Satellite L50-B-127 - some keys are not working and touchpad blocks constantly

Before leave here an apology because I'm Portuguese and my English level is very low.

My computer is a Toshiba Satellite L50 B 127

Lately, I noticed some anomalies which appeared me on my computer (which should take about a year). When I speak of anomalies refer to the keys you use rarely, and at this stage do not work (example: arrow left, Z,...)
Not to mention that I noticed that my touchpad is constantly blocking, that is to say after the buttons to work, the cursor does not move, being sometimes more than 20 seconds to wait for the cursor to return to normal.

If anyone has had this problem or knows the cause and the solution? Recognizing a response as soon as possible

Hello everyone, I'm here to post my problem that has caused me a lot of problems and troubles and especially apologize because that throughout this text should meet several errors since my English level is low

My computer is a toshiba satellite L50 B 127 and has a little more than a year of use

Lately, I found some anomalies in my computer including some keys from one day to the other crashed, these keys are not widely used (arrow to the left, z, dash). In addition, my touchpad has been constantly block of minutes in minutes, even if the buttons on the touchpad still work, the truth is that the block cursor for a few seconds and then comes back to work as if nothing had happened. In 10 minutes, however this situation occurred four times

I would be grateful if someone knew the reason why this happens or even the solution to answer me as soon as possible

    > I asked this question on the Microsoft forums and I've learned to run the troubleshooter of material (did not help) and if defective, to search for the latest drivers for keyboard - I seem to have the most recent for my model, as from Toshiba Web site does not list the keyboard updates.

    It seems that this opinion is not from Microsoft staff, but some users of the forum.
    You should know that the drivers of keyboard (developed by Microsoft) are still part of the Windows System. Any Windows OS you use, the keyboard driver would be always installed as part of the OS. This means that the drivers of special keyboard DON T exist but system uses own driver...

    You can check the functionality of the keyboard in USB external keyboard.
    If external keyboard works properly, the internal keyboard is malfunctioning and must be replaced.

    If the external keyboard does not work properly too, then I recommend you to recover the laptop using Toshiba HDD recovery. Otherwise, there could be question of motherboard (keyboard controller).

  • Satellite Pro M50 (PSM55E-001001EN) - some keys are not working

    Hi all

    Ive had a problem with my keyboard on the above model. Initially I thought it was just the keyboard, so I bought another one and installed it and it did the same thing.

    Problem:-r button and there does not initially new keyboard works not at all just by typing randomly!

    This could be an internal problem or I just bought a duff keyboard?

    Thanks in advance for your help.

    Tim

    Have you tried with an external keyboard?

    To be honest, I think that there is something wrong the keyboard, but you can check with the outside.
    In the worst case the internal keyboard should be exchanged.

    Keyboard problem?

    Hello

    I got a laptop HP with windows 7, I removed the hardrive and put it directly into another laptop. All except 3 or 4 keys on the most recent work. I think it's because they are different models, how can I reset the settings or drivers for the keyboard?

    Thank you!

    Hello Castingman,

    Please keep us updated on the status of the issue.

    However, before I would need some information to help you best.

    1. What is the brand and model of the keyboard?

    2. the problem occurs with another keyboard?

    I suggest you try the following methods:

    Method 1:

    Try to use this keyboard on another computer and see if the problem exists. This will help determine if the problem is the keyboard or computer.

    If the problem disappears with another keyboard and occurs on the other computer with the keyboard, so the keyboard is defective and must be replaced.  If the new keyboard also has the same problem, then it's probably something with the computer and not the keyboard.

    Method 2:

    Log on to the computer manufacturer website and update the latest chipset drivers and other updates to the device driver.

    Hope the helps of information. Let us know if you need help with Windows related issues. We will be happy to help you.

    Thank you

  • some keys do not work on laptop

    some keys do not work on the laptop.

    Hello

    Maybe it's a hardware problem, but it is always worth trying the following.

    Shut down the laptop, unplug the AC adapter and then remove the battery.  Press and hold the Power button for 30 seconds.  Reinsert the battery and plug in the AC adapter.

