Updates Secretly Changing Power Settings

I've been suffering with weird pc symptoms, including frequent freezeups for about a month.  And I noticed my pc would dim and I thought it was the video driver's software.  And all this time, never thought to check my power settings because I had already set them to my own happy tweaking. 
So after tons of research on why it's been freezing up frequently, and all these problems, someone suggested I change my power settings.  And I was like, well, it can't be that because I already have it set.  Checked the power settings anyway, and there it was, some update had secretly reset my power settings all to low.  Soon as I put them all back to high performance, the monitor was brighter again, pc is running smoothly again. 
So I thought I'd post this, if you have weird problems after updates, check your power settings.  Some updates, and I have no clue which ones, will secretly reset your power settings on you.
It's still too early to tell if my freezeups are fixed by this, but so far, I haven't had one since resetting the power.

dammit! any way to get that feature back?

  • Tecra A3 does not work after changing power settings

    I changed my power settings in my tecra a3 laptop and now it won't start properly. wants to start but just keeps going back to press F2 or F12 please help.

    Hi,
    where did you changed them? In the BIOS or in the Toshiba HW-setup?
    I would suggest you to go to the bios after powering up your machine. You must just hit F2 ant then in the bios search for the setting "setting everything to default" or something with "bios setup defaults" to reset your bios settings.
    After that your machine should boot up again.

  • How to change power settings?

    My G series Windows 8, 64-bit laptop keeps going to sleep after about 2 minutes while plugged in.  I changed the power settings via Windows 8 (by personalizing desktop and / or clicking on battery).  But it still keeps happening.  Is there another setting I need to change specific to Lenovo?  It's annoying as all get out, and frankly a little ridiclous I need to waste time tracking this down.
    Thank you.

    There are a couple of free utilities that purport to intercept the power key, but neither of them work for me with Mavericks and a 15" Retina MacBook Pro:
    PowerKey
    PowerBlock – I thought it might work with Mavericks contrary to what the site says because someone posted in another forum implying that it works with Mavericks.
    AFAIK, Keyboard System Preferences cannot change the keyboard shortcut for the power key.
    It'd be great if Apple gave us a way to prevent accidental Sleep, which can be a killer when doing something mission critical. I'm pondering removing the physical key altogether…

  • Changing power settings from the battery indicator

    i was wandering how to get the setting where you can change the battery settings (better energy savings, normal, better performance, custom) from the battery indicator at the top in the menu bar.
    i could do this before where i would click on the battery indicator, under the drop down menu, i could click on any one of then options. but now those options are not there. i can only change the settings by going into system preferences.
    cheers.

  • Why is my account no longer valid for the Aust. Store.  The update has changed my settings.  How do I change them back?, Why is my account no longer valid for the Aust. Store.  The update has changed my settings.  How do I change them back?

    I bought my iPad in Canada and have been happily updating my apps until I accepted the latest upgrade.  My iPad now tells me my account is not valid for use in a US store.  I must switch to an Australian store.  How do I do that? As I am Australian and going home soon I am happy to do that but am wondering why it has changed.  Not happy

  • Calendar last emailed reminders 12th June - suddenly stopped doing that, but I haven't changed any settings.

    Windows Vista Home basic - Firefox 4.01. I use Calendar to remind me of my work schedule by email. Suddenly stopped notifications after 12/6/11. As far as I can see I have not downloaded any updates, nor changed any settings/preferences either in Windows or Firefox. Help please. Thanks in advance.

    I have the same issue. It began with my 3GS some time around september-october I believe. I purchased an iPhone 4 in November and it does the exact same thing. I did restore my iPhone 4 to a backup from my 3GS when I got it. I have the latest versions of iTunes/iOS. Ok now my iTunes library is on my laptop with 32-bit Windows 7 Pro. I have moved my library from a machine running 32-bit windows xp pro to the laptop running 32-bit windows 7 pro. So I'm wondering if possibly either restoring from a backup, or moving my library has had anything to do with it. Just trying to figure this out...
    Apple. ***!?!? Get on this. I am an avid podcast listener and I sync daily to keep my podcasts fresh. I already have to physically connect my iPhone to the computer because iOS doesn't support wireless syncing. But now on top of that I have to hit cancel or apply after EVERY TIME I sync my iPhone. Not the biggest deal in the world. But a huge inconvenience and annoyance. Apple usually prides themselves on the fact that their products "just work". Well Apple, my iPhone 4 DOES NOT "just work".

