Satellite Pro L670 - Touchpad Synpatics stops and begins to work

Hello
I'm having a problem with my touchpad that makes me crazy. He suddenly stops responding and then won't work again until I reset the laptop. Sometimes it will take a few reboots or it may not work for the days before suddenly works again for a few hours.
Here are the things I've tried:
-Uninstall the drivers and installing the last
-Reinstallation of Windows 7
-Drive replacement hard (the old one was not)
-Unscrew the laptop computer and the physical connection verification
F keys

Sometimes the device disappears completely from the Device Manager. However, when I view resources by connection, there is a yellow triangle by Synaptics PS/2 Port TouchPad. The State says:
"This device is not present, is not working properly or is not all its drivers installed." (Code 24) ».

Someone at - it any other ideas? The laptop is out of warranty. I think it's maybe a hardware problem, but then I don't understand why it works sometimes and then stops.

Thank you.

Hello

Microsoft says this about the error code 24:

* + Diagnosis: + *.
+ The device does not seem to be present. The problem could be a faulty hardware, removable hardware that is not removed, or a new driver might be needed. Devices to stay in this State if they have been prepared for removal. +

* + Solution: + *.
+ Fill the physical removal of the device. +

In my view this means that the touchpad module is defective or malfunction sometimes starts in my opinion it s no software related problem but hardware.

In my view, that the touchpad module should be replaced usually is a work of a technician for laptop
The warranty is valid? In this case the fix should be made free of charge.

  • On Satellite Pro P300 touchpad has stopped working

  • Satellite Pro L670 - 14 p - stops down, often

    Hello

    My son has an i5 - 430 Pro L670 - 14 p Dual Core running Windows 7 64-bit, which is less than 6 months old. He plays World of Warcraft for several hours at a time and found that the laptop stops after maybe an hour of constant game.

    We bought him this model because we assumed that he could handle him being on various games for hours. Is this a problem with the laptop or should we just tell him to go easier on this subject? Otherwise, if it is quite normal for this model, is there something we can do to upgrade the fan, assuming that it stops overheating cause? When he left he turned off for an hour it can then restart it and start the game again, but the same thing will happen again after some time.

    Thanks, Ric

    Hello

    I imagine your son uses the laptop often enough if he's a player of World of Warcraft ;) so according to me, there is a lot of dust in the cooling modules. This means that you must clean the laptop using jet of compressed air to blow the dust from the cooling fan. It is very easy and only takes 5 minutes, because it s not necessary to disassemble the laptop.

  • Satellite Pro L670 - 11 d and Dynadock U10 problem re-docking station

    This my first post on this forum - I hope I have the right category.

    We have a user with a Satellite Pro L670 - 11 d attached to a port replicator Dynadock U10 USB.

    Everything seems fine, except when press us the disconnect button (or select eject Dock) the laptop leaves the great.
    However when we try to anchor (for example after a meeting of bureau) it does not recognize the usb connection and docking station won't. We usually have to restart at this point. We are attentive to reconnect to the same usb port.

    Has anyone seen this problem and know a fix?

    Thank you

    David

    Hello

    Have you noticed this problem only under this Dynadock U10 or perhaps with the external USB HDD too?
    In my opinion, it sounds a bit like the issue of the BONE and not like the Dynadock question.

    I would recommend this control by using a USB HDD.
    Connect the USB HDD to the USB port as well.
    Then, disconnect the USB HDD and unplug the laptop HARD drive. Reconnect the HARD drive and check if the HARD drive would be connected again.
    If the same thing would happen with HARD drive, you should check the USB port
    Maybe the chipset driver will need to be updated

    But if the HARD drive is raccorderaient ok and if the question does not seem to be using the HARD drive, then, it would be necessary to check the Dynadock maybe reinstall the Dynadock from the software again.

  • Satellite Pro L670 - 14 M and SATA 6 GB/S Support

    Hello

    I recently bought an SSD (Crucial M4) for my Toshiba Satellite Pro L670 - 14M. He behaves well and certainly improves performance. However, when I test my SSD benchmarks, it reaches only about 230 - 260 MB/s reading speeds on sequential when it needs to get up to 500 MB/s as advertised.

