Computer fate of mode standby on its own at different times

Why my computer was out of fashion "sleep" on its own at different times?  Should I worry about malware?  I looked in the Task Manager for the CPU usage and the number of processes running, but I don't know what to look for.  There is a current version of Kaspersky Anti-virus running that updates automatically several times a day, but I do not believe that he "wakes" the computer.  Don't think that Windows Update for this either.  The power fluctuations cause this?

1 in a command prompt, enter

powercfg - lastwake

to see which woke up the PC to the top of the last time it happened.

2 you should also watch inTask Planner to see if you can match time following the time of the task.  You will need enable all tasks history.

  • Dell Dimension E521 starts and stops on its own at random times... a lot of attempts to repair/restore without success! What's next!

    Well, it's a bit of a long story, so I'll try to make it as short and easy as possible.

    My grandmother had the Dell Dimension E521 for some time in December of ' 06.  She had filled the C: drive with a bunch of junk and mandated the bureau with many useless shortcuts.  Later in November 10, she told me he had begun to stop and start on his own time at random, so I tried to do what I could with antivirus scan (AVG Free Edition), remove applications and unnecessary programs and try to demand for system recovery short.  While that makes the computer run faster, it still started and closed on itself.  His house has only the dial-up connection (which is almost impossible to update anything), so I brought it to my house for the best connection around 01/01/11 (9 days ago).

    I could update the AVG Free Edition and Windows updates, and it found and cleared, a Trojan Virus.  The Dell still started and shut down on its own.  My next step was to use the disc re - install for Vista Home Basic 32-bit.  He old programs saved in a folder "Windows.old" on the C: drive and completely re-installed everything back to the original.  After I checked in the "Windows.old" folder and recorded something she didn't lose (such as images and videos), I deleted as much as I could out of it.  The only thing I could not remove from it was 4 'driver files '.  For a while the computer trying to run 'chkdsk' on its own seizure began, but froze in the middle of it.  He finally ended the 'chkdsk' once and didn't try again since.  It downloaded and installed updates Windows of 100 or more on its own as well.

    After all, it still does the same thing he has with housing starts and shut downs.  The closure of downs occur not just in the middle of the execution of a given program; they occur at any time at random, even if I use the computer in safe mode.  She always goes through the whole stops the process with the "logging off" and "closing" legends, it is not as if the electric system is down.  The start-up occur randomly as well, even if a stop is purposely through the Start Menu or hold down the power button.  Sometimes, he's trying to start and shut down on its own several times without fully load.

    Again, sorry this is so long, but I would like to know if there is anything that can be done to get this thing to CUT IT OUT because my grandmother wants as his computer back!

  • my laptop stops on its own

    recently, I downloaded some games from mostfun.com and everything was perfect for about a week, then my computer just started blocking down on its own and incidentally I don't get error down and all just poof, he's going he first flicker a small last thing so far it's just when I know im running one of the games or a movie I downloaded the logical thing in East to remove these i I want to just make sure that its not something else

    It seems that the laptop may be overheating.  Are you sure there is enough air past for laptop?  Make sure that it is on a flat surface, with nothing to obstruct the ventilation openings.  Make sure that the vents and fans and heat sinks are free from dust - examine their blowing with compressed air (power of the system first, of course).  Depending on the laptop model, it may be relatively easy to blow off the dust with compressed air, or otherwise clean up things a bit.   Fans should be kept up well - only no right turn when being ripped off.  My Dell laptop has a removable fan (two small screws need to be removed) that can easily be blown.  This also allows access to the fins of the heatsink.

    Some laptops also have a removable filter that traps the dust and must be regularly inspected and cleaned.

    Are all the BIOS settings for the adjustment of the temperature, the value lower than the manufacturer's recommendations and the default values (you need to check the manual of your laptop for this).  Also make sure you run the latest version of BIOS (again, the manual of your laptop would have the details; the manufacturer's website should also have this information).

