Y580 Turbo Boost does not work except if hooked up

While watching a youtube HD video, I noticed the processor did not work properly and that's why the video was stuttering. I checked and the intel turbo boost on a monitor version 2.6 and it showed that even on dynamic graphics Lenovo plan power than the processor was not using turbo boost. When running on the battery, the monitor displays also a leaf green and written below is "Energy Saver". If I plug the charger in the laptop, the problem goes away and I can see the Turbo works very well and with it the sheet and the "Energy Saver" will too.

I've changed developed and even power settings made the processor state minimum 100% of battery, just as connected, so that it works just as well, but nothing helps. So I would like to know why the turbo boost function does not work then on the battery and only plugged him.

yurajgill10,

Intel's mode require more power that the battery can supply so it works only when the AC is plugged.

Hope that helps.

  • X 230-Turbo Boost does not work when there is only the AC

    I changed the power manager in the State of Performance Max, but when he has only AC, Turbo Boost does not work. I need to install the battary simultaneously to do the Turbo Boost. If there is only battary, Turbo Boost can function normally.

    I googled this problem and it is said that Lenovo is doing this in order to avoid the lack of power when there is AC only.  How could I do Turbo Boost only works with AC (without battary on)?

    Welcome to the community!

    There are here some information that suggests that a 90 Watt power adapter will allow what you want, but I am mobile at the moment so my research capabilities are limited. Personally, I can't confirm that it works, however, I've never run without battery.

    Kind regards.

  • Turbo boost does not work when active hyperthreading - W520

    I have ignored this issue for a long time, until I've decided to try to understand and fix it. My W520 would never go beyond 2.40 GHz, I tried all the tests in the book. Manager power AC power, BIOS enabled, the max value performance in what concerns all, power settings windows too. stress tests, single thread, multi-threaded, has no importance, it has always been to 2.40 GHz or less (800 idling). After much trial and error, I found that this turbo would work properly if hyperthreading is disabled in the BIOS. The CPU module and then between 800 MHz to 3.5 GHz as it should with active turbo. Why can I not use hyperthreading AND turbo? Is this normal?

    I also noticed that in the BIOS there is no option for turbo-boost. Just hyperthreading, multi-core and speedstep.

    W520, i7-2760qm, BIOS 1.40, all the latest recommended updates.


  • Y580 background winds does not work correctly... help!

    Hi all, I just got my new Y580 a week ago. I use HWMonitor to check the internal temperature. The highest ever record temperature is 81 c for the CPU (where the game). I think it's high enough, think that I have the laptop high about 3 inches off the table and my room is quite cold (it's winter here). So I checked to see if the low 3 vents are working properly. I think that the bottom venting air draws in to cool the Interior. So if I use a small piece of paper, he should stick to the passage because it is sucking air. The piece of paper only stick to the upper vent (the one near the ventilation hole on the side of the laptop), but not the bottom 2. Also, the upper vent feels kind of cold to the touch after extended use, which make sense, because it is sucking air. However, the lower 2 events feel the same and feel a little warm. This thread believe me the 2 vents below even does not work properly.


  • Inspiron 5520 with i7 3632QM - Turbo Boost does not

    Hello, I have an Inspiron 5520 who originally i3 2370 Mr. I upgraded the CPU to i7 3632QM and it works perfectly, but I discovered that Turbo Boost is not activate during labor. This is the diagnosis of HWinfo:

    As you can see, it shows that the Turbo Boost is not enabled. And my tests, I can definitely say that the CPU's maximum speed is rated - 2, 2 GHz without any still on the rise according to the specifications of Turbo.

    Also, I tried to install the Intel Turbo Boost monitor utility, but it gave an error saying that it cannot find CPU with Turbo Boost support. But the 3632QM says of course.

    BIOS settings have not all Turbo Boost options so it can be turned on/off from there. The version of the BIOS is available last A14.

    Why Turbo cannot be enabled on this laptop? And I saw that many other people with different computers cannot do as well. It's so unfortunate and unfair. :( How can I enable it? You are looking for your help please.