    I'm assuming it's because my SSD is running via SATA 3 gb/s, so I ask, my laptop does support SATA 6 Gbps? If not, this isn't a big disappointment, although it would be great to have up to 500 MB/s sequential read speeds for this performance gain.

    Someone can confirm on the question of whether my laptop (Satellite Pro L670 - 14M) supports SATA 6 Gbit/s or not?

    Hello

    The laptop is equipped with a Mobile Intel HM55 Express Chipset and the Intel Core i3 - 330 M processor.

    That's why the SATA II controller agreed that 3 Gbps

  • Satellite Pro A300 - touchpad failed after BIOS update

    After that good BIOS update 2.00 to 2.10 / suggest by ALERT TEMPRO - http://support1.toshiba-tro.de/tedd-files2/0/bios-20091125132031.zip/ the touchpad of my Satellite Pro A300 - GR 1 stopped working.
    He appears under the name hidden in Device Manager. The State of the device - "this device is not present, is not working properly or is not all its drivers installed." (Code 24) "reinstall the driver has no effect of course. I can also access the BIOS utility when you start pressing F2.
    Running Vista Business 32-bit Edition.
    Ideas to solve the problem will be highly appreciated!

    Hello

    Normally, it should be possible access the BIOS, if you press F2, once you have turned on the laptop. Please check again and load the default settings there.
    And you cannot access the BIOS if you shut down the computer.

    You can use an external mouse on the laptop? Please check this too.

    I've also updated the BIOS on my Satellite A300 but I n t have a problem with the touchpad after the update.

  • Satellite Pro L670-103 screen is dark - external monitor ok

    Hello

    Screen goes black in my Satellite Pro L670-103 while playing games. It is not completely off, but very very dark.
    System is activated and works while its happening. No flickering, changing colors.
    On the external monitor (TV via HDMI) everything works fine (so I guess that the GPU is very well).

    The beginning I had to restart the laptop and screen was once again but now it does not work and I have to wait a few more hours a sound goes on again just by itself (im leaving laptop on).

    I only use the approved oryginal drivers.
    System Windows 7 pro 64
    I guessed it might be the display inverter, but someone from the point of laptop repair told me that because my screen is RUN there is no converter and problem is with the screen itself.

    I spent hours reading various forums and UPS has been my best guess.

    Post edited by: Cezar_1

    Hello

    I think that its problem of converter FL.
    The FL inverter controls the backlight of the internal display.
    I think I get m with my suggestions because the external monitor looks ok.
    So it may not be a driver issue not a GPU problem

    Get in touch with the service in your country then must check this part

  • Satellite Pro L670 - 18F PSK3FE Webcam works become "unknown device".

    The * webcam * on my * Satellite Pro L670 - 18F PSK3FE * who is running * Windows 7 64 - Bit * a well worked until this week. My notifications bar started to say * "unknown USB device" * and when when I went to use the webcam it no longer worked.

    When I disabled the webcam in the BIOS the notification has stopped, but when I turned it on the notification came back again to the top. The unknown device is clearly the webcam.

    I updated my BIOS and tried the system restore.

    I also downloaded the driver for the webcam of http://uk.computers.toshiba-europe.com/innovation/download_drivers_bios.jsp?service=UK and have tried running that - + but it NEVER seems to complete the installation. + I have will continue to try to reload the driver and see if that helps, but from now on, I do not think that the pilot will help.

    If it is just a driver problem, someone could suggest how to get the driver to install really :-(

    I am now at a loss. I'm not sure what to do now. Suggestions?... + Please! +

    Hello

    Unknown device means that the driver is not installed.
    I think that the installation of the webcam driver should fix it.

