Lack of power on Portege M200 USB

I found a few posts on this topic but nothing that gives a definitive explanation of how to solve the problem of the lack of adequate power to the USB ports on my M200.

I have a burner DVD of LaCie which works perfectly satisfctorily on other computers when it is powered by USB, but does not on my M200.
I also tried to use a simple box of HARD disk with a hot spare in there and it does not work either.

I tried some of the suggestions from other threads like by unchecking the box "Allow the computer to turn off this device to save power" in the tab properties for the USB hub root in Device Manager. and I've updated the drivers available.

What else to do?

Hello

What of the external USB hub with own power?
My brother uses a USB external 300 GB HARD drive, and this feature works only if the external USB hub is connected between the HARD drive and laptop computer from other manufacturers.

I think it could be a similar problem with your external burner.

  • Not enough power USB on Portege M200?

    Whenever I try on my Portege m200 portable USB devices, they do not work as long as they operate in a mode powered by bus, for example without external power. I wonder if the Portege does not offer enough USB power for some devices.

    Here is what I tried:
    (1) Freecom FS 50 - a slimline dvd burner comes with 2 usb cables. According to Freecom they will be powered by usb simply by adding the power of 2 usb ports. Result: The drive is not yet seen in my m200. Using of external power supply, the drive works by usb as expected.
    (2) pinnacle PCTV 200e - external dvb - t receiver. Is recognized, but produces errors in any receiver software I've tried. However working on the FUSi Lifebook S series.

    Can anyone confirm the waekness of USB ports? Suggestions or tweaks plus a train external powered usb hub?

    Hello

    The USB ports provide 500mA. It is a standard USB. If the external USB devices need more power than USB ports allow in most cases the external power supply is required.
    You can also try plugging the USB hub with an external power supply, then connect the external USB devices to the USB hub.

    In addition, you can try to change the settings in the properties of the USB root hub.
    Go to the device manager select USB hub root, select properties and go to the power management tab.
    Here, you can disable the option: "allow the computer to turn off this device?

  • Portege M200 won't start CD-Rom USB

    I tried used, pressing C, changing the Bios and F12 boot boot from CD-Rom. None doesn't seem to work, if anyone has any other suggestions I would be grateful.

    Hello

    Unfortunately I can't help you much about it because I do not have this Portege but I found interesting news on the Portege M200 and support for recovery disks:

    The Portege M200 supports the recovery through the BIOS (by pressing 'C') with the USB 2.0 card and PCMCIA (16-bit and Cardbus).
    Readers and following (USB, PCMCIA) controllers have been tested successfully:

    one) Toshiba, PA3352E-SCD2, CD-RW/DVD-Rom USB 2.0 drive
    (b) Toshiba PA3402E-1DV2, Rev.501, USB 2.0 DVD Super Multi drive, SN: 5362870112
    (c) Toshiba, PX1055E-1NST, (Freecom drive), SN: 3431490096
    with a PC Card (16 bit) card, cable II, PCMCIA, Rev.043.242, SN: 18496 043 3999 0343 01093
    (d) Toshiba, PX1055E-1NST, (Freecom drive), SN: 3431490096
    with a CardBus cable II, MAP of BUS, Rev.136, SN: 16693 136 3999 0149 06122

    The drive used in conjunction with the Contoller PCMCIA or USB is not so important due to the fact that the driver in the BIOS should allow the controller first.
    There is a generic CD-ROM drive implemented in the BIOS for the connected player.

    Tested with:
    Toshiba, PX1054E-1NST, (Freecom drive), SN: 151192845
    Card CardBus, cable II, CARD BUS, Rev.136, SN: 16693 136 3999 0149 06122

    The "PC Card controller Mode" settings in the BIOS has been 'Automatic Selection '.
    This means that you have nothing to change in the BIOS, because it is the default value.

    It could happen, to connect the power supply in certain circumstances, for example:
    Battery is charged too less.
    The PCMCIA supplies unless energy location.

    Recommendation:
    If a player is used with a built in battery, please always connect an appropriate adapter.

    For the recovery of USB 2.0, 2 following drives have been tested successfully:
    one) Toshiba, PA3352E-SCD2, CD-RW/DVD-Rom USB 2.0 drive
    (b) Toshiba PA3402E-1DV2, Rev.501, USB 2.0 DVD Super Multi drive, SN: 5362870112

  • Portege M200 - weird display with docking station problem

    Hello

    I use a Portege M200 with MS Windows Vista and the Toshiba docking station. Whenever I connected the system closed down it will start with low light and different screen resolution. The brightness can then be adjusted in Vista.

