Z580 battery (drivers or WIndows?)

Greetings!

I bought a laptop Lenovo Z580 and got the hard drive replaced with a samsung 830 series SSD (128 GB) with a new installation of W7, the store to the 750 GB hard drive in an external enclosure and I was all this at a very nice price. The laptop was awesome.

But for the battery.

From the first day I had only 1.5 to 2 hours on a full charge of battery problems. I did check the following:
1. fact that all device drivers have been installed since Lenovo Web site (or hard drive OEM, depending on which were most recent file). I did this because the SSD had a fresh W7 install first.
2. the fact that all the windows updates were installed
3 Levono power management has been implemented fully charged battery mode Mode and not the protection of the battery (where the battery capacity is limited, less than 100%)

Problem was not resolved. I called the store and they gave me a new battery, no questions asked. DIN can't solve the problem.

Then they gave me a new laptop, with the SSD even put in. Did not work. It was two weeks in the purchase of the laptop.

I asked them to put the old HDD 750GB thinking that maybe it is the SSD. Does not solve the problem. (At this point, the laptop was as good as out of the box and I did not know THAT SSD has not caused the problem). I don't want to ask money back because I need exactly this configuration in this laptop, and at the price I got it, it is not possible (at least in the Netherlands). In addition, he's exhausted. Apart from this problem, the laptop is perfect.

During this time, I run the powercfg-energy and found a few USB devices not enter powersave mode. Output below:

I made the corrections mentioned on a few sites on the internet, and well, these things are now gone. Maybe the situation is better now, but now I get about 3 hours on a charge.

I also noticed in the advanced power settings of all the profiles that the minimum CPU on the battery condition was 5%, I changed it to 0%. Why not.

Now, the only thing that bothers me little is the continuous fan on the side of the laptop. That's all the time. Is this normal? Its not particularly noisy, but when I hold it to my ear, I can imagine the fan is very busy. I changed the "heat" to "Super silent" Managment and reduced noise and availability of the battery goes up to 4 hours. Still not here. I expect at least 6 hours for a new laptop.

My gut feeling is something to do with the drivers (yet) or some problem of management of power between 4000 integrated graphics intel and nvidia chipset. In the BIOS, I can choose Optimus (both) or intel only. But ideally, I would use the nvidia gerforce and permanently turn off the intel 4000. How can I do safely? I don't want to go to the Device Manager and disable it. If my screen uses intel right here, its all gone then. Is it not?

But before you go in this direction, am I missing something? How a Lenovo can offer only 4 hours of battery out of the box? Is the problem with my expectation?

Hi all

Detachment to close this thread - my problem seems to have been resolved.

I'm not sure what it is resolved, but I did a number of things since then, including:

-Reinstall the chipset drivers intel from the website of intel rather than the OEM folder given by Lenovo. They seem to be release late last month.

-also updated the drivers from nvidia 630M - sequence also appears to have made a difference. I don't really know how it works maybe that wouldn't take a difference too, but I seem to be the case.

-in the lenovo energy management, there is an option to disable disk when not in use. It is not given you an option after how long, but I turned on. No matter what.

-in both mode balanced and power saver in the windows power settings, I changed the switch bank hard timeout to one minute. With 8 GB of RAM and page file reduced to 512 MB only, I don't think that my system needs read/write unless I have download/copy or sleep/hibernate implementation. It does nto creates problems with the disk access performance, at least not with my ssd.

-in advanced power settings, changed the wifi to run on maximum energy savings. changed setting to maximum power save everywhere, I saw.

-usb selective suspend has been activated. disabled, restarted. permit, rebooted.

-same setting for graphics card intel

Somethins must have worked. I get a nice 8 theoretical hours from the laptop now, almost 6 +.

I guess I'm fine with it now. Problem was in the software. I do not have compalaints with WIn7, but I guess all said and done, he must do a better job to save energy.

  • Need drivers of Windows XP Home for Satellite C650D - 11K

    Hello

    where can I find all the drivers for Windows Xp for my Satellite C650D - 11K?

    I saw something on the Support page & Toshiba drivers, but the question is: if originally, it installed Windows 7 64 bit, how I can install all drivers for Win Xp (32-bit, I guess)?

    Please help me.

    Thank you.

    Your question is really strange. If your laptop is supported for Windows XP Home edition, and it is undoubtedly supported, then install WXP and more later all the necessary drivers, tools and utilities one by one.

    Before that, you create the recovery disk using the preinstalled Toshiba Recovery Disk Creator. This disk you can use to install Win7 64 bit in the future when you don t want to use Windows XP Home edition.

  • Need drivers of Windows XP Home for my Tecra 8200

    Greetings,

    I need XP drivers for my old laptop, but Toshiba has completely eliminated the drivers for their old cell phones. Where I can find these drivers? Honestly, I spend the last 30 minutes trying to find the drivers on the web.

    And I read that the WiFi does not work under XP, there were found no solution to this problem?

    Thank you for your help and btw, English is not my language stronger :)

    It's really amazing!

    It's so easy to find these things and wonder what you did 30 minutes. If you have the old model of laptop it is LOGICAL that such things can be placed under option * ARCHIVES *. Am I right about that?

    Please go to the Toshiba download page again and under * TYPE of PRODUCT * choose * ARCHIVES *.

    I really hope that this time you have just a minute to find the drivers of Windows XP Home edition.

    Bye and good luck!

  • Re: Satellite M70 - why not until now no drivers for Windows 7 available?

    Thanks in advane

    I was working on the Vista SP2 and everything is OK

    Hello

    I think that it of normally that is up to now no drivers for Windows 7 available. What do you think?

    I mean Windows 7 is not yet on the market, and it comes out in October. If Windows 7 is out, I think that the support of the pilot will also begin. On Vista and XP was the same thing, until the version of the OS a few days and weeks later new drivers was released.

    I hope for you that Satellite M70 will build for Windows 7, but I put t know. I think we will have to wait a few more weeks until Toshiba will begin support of Windows 7.

    Moreover, on the Toshiba page we you can find some beta drivers for Windows 7. It is perhaps useful to you.

    Good bye

  • NB520-10R, are there drivers for Windows XP?

    Hello

    NB520-10R comes with Windows 7 Starter. However, this BONE slows down the system much, even with the upgrade of RAM to 2 GB.
    I intend to install Windows XP, and I was wondering if there are all the drivers available for my model.
    If this isn't the case, Toshiba has any plans to release drivers for Windows XP?

    Thank you

    No, there is no victory xo drivers for this laptop model because Win XP is not supported on this unit.
    So, you will need to search for drivers with your own hands.
    You can try some unique XP drivers that are released for other laptops.
