temporarily functional keyboard

A virus has infected my computer and in addition I had keyboard problems.  I ran anti-virus and always had keyboard problems.  I installed a new keyboard on my laptop and it worked fine for a while.  Now the computer is not responding to some keys such as the number four and the right shift key.  I got the computer to the State, he left the factory with toshiba recovery disks.   I also reset the bios defaults.  After resetting the bios, the computer responded to the four key.   A few minutes later there no. This explains how the keyboard worked temporarily after resetting the bios.  I tried to replace the bios and uninstall the keyboard driver, but this does not solve the problem.  If I plug in an external keyboard on my laptop, it works.  The only reason why I don't think that the problem comes from my laptop keyboard is because it does not work after the reset of the bios for a short time.

Hello

I suggest you to contact the Toshiba Support for assistance that the problem is with the hardware components.

  • Unable to sign no function keyboard or mouse :(

    I read that many of same issues reported by other participants in their positions, although they appear slightly different, and here's why. I briefly restored function several times simply through the persevering, start SafeMode (sometimes only works). Most of the time but when I try to start my Win7 64 bit PC, the mouse is that are no longer as is the keyboard. They are both wireless and changed the batteries. I suspect a problem in a recent OS update, however, had hoped that I had worked around it through system restore resolves nothing, although I thought it was because he worked for two days. I'm pretty focused on technique (tech appliance business), but still refers to my base of knowledge as a novice when it comes to software.  Help, please.

    Mark,

    We appreciate your efforts on this issue.

  • Re: Gift of functions keyboard FN + F1/12 ' work on Satellite A350

    Hello

    I bought a new laptop Satellite A350 from 13 to about a year with a Win Vista Premium Home (Hungarian) operating system installed on it. It works beautifully.

    Not so long ago, I upgraded to Win 7/32 bit OS (Hungarian) and it seems that I've lost functions FN + F. If I push the FN button with any F key (for example. FN + F6) nothing happens. I can't disable the touchpad or (FN + F9).
    Only two features that reacts with the FN are numbers (FN + F11) and arrows (FN + F10).
    I already checked the Alps Pointing Device driver and it says it works correctly and up-to-date). I also read the Thread of NVIDIA, "Satellite A350 - cannot disable Touchpad post: 17 June 2009 22:11" but I became wiser. I'm probably too blonde for such things. (I would like to apologize in advance for blondes to this note).
    Could you please give me some suggestions.
    A quick response would be appreciated.

    Thank you very much.
    Best regards, surveys

    I agree with the user orevious;
    You need the VAP (value added package) and utility of Flash in order to get memory card Support the FN keys work correctly.

    As the VAP software and card Flash is not portable model bound, you can use the tools available to the other laptop models. for example, Satellite L500

    Good greetings to all members of this forum .

    right, a strange thing, when I turn on my laptop all the keys work fine, then after 3... only 5 minutes from the navigation keys will work. in this case I would restart the laptop, so again, it will work. But also it happens even if I restart it it will not work until the next reboot: s

  • Smart keyboard sometimes does not work

    I have a smart keyboard connected to an iPad 12,9 Pro.

    Sometimes it stops working and I have to restart the iPad be responsive again.

    This is quite annoying because it happens 4 - 5 times a day.

    I think it's a software problem. I look forward to a solution from Apple.

    Hello alessandro2410,

    Thanks to ask questions on your Smart keyboard doesn't work don't not with iPad Pro sometimes. I understand how it is important to have a functional keyboard at any time since everything we do these days is on our devices. I'm happy to check this with you.

    To make sure the Smart keyboard until properly, I want to double check all of this help article: use your Smart with iPad Pro keyboard. If everything is correctly configured, at the end of this article is the section to get help, if there are any questions by using the intelligent keyboard with iPad Pro. If the keyboard stops working, I try to adjust the position of the iPad for a while and then re - implement Type position. I would like to ask some clarifying questions to try to win because of that.

    1. have you setting the position of the iPad for a moment, then put back in the position of Type help or you must go through all the steps, and he only reconnects after restarting the iPad?

    2. when it stops working? You mentioned that it does that 4 or 5 times a day, but it's after the iPad goes to sleep, or after you do not use it for 10 minutes, you can isolate when it no longer works to offer other options?

    3. have you noticed the disconnect keyboard started after 10 iOS upgrade only?

    Please provide information and work with me here in Apple Support communities. Have a great rest of your day.

  • Page Up / Page Down - switches btw scroll/browse functions "Randomly" - NO caret associated

    First - let's make this clear: this is POSITIVEMENT NOT a "KEYBOARD NAVIGATION" problem. Pressing on F7 allows him and the problem persists, by pressing F7 to disable the CB, and it is still FUBAR.

    As the title suggests, the PageUp / PageDown keys do not always work to scroll up and down in a page. When they do not have this function, they work to Back/Forward navigation (alt/alt-right) respectively.

    This seems to happen randomly, but very often. Within a single browsing session he can switch back between the two. Of course, I can't always identify when it switches. Although (and it could be the bias of the observer) I noticed that sometimes some pages seem to enable it (scrolling, i.e.), possibly Wikipedia and Google Image search.

    I tried "Safe Mode"(tous les plugins & extensions désactivées) without change in the results. ""

    Suggestions are welcome - it kills me - it makes my mouse/touchpad and keyboard with both hands navigation method difficult. I also (more than once - including by writing this) lost much a content form (textarea) trying to srcoll on that, I navigate rather 'Back', lose everything.

