep.
    On some occasions, when recovering from a "no video after sleep mode" incident, everything on the screen has been moved towards the upper left side of the screen. The Outlook window which is normally quite large (80%) and centred on the screen has been reduced
    in size to about 50% and shoved into the top left corner. Also, the 4 gadgets that normally run vertically along the right side of the screen have been moved up and towards the middle of the screen, one or two of them often overlap others.
    Things I have done/tried:
    All Windows 7 updates,
    All motherboard BIOS updates,
    All video card drivers and software updates from ATI,
    Replaced the DVI-D cable,
    Uninstalled the video card and drivers, and moved the card to a different PCI-E slot,
    Replaced the video card with another Sapphire ATI HD5450 card (temporarily).
    Sapphire thinks it's a hardware problem with the original card, but since temporarily replacing it with another card, the problems continue, so I doubt that is the issue. (Plus I have to pay $25 to ship the apparently defective - under warranty card - back
    to them.)
    These problems have happened intermittently since the system was built in January 2010 and they seem to be quite random, sometimes not happening for weeks, other times happening every few days. Sometimes the system is in sleep mode for 1/2 hour and it happens,
    other times it is in sleep mode for hours and it happens (or doesn't).
    Any help would be appreciated.

    Hi again,
    OK, I finally got around to trying this. I still have to check if that actually fixed it, but I managed to get into the "Factory" OSD screen.
    I had my system running, disconnected my new monitor and plugged in the flaky old Viewsonic. I then:
    1. Depressed and held down the #2 button, then depressed and held down the Power button,
    2. Almost immediately the amber power light turned-on, the backlight turned on and the output image from the PC showed up.
    3. The On Screen Display (OSD) for all the monitor setting came up (at the bottom of the screen instead of the middle where it normally is), and underneath the Main Menu window in the OSD, along the bottom of the overall OSD window, the word "Factory" appears
    in the middle between the control button keys (#1 for exit, and #2 for enter). (It's not normally there.)
    4. Using the down arrow key on the face of the monitor, I highlighted the "Factory" menu item, pressed the #2 key and voula! there was a whole new simple white text on bright blue background window, which among all sorts of settings included "Factory Reset"
    (which is the default selection).
    5. I pressed #2 again to accept and it was done.
    All that is left is to do is some user testing to see if the monitor behaves as new.
    Additional informtion: in the top of the "Factory" menu it reads: "LOVP AU Ver.0.36"
    I took photos of everything and will post them on my Flickr account. To find them go to wwww.flickr.com, click on the search button, then on the next screen click on the People tab, enter my name and click search.
    Thanks again for the advice.

  • Desktop computer crashes after sleep mode since upgrade to Snow Leopard

    Since I upgraded my power Mac to Snow Leopard in December, I've had nothing but problems, all of which appear to stem from when it comes out of sleep mode. This computer and all applications were rock solid in Leopard! I also have a mac book running identical programs and that IS rock solid on Snow Leopard. I have a 2 x 2.8 GHz Quad Core Intel Xeon processor with 10 GB ram.
    I did a complete re-install of SL and all programs as per the Apple instructions.
    Basically, the computer crashes after sleep mode. I've tried all the fixes I've read on the net. Here is the report thread from the last crash. Does it mean anything or throw any light on the problem to anyone?
    Thanks,
    David Wright

    The problem has been identified as the RME fireface400 audio driver. I've spent some considerable time experimenting to identify the culprit. It's clear that this is what is causing all my problems since Snow Leopard. Whether it's exclusively the drivers fault or partly also due to a conflict with apple SL, I don't know, but I have crash reports if apple want to see them.
    From your first post, it appears you are using Fireface audio driver version 2.64. RME released a new Snow Leopard compatible driver (version 2.65) last December. It is available at RME: Downloads. (There is also a firmware updater for the Fireface 400 there, which you might want to check out.)
    It isn't at all unusual for a new OS version to require new drivers for third party hardware. References to this can be found all over the web, in "read me" files & other documentation, etc. -- it doesn't just apply to OS X but to Windows & other OS's as well. (One of the biggest problems with Vista was poor third party driver support.) In fact, the X-Lab "Resolving Kernel Panics" article specifically cautions users to make sure all such drivers are current. See section 6.1 of that article for more details.
    I don't know if you missed all this somehow, but if you haven't already downloaded & installed the new RME driver (& possibly the firmware update as well), then do so now. While you are at it, check for other similar updates for any other third party hardware devices you use, using the info in section 6.1 of the X-Lab article as a guide.
    Hopefully, this will resolve your issue, which (as already mentioned) is kernel panics, not crashes. If you still have problems, post more about them, being mindful of the difference between application crashes & kernel panics. Because they are fundamentally different, they have different cures, so we will need to know which type they are to offer effective help.