  • Since iOS 9.3.1 my phone plays music on its own when the headphones are connected

    Since the last update, my battery does not last a whole day more and for some strange reason when my headphones are plugged into the music start playing without me from music. Music plays on its own at random times. Several times when I have my phone on the desk, I heard the beginning of music playing also on its own that helps the battery drain but other that the battery for some reason life any has been terrible. I hope Apple fixes this soon and also the restoration of the ability to use 3G to help save battery life. I have actually charged my battery to 100% and without touching all day insured no apps running in the background and I noticed my battery was 70% when ended the half-day.

    Try settings-> general-> transfer & Apps suggested and disable "Apps install".

  • Watch going in silent mode on its own

    Sometimes--not always, but often enough to be annoying - my Apple Watch goes into silent mode "on its own initiative.  I have NOT used the application settings or wink to do this, my iPhone is NOT cut, so it's a bit mysterious.

    Hi Doug

    You probably accidentally placed your watch in silent Mode using the cover for the Mute function.

    Cover for Mute is a feature that automatically places your watch in silent Mode if the display is covered for 3 seconds immediately after receiving a notification alert (for example, for a text message). When the quiet Mode is enabled in this way, haptic feedback is provided as confirmation. The mode must be disabled manually in order to reactivate the sound alerts.

    To turn off the Mute function coverage:

    -On your iPhone, in the application of Eve, go to: Watch My > sounds & Haptics > turn it off coverage on mute.

    More information:

    Adjust the brightness, text, sound and haptic on Apple Watch - Apple Support

  • Everyone knows the watch switch silent mode to its own?

    I noticed that my Apple Watch going in silent mode on its own. Anyone experience this problem? I want a software update with a small icon on the top when the watch is in silent Mode. Any thoughts?

    Yes, mine did so a couple of times. Did not with 2.1 so far.

  • So dead computer battery died. Why the computer is not put in Hibernate or stop safely on its own?

    It must be a problem with Vista. When my computer battery runs out, my computer dies. Why is it not computer smart enough to know the battery died about to close?  When I used XP, the computer would Hibernate protection itself. With Vista, I get a warning that the battery is almost dead, but most of the time I don't get any warnings, the matrices of the computer. Because he died, when I restart the computer, 9 of 10 times I get an error message and several varying options to start in safe mode to start normally.  The other tenth, the computer takes about 20 minutes to get back to normal, sometimes I even to restore the computer to a previous backup. Its been getting worse lately, these last 2 months. When the computer was new 1.8 years ago, I never had to restore when the computer was turned off.
    From the beginning, I returned the computer to bridge and when I came back, they did something that until now I know.  The computer is always went cold Turkey when the battery was missing. Recently, I thought of the situation and realized that it wasn't a gateway problem but a problem with the operating system.

    I'm wrong, it of a Vista problem and shouldn't the computer hibernate or sleep instead of just trying to die and lose everything?

    Make sure that your power options are set correctly:

    Place your mouse over the the battery icon on the taskbar and right click.
    Select "Power Options".

    According to the plan used on your computer, click on "Change Plan settings".

    Click on "change power avancΘs."

    Scroll down and expand the entry for the battery.
    Expand "critical battery Action.
    Make sure it is set to Hibernate or sleep, you like (Hibernate allows you to Exchange batteries without data loss).
    Expand "Critical battery level" and set the battery level at which this action take place (5-7% usually leaves enough power to go in hibernation).

    Click on 'Ok '.
    Once the laptop goes into hibernation, not to interrupt the process by removing the battery until the light on the hard drive and all the other lights stop flashing and power down. Once they have fed completely down (may take a few minutes) you can exchange the batteries safely. To wake up from hibernation, press and release the power (once) button. Function of various factors, your laptop can take 1 to 5 minutes to return to the login screen, although usually, it will be one or two minutes, not five.
    Please let us know if this is not the problem.