    To solve the problem, I have to disconnect it, then put it in PC Mode and finally stop Vista. With the next offline boot, it works correctly and can be re-docked. Maybe it's just a lack of understanding of the system? It seems that with a rooted boot, nVidia somehow takes place or is there different profiles?

    Thank you!

    Alexander

    Hello

    At first, I must say that Portege M200 is old enough laptop model and I really wonder that Toshiba supports this model of laptop for Windows Vista. You are really lucky in this regard.

    In any case very important is info which edition of WXP Tablet Toshiba offered tools for/disconnect. If I remember well, it was utilitarian Toshiba Mobile Extension. Using this tool you has been able to use different settings for Bay service as well as for output screen to choose the correct resolution.

    Under Vista it is controlled by Vista and, AFAIK, Toshiba does not have any special utility for this. You must also understand that procedure/disconnect (power switching power supply) is controlled by Vista and I can imagine that under Vista it does not work perfectly.

    My opinion is that there is not much to do, but I hope I'm wrong on this issue. Let's see what else users of forum about this.

  • From a Portege M200 battery mode screen

    Hello, first sorry for my English, I am not totally bilingual.
    So I got a Portege M200, with the model number: PPM21E-02QFZ-FR, serial number: 55893043G

    This work of the computer laptop but fine * when I unplug the AC adapter black screen come *, when I reconnect light screen again (he continues to work, but without screen because it serves not next).

    I have try the Fn + F5 combination, not worked, try to change performance settings in windows, without change.

    When I go into the BIOS I can make it happen this problem even if the AC is plugged by changing the value of the field 'battery saving mode' to 'full power' to the other (when I change the screen turns off the coast).

    do you know how to fix this?
    Thanks in advance

    > This laptop work well, but when I unplug the power of the screen in black, when I reconnect light screen again (he continues to work, but without screen because it does not fuel nearby).

    Sorry I mate m afraid I did not understand it correctly.
    If you unplug the AC adapter, the screen turns off.
    But what happens if the power adapter is connected again? You say that screen lights up again, but then said you that you can work but no screen.

    So I'm confused now

    In my opinion, you should check the Windows power options.
    Usually, if the AC adapter should be disconnected, the laptop will switch to another power plant (battery mode).
    In my opinion, you should check the settings of the power station, which is used if the AC adapter is disconnected.

    The key is a utility called 'pom200t1 '.

    You will need the following.

    A floppy disk or if you do not have an external floppy drive, or if you are common sense to be able to boot a file from a CD player.
    You must also WinImage, as all files that you download come as .ima files
    Download pom200t1 - V1.5.zip and pom200t1.zip (if if doesn't work either).

    You can find them here:

    http://www.stormpaintball.com/Toshiba/pm765.bin (this one is a ditch last attempt).
    Then follow the instructions on the site I posted before:

    Symptom: CPU remains constantly 598 MHz.

    * Process: *.

    (1) boot in the BIOS. (Press "Esc" during the boot process, before the loading of the operating system, but after having entered your password, if you use the startup password protection).

    2) look under 'Other' category.

    (3) if the motherboard does not have enough information about the CPU, the category 'Dynamic CPU frequency Mode' appear on (you won't see it).

    If the laptop is in this state that he won't ever faster than 598 Mhz until you perform the following procedure.
    Note: Although this utility said it's for a Toshiba Portege M200, the particular difficulty you need may work on other Toshiba laptops.
    He has worked on 3 different Toshiba Satellite Pro M15 S405s, but * USE at YOUR OWN RISK *.

    (1) start Windows and create the startup disk in the pom200t1.exe file.

    (2) boot from the diskette you just made.

    (3) in the menu, select the initial repair option 2 "set config".

    (4) in the following menu, select option 1 'Initial cofiguration"(misspelled)

    (5) after a few seconds, you should see "Writing a file is over!" and the laptop restarts automatically without asking for confirmation.

    (6) when restarting the laptop go back into the BIOS and look under 'Other' category. You should now see the "dynamic CPU frequency Mode". Make sure it is set to "Dynamically switchable" for the CPU limitation.

