EliteBook 8570w: strange keyboard on Elitebook 8570w acting

Hello

I recently acquired a 8570w here, but there is something wrong with the keyboard. The thing is that when I hit the 'z' key, he recorded "zn", goes the same for 'r', which records "rq". If certain keys wrote 2 letters if I press one or the other. I already tried latstes bios decommissioning and replacement of the keyboard with another. The problem also exists in the bios, so is not associated with Windows, and an external keyboard works fine. It is safe to say that it is a hardware problem? Or does anyone have the tip Golden for me...

Thank you!

    Start safe mode and see if there are still have the problem there. Safe mode is slow and some things do not work, but it prevents some third-party boot loading software. If your keyboard works properly in Mode without fail, this would imply that some third-party software is causing the problem. If so, check the updates.

  • Satellite L750D - issue strange keyboard/touchpad

    Hi guys, I'm new here and I hope you can help me.

    I have a Satellite L750D here who has a strange keyboard/touchpad issue.

    Recently, my screen was replaced and I toke the possibility of replacing the DD by a SDS.

    I used the OS restore cd that I created from the partition recovery and completely reinstalled Windows 7 64 - Bit ones.

    Everything seemed to work well after the last restart.

    Then my after reboot, the keyboard was not working and or the touchpad.
    I tried to restart / stop and start again, no change.

    I plugged a USB keyboard and mouse, both work perfectly.

    I reinstalled the drivers of touchpad on Toshiba site, still no change.

    Then, I closed the lid and leave Notepad go into sleepmode/setting standby extended and found that when I opened the lid/screen, the keyboard was working again, but not the touchpad.

    Fn + F9 made no difference.

    I then pressed the button above the touchpad, but the touchpad remained dead. But after pressing this button, the keyboard went dead too!
    The key for the touchpad power made no difference, the keyboard or the touchpad remained dead.

    Given zero made no difference either.

    Throw the drivers in safe mode led the pilots to be reinstalled, but both keyboard and the touchpad remained dead.

    The only thing to bring back the keyboard is the cover and goes sleepmode/setting to Hibernate and wake up to the laptop.

    But press the button above the keyboard and the touchpad is dead again.

    Started from a Windows 7-LIVE CD, both keyboard and the touchpad remained dead.
    Started from a live CD of Ubuntu Linux, keyboard works, no mather, you press the button for the touchpad, but the touchpad
    died.

    Is there anything else I can try, or what I have to assume there's something defect requiring hardware repair/replacement?

    Thanks in advance for your help.

    Kind regards

    I plugged a USB keyboard and mouse, both work perfectly.

    It's really strange... from my point of view of the rare, the mouse and external keyboard works properly, then the controller should be OK, and this means that the anomaly must be linked to the defective keyboard / touchpad.

    But on the other hand, you said that the keyboard works correctly starting Linux Live CD.
    For me, it makes no sense and I'm confused...

    Anyway, given that the laptop has been disassembled to replace the screen and other parties, I think that something went wrong during this process and probably a part has been affected...

    In my opinion, it is advisable to replace the keyboard and to check if it will fix the problem.

  • Strange keyboard problem - Portege A100

    I have a Portege A100 some three years now.
    There is a problem with the keyboard, only the keys 5tgb - a diagonal line.
    As soon as the PC is often placed on these keys don't work at all. After a while, if I press hard, especially if I turn on caps lock shift, the key to start work and then more or less work. Sometimes turning the PC and trie still the problem using shift often makes it worse. Sometimes the keys work, but only with a delay. No other keys are affected.
    I am confused as to if it's a hardware problem (are these keys connected even if a single connector?) or a strange software problem, perhaps related to the traditional Chinese microsoft input method editor that I recently downloaded.

    Any help or advice would be welcome.

    Alan Watson

    Hello

    The keys are connected on the map as the rest of the keyboard keys.
    There are not connected separately. To me, it looks like a hardware would be malfunctions.
    Why? Well, it's not easy to say. Sometimes loses keyboard cable affects the use of the keyboard. But maybe the entire keyboard needs to be replaced.

    We must consider this possibility I think you should contact the ASP in your country. If the warranty is valid replacement should be done for free.

  • Tecra S1 and strange keyboard problem

    Hello

    I had one laptop Tecra S1 old but still works perfectly, except for one thing that is a few years old.

