Z50-70 portable - some keys do not work

So I got a laptop Lenovo Z50-70.

Some of its keys work not at all, not even during startup. I had a portable dual-boot (with 16.04 Ubuntu and Windows 10) and it seems that some of these keys do not work on any of the operating systems installed. Keys that don't work are: z, x, c, v, m, comma, point, enter, return.

What I noticed on this key, they are good at the line at the bottom of the keyboard (except entrance) entire letter.

I tried to take the battery, turn the unit off. Restart with the battery or the power supply. Nothing has worked. Laptop warranty has expired as well.

Laptop 2 years ago. I had a similar problem with the key "1" at the time. But the problem there was that was "press button" permanently. I took, cleaned and still didn't work. Turned out to be working the next day for one reason or another.

Nothing has happened before and after the last use of the laptop. Last night while writing of the code worked well. But in the morning he started to act like that.

Any adivice is welcomed. Thank you!

Everything was OK. I have reset the default BIOS values and still nothing.

I need to change they keyboard it seems.

  • 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

    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 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.

  • 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

    Basically, the other day I noticed the keys 3 and 5 were not work next to the f3 key (meaning I now have to go into the settings of brightness, whenever I want to increase it). I thought "I'll just reboot and see if that fixes anything" and he did... temporarily. I have to restart every time that I've lost the ability to use these keys, but now it does nothing.

    There is no update which should install Windows (updated 8.1 update 1 recently).

    > 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).

  • Natural 4000 ergonomic keyboard that some keys do not work

    I have natural 4000 ergonomic keyboard for about a year now on Vista 32 bit. The keys P, [---],--------do not work (using keyboard on the screen so you may be wondering). Just downloaded and reinstalled the latest drivers and still does not work. It's a software thing or my keyboard was just wrong?

    Any ideas?

    Thank you!

    Hi Savan,

    Thanks for the reply, I would have thought that in a first time. I advanced and tried on a laptop and the same keys still don't work.

    So assuming that the keyboard was already broken, I advanced and open. The fact that I learned a lot about the anatomy of a keyboard. Inside are four layers the rubber part were the keys strike and 3 layers of plastic, so did a quick inspection and noticed some dirt. Used some compressed air blower but the difficult part was cleaning between the 3 layers of plastic, I used a clean and dry cloth in the interval wiping and focusing on letters that were not work. While the keyboard is plugged in so I can test it and see if its working. And guess what, it WORKED. Following cleaning and re-assembled the keyboard. And works very well since.

    I hope this info helps others, sometimes we think air powder top is enough to clean the keyboard, but a few times can get average dirt under these layers of plastic.

    Thank you!

  • HP probook s - 4530: some keys do not work

    Hello, I'm new here and this is my first question. 2 years ago, I bought a HP Laptop G4 1200TX at a local retailer. It worked fine until last year when, manually, to upgrade its window family win7 basic to win7 premuim, then to win7 ultimate. After a while some of the keys stopped working {last line keys - 'z', 'x', 'c', 'v', 'm' (the last alphabets of line except 'b' and 'n') and the space bar has stopped working}. Its been a long time now also the laptop is out of warranty. I have following things havedone:
    (1) uninstalled the keyboard from the Device Manager and then reinstalled again.
    (2) clean the keys by slightly pulling upwards (there was no dust/dirt in all)
    (3) removed the battery and hold the power button for a minute and then reinserted the battery.
    I tried the above methods more than once but without success. I also read your forum for questions and similar responses, but they were the same as above. Its really hard to open the on-screen keyboard every time. Now, I want it to be perfect, more than ever since I had to go to College where the laptop is necessary. If I come to you now help.

    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

    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.