    7) restart Windows and make sure that the CPU can throttle in normal conditions. The Intel SpeedStep technology icon should now be in the systray. Go to the Toshiba power management / Power Saver Properties and update all of your methods to save power to use technology SpeedStep that you prefer (fixed or automatic) and mount all caps speed processor, or you can go above 798 MHz because cursors will always be to their previous settings (4 or less), while they can now go up to 7. Let me know how you go.
    I have fixed the CPU now just need to find out why my fan only works when I activate it manually!

  • Portege M200 BIOS update running Windows 7?

    Hello

    I recently took a Portege M200 and installed (via PXE - network installation) Windows 7 above. I want to upgrade the BIOS as is always in the original BIOS (1.1). I downloaded and extracted the pkg and tried to install through Windows but it says that my OS is not supported. I don't have an external CD drive or floppy drive - how do I update the BIOS? I tried to put it on a USB key, but it doesn't seem to be an option to boot from USB.

    Thank you!

    > I downloaded and extracted the pkg and tried to install through Windows but it says that my OS is not supported. I don't have an external CD drive or floppy drive - how do I update the BIOS?

    Seems that BIOS cannot be updated because Win 7 is not officially supported on this good old classic.
    However, AFAIK the VAP (value added package) is required to run an update of the BIOS. So, try to install the VAP. Choose this tool which is available for other models of laptops.

    I think you don t know a fact. The diskette of starting in not necessary but you need a compatible CD/DVD player if you want to start from the CD or DVD.

    The Portege M200 supports the recovery through the BIOS (by pressing 'C') with the USB 2.0 card and PCMCIA (16-bit and Cardbus).

  • Portege M200 - bought on Ebay and frustration comes

    Hello

    I m new here and I want to ask for a warm welcome. I purchased a M200 on Ebay and he received two days before. The M200 hasn t had a DVD player and I have no recovery CD or software for my Toshiba. I have a Toshiba external slimline PCMIA CD-ROM, but more of him later.

    I found a lot of information based on this topic, but really nothing has worked for me, that article why I ask my questions here. So far, I'll tell you what I tried...

    I bought VISTA Home Premium and want to install on my M200.

    On my M200 FreeDOS short.

    I tried:

    1. use my USB drive as a floppy using a HP tool that simulates a USB drive as a disc of floppy (FDD). I ve a copy all the contents of the Vista DVD for my USB. Then I ran the BIOS on the M200, select FDD as first boot option, but nothing happens, it still start FreeDOS.

    What I'm doing wrong, Boot USB (diskette) works on the M200?

    2. as there is an external Toshiba CD Player included in my M200, I thought the first installation of a Windows XP disk. In the first period the player seems to not work, but after some time, it worked and I put my Windows XP on it. He loaded the disc, and the typical blue screen for the start-up of the plant came. But after a few seconds he stopped and said "could not read the data xxxxxx.xx, error 7. I tried two more times and same error appeared, only that it was another file that could not be read, and another error number.

    I read and I don't know if it's true:

    I have red somewhere that I can only install Windows XP which was used on the recovery CD from Toshiba (that the CD was not included in my M200). So I can't use for OS install the recovery CD and any other normal XP CD?

    Or is there an error with my external CD drive? Currently, it doesn't work again...

    3.

    I have red the following link to install Vista on M200 by a PXE server:

    http://flimflan.com/blog/InstallingVistaOnYourToshibaM200.aspx

    and this one

    http://home.allegiance.TV/~joem298/

    The first link says I can go point 13 of the second link:

    Umbrella and that's what bothers me. They tell me. Turn on your Toshiba M200 and press F2 to select the network. I press F2, but nothing happens, I see the Toshiba logo but nothing happens... If I press on enter, then come back to FreeDOS...

    Also on the second link, I tried to start from the point 1. But in point 5, the word:

    Unzip the contents of "BFD package full v1.0.7.zip" in a temporary directory. Open a command prompt and navigate to the temporary folder. Run the command "bfd msnet" in order to create the startup disk.

    I don't have a floppy drive. They tell me to run bfd.msnet from the command. Cmd.exe command is? If Yes, what should I type in to get bfd.msnet run?
    ---------------

    I knew that installation would be very difficult and I kindly ask for personal assistance. If you can speak German, it would be nice to answer in German.

    Up to now

I removed the drive, checked that the winload.exe is present on the HARD disk, it is, and it is in its original version / size / format the date created.

    can someone give me clues, or maybe I'm on the wrong track.

    Hello Daniel

    AFAIK it of not necessary to install a common Modules if you want to update the BIOS. You can normally find the common Modules to add and remove programs. If you need a whole instruction how to do a BIOS update, you can find it on the Toshiba site.