  • Hello my Mac Air is frozen on the grey screen (with the apple symbol, sleeping mode, restart-and off button), once you turn it on.

    hello my Mac Air is frozen on the grey screen (with the apple symbol, sleeping mode, restart-and off button), once you turn it on. I Can`t press any button.My Mouse still works. Battery is charged. Alt-cmd-escape doesn`t work It even after a forced shutting off, the problem is the same.   what should i do? Thank you for your help.

    Take each of these steps that you haven't already tried. Stop when the problem is resolved.
    Step 1
    The first step in dealing with a boot failure is to secure your data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since your last backup, you can skip this step.   
    There are several ways to back up a Mac that is unable to boot. You need an external hard drive to hold the backup data.
         a. Boot into the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.”
    b. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, boot the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
    c. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
    Step 2
    Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to boot, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can boot now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
    If you've booted from an external storage device, make sure that your internal boot volume is selected in the Startup Disk pane of System Preferences.
    Step 3
    Boot in safe mode. Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Post for further instructions.
    Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
    The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
    When you boot in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, your boot volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 5.
    If you can boot and log in now, empty the Trash, and then open the Finder Info window on your boot volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then reboot as usual (i.e., not in safe mode.)
    If the boot process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
    Step 4
    Sometimes a boot failure can be resolved by resetting the NVRAM.
    Step 5
    Launch Disk Utility in Recovery mode (see Step 1.) Select your startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
    This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then reboot as usual.
    Step 6
    Reinstall the OS. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
    Step 7
    Repeat step 6, but this time erase the boot volume in Disk Utility before installing. The system should automatically reboot into the Setup Assistant. Follow the prompts to transfer your data from a Time Machine or other backup.
    Step 8
    This step applies only to older Macs (not current models) that have a logic-board ("PRAM") battery. The battery is distinct from the main battery of a portable. A dead logic-board battery can cause a gray screen at boot. Typically the boot failure will be preceded by loss of the startup disk and system clock settings. See the user manual for replacement instructions.
    Step 9
    If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store to have the machine tested.

  • Memory RAM upgrade won't wake up after sleep mode

    i just recently purchase a pair  16GB RAM of crucial  CT2K8G3S160BM for newegg.com. Yeesterday i try put this on my macbook i7 intel 2.9 processor that crucial said is compatible. but found out everything was good until i close my mac lid for hibernate. What happen is, it won't wake up no matter what i do until a way of reset SMC. BTW i try stick by stick to plug in together with my original 4gb RAM together found out 1 was ok and other one was not. But somehow why the info of hardware show that memory ram 16GB was installed and was OK. Everything was run smooth even booting. The only problem is won't wake up after sleep mode. I already try reset smc, pram, delete startimage, delete powermanagement.file and also sudo hibernate 0-7. Did anyone had this same issue of me. I'm my curiousity will it be the bad ram or software problem.

    i just google around and found this two both crucial ram. Both spec are the same but different model no.
      CT102464BF160B 16GB  and mine is CT2K8G3S160BM are this 2 same? but both same spec.

  • Weird issue with Windows Server 2008 R2 Print Server

    I have an issue with Windows 2008 R2 (VMWare Hosted) running Windows Print Server. 
    Prior to a small network change, the print server was working well, hosting about 80 different networked printers from various vendors. 
    We made a change (that we ended up rolling back) to the Client's DHCP Scope OPT 006 (DNS Servers). The DNS servers never quite worked right and broke AD authentication to different servers, and was just a mess.
    After rolling back we are not able to keep the printers online. If we ping them from the print server, the printer(s) never wake up, when a print job is submitted. If we ping them from one of the access switches, they work fine (until they fall back asleep),
    to prevent this, if we start a ping on the server AFTER waking them up from the Switch Ping, they stay online and no problems. 
    If we stop the ping, they fall back asleep at some point, and again, won't wake up without intervention/switch side ping. 
    Has anyone experienced anything like this? Any tips on how I could possibly resolve it? 
    Thanks in advance.

    Hi,
    According to your description, the issue seems to be that the printers can't keep online. Sounds like a power managerment issue. Why these printers fall into sleep? Have you consulted this issue with the manufacturer of these printers? Do these printers
    fall into sleep if them lose the contact with printer server? Have you tried to reset the printers?
    >>We made a change (that we ended up rolling back) to the Client's DHCP Scope OPT 006 (DNS Servers).
    DNS client will cache the recently queried records. If the DNS server has replied with a wrong records, communication issues will occur. To clear the DNS cache on a Windows device, please run the command below:
    ipconfig /flushdns
    Best Regards.

