  • Portege M200 display issues

    Hello. I just got my new M200 tablet pc, but the display is sluggy compared to my screen Tecra S1. Looks like there is something on top of the display Assembly that makes sluggy image and the colors too. This can be seen especially on white background. Is there a plastic to remove, because I looked and I think he does not like or is it normal for the tablet PC?

    Hello

    The Portege M200 LCD screen is covered with a protective mask. This protective film is integrated into the LCD mask to prevent scratches on the LCD Panel - caused from dirt or handling - caused by the use of the pen.
    You can't compare these two screens (Portege Tecra) for Portege is tablet pc with the protective mask and Tecra has a very different display with other properties.

  • Vista on Portege M200 - some problems with nVidia display driver

    Hello

    I recently decided to update and perform a clean installation of Windows Vista on my Portege M200, now that Toshiba have released official drivers for this machine.

    Everything works fine, EXCEPT the nVidia display driver. I have the following questions with the driver Toshiba provides for this machine (97.52 version):

    (1) when the screen turns off to save power, the backlight does NOT turn off. Screen turns off but the backlight will stay lit.
    (2) for the recovery of the standby mode, the backlight is OFF. You must use the shortcuts Fn-F6/F7 to change the backlight level manually, that will bring him back.
    (3) external monitor does not work (with command Fn + F5 or nVidia control panel). External display is always blank.
    (3) video playback in WMP is very chopped (a secondary concern for me).

    Is there a chance that Toshiba could finally get a updated driver that would set out the? That would really make this machine fully functional in Vista.

    Thanks in advance for any help or information.

    Null value

    Hello

    > Are there opportunities that Toshiba could finally get out an updated driver?
    I noticed that from time to time new updates of pilot (any series of notebook) are released on the European driver Toshiba page and, therefore, I m optimistic that new updates are available

    But note; usually, various problems can be resolved by installing some patches MS Vista and missing patches.
    Then visit this [MS update website | http://www.update.microsoft.com/microsoftupdate/v6/default.aspx?ln=en-us] and check if all the patches are installed.

  • 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.

    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 does not start

    I have a Toshiba Portege M200 with Microsoft Windows XP Tablet Edition. When I turn on the computer, I get the following message is displayed:

    PXE - E61: Media test failure, check cable of
    PXE - MOF: Exit Intel Boot Agent
    Insert system disk in drive.
    Press a key when you are ready.

    When I insert the recovery and Applications/drivers DVD Portege M200 Series, the same message will reappear.

    What is my next step?

    Thank you.

    This message appears only if the safe portable couldn t of the other sources and tries to boot from LAN.

    The question is; Why the Portege M200 doesn't boot from the HARD drive?
    In my opinion, there are two possibilities; There is no OS on the HARD drive or the HARD drive died.

    I think that this should be checked first

  • Stylus stops working - Portege M200

    I have a Portege M200. The pen stops working after a few minutes use. Windows XP displays system error event log against the driver. When I reboot it starts working again.

    The touchpad still work OK.

    Drivers have been updated.
    Any ideas?

    Hello

    Special software of Toshiba is responsible for the use of the stylus on the M200.
    I have your case it seems to be a software malfunction. In my opinion you should try to remove this software from the operating system and after restarting try installing it again.
    I think that this procedure should resolve this problem.

  • Portege M200 will not install product recovery.

    Hello.

    I have a laptop Toshiba Portege M200 (model No.: PPM20A-00LG4). Three years ago, that I ran the recovery of products and records program to get a new install of XP Pro. Then I loaded all service packs of the internet. Very well, everything worked fine and the perfermed the laptop.

    Recently, the laptop was quite slow, so I decided to do it again.

    I booted the laptop on the program of recovery on the external CD-ROM drive. He reformatted the HARD drive, etc. I then installed the product recovery CD four amount requested by the installation on screen menu and the laptop seemed to accept them. Then, when invited to "Remove the disk from the drive and press a key" the laptop restarts but does is display a white blinking cursor against a black screen, for hours. Nothing happens.

    After pressing a button to restart, the Toshiba flash appears with different sources of boot, the HARD drive is first, then just the blinking cursor. I tried to re - start the laptop but get the same routine and then the blinking cursor.

    I'd appreciate really no clue to the diagnosis.

    Thanks in advance for any help.

    Hey,.

    The blinking cursor means that the operating system can t be started. To me it sounds like that, something was wrong during the installation of Windows.

    I recommend reinstalling Windows if more boot of the Toshiba Recovery disk and follow the instructions on the screen. In other words, do the same steps that you have already done and check what happens.

    Such things as installation doesn t work properly can occur without any particular reason. So, don t you worry and just test it again. ;)

  • How to activate the screen touch tablet Portege M200?

    Do I need a special driver for the touch-table display on the Portege M200?

    I installed about 35 drivers from this site,

    What could be the reason - do I have to enable it in windows?

    Why you n t use the Toshiba Recovery CD?
    The CD contains an image with OS, drivers, tools, utilities and the whole system was already configured.

    However, I assume that you have a Windows XP.
    On the European driver Toshiba page, you can find all the necessary drivers.

    I checked the drivers for the edition of Windows XP and found

  • 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.

  • Portege M200 - the hard drive failed

    My 60 GB Toshiba hard drive failed in my Portege M200.

    I tried mounting a hard drive, I had in my old laptop, a 30 GB Hitachi hard drive but the laptop doesn't seem to recognize it. Does need a Toshiba hard drive or is the laptop died, when I put the hard drive in I get message invalid startup disk.

    The old hard drive goes to a blue screen then restart the laptop.

    No there not Toshiba HDD only. I found the list of some compatible hard drives for this old Portege.
    You can use follow hard drives:
    -TOSHIBA HDD2193B
    -TOSHIBA HDD2171B
    -TOSHIBA HDD2184B
    -TOSHIBA HDD2194B
    -HITACHI G8BC00014410
    -HITACHI G8BC00014610
    -HITACHI G8BC00015610
    -HITACHI G8BC00014810

    Anyway, when you try to use new BIOS to check updated HARD drive and if default settings the new HARD drive will be recognized correctly in the BIOS settings.

    Old HARD drive is recognized correctly in the BIOS settings?
    Have you tried to install the OS by using old HDD?

    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.

  • Re: Portege M200: need to start Win XP boot disk

    Hi all

    I'm looking for a boot floppy to boot XP tablet edition disc 2005 on my Portege M200.
    If someone could point me in the right direction that would be great.

    Hello

    You must initialize disc?
    I wonder why you need this disc?

    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).

    _Following and controllers (USB, PCMCIA) can be used: _

    The setting of 'PC Card Controller Mode' in the BIOS should be 'Automatic Selection '.
    This means that you have nothing to change in the BIOS, because it is the default value.
