Kbfiltr driver in sleep mode win8

Hi 
I have developed keyboard driver using WDK kbfiltr sample from msdn
But I have stuck in place ie In one of my client having asus laptop with windows 8 But when he keeps laptop in sleep mode
after waking from sleep mode kbfiltr.sys stop responding . Is there any way to wake up driver  
I want to ask one thing that Now when ever i create driver service (that uses kbfiltr.sys) i need to restart the system but is there any way to start driver service without restart.

you can restart the driver by restarting the device itself. Disable/enable is the easiest route. You need to debug the driver on the Asus laptop where it hangs. The driver will see power up requests so the hang will be in the processing/power up in the
driver implementation

  • Finder crashes with External Drive on Sleep Mode

    I purchased my new iMac 21,5" less than a week ago, and I haven't had a problem with it except for one that it's been bugging me a lot.
    I have a LaCie 1TB Quadra d2 external drive that I use to store footage (since it's HD, the filesize won't fit in my 500TB internal hard drive), but I noticed that sometimes when LaCie external drive enters in Sleep Mode, the Finder freezes and the only two ways around this, is to force reboot, because the Finder won't answer and won't open again, or unplugging the external drive without ejecting him first, which it's not safe for me to do, because I'm afraid of hurting the device, and the files in it are pretty important.
    This happens almost everytime, especially after a long time on sleep mode. I usually leave Final Cut Pro transferring files all night (since it takes a long time) so I kinda need the sleep mode, but when I wake up, Finder and Final Cut Pro won't answer.
    I updated to Snow Leopard 10.6.8 on day one. Is there a way to fix this? Is it normal? I read somewhere that some users were having trouble with external drives on Sleep Mode, but I can't seem to find any further information about this problem.
    Thanks!

    I've got a MacBook Pro 13.3" that's a little over a month old, with a LaCie 1TB LaCie d2 Quadra with USB 3.0, #301542U and I'm suffering the same problems and a few others with it. I've got a partition on it set up as my Time Machine backup drive. I've turned off the Put the hard disk(s) to sleep when possible in the Energy Saver preferences but I'm still having the sleep problem with it. According to the LaCie Manual:
    By default, your drive will enter Eco Mode after 30 minutes of inactivity in order to conserve energy. To exit Eco Mode, simply access data on the drive and the disk will automatically restart. You can manage this feature using LaCie Desktop Manager. Click the Eco tab.
    The LaCie Desktop Manager (in my case) only takes me to the Energy Saver Preferences in OS X to adjust the time there. Turning off Put the hard disk(s) to sleep when possible doesn't seem to make any difference, the drive still goes to sleep after 30 minutes. However, after 15 minutes the drive seems to wake back up, but then during the next 15 minutes goes comatose (no power light). Sometimes it will go through multiples of these sleep wake cycles without going into a coma, but eventually it does go into a coma. This happens in between hourly Time Machine backups.
    After locking up Finder, Disk Utility and Time Machine multiple times trying to access the drive in this state I figured out that I could cycle the power switch to regain use of it (with a Finder warning of course) but this will only lead to file corruption eventually and I shouldn't have to resort to this. I've also dismounted it, expecting it to turn off and instead it goes into an extended spin down cycle (rapidly flashing light) and never turns off (or goes to sleep or what ever it's supposed to do) and once again requires turning the power switch off.
    This is just too unpredictible and unrelable for me and as soon as I get the opportunity to do a 7 pass erase I'll be returning to the place of purchase. Based on the reviews of other external hard drives a drive from another company doesn't look to be much better of a prospect so I'm not sure what I'm going to do.