    Problem solved, I loaded a [security] default BIOS settings. Turbo Boost now works normally. Looks like it was necessary for the motherboard/BIOS card recalibrate after replacing the CPU.

  • HP SimplePass does not work except the windows log on screen

    Hey,.

    When I bought this pc, it is Windows 8. I've updated my pc to the latest version 8.1 of windows. After the first update SimplePass stopped working on all browsers except Internet Explorer. He stopped work on the login screen too. But for some reason he started working on the newspaper on the screen all of a sudden. I contacted HP through chat support. They said that SimplePass is designed to work only with Internet Explorer. Other browsers may work or not. It is very good. According to his (Agent HP) SimplePass still works.

    But after the SimplePass update stopped working completely except the login screen. I click on the icon SimplePass... no answer... I slip on the fingerprint reader... nothing happens. But the computer only works on the windows login screen. Below is my current pc info. I think that HP must update SimplePass.

    Hi Nicollo and welcome to the Lenovo user community!

    It is by design - you have the power to the system removed part. A higher power supply adapter can eliminate this problem.

    Your #navleft and #mainarea layers are positioned so that they hide
    the navigation bar. You can see this by canging the high placement of the page on
    each 300px instead of 200px.

    You have a table top why not just use a simple 2 column table
    inserted under it to house your nav and the main content?

    The problem with the use of layers is that they are positioned absolutely and
    only take into account everything that is resized on the page.

    {#navleft}
    position: absolute;
    left: 0px;
    top: 200px;
    Width: 225px;
    background-color: #FFFF99;
    layer-background-color: #FFFFFF;
    border: 1px none #000000;

  • Output TV does not work properly with my new Satellite A100-812

    Hey everybody,
    A little, I have a problem with my new laptop if not satisfactory.
    The only thing that does not work (except some progs) in Vista is out of my tv.

    After many hours spent trawling the net, I came across different solutions, but none worked.
    The A100-812 has a geforce Go7600 who has taken TV svhs.
    First, I tried to connect to my tv through my old cinch cable. It took me 2 days before I gave up and bought a new svhs cable. Cable that works now and after a hell of a lot of attachment,

    I finally have a working tv. Except that its black and white. I used the click right-> NVIDIA Control Panel and changed the signal. I live in the Netherlands, where B/PAL is the standard. But even in trying all the different types of signals I don't get any color.

    Someone else has had this problem and solved? I downloaded the nvidia latestet drivers and I'm desperate, I bought the laptop to make it work!
    Any suggestion is more than welcome.
    See you soon,.
    Retriever

    Hello

    the problem is that the nvidia drivers are still not final. I have an A100 and desktop system and two systems have problems with tv output. It s Yes, probably a clear driver problem.
    After many surveys, I found many comments in the forum of nvidia, where users are desperate and angry about this issue.
    Thus, the only choice is to change XP up to what nvidia will release some drivers work... that s my way.

    Cheers to a disappointed user nvidia

  • IPhone 6s - microphone does not work on all applications except camera and calls

    Hey, I don't know exactly know what happened with my phone. Suddenly, my microphone work on LINE, Whatsapp and almost all other applications that use mic. Except, camera and when someone call me on my number.

    But it does not work on whatsapp and LINE calls. And it also does not work when I snapchat. Only works on the default camera Apps and call through my number.

    I tried:

    -restart my phone

    -hard reset and blink? Reset with the power and the "home" button.

    -read the micro support page. Still no solution.

    TL; Dr:

    my microphone does not work on every apps on my phone except calls through number and approx. of default camera it gives you just that silence when I play it on voice notes. But it works when I record yourself using videos on the default camera app.

    Hello Bllacke,

    Thank you for using communities of Apple Support.

    I see from your post, some applications have a problem to access your Microphone. I know how it is important to ensure that your applications have access to the Microphone and can use this feature. I have a few things I want to try.

    First, tap Settings on your iPhone and then scroll to the last section that lists your apps. Select the applications that use the microphone and make sure that the Microphone is activated (green).

    Then, follow the steps in the article below to close these applications:

    Force a nearby application on your iPhone, iPad or iPod touch

    Then, test the microphone in these applications again and see if it works.

    Best regards.
