Backlight is disabled until the power management software is loaded on the Satellite M40 - 295

Greetings to all members of the forum.

I am owner of ten months a Satellite M40-295. My problem is the following:

When I start my computer the backlight is disabled until I go into Windows and the power management program is loaded.
After that the backlight of the screen lights up. I tried to change the brightness with Fn-F6/7 and screens using Fn + F5 without success.

Init information (init messages, such as the Toshiba and Windows logo) appears on the screen (I checked it under the intense light and the screen from another angle of view), so the adapter seems to work properly.

Thanks in advance

Hi Evangelos

I'm afraid that now, you have a problem. If the unit won't start the BIOS chip is probably damaged. In my opinion BIOS update was bad idea.

Right now I don't want write something on the screen because now it is not important at all. Please contact the customer Service of your country partner and let check the device. Sorry, but I'm 99.9% that the unit is now completely screwed.

If the appliance shows any sign of life is the case for the service. :(

  • Need assistance to disable Intel Link Power Management

    Hi all

    I have a Dell place 7130v - 8G of RAM 11Pro / Intel Core i5-4300Y with Windows 10. When I got the system in 2014 I lived the constant freezing with the disc synchronizing 100% on every 10 seconds, 60 seconds, then finally was interrupting, and then start again.

    I was able to use the app Board of Intel to disable Link Power Management and never had any problems again.

    Recently, I had to do a reset of the system and the clean install of Windows 10, date at which a good amount of applications and drivers have been removed (including the Intel app). As a solution, I went into the management interface of power windows, clicked on PCI express and the disabled Link State Power Management. Also, I went into the Intel Graphics tool and turned off the update automatic Panel, but I'm stil having the constant disk clock.

    What is the Intel software that handles l/min, and I can provide it manually?

    I really don't think solve a BSOD with a system refresh give me two years and I was forced to deal with 60 seconds system freezes every minute :(

    Thanks in advance for any ideas or suggestions!

    Solved my problem - ran the update of the driver from Dell and have downloaded the management tool. Link disabled pwer management and my system is back in good health.

  • Access policy for the user whose status is "disabled until the start date.

    Hello

    By default political access does not work for the user whose start date is later in OIM 11 g. I have an access policy that the provisions of all users of Xellerate OID. This policy is not work for users who start date is later, i.e. status = disabled until the start date.

    No workaround to make the strategy work is much appreciated.



    Thank you
    GYAN

    up to 10g it work very well if you put provisining date as the current date. But, you cannot apply even in oim 11g

    Try below

    Add new udf to the user profile
    reconcile the start date in the new udf and leave the start of oim null date
    In this case the access policy will be triggers and you will be able to get an account created to the OID, and then set the start workflow OID IOM

    for reminder and all just to add trigger for the new udf and update on the changes.

    Note: In your case as OID in disable State it will cause no problem after the user status "disable up to that Start Date. If the resource object in activate State and change you the status to disable up to that starting date, it does not fire disable the user trigger.

    Hello

    Sorry, but in my opinion there nothing to do.
    You cannot move all the keys on the keyboard.
    It s is not possible.

    What you can do is to change the keyboard language in the settings of the OS, but I t I think the function of the ALT GR key will change.
    Another possibility is to change the keyboard to another provision, but these make no sense because you will not be able to use the special Polish panels.

  • Power Manager, software of finger printing does not start

    Hi all

    I was faced with a problem recently on my x 220 install win7 32 bit. Power Manager (3.66), software of fingerprints as well as the graphic Properties utility intel is unbootable. FN + F3 displays nothing more.

    I am only able to see the splashscreen and then nothing happens and the process stops.

    I tried to uninstall and reinstall either manually or through lenovo software update without success

    I wasn't able to find a log file in C:\Program Files\ThinkPad\Utilities or the windows event viewer.

    I thought it might be related to a recent update .NET, but I have tried several versions with no success (currently using 4.0).

    Do you have any idea what I can do for troublesshot/fix this?

    Kind regards

    OK, so I could fix the problem by disabling the Windows Presentation Foundation 3.0.0.0 Cache of police service in services.msc.

    Since then, everything works, Power Manager, fingerprints, tool box...

    I guess an update of recent security reactive .NET service and my cache is corrupted somehow.

  • Corruption of the BIOS to the Satellite M40

    Hi all.

    I have an old laptop Toshiba Satellite M40 with damaged BIOS which of course does not start. TI powers drop down 3 sec after power, which means that it does not pass the test STATION. I understand various forum that it is not the competence of technicians ASP and I'm not ready to hear things like 'replace maother Board' of these guys.

    I heard talk about techniques that can reflash the BIOS in the CMOS memory using a floppy drive loaded with a version of BIOS.

    The computer is in pretty good condition, including a new 80 Gb HD and was working fine until I tried to update the BIOS. I think it should be fix and spend a few hours on it.

    Any ideas on the issue were greatly appreciated.

