    I recommend you to roll back the OS to the beginning.
    You can use the system restore which is part of the Windows operating system.
    I guess you have removed or replace some settings or files and restoring the system must bring these parameters at the beginning.

    Hello ladies and gentlemen, I would appreciate any help that you can offer to the prediciment I'm in that:

    I tried a reinstall on my Toshiba satellite pro A100 model girlfriend. PSAAPE-00H00KEN.

    The problem is I ve come across are the controller Ethernet is said it is unknown, and is the same for mass storage, PCI, Bus SM and the video and video controllers VGA device.
    So when my LAN cable connecting, it registers only as a 1394 connection and is of little use to me.

    Also I m leads to believe that the laptop could be an Asian model?

  • Bluetooth is not recognized on Satellite Pro A100

    I have a Satellite Pro A100 828 running Win XP Pro.

    He is supposed to have integrated bluetooth but when I install the bluetooth stack, a message appears saying peripheral usb has malfunctioned and is not recognized by windows.

    In Device Manager, it is listed as an unknown device.
    I tried different versions of the bluetooth stack, but the same message still appears.

    Is there a software fix for this or does this mean that my hardware is defective? Would be grateful for any advice.

    Thank you.

    Hello

    where downloaded battery Bluetooth? And another question: do you have bluetooth never work properly? It would be interesting.
    Try another might be to download a Linux Live-CD and to check if the problem is perhaps more a hardware related issue.

    So, if you need an alternative download source then try this address:

  • Satellite Pro A100 - how to get the Wlan connection works

    Help!

    I'm a total beginner, and my problem is I can get a connection without wire only when I'm really close to my BT hub.
    My son has a laptop and gets a good connection anywhere in the House and even outside.

    He thinks I have a dodgy wireless adapter, this could be the problem?
    Can I fix it myself?

    Maybe download a new driver?
    Any suggestions would be much apreciated.

    TOSHIBA SATELLITE PRO A100

    Hello

    Your ad is not really useful.
    I mean that there is no detail about your problem
    You should first check if the laptop supports the wireless network card.
    This can be done in the Device Manager.

    Usually the WLan card must appear in Manager devices-> network adapters.
    If it s are not it is that the WLan card is not built in or the driver WLan is not installed. If the WLan driver is not installed then you should see yellow exclamation (or unknown device).

    But if the wireless network adapter is listed correctly then you should check if the WLan notebooks have been enabled. In order to activate the WLan you have to press FN + F8 and you put the switch on IT until the small LED flash.

    Finally, to configure the WiFi connection (right name WLan, encryption settings, etc...)

  • Satellite Pro A100 support Micro SD card?

    Hello.

    I have a Satellite Pro A100 (model PSAAPE - OOTOOKEN).
    It has a card on the front slot and the manual says "this slot allows you to easily transfer data from devices such as PDA and digital camera that uses flash memory (SD/MS/MS Pro/MMC/memory cards xD).

    I want to buy a Micro SD (microSDHC) memory card for use with a tablet PC, I intend to buy.

    My question is, if I insert the Micro SD (microSDHC) card in a SD adapter and insert it into the slot of laptops, laptop will accept for read/write operations?

    I was wondering if I can get away with having one type of card for laptops and tablet, rather than a microSDHC for the tab and a SD card for the laptop.

    Thank you.

    Hello

    The user manual provides information on the supported cards.

    Supported are:
    8 MB to 2 GB SD card
    MMC (multimedia) card 8 MB to 1 GB
    8 MB to 256 MB card MS (memory stick)
    MS (MemoryStick) Pro 256 MB to 2 GB
    16 MB to 1 GB xD memory card

    > My question is, if I insert the Micro SD (microSDHC) card in a SD adapter and insert it into the slot of laptops, laptop will accept for read/write operations?

    Since supports up to 2 GB card SD card reader, you should be able to use the microSDHC in relation to a SD card adapter.

  • Satellite Pro A100: How to get updates for driver for ATI Radeon Mobility X 1400

    Hello

    I am aware that the driver for my on-board graphics card is outdated.
    When I download a updated from ATI driver and try to install, it tells me that I can't install the update the system there and contact Toshiba for the updates.

    Please can someone tell how can I get a driver updates for this card on my Satellite Pro A100 series?

    Concerning

    Macca.

    Hello

    You can not install drivers ATI ATI site because these drivers are not designed and certified for Toshiba laptops.
    These drivers can affect the functionality of notebooks and in worst cases could overheat your GPU

    * So if you want to use these drivers, you can do it but only at your own risk! *

    You can install this driver in Device Manager;
    You must use the Advanced installation procedure and you will have to indicate where the graphic driver files were stored on the HARD drive

  • Solution for DVD playback choppy on Satellite Pro A100

    Hello!

    I had this problem twice on my Toshiba laptop (Satellite Pro A100 bought in April 2006): the DVD used to play very well, but now (perhaps after an update of the driver or installation of software, I not sure what causes this) DVD playback is choppy, distorted sound. This occurs throughout all media players on Windows XP (for example, PowerDVD which came with the laptop) or Windows media player.

    I searched the internet far from a solution and finally found how to solve this problem:

    Go to Device Manager, select the "IDE ATA/ATAPI controllers" section, and then select the "second IDE channel", right click and 'uninstall '. (There are two second IDE channels, if you know which then just uninstall both.) Restart Windows XP, Windows XP will automatically reinstall the drivers without the need to download anything. Subsequently the DVD Player reads normally.

    The symptoms of the problem, apart from DVD playback choppy, are the "transfer mode" gets stuck on PIO for a reason, and bring back to DMA with no opportunity to spend. I have no idea what software or driver causes this, or why, but if this is your problem too, if you think that this solves.

    Cool, thanks for the inquiry and the nice information.
    Could be useful to others here in the forum.
    Nice to have these community users :)

  • Where did my WLan connection part for Satellite Pro A100

    Hi all

    I recently reinstalled xp on my Satellite Pro A100 and I can not get the wireless connection works.
    He worked prior to re - install. I downloaded a bunch of driver but cannot make it work.

    any suggestions?

    THX
    Tim

    Hello

    First you should check if the WiFi network card status in Device Manager.
    You can see a Wlan card?

    If you n t see the Wlan card listed in the network adapters, it would mean the failure of the driver installation WiFi card or you have used is not compatible Wlan driver!

    I m not to mention of course that you have the card Wlan but there are only two options; It s Atheros or Intel.

    I recommend you to visit the European driver Toshiba page and download the latest Wlan driver for this device.

  • Need drivers for Windows XP edition family 64-bit for Satellite Pro A100

    Hello

    Where can I find drivers for Windows XP 64 - bit drivers for my laptop Toshiba Satellite Pro A100 (PSAACE) series? I was looking on
    [this site | http://eu.computers.toshiba-europe.com/innovation/download_drivers_bios.jsp?service=EU], but there is for the 32-bit version of Windows XP.

    Thank you

    Yes, you are directly on the European driver of Toshiba page you will find only the 32-bit drivers XP and Vista.
    It seems that the Vista 64 bit drivers are not being released especially for this series of laptop.

    But don t give up buddy;
    Several series of laptops are equipped with the same features. SO try a few only Vista 64 bit drivers from other series that supports the same devices.

    In addition, you can search on some external 3 Web sites from third parties for the Vista 64 bit drivers.
    Many manufacturers of chips provides 64-bit Vista drivers own address for specific devices.
