Yoga 8.1 Driver Power State Failure

So this is my second attempt at 8.1 that works as well as 8. Very aggravating but that's old news here. All i can say is that I'd be having a fit except for the one button image of 8 with all my stuff that I just restored.
What causes the suddon Driver Power State Failure message and either freeze or crash? I could have sworn I downloaded all the correct 8.1 drivers and followed all the other suggestions here on this forum.
And, Lenovo, what about providing an 8.1 image for all your loyal cutomers that bought the first generation Yoga. Aren't you embarrased that we are all going thru this?

  • Driver power state failure (Windows 8.1 pro) when downloading a program and restart.

    Hey Guys,
    I've been trying to fix this problem for a while now, without any solution. I have a HP ENVY 15-j035eo Notebook PC (ENERGY STAR)
    which I install Windows 8.1 pro on. I start by getting all the drivers that are missing in Device Manager and updates.
    Now I want to enable virtualization with Hyper -V client (All requirements are met for that). Then the computer crashes after restart with a driver power state failure. Exactly the same occurs when I install Visual Studio after restart. Here is some info from
    the dump file from blue screen viewer that i get for the problem.

    Hi,
    ntoskrnl.exe is known as a kernal image for windows operating system, but hard to find the actual acuse basically according to this error message you provided in the original post, maybe a 3 rd party program or a missing file, or corrupted driver.
    Please uplaod the dump file after running Driver Verifier, you can find detailed instruction in the following link (provided  by Patrick Barker)

    Please help me
    how can i share minidump file. plz let me know.

    We do need the actual DMP file as they contain the only record of the sequence of events leading up to the crash, what drivers were loaded, and what was responsible.  
    We prefer at least 2 DMP files to spot trends and confirm the cause.
    Please follow our instructions for finding and uploading the files we need to help you fix your computer. They can be found here
    If you have any questions about the procedure please ask
    If you are using Blue screen view, who crashed, or a similar application, don't.  They are wrong at least as often as they are correct

  • Driver Power State Failure (BSOD) on Windows 8.1 Pro 64-bit

    How do I solve this? I've attached links to 3 .dmp files as is usually required to spot trends (in fact 3 BSOD's occurred in one day, and I've attached those 3 .dmp files). I've gone through other forums and discussions on this forum, and while others
    had discernible traits for the BSOD, namely things like occurrences after the PC waking up from sleep,etc. For me it occurs quite randomly, during games, browsing the net, etc. and more importantly it occurs very frequently, to the point of at least 1 BSOD
    a day. My GPU drivers are up to date and I don't think it's because of that. Hope you guys can help me out...

    These were related to your nvidia driver.  There is a known issue with the current driver (yours) on some systems.  As a work around I would install an older driver (at least 6 months older) until a less buggy driver is released.

  • Symptom preceding my Time Capsule Power On Failure: Apple TV2 Glitches

    Hope this helps someone. I spent days re-installing the system on my my Mac Mini and re-updating my Apple TV 2 firmware in an attempt to solve the problem with my AppleTV2 and Mac Mini losing connection with each other, before the Power On Failure of my Time Capsule identified the problem was elsewhere.
    For a month preceding my Time Capsule Power On failure (see below), my wirelessly-attached Apple TV Gen2 would stop in mid-stream while playing a playlist from my wirelessly-attached Mac Mini. Nothing short of quitting & restarting iTunes on the Mac Mini would re-establish a connection.
    But when my Time Capsule failed and I was forced to substitute an old AirportExpress b/g base station, all the problems with the AppleTV2 losing connection to the Mac Mini disappeared!
    It seems that prior to my Time Capsule failing completely FAILING it was exhibiting MINOR glitches in its wireless operation. These glitches were NOT sufficient to drop the Mac Mini or AppleTV2 from the Internet, but they were apparently enough to interfere with Bonjour networking between the two devices.
    BACKGROUND
    My single radio, 1TB Time Capsule failed Wednesday night, pretty much textbook as per the 1100+ replies on this thread: Time Capsule Powered Off, Won't Power Back On: http://discussions.apple.com/thread.jspa?threadID=2129872
    My particular "Time Capsule Power On" failure symptoms:
    - Time Capsule WiFi network disappeared
    - Time Capsule the indicator light was OFF (rather than normal green, or even a flashing yellow)
    - Power cycling Time Capsule initially would result in yellow light for 10-20 seconds then nothing
    - With hand on the Time Capsule case I could feel the internal hard-drive spinning
    - Within 1/2 hour, repeated power-cycling would result in the light NEVER coming on
    - Serial no. as per http://support.apple.com/kb/TS3351 Time Capsule: Does not power on
    The local Apple store Genius bar replaced my Time Capsule with a brown box 1TB, single radio unit, but would NOT transfer my data on my old Time Capsule. When I asked for assurance that my data would be erased, they said that it was Apple policy that all returned drives are destroyed. It was accept that unwritten promise or leave with my broken Time Capsule. I was NOT happy, but life is already too short – I accepted the replacement Time Capsule.