    Hello

    I'm afraid that you are ready to hear just a positive thing or what. Are you here to have the real discussion or you want to hear a fairy tale. You wrote in your ad that the BIOS is damaged. I guess that you know very well what should be done with pieces of damaged equipment.

    How you want to reflash the BIOS if your laptop is running in only 3 seconds. Please be serious.

    Hello

    I m a M40 owner but I did not install Vista on this unit. I use the XP.

    Is the laptop has Vista capable sticker? I don t think so :(

  • Peripheral USB do not work correctly on the Satellite M40 313

    I have a Satellite M40 313 I bought there are about 1 1/2 years and have had some problems with.

    However, I recently bought a Canon S3 IS and a Buffalo portable HD here in Japan, where I currently work.
    These two devices do not work with my computer.

    Attach the HD produced the message that this device will work better with a USB 2.0 high speed Port, before XP decides that the HD is actually a keyboard HID device! The camera mount, for which I had installed the software provided, will produce a message that suggests that I have install usbscan.sys file and forces me to use a driver of generic digital camera that does not work with the Canon camera.
    I fetch the requested file, but it made no difference...

    It seems that it is a problem of USB, and I also noticed that some of my friends devices USB do not work well with my computer.

    In this case, what is the best way to update my software so its compatible USB? Have I been dismantled down to the USB 1.1 version by WIndows at any given time? The pilot on the hub root 5.1.2600.2180 and is dated 07/01/2001.

    Any suggestion is appreciated.

    Hello

    Perhaps a biosupdate could help you? I mean it s do not know if is it a hardware problem or software, so that you can first try to check if it s a software linked history by:
    1.), updated the Bios
    2.) recover the system with the recovery cd (backup your data first!  ;))
    3.) install the latest drivers (do not install MS updates or patches, sometimes they cause errors)

    If you have no success after completing these steps, and then give a few comments.

  • What is max capacity of the HDD on the Satellite M40-101

    What is the maximum capacity of the disc HARD can be installed in the laptop M40-101?

    To my knowledge, some of the Mobile Satellite M40 were shipped with the hard disks of 80 GB (IDE).
    I didn't find any official Toshiba information about supported tough max, but I guess you should be able to use the 100 GB drive HARD; Maybe a 120 GB HARD drive too.

    Seems that you have to test.

  • I can't retrieve the Satellite M40 (M45 in the United States)

    I put Ubuntu Linux on the laptop using the bootloader Grub 1.5.

    Then... I did something stupid. I used Partition Magic to increase the space for Windows. I don't mind losing any data, or nuking the drive and put back in operation, but it does not seem possible?

    When I put a boot disk (if recovery, Windows or Ubuntu) I get "Grub Error 17 1.5". I changed the boot options to boot from the CD first, but for some reason that always happens, and bios is kind of limit on what I can do. Now on the software still works, but I don't know of anyway have a boot disk.

    Help! I hate the idea that I have fried my phone on a software problem? :(

    Hello

    I m not an expert in Linux but for as far as I know this error message appears if the boot partition is available, BUT the file system is no more recognized by GRUB.

    If you try to boot from windows to check the grub.conf file contains entries
    root (hdX, Y) (or rootnoverify (hdX, Y)) and (hdX, Y) chainloader + 1

  • Problem of management of power with the Satellite S2430-402

    Every time is start my laptop, I get a message saying "%1 is not a valid Win 32 application" under the heading "E-power", thus the Toshiba power management does not load. I tried to uninstall and reinstall the software from the cd, but it does not work, and I still get the message.

    The problems began after I installed a program called Ghost Surf 2005 and ran for the first time. Since then I uninstalled but still has problems. I am running Windows XP operating system.

    Can anyone help?

    Hi Dan,.

    It seems that the software corrupted a file which is responsible for the powermanagement! There is what we call common files and it can be replace a file, the installation of Ghost surf!

    You can try to solve it with the Windows XP system restore when you set a restore point! Back to a restore point that was resolved before installing the software!

  • Sat L20-102: need software for power management

    Hi, is there, a L20-102 Sat power management software provided by Toshiba? I can't find Power Saver for my model to download driver...
    With the standard windows power management, I have to manually reduce brightness when you go to the battery and the occasional fan runs at max speed for a second and then slows down the acceptable level, runs for a few seconds and then turns off...
    These "rpm max" chips are quite boring :(

    I see Power Saver has plenty of features, and probably he ' d suite my needs, but it is unavailable :/

    Is there a good alternative?

    Hello

    I know it sounds strange but your unit is pre-installed without intelligence tool. This is the reason why you can not find on the Toshiba download page. Please don t try to install this tool, designed for another unit, because you may have some trouble and many error messages. As far as I know all the tools must be adapted for each laptop model.

    On some devices, this tool only works if other components are installed. I guess L20's budget unit and for this reason, it isn't stuff as on other units.

    Good bye