  • MB's optical drive interrupts sleep mode for no apparent reason

    Noticed this over the past few days: When I shut my MacBook's lid, the optical drive spins once or twice and even though the screen is dark, I don't think the MacBook is actually entering sleep mode-- instead, I have hit the "sleep" command from the Apple menu. Each time this happened, there's been no disc in the drive. It happened just now as well. So am I crazy, or is this unusual?
    The MacBook in question is: 2.0ghz Core Duo 2 chip; 120 GB hard drive; 2 GB of RAM; Superdrive. It's a one-month-old black MacBook, if that makes any difference.
    Two nights ago, it happened while the following programs were running [but hidden]: Firefox, Activity Monitor, iChat, iTunes, iCal, iJournal, Mail, LaunchBar, NewsFire, System Profiler, and Pages trial.
    However, this also happened last night and only LaunchBar would have been running at the time. I actually had to turn the MacBook off last night, because I wanted to make absolutely sure the optical drive would stop spinning.
    Right now, the only peripheral "hooked up" to my Mac is a bluetooth-enabled Logitech wireless mouse. Is it possible this is what's preventing the MacBook from staying asleep? I've fiddled with the Bluetooth pane's "allow Bluetooth devices to wake this computer" setting but that doesn't appear to affect when or how often my optical drive interrupts sleep mode. It's annoying when I'm trying to sleep and the optical drive spins up every 30 seconds or so until I have to shut the whole computer off. Any advice would be greatly appreciated.

    Take it in for service since it's in warranty. There may be a serious hardware problem.

  • Keeping hard drive in sleep mode while not in use

    I've got a spare hard drive in my box, which I'm currently using for backups with rsync scheduled to be done once a day via crond. Since it's only used once a day, I figured it would be a good idea to put it into sleep mode by adding `hdparm -Y /dev/sdb` to my backup script. However, I've got a problem with it randomly waking up while opening GTK save dialogs and such. How can I stop it from doing that or make it automatically go into sleep mode after a set amount of time while keeping my root drive awake at all times? And yeah, I know all the downsides of doing that, but noise is the primary issue here.

    You can check laptop-mode-tools for the various tunables they use to optimize disk usage and let it spindown as much as possible.

  • T440 - solid state drives and sleep mode, shutting down, etc.

    First time with a solid state drive.  With my T61, i tend not to actually shut it down unless i really need to.  I just leave it on, close it, and let it go into sleep mode - which i can tell its in because of the moon icon/light.  if i just need to move it around the house, i also only put it in sleep mode.  If I take it somewhere of course I shut it down first.  But that's always a pain, I tend to have multiple browser windows open with many, many tabs.  I just hate having to book mark it all (even using bookmark all tabs) then opening them all up again.
    So, I'm wondering
    1) there doesn't seem to be any light to indicate that its in sleep mode - but maybe it doesn't exist in the same way with a SSD? I was always under the impression that the point of that was to make sure the moving parts of the drive had stopped before you moved the laptop. 
    2) is it still ok for me to just leave it on most of the time like I do with my T61?
    3) Can I get away with not shutting it down when I take it someplace?  Other than the battery running down - why would that be a problem since it doesn't have a spinning hard drive? 
    4) Windows 8, ok this is really a different topic, but I'm here already.  When you shut it down, if for example, you have a bunch of browser windows and tabs open and maybe a couple of word docs - when its started back up, will it automatically open all that?  Or do i have to re-open all the windows, find the word files, etc.?
    5) Anything else I should know about a SSD or windows 8 that is significantly different from what i've had with my T61?  (other than the logo being upside down on the top cover)

    Hi again,
    1. The red dot over the i in ThinkPad will pulse slowly when your machine is in sleep mode.
    2. Yes, absolutely. I use sleep instead of shut down almost exclusively on all machines I use
    on a daily basis.
    3. Same as before, you don't have to worry about doing anything different. The machine won't
    run out of battery during sleep mode for days.
    4. It doesn't matter wether you run Windows 7 or 8, you use your browser settings to set it to
    open the tabs where you left off.
    In Internet Explorer -> Internet Options -> General Tab -> Startup -> Start with tabs from the last session.
    In Chrome -> Settings -> On Start Up - Continue where you left off.
    Same option is available for Firefox too.
    But if you shut your machine down, your programs won't start up automatically with the files you had open
    before shutdown, but I'm sure you meant to say sleep, right? When you resume from sleep, everything you
    had open will be right there.
    5. No, not really. It's just a new generation of a ThinkPad workhorse with a new version of Windows, you
    don't have to change any of your daily routines you've gotten used to.
    Cheers,
    Atli Jarl.

