Crazy touchscreen on my Satellite U840T-102

Hello

I bought a Toshiba Satellite U840T-102 in March and for a few weeks sometimes the touch screen go crazy, as if I touch randomly, but I'm not in touch with her. If I restart the laptop, the problem seems to disappear for a little while, but then no reason he again. I don't know what kind of problem is (is a problem of operating system or laptop?) and what to do!

Please help me!

There is a simple way to check if this problem in the system.
You could retrieve the laptop to factory state using the HDD recovery procedure or the recovery media.
Then, you will get the same State as on the first day of purchase and from my point of few you need to test the functionality of the touch screen once the laptop has been set for this State.

  • Still waiting for the new Satellite U840T-102

    We sent the laptop in the subject to support Toshiba in Italy on 5 May. File n. 73040100. After a few emails June 20, we received the proposal to change the product and sending us a new.

    We have NOTHING yet. Our clientele is more waiting for two months for a WARRANTY SERVICE.

    Is this right? It is the policy of TOSHIBA?
    CAN WE HAVE A CERTAIN DATE?

    I understand you very well buddy.
    It s always pity if the laptop is not working properly and if something needs to be replaced.

    I think there is a reason for the delay and I recommend you contact the ASP in Italy once more in order to clarify this matter.

  • Satellite U840T-103 - touch screen stopped working

    Hi, I have a Satellite, U840t-103.

    The touch screen has stopped working earlier.
    I don't know why.

    I think I have been juggling the project button, but I still can't get it to work again.

    Help, please.

    Hello

    Touch screen don't need any special driver of Toshiba.
    The driver is already part of Windows 8 / 8.1
    That is why I don't think there is a software problem, but of course, I would recommend you to retrieve the computer laptop back to factory settings using the Toshiba recovery disc just to check if this procedure would allow the touchscreen feature once more.

    This is a first common procedure in case something bad would happen to the laptop or the system.

    But if the system recovery doesn't help, the laptop must be verified by the service provider allowed for possible hardware malfunction. But let's hope, the recovery procedure would solve your problem.

  • Upgrade satellite 1900-102, hard drive

    Hello... My laptop is a toshiba satellite 1900-102 with a 20 GB hard drive. I would like to ask if I can upgrade the hard drive with another model and not the classic toshiba MK * 18GAP. Is it OK to use a hard drive from another provider? I want to use a Hitachi drive, which is less expensive, but it will be compatible?
    Thanks in advance!

    Don't know anything about Hitachi, but what speaks against an exchange of hard drive?
    The most important is the measures of the hard drive.
    As for the ability I can just tell you that we have a Satellite of 1900 with 30 concerts running

  • Satellite 1900-102: power management utility installs in XP SP2

    Hello

    I was wondering if anyone has encountered thi problem before:

  • Is satellite U840t-103 - possible to downgrade to Win7?

    Hello

    does anyone know if it is possible to downgrade to win 8.1 for win 7 on my Satellite U840t-103?
    Need to use internet explorer 8...
    I'm a little worried that he will be absent drivers.

    Tobias cordially

    Hello

    I checked the download page of Toshiba on http://www.toshiba.eu/innovation/download_drivers_bios.jsp and there is no support for Win7.

    In General, Win7 installation should be possible, but if you find no drivers, tols and utilities it has no sense for me to do.

    By the way: don't forget to create a recovery (DVD or USB) media.

  • Satellite U840T - mouse disappears on the right of the screen and down

    I have a problem with my Satellite U840T screen

    The mouse disappears on the right of the screen and the background in the black bars at the top and then the left side of the mouse cannot go to bars.

    In the display settings, everything is good, I think.

    Thank you for your help

    Hello

    I confused m.
    Your question isn't described very well.

    What do you mean exactly by: mouse disappears on the right of the screen and the background in the black bars at the top
    Do you mean the touchpad or the cursor?
    The laptop's touchpad supports the (multi-touch) gesture control feature, and this feature could be configured in the settings of the touchpad:
    + Control Panel-> mouse-> device-> settings settings tab.

    You will also find the option called shots of edge which opens the charms, app Switcher bar and toolbar Application simply by moving your finger between the edge of the touchpad to the centre.

    In this case the cursor is not visible.

  • Update hard disk for Satellite 1900 102

    Hi all

    I used to work with a Toshiba Satellite 1900 102 since July 2002 and March my hard drive has stopped working (maybe it was time).
    Where can I buy records 2.5 "that this series of satellites can be supported?

    What is the maximum capacity (in GB) laptop that recognizes the old man?

    Thanks for all your help!

    Hello

    2.5 hard drives can be bought anywhere I think then, either you contact an authorized service provider or you visit your favorite computer store.

    I think that the Satellite 1900 limits the 28-bit LBA. This would mean that the size of the HARD disk is limited to 128 GB. The maximum capacity is 120 GB that you can use, but I think that 80 GB would be enough according to your amount of files you want to save on the HARD drive.

    If you have any other questions please let us know! :)

  • Satellite C660D-102 blocks when past to the screen saver

    Hello

    I have a Toshiba Satellite C660D-102 of Windows 7 OS. Basically, if my computer is left unattended, and goes to the screen saver, it freezes and has to be restarted by holding down the power button. If I'm listening to the music, makes a loud noise when it does this until it is turned off.

    Anyone has any ideas of what could be the cause?
    Thanks, Matt

    + The message was edited: changed name of the laptop.

    Hi Matt

    To be honest, this laptop T series is unclear to me. What is the correct model name or model number?
    Are you using the original pre-installed OS?
    Have you noticed this problem since the day where we?
    Do you use the standard Windows screensaver?
    Did you install additional software that is running in the background?

    Sorry for these questions but it is not easy to give you simple answer and specifies what may be the problem.

  • Satellite P20-102 - receiver remote not working do not after running recovery CD

    Hello

    I am running Windows Media Center Edition and on my laptop Satellite P20-102.

    I recently needed to run the recovery CD, the process went well except that my box of external remote control receiver provided with my laptop no longer works.

    The box works with XP Media Center Edition and the remote control before I ran the recovery CD. The receiver is detected and installed on the computer when it is connected and recognized in device like a USB Serial Converter Manager. The inner light flashes about 4 seconds. When you press a button on the remote control light both in the housing of the remote control receiver if it receives the signal.

    I guess it's a software problem, I can't find any information on the installation of the receiver or all the drivers for it.

    Any help would be greatly appreciated.

    Kind regards

    Paul

    Hi Paul

    I also P20 but unfortunately without MCE. I can't give you any help, but in my opinion, you should try to contact Toshiba hotline in your country. Maybe it's possible that one phone call can help you manage this matter in the right direction.

  • XP display for Satellite 1900-102 driver

    Hello

    I'm looking for a display driver for my old Toshiba Satellite 1900 102.

    After Installing Win XP Pro, a generic driver for ATI Mobility Radeon was automatically installed, and it is not working properly.

    Refreshing window is very slow and impossible to manage or configure.

    I'm trying to find it but it seems impossible to me.

    Can someone help me please?

    Thank you.

    Kind regards

    Vito

    Hello

    > Refreshing window is very slow and impossible to manage or configure
    The problem is that a graphics driver has not been installed and the Win operating system uses own common Microsoft driver.

    To resolve this problem, you must install the graphics driver of the European driver Toshiba page.

    To find the page of the European driver follow this path;
    http://EU.computers.Toshiba-Europe.com-> support download &-> download drivers

    You have to search the ARCHIVES!

    Good luck