    A month ago or so the keyboard started acting all weird for a small period. When I press 'e' the output is eo and if I hold down the button the output looks like this: "eooooooooooooo." The other keys work fine. When I press the 'o' key it simply prints me an o. It has nothing to do with the language of the combination Fn + F10-11 settings. When I have the keypad and I press 'e' I just get the number 6, the same thing happens when I press o.

    So basically the o - key works as it should. But there is something missed on 'e '. Earlier today it has worked when I had the pad on, but a little later he returned all crazy. I started my system with a Linux LiveCD to see if it was an OS problem but it wasn't. With an external keyboard, the system works like a charm.

    That one key, the e, causing me a headache. It prints me eo or eooooooooooo when pressed.

    Thanks if anyone can help me with this. I am thinking of opening up the system and check on the keyboard. It is simply difficult to find a keyboard with a layout of the Finns, but maybe I'll buy an English and Relabel upward.

    I agree with the user who has the funny nickname I like it ;)

    It looks like a malfunction of the keyboard and it should be replaced
    The ASP can do this! Ask if the technicians for assistance!

    Hello

    After reassembling the individual keys on my keyboard in Tecra 8000, the keys have a strange behavior. For example, if I press the 2 key the display shows '82' or 'q '. If I hold the button longer, the display shows "2222222222222...", the right to sign for the key. "
    You know, what can I do?

    Hello

    I agree with Daniel. There is a technical problem and the only thing you can do is to try to clean the contacts. If there is no success, you need to replace the keyboard. This unit is older and I am sure you can find a used keyboard at low prices.

    Good bye

  • Strange keyboard on Satellite M40 problems

    My Toshiba M40 has been giving me problems keyboard quite frequently. I funny characters like NB¬A
    When I press the left SHIFT key and then the keyboard starts abnormal behavior:

    1. He moved to uppercase mode - to type letters more low, I actually have to use the caps lock.
    2. I can't use the SHIFT key to type the special characters figures.
    3. by clicking on the menu bar gives me a different effect, as if the SHIFT key is down already as it is not.
    4. press the button right shift takes me to the "Save" option
    5. I can't select a file or folder as several of them selected at the same time.

    And then let fall, shut down the computer (it does not restart at this time)
    After a while, the computer starts normally, but I'm never sure when it will start to behave badly again.
    Read about the update of the bios, so I got mine upgraded to version 1.7 of the toshiba Web site (this is the most recent they had for machines with ATI graphics card).
    Sometimes, I use an external keyboard when the problem occurs repeatedly.

    would appreciate advice on how to overcome this software / hardware problem.

    Hey Ashok,

    It is not easy to say what is causing this strange behavior, especially since it also occurs with an external keyboard. One clue is that the laptop does not restart once you stop it unless leave you for a short period. This suggests that the unit is overheating and that it may well have an impact on the unit that is causing your problems.

    I suggest that you try to give the laptop a clean to remove any accumulation of dust and debris from radiator CPU.

    Kind regards

    You seem to be pressing the NumLock key. On an English keyboard, it can be reported Num, Num Lk, digital or similar. You should be able to turn it off by pressing it again. If this does not work, try to press it by pressing the Fn. consult the manual of your computer for more information.

    Hello!

    I have a problem with my Satellite A300D: when I press on 'y' or '5', I get a "y5" and when I press "n" or "b", I get a "nb".
    If I hold down y or 5, it seems y5yyy... and with n and b I get nbnnn...

    What you think could be the problem? Keyboard? Or some other hardware controller?

    Thanks in advance.

    Hello

    It is difficult to say why this happens, but in your case I would like to connect an external keyboard and check this. You may notice the same behavior?

    If not, I think the case is clear: your keyboard internal doesn t work properly and you need a new. Therefore, you can contact a service provider authorized in your country.

    By the way: have you checked the keyboard input language?

    Are you sure it s only a problem of keyboard and not a corrupted Windows OS?
    The hardware malfunction keyboard is possible that something similar happened on my laptop s a friend. The whole notebook was not accessible because the mouse cursor has jumped on the screen and it was possible to do something
    Finally, EPA has replaced the entire keyboard and solved this problem

    I m not 100% sure if your keyboard is faulty. I think that the new installation of operating system recovery CD is necessary to ensure that it is a hardware or software problem.

    If the same will appear after using the recovery CD then it s definitely a hardware problem and the part must be replaced!

  • Strange keyboard on my Satellite 2450 problem

    Maybe it's only one loses the keyboard cable but it's only a sugestion.
    Unfortunately, I don't think that you will be able to solve this problem without any help.
    I think you should ask the Toshiba service partner in your country for assistance and advice.