    Robinet tap away at the key esc that you start the computer to launch the Start Menu, and then select f10 to open the bios menu.  Press f5 to load the default values (sometimes it's f9, but the menu below indicates the correct key), use the arrow keys to select 'Yes' and press ENTER.  Press f10 to save the setting and still use the arrow keys to select 'Yes' and press on enter.

    Kind regards

    Following problem.
    Some of my keys will not work... nothing has been spilled on it because I refuse to let any liquid near him by fear of death...
    Keys that don't work are the Z, R, Y, the arrow keys, press FN and the /? button.
    It used to work and now it is not a site suggested that I press FN and press the f11 key.

    I did and it would work for about 5 minutes and then nothing... now the FN function not and im so confused and angry... it is my laptop for college and it really hurts when I have to use the mouse to click on the screen keyboard all the time... help plz

    Hello

    The A205-S5843 belongs to the American TV series.
    I checked the hardware specs for the Toshiba page and it seems that this laptop was equipped with the Atheros 802.11 wireless LAN card b/g.

    The Atheros Wlan driver can be downloaded from the Toshiba driver page we or this portal of Toshiba Europe WLan:
    http://APS2.toshiba-tro.de/WLAN/

    Regarding your problem of keyboard/button.
    You guarantee that this is not a software problem?
    I want to say have you tested if the keys/keyboard of laptop s works with the original image of Toshiba OS preinstalled?

    In my opinion this behavior strange keyboard looks more hardware issue more software problem, but it s worth it to check if the new facility would solve your problem
    But if you see any improvements then the keyboard should be checked by an authorized partner.

  • Some keys do not work on my laptop Satellite C

    because today, I have some problems with some keys on my keyboard, my Z-(left next to the Z) and my FN key is not working (I had to copy and paste the XD Z) but this problem is really annoying is there a way to fix this?

    It is unclear to me that the simple keys to repair can be performed.
    In this case, the entire keyboard must be replaced.

    I put t know which model of laptop and how old there but it is possible that some of the keys are broken.
    What you can try is to remove the check and cap - keys if key is dirty and see if there is a contact problem.

  • Some files in my USB SanDisk 16 GB USB key are not detected and when I connect to another PC, all files are detected

    Original title: some files in my USB are not detected and the rest of the files show find when I connect to my pc, when I connect to another pc the files seems to find.

    Hello world

    I have a SanDisk USB 16 G with important files, when I connect to my pc windows 7, some files are discovered, I am able to read other files show as empty files and my pc don't its not able to open them.

    When I connect the same USB for my lap top with windows 8 all the files where to find and I can open with a problem.

    Can some body please help me solve this problem?

    Hi Martin,

    This problem can be caused if the program for the particular file could not be installed on your computer.

    1. What is the file format or the extension of the files that you do not read or recognize in Windows 7?

    2. what exactly happens when you try to open empty files?

    3. have you made any recent hardware or exchange of software on your computer before the show?

    You need to check the files that are not open in Windows 7 and trying to install the software for files that are not opening and control.

    Let us know the status of the issue. If you need help, please after return. We will be happy to help you.

  • Some keys do not work in Satellite C850-B374 bought in April 2013

    [I noticed that the BACKSPACE key and] support key and + = equal to the key, enter key does not work. It did not work when I bought the pc.

    These keys were not working from the moment that I bought the computer. This is a drawback that I can't use the BACKSPACE key.
    How to activate these keys in this laptop?

    > It did not work when I bought the pc.
    Why do you keep cell phone if there is a problem? In this case, you must ask for the replacement and exchange it.
    In any case, contact the nearest Toshiba service provider and ask for help. They must check the functionality of the keyboard and in the worst cases swap the keyboard.

    To be honest, I can't imagine that there is a software related problem. All you can do is check if the new BIOS update is available or reinstall OS to see if this will help. In my opinion you should not do this. Laptop is new with warranty for Toshiba service should fix this for free of course.