    As face recognition also use the webcam, I recommend you to uninstall this tool as well as the older version of the software of the webcam.
    Both (or just face recognition) should appear in Control Panel-> software

    Now download both applications to the driver page.
    Start with the installation of the webcam driver:
    (1) unpack the webcam driver package

    (2) the TC30049700N.exe may also be decompressed (right click-> extract here)

    (3) now you should see different files exe, dll, and others attempt to run setup.exe to start the installation. If this does not work, go to Device Manager, mark (webcam) unknown USB device and install the driver pointing to the folder that contains the files of webcam driver. The system should automatically recover dll files.

    (4) restart the laptop and follow with face recognition software.

    Good luck

  • New Satellite Pro L670 - 14 M turns on if the charger is plugged?

    Hi all

    New to the forum so grateful for any help on this matter.

    I bought a brand new laptop Satellite Pro L670 - 14 M last week. Now it works fine up until today. The last time that I used it while just running the battery was Monday night. I was working on the laptop, send email etc. today, and I decided to change rooms. For some reason, I still have to discover that I disconnected the charger from the wall (instead of simply unplug the charger from the laptop) so that it was plugged into the laptop and the laptop just turned off much to my shock. It was sparking that I saw the decision-making that I removed the CAP, but now the laptop lights not unless supply current is connected. If I unplug the charger, the computer does not illuminate.

    Now, my first thought is I (crossed beams) killed the battery, but the strange thing is, when the laptop is plugged in and turned on and I'm on my screen and I click on the battery icon in the taskbar it States 94% available (plugged in, load)

    While I wait for some answers I hope I shut down the laptop and leave the charger plugged in to see if the battery has loaded more than 94%

    Hello

    I think that the BIOS update would be worth a try in your case. Take a look at the Toshiba driver download page:
    http://EU.computers.Toshiba-Europe.com/innovation/download_drivers_bios.jsp

    But before you start the update: make sure that you are logged on as administrator and close all running programs. Unzip all files from zip archive first.
    After update successful BIOS load default settings in the BIOS.

    Are you using the original Toshiba battery and AC adapter or they are 3rd parties gone?

    If so - is that this chipset in all series production of the 1 M 3?

    I couldn't find this information on the Toshiba site.

    Thx a lot

    Hey Buddy,

    I agree with the user MannerhagenVPO. The chipset of this model is Intel HM55 Mobile and all the Satellite Pro L670 - 1 M 3 models are equipped with this chipset.

  • Vista drivers for new Satellite Pro L670 - 14L

    So I have been serching for a laptop of decent game and found: Toshiba Satellite Pro L670 - 14L to be a good combination power/price
    but after reading some reviews, I discovered that many people's complaint that the toshiba drivers are not updated.
    that seems to be true because the latest drivers for my P300 with 4500 m are 2008!

    So, I checked for L670 Vista display drivers and did not find one! Even for Win7 do not seem old already,
    is that mean Toshiba is not compatible Vista more? I have to use windows 7 only?

    I can see in the specifications of the laptop your laptop came with WIN7 64 BITS HOME PREMIUM.
    Can you confirm this?

    Why are you asking about the Vista drivers if you got the new OS to Win7. You want to use Vista or what?
    I want to say Win7 is much better than old Vista OS so I put t understand what you exactly want. To use Vista or you ask here for more recent WIn7 display driver?

  • Which hard drive Solid State for Satellite Pro L670?

    I have a Satellite Pro L670, I need to configure for presentation and having to re - load operating system anyway.

    Rather than write the existing drive too much, I thought that it would be best to get a second to adapt instead.
    Replace the current (obsolete) rotation drive with a solid state, it seems to me the best way to go.
    Has anyone equipped with a hard drive to a Satellite Pro?

    For budget reasons, I plan to go for a capacity of 120 GB that will be enough.

    However, I've yet to discover at Toshiba they could recommend. Anyone else gone this route?

    Hello

    Theoretically, any SATA SSD drive should be compatible because the laptop supports a SATA controller.
    But in some cases, it might be possible that an SSD would not be treated properly. In such cases, SDD drive manufacturers provide different firmware updates

    So before buying an SSD drive check the support pages of the manufacturers of SSDS for more details would perhaps have a firmware update