  • Driver issue? with docked T61, and 31P9490- IBM USB Travel Keyboard w/ UltraNav and sleep mode

    Can someone from Lenovo please advise me on which version drivers need to be installed for the external keyboard and mouse, and/or the proper power setting(s) to use with this configuration so the machine will react and wake up from its nap with a Fn+F4 on the external keyboard?
    T61  7658-CTO,  3GB RAM,  Vista Business Ultimate.  These are the external IBM/Lenovo devices used:
    250410U     THINKPAD ADVANCED MINI DOCK
    31P9490    IBM USB TRAVEL KEYBOARD W/ULTRANAV
    31P8700     SCROLLPOINT PRO OPTICAL MOUSE 
    I have an issue with waking my T61 up from sleep mode while it’s docked and using the external keyboard, mouse, and monitor.  When the machine is docked, the blue Fn keys or the Think Vantage button do not function on the external keyboard.
    The external keyboard seems to be the same as the internal keyboard installed in the TP- which I thought would react the same as the internal keyboard when I installed the driver that it came with.  I had hoped something this simple would be easier than it now seems. 
    Thanks in advance! 
    Cheers, Mark

    Thanks for the advice Izzy.  After installing both sets of keyboard and hotkey drivers it does respond to most (but not all) blue Fn key combinations as marked on the external keyboard.  The blue ThinkVantage button still does not respond. 
    Oddly enough, I am able to use the Fn+F4 key combination to put it into sleep mode and to bring it back out, but when the display comes back I have no control of the UltraNav pad, track pointer, or mouse.  I had to open the TP cover slightly and use the pad to get past the login screen to the desktop.
    Incidently, just after using the UltraNav pad on the machine as it was slightly open a couple of messages popped up onscreen involving the USB port(s).  One indicated it was searching for a new device driver for a USB connected device, and the other indicated I could benefit from connecting the device to a high- speed USB port by unpluging the low-speed hub and connecting directly to an available high-speed USB port.
    Interestingly, I don't have any external hub connected. It may have identified the docking station USB ports as low-speed, which I don't believe they are...any ideas for what to do with this new set of issues? 
    Thanks, Mark

  • Since updating to Lion the iMac won't recognise the external hard drive (maxtor) when waking from sleep mode,

    Hi All, Since updating to Lion, my imac won't recognise the ext HDD (Maxtor) when waking from sleep mode, I have tried another port, diisc utility (Ext HDD not listed in here) but nothing works. I now find that I have to restart the imac to get the drive recognised..which is fine until the imac goes into sleep mode then I lose the drive and have to restart etc etc.....anyone suffering same issue.  The Ext Drive worked perfectly until the upgrade..

    Thanks for this, and apologies for delay in replying...in between seeing your post I backed up the ext hdd to another mac and used the disc utility to erase and repair and then re mounted the ext hdd. OK.  I have then tested the ext hdd being recognised when waking from sleep mode a few times and everything appears to be fine. If this doesn't work (long term) I will follow the instructions as you have suggested....
    I now have a new problem with my HP printer (Photosmart Plus) which is not being recognised by a new wireless router..Ok whilst the router is switch on and I have reconfigured the printer..but when the router is switched off overnight and then switched back on...I get a 'printer is not connected' message and have to go through the re configure routine all over. I am minded to think this is a router problem as the same issue is happening to my wifes Mac Book Pro (which is only a few weeks old)...any suggestions..

  • X301 problems after installing driver updates - won't come out of sleep mode

    We have a new X301 with Vista 32 installed. Things were working fine until I ran system update the other day. I've set the power options so not shutdown hibernate, however, after a period of time the system seems to go to sleep or to a screen saver and will not come out of whatever state it is in. The only solution is to power off/on the system.
    I have an X500 where there were display driver problems if there was an external monitor (dual monitor) attached. The only thing I can think of is that either there is some similar issue with the X301 since we have an external monitor attached or there is something that was messed up with the drivers that were installed. I do have (for now) restore points before these drivers were installed but I'm not ready to take that drastic step yet (or a full system restore and start over).
    Anyone experience this type of issue or have any suggestions?
    Thanks
    Neil

    Sadly, I had the issue resurface today. It went into standby/sleep mode while I was in a meeting (on battery power), and later I tried to wake it, and all I got was a black screen with a mouse cursor.
    The keyboard brightness and volume keys on the keyboard were responsive (I could hear the audio level clicks as I changed it), but the visual overlay didn't show (where it shows the white speaker graphic with the bar of rectangles representing volume level). Also, the screen brightness keys did nothing.
    I finally used Ctrl + Cmd + Power to force a restart. Luckily, my user account didn't get completely hosed like it did a couple weeks ago.
    So, it looks like Migration Assistant isn't the culprit here. This is the system I just finished rebuilding. So it's either a bug in OS X/Mavericks, or it's due to an application I have running, or a configuration change I've made.
    It seems to only happen when I'm on battery power, for what that's worth. I don't recall it ever happening when I'm plugged in. I have Power Nap disabled while on battery power, btw.
    I'm going to enable SSH access so I can try to SSH in the next time this happens. Perhaps that will provide useful diagnostic info.
    Anyone have any tips or suggestions?