    Thanks in advance,
    Mark

    Yep - due to an intervention of the shortcut function keyboard ASUS (or Elantek?).

    This thread in the bug report, "dmtf2010" has posted the following solution:

    So, the solution is:
    1. go to about: config
    2. find ui.elantech_gesture_hacks.enabled
    3. change its value from-1 to 0
    4 restart FF
    5. If you encounter a bug this option is designed for difficulty (non-working page by sweeping gestures), install the latest driver Elantech (http://www.techspot.com/drivers/driver/file/information/14513/) and restart.

    Thanks cor - el. This will make my browsing so much better.
    Select this option.

  • Questions from the screen and keyboard on Satellite R830-181

    Hello

    I had exactly the same problem with it;
    http://forums.computers.Toshiba-Europe.com/forums/thread.jspa?MessageID=280934

    I also explained what is it and how it over time in this topic.

    To sum up; my screen and keyboard do not work in my Toshiba Satellite R830-181, 13.3 '' laptop.

    My questions;
    1. is it a motherboard problem?

    2. as it runs on an external monitor, I guess that the graphics card or processor is fine.
    There is no damage on the screen, so I guess there is a problem with the connection of the power supply to the screen.

    If I buy a new screen I have my doubts it will work.

    I'll probably send it to the service tech in my country (hard to find here reliable technology services Toshiba), however, I would like to know what may be the cause and if I can fix it myself.

    What do you think guys? It is a power issue or a problem with the monitor itself?
    If a power issue or something else rather than the screen, how can be fixed?
    Same question applies to the keyboard.

    3. If I repair or fix myself, you think it will happen again? Because I think that this could be a faulty laptop computer of a certain series of production since someone else has experienced the same thing with this model.

    can 4 - there be a relationship between the non-functional keyboard and screen?

    5. If this can be resolved with a replacement of the screen, that I need to find a laptop screen Toshiba R830 or I can buy any 13.3-inch screen?

    As far as I know this model is not supported by the company more, so it is quite difficult to find a screen R830.
    It is difficult to find a 13.3-inch screen, anyway, but still, if I can use the screen of another model which would ease my problems.

    I need an idea on that.
    Thanks :)

    > 1 - is it a motherboard problem?
    Not easy to say: If the external monitor works correctly then this isn't problem chart/motherboard.
    The external USB keyboard works properly, if not motherboard problem too.

    > 2 - because it works on a monitor external I guess graphics card or processor is fine.
    Yes, that's correct.

    > If I buy a new screen I have my doubts it will work.
    I do not recommend to buy the new parts before the defective parts has not been verified.

    > I'll probably send it to the service tech in my country (hard to find here reliable technology services Toshiba), however, I would like to know what may be the cause and if I can fix it myself.
    Good idea to send it to Toshiba service partner since the guys would be able to control parts and fix it.

    > What do you think guys? It is a power issue or a problem with the monitor itself?
    If a power issue or something else rather than the screen, how can be fixed?
    > Same question goes for the keyboard.

    Don t think someone can tell exactly what's causing this according to me its just a bad luck material can start malfunction happens in every possible branch of industries (TV, computer, smartphone, cars)

    can > 4 - there be a relationship between the non-functional keyboard and screen?
    No, the keyboard is only connected to the motherboard, display is also connected to the motherboard, but there is no connection between the keyboard and the display.

  • Satellite Pro A300D - what is the model number for the keyboard?

    My husband managed to dislodge a key on my keyboard CAP and broke the clip white scissors that holds up on... (don't ask me how)

    He spoke of the authorized service center here in Norway and they sent us replacement scissors tongs (actually they sent an old non-functional keyboard), but the clips are of a different design to those on my laptop.

    I was wondering if anyone has an idea of the model/serial number of the keyboard used in the Satellite Pro A300D-151 (PSAK9E) so I can get the correct replacement part.

    I really don't want to have to replace the entire keyboard when it's just 1 scissor clips which is broken... the laptop is only 5 months old.

    Here are some pictures of the scissors clamp in question and where it attaches to the keyboard (sorry for quality)

    Hello

    Boyfriend sorry but it is not possible to exchange a few individual keys on a keyboard, so in this case, you must replace the full keyboard. But normally, it shouldn't be so difficult.
    Either you exchange the keyboard yourself or you sent the laptop to the authorized service provider.

    The model number for the keyboard is not known to me but contact your ASP! They can order all the parts of Toshiba and they should know the right part number.

    Good bye

    Thanks in advance for helping me wit HCet problem. I have a bought Y550 a few years back (read as out of warranty). It was shipped with Windows Vista and has been working well (especially) since I've owned it. I decided to upgrade to Windows 7, bought the upgrade software and run the upgrade.

    Following the upgrade, the keys do not work correctly. IF blocking issue is not engaged, no button works. If I commit number lock, keys working 7-0, but then the rest functions keyboard oddly. I restarted the computer in safe mode, and the keyboard works perfectly fine in safe mode.

    I guess it's a disk problem and not hardware related. The thing is, I seem to have the most up-to-date synaptic drivers loaded the Win7 upgrade.

    This is a strange problem and I hope that something that some people have seen. It made the laptop pretty unusable - numbers are important quite rudely...

    Thanks for any help,