  • I wrongly changed my settings to the American store and now when I try to download updates for the apps my ipad 2 tells me I need to switch back to the Canadian store, how do I do that. Resident of Canada

    I wrongly changed the settings on the apps page to the American store. Now I cannot download any updates because I am locked out and need to revert back to the Canadian store, how do I do that

    Try going to the bottom of the Featured tab in the App Store app on your iPad and tap on your account id, tap on 'View Apple ID' on the popup and log into your account, and then select the Country/Region section and select Canada.

  • When Updating to IOS4 Do Not Say Yes to Udpate Changes to Settings

    I updated my iPhone 3g to IOS4 on release date. OK You can stop laughing at me know, I got screwed over but I was lucky.
    I couldn't get the OS to install using the update so I did the work around and downloaded the OS into iTunes and did a backup and then a restore. I had read a couple of threads that said this would work a lot faster than doing the update. I had waited nearly three hours for the update to finish so I figured it was the combination of my creaky old PC, iTunes and one of the apps on my phone so I tried the restore instead of update trick. It actually worked and only took about 30 minutes start to finish.
    BUT when it was done I got a dialog box telling me that I had changed my settings and did I want to apply this change to my phone <YES> or <NO>? Without thinking about it I clicked yes and my phone did another sync. I lost my address book, email and text messages all in one fell swoop. Can you spell panic and nausea? I thought you could.
    I was all over the web looking for ways to restore my stuff. I tried another sync because the last one I did before installing the new OS should have still been there...No Luck.
    I tried everything I could think of and nothing worked. I wasn't too worried about my email, because of course it was still out on the web (Gmail Rocks!!)
    Then it occurred to me, I had been using Gmail and GSync. I set up a new G-Sync account on my phone and set it to running. It took about 24 hours total, but all of my email, contacts and text messages restored themselves to my phone wirelessly.
    So I strongly recommend that you do not apply changes to your phone when you do the IOS4 update. At least not the first time around. I also do not recommend using the restore in place of update workaround. Just let the update run (and run and run and run and, well you get it)until it finishes. You should get a clean install and a total restore of your music, contacts, apps, email, etc. I have no idea why an update on an 8 Gb iPhone needs to take hours, but apparently it just does.
    So to sum up:
    If updating to IOS4 use the update in iTunes not restore
    At the end of the update DO NOT apply changes to settings
    DO use gmail and G-Sync or another email that backs up your address book to the web.

    Fixed it......
    The problem was my Apps library in iTunes was not populated with the apps on my phone after the update of iTunes and iOS4. Therefore, that is why I "lost" them visually. Now, had I gone and hit "Apply" I would have been screwed, since nothing was in my iTunes App library.....Sneaky.....
    In iTunes, File>"Transfer Purchases from iPhone"
    This populates the iTunes App library with the apps on your device. It will take a few minutes, but all of the apps will now show up when you go back and try to sync the iPhone.

  • HT1688 Someone changed the settings on my iPhone so that I can no longer update my apps or download new apps. I don't have the icon on my phone anymore. Can someone please tell me how to get it back?

    Someone changed the settings on my iPhone so that I can no longer update or add apps. The icon no longer appears. Can someone please tell me how to add that back?

    I should have added that the iTunes app is not displayed on my phone in order for me to add the apps.

  • Updated latest version of itunes onto windows xp.Can't open it.The Data Execution Prevention window comes up.I have followed all the directions of changing the settings.I have updated Quicktime.Still can't open it.