  • Why is my mac still running it's hard drive and fan in sleep mode?

    Since installing Yosemite my Mac no longer enters proper sleep mode.  Before, the hard drive would spin down and the back would cool.  Now, after updating to Yosemite, the hard drive is still runs, the fan is still runs and the back stays warm in sleep mode.  Surely this isn't sleep mode?

  • My imac takes about eight minutes to be fully functional after a cold start or from the sleep mode. The hard drive sounds like it has to go through a number of gyrations before being fully loaded. When I first bought the imac start up was much faster

    My Imac takes about 8 minutes to be fully functional after a restart or awakened from the sleep mode. I can hear the hard drive making a number of gyrations before it's ready to let me do stuff. This is a 5 year old machine and was much faster in the beginning. Any suggestions?

    Impossible to say however it may need more RAM, or if you have been turning it off every day it isn't given the opportunity to run it's daily, weekly and monthly maintenance. This is all done in the background in the middle of the night. I would recommend following the steps in 25 Ways to Speed Up Your Mac until you find the cause of your slowdown.

  • Why is optical drive running when in sleep mode

    Optical drive appears to be trying to start during sleep mode. It sounds just as it does when MacBook is booted up, this happens continually every few seconds or so in sleep mode. Any ideas? Thanks

    Well of course running cooler is not the main objective, saving power is and heat is dissipated power. Hence if running hot, the main purpose has not been achieved. I don't think Apple or anyone will argue to the contrary.
    As noted earlier, Temperature Monitor.
    Thank you for the link, I had just downloaded iStat Pro which has less detailed reporting.

  • Clicking sound that the iMac hard drive makes every 10 minutes or so when in Sleep Mode.

    My iMac is 2 years old.  I have noticed that when I put it to sleep, the hard drive makes a
    clicking noise every 5-10 minutes.  I had my Lacie hard drive set up for Time Machine, but
    the iMac also seemed to be making the Lacie whir every so many minutes, too.  I have since
    temporariily shut off my Lacie, but the clicking sound persists.  It also seems to me that at
    times the hard drive also is trying to "run" or activate momentarily. 
    I never hear the clicking noise when I am using my iMac.
    I read many posts about other iMac owners having a similar problem.  One "suggestion" was that
    the iMac is not really in sleep mode.  I don't understand that since I use the Sleep prompt under
    the Apple O.S. Icon.  I read somewhere else that the clicking is the cooling of metal, or something
    like that.  That seems a "reach" to me.
    Any suggestions (or directing me to a thread that specifically addresses this issue) would be
    much appreciated.
    In any case, if I need to call Apple Tech (I have 1 year left on my warranty coverage), I would like
    to know if they have probably encountered this problem.  Also, what would be a good way to explain
    the issue, if you can advise me on that.
    Thanks!

    I have since called Apple Support about the problem.  They did not solve it, but did offer to call back.  I was unable to be home for the call back.  I will call them again, but they did not seem to be aware of any "clicking" problems the iMacs were having.
    I timed the clicking noises while the iMac was in Sleep mode; it is every 2 minutes almost consistently. (Not the 5-10 I mentioned in my first post.) Also, it then has a slight "whirring" sound after the "click" or "ping" as if it is trying to process something.
    My iMac does not make the clicking/pinging noise while not in Sleep mode.
    I have searched the Net and these forums repeatedly trying to find someone who has had a similar "clicking" sound.  One fellow suggested his hard drive clicked in Sleep mode because it was looking for a printer.  That is not the problem I am having, since all printer jobs have been completed.
    If any of you could help me on this or direct me to a thread that addresses the issue, I would appreciate it immensely. 
    Thanks.