    Contact a repairer in your area.. we can fix them cheaper than data recovery.. and you will get a working TC back as good as new.. in fact we can make it better than new because we can fix the fundamental flaw .. no cooling.

  • Ipw3945: power/state file missing!

    hello!
    after upgrading to the new 2.6.19 kernel-suspend2 and the new ipw3945-suspend2-1.1.2 driver i can't switch the power-states of the interface, because the file /sys/class/net/wlan/device/power/state is missing!
    so, how can i change the states from now on or is this a bug?

    no, iwconfig power is not for that!

  • Echo disk /sys/power/state broken

    Hello all
    After recent update after long time my hibernate was broken
    #echo disk > /sys/power/state
    does black screen and standby of display later. But system block not turned off, e.g. fans are worked.
    #echo mem > /sys/power/state
    is working. Before update echo mem not worked right
    #cat > /sys/power/state
    freeze mem disk
    Install old kernel not resolve the problem.
    I try to do debugging hibernation with https://www.kernel.org/doc/Documentatio … ugging.txt
    echo freezer > /sys/power/pm_test
    echo disk > /sys/power/state
    worked
    but
    echo devices > /sys/power/pm_test
    echo disk > /sys/power/state
    not worked
    If the "devices" test fails, most likely there is a driver that cannot suspend
    or resume its device
    Who can broke hibernation process?

  • Hard Drive detects imminent failure

    Please can anyone help. i have a compaq 6735s lap top which is about  months ols. Today when i switch on I have a black screen with the following message: 1720-SMART hard drive detects imminent failure.
    What should i do now

    Hi,
    How many months?
    The error message might or might not be true. It is worth your time to go ahead and back up all of your data to an external hard disk
    Boot into Windows and go to Device manager look at the disk drive device click on the + to expand the category and post the model number (the complete alphanumeric string next to the icon)  here in your thread. There is a possibility that your hard drive requires a firmware update. I will do a bit of research to see if that is indeed the issue.
    There are some Maxtor drives that have had to have the update done to correct the SMART reporting feature which caused an error message virtually identical to the one you are getting.
    regards,
    erico.

  • Hard drive short DST failure

    hard drive short DST failure code PGFTHS-00079L-60R303 DO i NEED TO REPLACE HARD DRIVE?
    This question was solved.
    View Solution.

    Hi,
    Yes, the 24 character error code for the Disk Self Test ( DST) would indicate that the Hard Drive is failing and needs to be replaced.
    If you are is still under warranty, contact HP and arrange to have the drive replaced - you can check your warranty status Here.
    If you live in the US, contact HP Here.
    If you are in another part of the world, start Here.
    If you are out of warranty and would like a guide on replacing the Hard Drive yourself, please let me know.

  • Yet another Nano 6th Gen with power button failure

    When is apple going to put its hand up and admit there is a problem with the 6th Gen Nano. My daughters 13 month old 16gig  ipod has a power button failure the same as so many others. At £120 odd its already an expensive bit of kit without having to purchase an extended warranty. Pay another £50 for a repair and another years use? I dont think so.
    I notice the sales pitch  boasts the new ipod has been "completely renanoed"  Come on Apple why dont you look after the little people and give us a decent trade in on these faulty year old ipods against a new sorted one? Patrick

    Well a robust defence of your product Apple well done!

  • Pm-utils-1.4.0-1: aggressive hard drive power saving (often spin-up)

