Satelite C875-1FZ - keys on a keyboard failure

Hello

When I start my Toshiba Satellite C875 1FZ some keys do not work. Usually what I do I open Notepad and press the keys not functional and after awhile, they slowly begin to work again.
I need to continue to use the keys then otherwise these keys "freeze" again.

The keys that bring the question are:

A, b, n, paved digital 7, left s - hift, ctrl, let

Just as now, the keys are working without any problems. Should I stop using them they will seize again.

I already tried the following things:

-Remove the battery and press the power button for 60 seconds and try again but didn t work
-Remove the drivers for keyboard and rebooted but also didn t work.

Would be a great disappointment if I need to return my laptop for maintenance, so I hope you all can help me.

Kind regards
Wesley

I'm quite sure that the key problem is related to the breakdown of keyboard m.
Just to be 100% sure, plug an external USB keyboard and test functionality.
In case the external keyboard should work correctly, the problem is that the internal keyboard and this would need to be replaced.

In case the external keyboard wouldn't work correctly, the controller of the keyboard (part of the motherboard) would be the troublemaker, but I guess that it s not.

  • My Acer Aspire V - 123 Windows 8 keeps freezing and some keys on the keyboard are not working

    I'm currently using a netbook ACER ASPIRE V - 123 with Windows 8 as its operating system and it is not yet updated to 8.1.

    At first when my computer laptop while boots 'seems' to agree, and whenever I try to open a file without any content it took me about 30-45 seconds, opening a program would take me almost 45 seconds to a minute, and I think that something is not right with my laptop and when I try to open a website via my web browser and my laptop would just FREEZE and I can't do anything about it , but I hate to do HARD reset. And to add to this unfortunate scenario is that some of the keys on my keyboard are not working the letters like R, T, I, O and backspace and many others (which I don't remember exactly one by one).

    I try to read some forums on different sites and some posts to the community of MS and did several tests like starting in SAFE MODE w / NETWORKING and downloaded the software like MALWAREBYTES to find potential infections, but nothing found. I also did the start-up in MINIMAL MODE, but again, the situation was the same, but when I'm the boot without failure the filling and freezing are only decrease and I don't want always starts in mode safe.

    From now my laptop is booting in a start-up in MINIMAL MODE and I don't know what to do next, what to try next. I hope someone could lead me to the solution to this problem, I would be eternally GRATEFUL.

    Please do help me in a step by step process and if possible please guide me with pictures or screenshots because I prefer to learn things when I Visual effects on what to do.

    Thanks for patiently reading this post.

    Hi Ben,

    Sorry for the late reply, the laptop has been fixed, it seems to be a hardware problem. We disconnected the connection of the keyboard to the laptop right now I use an external keyboard to type. Cannot afford now to buy and replace my laptop keyboard, the graphics card Driver has been updated also and I've reformatted the OS

    The gel did not appear more in the normal boot and if all goes well for work this way for good.

    Thanks for the information you have shared to me, he has also been a great help.

    until next time Ben!

    Best regards

  • How to set the pressure necessary for the keys on the keyboard? I adjusted it 2 years when I had my Macbook Air, but I forgot how I did it. In my opinion, only a touch of F has been used.

    How to address the need to pressure for keys? I've adjusted it 2 years ago when I got my Macbook, but I forgot how. In my opinion, only a touch of F has been used.

    I don't know what you are referring. You can't 'adjust the need to pressure for the keys. The keyboard is what it is. The key must be pressed far enough for electric contact in key switches. The keys are not adjustable in this way.

  • Satellite X 200-how clean some keys on the keyboard

    Hello.

    I'm looking to remove a portion of each of the keys on my keyboard and clean.
    Some keys are starting to feel 'sticky', and I don't want to be cleaning them up and so on.

    So, I'm having issues actually remove the individual keys. Like a laptop keyboard, I'm doubting you can just 'pop' out the keys with a needle or similar object. So, how do I remove them?

    Quick Edit: as the title suggests, it's the Toshiba X 200.

    Hello

    You mean you want to delete only the caps key?
    Yes it is possible and the caps are glued on the keyboard!

    So you can remove it carefully using a thin object.
    You can out simple plugs with care.

    I did very often to clean the space under the caps of buttons!

  • Satellite Z30-A-1CZ - broken key on the keyboard

    Hello

    I am proud to use a Toshiba Satellite Z30-A-1CZ., I bought this winter in Germany.
    It is a wonderful machine and work or surf is an absolute joy.

    Last week I broke accidentally (left arrow) key on my keyboard.
    The key cap is broken, it does not have to clip, the Clip of withholding key and the Cup rubber are still ok.

    Can you help me, giving a hint, where can I buy new key, while I can appreciate even more the work?
    To return to Germany for the guarantee is not a solution for the moment.

    Now, it's horrible, and working on it is a pain

    I hope that your team can save my key? You are my last hope.

    Best regards

    You can try to contact the ASP from Toshiba in the country where you are resident or currently stay.
    The ASP may be able to provide unique key hats...

    Another idea: visit a few independent computer stores / downtown dealers.

    As I know the keyboard Poretege Z30 uses a key town CAP, editing which should be accompanied by other keyboards...
    then perhaps you could get such a ceiling for another similar keyboard key...

  • Satellite A300-15J - keys on the keyboard

    Hello

    I got my laptop about a week now. I liked it carefully, the brilliant keyboard did irritate me at first, but... But to my surprise... this morning the left low corner command button was loose... it seems that one of the "connectors" broke up.

    Of course, I know what to say, I broke it, and it's probably true, because I type on my computer and so to put pressure on it... BUT, I have a respect for computers, I don't hit my computer and I have typing skills...

    I called a local computer company and they said that I need to replace the entire keyboard... because Toshiba will probably not fix it under warranty because they will say I did damage... I had a toshiba A100 for 2 years, the keyboard still works fine...

    I wonder if anyone has any suggestions or comments on this topic?

    Thank you very much.

    Well... sad story, but the fact is that the key on the keyboard is broken and the keyboard needs to be replaced.
    I don't know why it broke... maybe you used really too much pressure while typing... who knows. ?:|

    I have two Toshiba laptops different... one is 5 years old and the other is about 2 years old and I never noticed any problem keyboard or buttons...

    So in my opinion, you had a bad luck... that's all.

    Good luck with your keyboard replacement...

  • R850-169 - key on the keyboard to replace satellite

    Hi, I dropped my iphone on my laptop (of less than 30cm, I might add) and in some way he hit the right CTRL key and the key on the keyboard is popped! a whole little plastic broke from under the key (the mount under the white key is fine, just the black key is damaged)

    I was basically wondering. Is there anywhere you can get replacement keys for this laptop?

    Theoretically, you can try to find the defective keyboard, remove the button even CAP and set up on your laptop keyboard.
    To be honest I don t think you can buy these caps key as unique pieces.

    Check ebay. Maybe you can find defective or used the keyboard for a few euros.

  • Replace old hard drive with an SSD.  Nowsome keys on the keyboard no longer works.  Ex 'e' and 'b' keys no longer work?  Any idea what could take place in the disc replacement?

    Replace old hard drive with an SSD.  Now some of the keys on the keyboard stopped working.  Ex 'e' and 'b' keys no longer work?  Any idea what could take place in the disc replacement?

    Probably nothing, it's probably a fluke. Try resetting the SMC and the PRAM by iMac Intel SCM and reset the PRAM. If this does not work, try a USB keyboard to test, if it works then your original keyboard has failed and must be replaced.