    I updated the latest version of itunes onto my pc (windows xp) and all of a sudden I can't open it up.  Everytime I try to open it I get a window that says: "Data Execution Prevention - Microsoft Windows...To help protect your computer, Windows has closed this program.  Change settings."  I have tried to change the settings.  Uninstalled & reinstalled itunes.  Updated the lates version of quicktime.  Nothing has helped.  If there is anyone who has a suggestion I would appreciate it.  I am at my wits end with this.  Thank you in advance for all your suggestions.

    If anyone is looking at this and would like to know what I did to finally get it to work, I did the following:  I right click on the itunes icon on my desktop.......clicked on "run as"........made sure that it ran as administrator.   This finally worked for me.  Hope you all find this info helpful.

  • How to change sequence settings without CC 7.1 update?

    Well, i was hoping that Adobe will release 7.1 update on October 15th, as promised on some websites. I don't recall, maybe it was Creative COW or any other.
    That's why i have created 720p PRORES proxies for 9x multi-camera live performance shoot which lasts for 2 hours for lag free, fast editing.
    I have sucessfully edited it and promised my clients that on October 16th they will get the whole show in 1080p, high quality.
    So, there is no update yet, and yes, i can relink files to original 1080p, but the multicam sequence is capped to 720p and i simply can't find a way to change it's size.
    The old fashion copy/paste way from one sequence to another does not work, since 720p sequence is linked to multicam edits. In CS6 i could edit ".prproj" file in text editor to change any properties (including sequence properties), but right now in CC, .prproj file contains binary data only, so i can't do it that way either.
    Maybe someone knows any other way to change sequence settings right now, or what is the exact day for 7.1 release?
    Thank you!

    Hi Paolon!
    You need to extract your .prproj using WinRAR to a text .prproj file, then use some text editor such as Notepad to search and replace sequence dimensions
    For example find "1920" and replace it to "1280" if it looks like Īt belongs to a sequence definition.
    I don't recall how it was called, maybe "VideoFrameRect" or something similar.
    First create some very simple project to experiment with, and always make a backup copy in case something goes wrong

  • I just updated to 5.7 and the exported files are blurry. I compared the ones I exported before the change and they are fine. I have not change any settings.

    I don't understand your last paragraph.
    "The home page also has a full bar ..." What does "full bar" mean? " ... instead of the tray it had before."  What does "tray" mean?
    Anyway, you might try Settings > General > Reset > Reset Home Screen Layout
    I guess that cannot make things any worse.

  • I updated the kmp player a few days before. It changes some settings on my firefox

    I updated the kmp player a few days before. I believe that It changes some settings on my firefox or more.
    It changed my home page. Also, every time I reopen firefox, it cannot show my windows and tabs from last time.
    Then I removed or stopped using the plug-ins in firefox (one of them is npAPI) that installed that day, changed the setting back to what I want.
    I can then get the home page back, but the problem that I cannot get my previous tabs when I open firefox back still exists.
    I have updated firefox to 25.0 today.

    Hello,
    '''Try Firefox Safe Mode''' to see if the problem goes away. Safe Mode is a troubleshooting mode, which disables most add-ons.
    ''(If you're not using it, switch to the Default theme.)''
    * On Windows you can open Firefox 4.0+ in Safe Mode by holding the '''Shift''' key when you open the Firefox desktop or Start menu shortcut.
    * On Mac you can open Firefox 4.0+ in Safe Mode by holding the '''option''' key while starting Firefox.
    * On Linux you can open Firefox 4.0+ in Safe Mode by quitting Firefox and then going to your Terminal and running: firefox -safe-mode (you may need to specify the Firefox installation path e.g. /usr/lib/firefox)
    * Or open the Help menu and click on the '''Restart with Add-ons Disabled...''' menu item while Firefox is running.
    [[Image:FirefoxSafeMode|width=520]]
    ''Once you get the pop-up, just select "'Start in Safe Mode"''
    [[Image:Safe Mode Fx 15 - Win]]
    '''''If the issue is not present in Firefox Safe Mode''''', your problem is probably caused by an extension, and you need to figure out which one. Please follow the [[Troubleshooting extensions and themes]] article for that.
    ''To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.''
    ''When you figure out what's causing your issues, please let us know. It might help other users who have the same problem.''
    Thank you.