  • Upgraded to lion now my wi-fi loses connection after sleep mode, it still shows as connected but does not go out to the internet. Please help

    After I upgraded to lion I have been having constant issue with my wi-fi after sleep mode. I close the lid and when I reopen I open safari and cannot connect to the internet. Wi-fi is on and I am connected to my router, but it doesnt seem to be on the internet. Now how I resolve this issue is turn of the wi-fi and turning it back on, then i am back on the net. this is mos-def a bug i have never had that problem with snow leopard. Please assist or provide hot-fix

    I have the same issue and have to cycle the wireless modem on the laptop. Doesn't matter if I'm on a preferred netowrk or no, or if I stay on the same network or move. I come out of sleep, I have to cycle the modem.
    It's not life threatening, or anything, but it's a hassle. I didn't have the issue with Snow Leopard.

  • Don't work App Store after sleep mode

    Hello!
    I'm sorry for my english :-)
    My MacBook Pro 2011, updated to OS X 10.9. Not working App Store app after sleep mode - not show anything in the window at all (shop, purchase, updates), load the CPU and eats memory. After rebooting Mac all right again until the next sleep mode.
    How can I fix it?
    Thank you.

    Quit the application.
    Go to Finder and select your user/home folder. With that Finder window as the front window, either select Finder/View/Show View options or go command - J.  When the View options opens, check ’Show Library Folder’. That should make your user library folder visible in your user/home folder.  Select Preferences/com.apple.appstore.plist. Move the .plist to your desktop.
    Open the application and test. If it works okay, delete the plist from the desktop.
    If the application is the same, return the .plist to where you got it from, overwriting the newer one.
    Thanks to leonie for some information contained in this.
    You might need to redo the View settings after an update.

  • Black Screen after sleep mode, and even after restarting

    I've had problems with black screen before, usually after sleep mode. I usually then restart the computer, the sound of turning the computer on is heard and then it is working perfectly...however since last night I tried to restart it, the sound of turning the computer on was heard at a lower level of volume, but the black screen is still there...I have disconnected the computer, taken the battery of the MBP reinsert it, plugged it and turned it on. It worked once, but it is no longer working...PLEASE HELP!!!!!! SOON!!!! I have projects to turn in in a couple of hours.
    By the way I have the Snow Leopard OS system

  • Yosemite upgrade: function keys no longer work, no keyboard lights and have to sign in twice after sleep mode.  Anybody else having these problems?

    Hi,
    Since I did the Yosemite 'upgrade' last week I have been having problems with my MacBook Pro that never happened before.  The most frustrating problems involve my keyboard which doesn't light up (checked my settings and they are correct) and the top row of function keys don't do anything so I can't adjust the volume, brightness, etc.  Then if my screen goes into sleep mode, when I wake it back up I have to sign back in twice - I never had to sign in at all after sleep mode before.
    I'm finding that in order to get it working properly I am having to completely shut down and start up again but when the keyboard problems are happening I can't get anything on the apple dropdown to work either (i.e. shut down, restart, etc) so I can only shut down by pressing and holding the on/off button.
    I've never had problems with my Macbook before and feel like Apple have completely ruined it in one update!  I've had a look through other posts on here but can't find anybody else having these problems so I would be really grateful if anyone could help me and offer me some advice on how to sort it out.
    Thanks!

  • WLan fails to connect after sleep mode - Satellite T110-10x

    Hi,
    Everything works fine, wireless connected.
    After sleep mode - it fails to connect although it detects my wireless network.
    I've tried the latest Realtek driver, still no good.
    I've verified that my setup is not to turn down wireless in the power options.
    Any idea?

    Hi
    Where did you find the latest WLan driver?
    Here on this Toshiba driver page you can find the latest Wlan driver:
    http://aps2.toshiba-tro.de/wlan/
    I recommend uninstalling firstly the old driver and then to install the newer version.
    Furthermore its necessary to update the BIOS. I read in the forum that similar issues could be solved by BIOS update.

  • Ipod classic wont start up or reset after sleeping mode

    Hi. I've just got a new iPod Classic 160Gb, one week old. Everything is fine except that it won't turn on after sleep mode is on. I cant do the restart. The iPod somehow does not response to the menu+start buttons at the same time. It however wakes to live when I plug it to the computer. But when not in use and after it enters sleeping mode I still cannot turn it on. The only option again is to plug it to the computer. This is not right...?? It has the latest software and I have reset to original setup through iTunes.
    Anyone know how I could solve this problem? Could this be a hardware fault?
    Robban22

    Hi, did you ever find a fix for this? My iPod Classic has just done the exact same thing - red X, won't be detected on Windows, and won't go into disk mode (will go into Config mode, but I can't see anything in that mode that will help).
    Would really like to be able to put this into disk mode so I can try to restore my files...