  • IMac repeatedly corrupting external drive directories in sleep mode

    When putting my iMac into sleep mode or when it goes into sleep mode after a period of inuse I keep getting the "improper eject" message. After waking the iMac I sometimes get the "disc not initialized" message and discover that the directory has been lost. It's happened to 4 different external drives in the space of a month.
    The disks are connected via firewire 800. I have recently added a firewire hub but the problem was happening prior to and post this addition. I can't think of any other changes I've made to my set up that may be causing this behaviour. Previously I've had no problems of this nature in the 2 years since I purchased the iMac.
    The drives run without this problem when connected to my MacBookPro.
    Does anyone have any ideas or suggextions for running any diagnostic tests I coulod run?
    Thanks in advance.

    I have the same issue on my 2011 MBP.  I have three FW800 drives daisy chained together.  The first drive in the series disconnects when my computer goes to sleep and I get the error stating the drive wasn't dismounted properly.  The other two drives stay connected fine.  I don't have to close the lid, it will do this after the computer goes to sleep based on my power saving settings.
    The drive that disconnects is a 500GB G-Drive.  The second drive is a 1 TB Hitachi drive mounted in a IcyDock.  The third drive is a 500GB G-Mini Drive.
    I had the same three drives connected to my previous 2007 MBP and never had the issue.  The issue started when I purchased my new MBP in July.  My software is up to date and I'm use OS X Lion.

  • Why does the hard drive keep spinning up when in sleep mode?

    When my iMac 27" is in sleep mode I have noticed that the hard drive spins up very regularly every 4 or 5 minutes. Also when placed in sleep, the monitor takes about 30 seconds to go black. It also wakes on its own for no apparent reason. No new software has been added, only normal updates, running Lion. Time machine backup is done every couple weeks.

    Power or other problems related to unexpected system sleep, shutdown, lights or fans call for an SMC reset. Read all the steps.
    Before Resetting the SMC
    Try each of the following steps in this order before you reset the SMC. Test the issue after completing each troubleshooting step to determine if the issue still occurs.
    Press Command + Option + Escape to force quit any application that is not responding.
    Put your Mac to sleep by choosing the Apple () menu from the upper-left menu bar and then choosing Sleep. Wake the computer after it has gone to sleep.
    Restart your Mac by choosing the Apple () menu from the upper-left menu bar and then choosing Restart.
    Shut down your Mac by choosing the Apple () menu from the upper-left menu bar and then choosing Shut Down.
    Resetting the SMC for Mac Pro, Intel-based iMac, Intel-based Mac mini, or Intel-based Xserve
    Shut down the computer.
    Unplug the computer's power cord.
    Wait fifteen seconds.
    Attach the computer's power cord.
    Wait five seconds, then press the power button to turn on the computer.
    If the problems persist after performing the above read the following.
    Open the Terminal app - it is in your Mac's Utilities folder and looks like this
    Select the entire line that follows (triple-click to select it), select Edit > Copy, and then Paste it into the Terminal window:
    clear; printf '\e[3J' && echo "**** Sleep/Wake events"; egrep -i 'eep\ cau|ake\ rea' /private/var/log/system.log; echo "**** Assertions"; pmset -g assertions

  • Problems with External Seagate GoFlex Firewire Drive Disconnecting on Sleep Mode

    I am Running a 2.8Ghz Intel Core 2 Duo 24" iMac running Mac OS X 10.7.3. I run time machine to backup to an external Seagate 3TB, FreeAgent GoFlex Desk, FireWire Drive. When the Mac goes into sleep mode, the Seagate drive un-mounts. When the Mac wakes up, I get an error that the drive was not properly disconnected and the drive is no longer mounted. The only way I can get the drive to remount, is to remove power from the drive for several seconds and then reconnect it.
    I have seen several people talking about this issue in various forums with many various makes and models of FireWire drives, but I see no answers to this issue from Apple. Does anyone have a resolution to this issue, or are we just stuck with this problem? It is terribly frustrating!!!! The lack of response or interest from Apple is even more frustrating!!!

    Wish I had an answer, or even a clue about this one. I have a Western Digital MyBook Studio that I've had for a fair number of years now and finally had to resort to just plugging it it as a USB device. Since it's only used for Time Machine backups and storing things I rarely need, it's not a huge burden, but I'd love to hear from anyone with a suggestion as to how to fix this. I recently upgraded from a 17" late 2006 iMac to a Mid 2011 21.5" iMac and would really like to go back to FireWire if it's not going to be a big-ole-pain in the hind end.
