Malfunction of Power Options

I have an off dysfunction with an option setting to change. I set my screen to never stop, but it spontaneously returns to the default setting of 15 minutes without any apparent reason showing. He did this more often with time, which occur almost daily now. There is no model when the display turns off, so I don't know when the parameter returns. I ran sfc/scannow with nothing found, and I ran 2016 Bitdefender internet security and Malwarebytes didn't find anything. Someone out there have any ideas why this might be happening and what I could try before reinstalling windows 7? It almost seems as if there is a corrupted file or malware as possible at the origin of this, but so far I found nothing and I'm not all that computer so I've pretty much exhausted my meager resources.

Hi Dave,.

Thank you for the update.

  • NB200 122 - loading using the battery power options

    Dear all

    I recently bought a Toshiba NB 200-122 Mini Netbook, I tried to use all the power options (full power)... always shows 15% battery (charge) even if I kept it charging for a day in hibernation mode... (when connected to the power unit).

    Other laptops would be fully load 100% when it is connected to the unit of power for one day...

    Why the netbook battery is slow or not clean load?...
    Or other options with her... Or having to drain the battery completely and use it...

    Could someone suggest me some advice about this...

    Thank you

    regards Sarah

    Hi Sarah,.

    I agree with the user above. You should try a BIOS update you can find the Toshiba site. Before applying it, close all programs running also your antivirus and firewall and make sure that you are logged on as administrator.

    In the worst case you battery is damaged or some cells in it. You can get a spare to an authorized service provider.

  • Satellite P10 804: Toshiba Power Options - how to disable Hibernation

    Model SP10 - 804

    How to turn off the Hibernation feature?

    The 'Enable Hibernation' box is checked and grayed out so I can't uncheck it!
    I don't use this feature and would like to delete the hiberfil.sys file that is beyond 1 GB.

    I understand that by disabling the hibernation, this file should remove. I read about it here:
    http://www.softwarepatch.com/tips/Hiberfil-sys-XP.html

    Thanks in advance.

    Hello

    I presume that the Toshiba Power saver utility has been installed on your system.
    In this case, the windows own power options are disabled and the TPS control the hibernation and the day before.

    You can switch to the mode of power window in Control Panel-> power options control.
    Here, you have to choose to another scheme of power as the Toshiba power saver.
    Otherwise, you can remove the GST from the system!

    However, in my opinion the hiberfil.sys has no bad influence on the system and it is really not necessary to delete that file.
    On my system, the file size was never 1 GB.

  • Sleep icon does not appear in the power options

    I just closed the lid of my Lenovo ThinkPad T460s only once but since then I can't see "sleep" icon under options of 'power' to the main screen. How can I see the icon of sleep again?

    Hello

    The reason why sleep does not appear in the power options is your Intel graphics card.

    Please try to disable Intel graphics in the Device Manager and turn it back on.

    If it still shows yellow bang, try to download the latest Intel graphics driver from Lenovo site.

    I hope this information helps.

  • Power options in the control panel are empty - can't do anything.

    Recently, I noticed that the Power Options in the control panel is empty.  I can't create something or do something there.  Could something in Services.msc have disabled this?  Nowhere part that I should look at?  I cannot stop, restart, or put it to sleep.  Also when I start the computer (once using the hardware Reset button on the computer case) he does not remember my user name.  He asks me every time.  There is no password.  I just press ENTER after entering my user name.

    So I found the magic formula to use the command run and it resets everything back to normal.  Can't find it now but if you google it you can find.  You want to reset the Power Options in the control panel.

    His time, I have contributed something here!  I'm always ask questions and rarely give all the answers.  :)

  • Hibernate tab missing in Control Panel - Power Options

    Using Windows XP with SP3, Dell Optiplex 320.  I know that material can hibernate.  How can I determine the cause of the hibernation tab in Control Panel - Power Options

    I run SFC.exe to find broken windows files.  I don't know where to look for a log of the results.

    Meet the same on Dell Latitude E6330.

    Installed with Windows XP SP3.

    Reinstall the display driver card solved the problem.

  • I can't control the sleep display option - display decreasing intensity 5 minutes despite Power Options

    I have a HP Pavilion dv7, running Win 7 Professional SP1 x 64. It was purchased in 2010.

    The display dims (goes to dark blue, not black, the desktop is not visible) after 5 minutes of inactivity.

    The cover of the computer is open, pc is connected, nothing else is running.

    I have power Options (Control Panel--> equipment) and its--> power for trendy Options value

    HP recommended and I have edited the plan to these settings:

    • The brightness... 20 minutes
    • Turn off the display... 45 minutes
    • Put the computer to sleep... 1 hour

    I put these time abnormally high just to see if the system will follow this plan, and it's not.

    Which bothers me more that gradation display after 5 minutes.

    Are there other system options that replace power options?

    Please point me in the right direction.

    Thanks in advance for your time and help.

    Your blue gradation display can show it's a flavor of screen running.

    Check it out and set it to none.

  • Aspire 5742 not allowing changes to power options

    I'm changing Power Options to never sleep or Hibernate, but as far as I have to change the settings is not to do it.  I have upgraded to Windows 10.  Any help would be appreciated.  Thank you

    Felicity

    Hi Felicity,

    I make a few assumptions, but you can go into advanced settings and turn off some other things like putting to sleep HARD drive. From there on, make sure that both your battery and plugged on options are set correctly.

    Finally, maybe a screenshot of the issue would help others contribute more to your question.

    Thank you

  • Unable to use power options icon of in Control Panel (xp)

    My friend has an Acer laptop running on Windows XP. However, after clicking on the 'power options' icon in the Control Panel, it does nothing. That's happened? I can manually download and reinstall something rather than having to perform a system restore? My friend was not aware that this icon does not work and therefore doesn't know how long it has been like that.

    Hello Azam K,.

    My apologies for my delay in responding but I've been away for a few days. Thank you for the feedback. However, so far I have not need make your suggestions because I managed to find a download on the Acer site for an Acer ePower Management application which seems to be what the power options icon was eager point to (I hope that makes sense?). The original Acer ePower Management software seems to be on the laptop but has been altered.

    Once again, thanks a lot for your feedback.

    Kind regards

    Stuart.

  • Power settings have changed and I can not open my power options.

    I can't open my power options, and my laptop is somehow set to the screen to get dark every 2 minutes, even if I never got him to do. I tried opening the Control Panel, screen saver properties and the run menu. She will act as it starts to load for about 2 or 3 seconds then I get nothing. I really need to solve this problem, because my husband is deployed and it is difficult for my 2 year old to sit and have a video conversation with him. Thank you!