    [sorry, misplaced post. this issue is for package from extra repo]
    Hi all,
    after upgrading from pm-utils-1.3.0-2 to pm-utils-1.4.0-1 I noticed that hard drive on my laptop is stopped and spinned up again too often.
    The reason for this is script introduced in pm-utils-1.4 /usr/lib/pm-utils/power.d/harddrive that activates aggressive power saving. pm-powersafe is triggered after suspend wake-up in my case.
    I noticed that
    # hdparm -B /dev/sda
    /dev/sda:
    APM_level = 1
    in case when laptop runs on battery power, and
    APM_level = 254
    when on AC. And I'm rarely use AC
    Positive effect of this aggressive hard drive power saving is really doubtful as it can shorten your hard drive life significantly and cause apps hung till spin up very often.
    I don't want to bring up a big discussion here, almost the same problem was discussed by ubuntu community
    "Ubuntu's Laptop Killing Bug":
    http://it.slashdot.org/article.pl?sid=0 … 4&from=rss
    Currently I manually disabled power saving on hard drive by
    # hdparm -B 255 /dev/sda
    /dev/sda:
    setting Advanced Power Management level to disabled
    APM_level = off
    and disabled /ur/lib/pm-utils/power.d/harddrive by resetting execution flag.
    I monitored spin up cycles count by
    # smartctl -a /dev/sda | grep Start_Stop_Count
    4 Start_Stop_Count 0x0032 100 100 000 Old_age Always - 4715
    It grew significantly before I noticed the problem

    I have
    hdparm -B 255 /dev/sda
    in /etc/rc.local to apply this after boot and
    #!/bin/sh
    # Use a less aggressiv hard disk power management in order to get
    # rid of clicking noise which occurs when the drive is parking its heads
    . "${PM_FUNCTIONS}"
    case "$1" in
    thaw|resume)
    hdparm -B 255 /dev/sda
    esac
    exit $NA
    in /etc/pm/sleep.d/00-hdd to apply it after resume from suspend, but when resuming APM is not set since recent version of pm-utils

  • How to change power state in a Service Profile Template

    I'd like to change the setting "Power State" in a Service Profile Template. While I can change nearly every other aspect of the template, I can't find this in the UCS Manager GUI. Is this an immutable decision while creating the template? Can I change it via the CLI?

    Hi Joernclausen,
    What is the firmware version of your UCS?
    From the CLI try the following and let me know if it works.
    Go into the FI CLI and perform the steps below, ensure to enter your own template_name and select appropriate type of template followed by setting the power up or down
    sj-ucs-r13-mon-A# scope org
    sj-ucs-r13-mon-A /org # enter service-profile template_name initial-template
    sj-ucs-r13-mon-A /org/service-profile # power up
    sj-ucs-r13-mon-A /org/service-profile* # commit-buffer
    sj-ucs-r13-mon-A /org/service-profile # power down
    sj-ucs-r13-mon-A /org/service-profile* # commit-buffer
    You may also be able to change the power state from the individual service profiles
    Go to the service profile and use "Change Initial Power State" button for modifying the desired-power value.
    see attached screenshot

  • IPhone 4s power button failure

    My power button has completely failed and unresponsive. Cannot put on standby, turn off or reboot. Has anyone else got this?
    I'm going to a genius bar next week as its still in warranty.

    I had a power button failur on my iPhone 4 which is presumably more or less identical with regards to the power button. They had to replace the phone as they can only repaire the back glass. Take it back to the Genius Bar if possible.
    My friends just had theirs swopped out with few questions asked, as it's not deemed serviable.
    Mine was 14 months old so out of warranty - 199 euros was the fee

  • Time Capsule power supply failures

    Has the chronic Time Capsule power supply failure after about 18 months use been fixed in the new Time Capsules being sold today?  I had a 500GB Time Capsule I recently had to scrap because of this.

    It is always possible there is another fault.. to shut down after a minute.. if you are relating that correctly.. is unusual.. I would power the board from 5v 2A supply.. that will quickly show if the issue is your power supply or not.
    The TC is definitely in need of more cooling but I would hate to suggest doing a major modification until it runs out of warranty. It is possible to improve the existing cooling with a bit of smarts.. a laptop (or netbook size) cooler to which you can seal the TC.. this is the tricky bit.. you need to allow a space underneath though.. perhaps 10mm.. and seal just the edge of the TC so it allows the cooler to draw air through the TC. That will work without modifying it. But you will need to make up a proper spacer and gasket.
    I see pictures of various fans mounted on the top.. they are next to useless. Cooling the outside plastic will achieve only the tiniest improvement in heat transfer due to the thick plastic (insulating) top.. if it was made out of metal maybe it would do something.
    Sounds like what is also needed is a different heat sensor that would start the fan at a lower temperature.
    It is not the sensor that is the issue. The TC includes a proper fan controller. It is simply set too high.. and so it doesn't turn on.
    If you want to break into the TC.. you can solder in a console.. and use serial to USB adapter.. these are very cheap.. the soldering in is tricky.
    See the bottom of this page.
    http://sites.google.com/site/lapastenague/a-deconstruction-of-routers-and-modems /apple-time-capsule-repair/new-issue-with-a1355-gen-3-tc
    The envstat.. will show temp.
    This command will turn on the fan.
