Satellite C660 - keyboard problem

I have a problem with the keyboard on my Satellite c660 laptop, reference number: PSC1LE.
The best way I can describe it is like a stuttering problem because it comes and go (very well for a few hours, then not for a short period).

The problem is that, for reasons unknown to me, I continue to experience a problem where the A, N and Enter keys do not work when you press. Sometimes pressing the key several times (they they are not frozen) is simply the letter out, but I can not continue to press the time key to five or six to get a letter. Just to mention, I've not spilled anything on the keyboard.

I did full virus and spyware scans but have found no problem.
I have done tonight all the updates of windows available to me, but it does not appear to have done the trick.

After the restart that follows the device updates all worked them for about 15 minutes, so that the same three keys stopped working again. On this occasion, it lasted only a few minutes, and now I'm writing this with the same keyboard.

Note: I do not use the original keyboard. I changed the jury due to minor property damage, but he did private.
However, this was done most of the year there and worked flawlessly since installation, until this new edition took place in recent weeks.

If anyone has new recommendations or suggestions as to what can be the cause or solutions and then share it please.

I think you'd understand that nobody is able to say why your keyboard malfunctioned.
Only if the hardware of the laptop has been scanned/verified, it would be possible to say what's wrong here
But as General, there is a good workaround solution to diagnose the problem.

You could connect the external USB keyboard to the laptop and could check if the same problems with the mentioned buttons will occur.

In case the external USB keyboard would work correctly, I think that your internal keyboard is the troublemaker in such a case, you will need to replace the keyboard once more.

  • Satellite C660 keyboard does not

    My keyboard has stopped working and after trying different things I've read in other forums I've went ahead and replaced it. New keyboard was working perfectly until now that all came back but slightly different...

    Original keyboard wouldn't let me type any numbers and letters, v, b, n, f, g, h, r, t, y, were dead, as well as the entire line of F1 to F10. The new keyboard worked perfectly, but now the mouse pad does not work and I get extra letters when I type 'R', I get r5y78 instead... ""vm"rather than m and fh rather than h...

    I don't know if it's a motherboard problem, but it's very strange that the usb keyboard and mouse work fine however new keyboard worked fine for about a week and now I use USB keyboard again...

    Thanks in advance!

    Hello

    If the external USB keyboard works correctly, the keyboard controller should be OK. So I don't think his problem of motherbaord.
    I guess the new keyboard is too bad and you will need to get another try and you need to replace the keyboard once more.

  • Satellite C660 keyboard and mouse not working not

    I have a Satellite C660 who is about to leave the window.

    USB mouse and keyboard do not work (but light up with power)
    He likes also turn off randomly when the battery in but it's the least problems.

    any ideas as to why he did this and what can we do about it will be highly appreciated.

    Thank you.

    Hello

    I m wondering about your statement about external USB mouse and keyboard.
    I thought that your problem has been linked to the defective module internal keyboard and touchpad, but now I m thinking that this may not be the case since the external USB keyboard does not work as well as the external USB mouse.

    Probably his most serious hardware malfunction: maybe something related to the motherboard? Who knows a hardware diagnostic test must be done to confirm this

    Just a question: are you able to access the BIOS? I mean the key F2 keyboard works in order to access the BIOS?

  • Re: Satellite C660 - keyboard and touchpad are not working

    Satellite C660 - 28H

    Win7 64 bit

    Kaskpersky antivirus deleted the file 'system32/driver/cekbfilter.sys' for reason of keylogger (Kaspersky Support says error of file anti-virus, Kaspersky is not virus or virused), and after I restarted OS I find keyboard and touchpad not working do not at all.

    Also I already asked to [US Toshiba Forum | http://forums.toshiba.com/t5/Keyboards-Touchpads/satellite-c660-cekbfilter-sys-deleted-and-no-keyboard/td-p/364673] and he has been Advisor to ask here also

    I can't use Windows recovery (have no recovery point) and I don't want full recovery of factory default - there are many flexible and personal data stored.

    So here how to get the drivers? As I have already said to US Toshiba Forum - I already tried to delete the driver of pad touch and installation of synaptic official site and I haven't changed anything.

    I also think that antivirus can remove not only the file, but some patches to remove the pilot "wrone.

    Eh, it's very stupid situation now. I never had such problems, but it will be interesting to find solution to this.

    Have you tried to connect a mouse outside, just to see if this can work? I want to say that it is much easier to use Windows with the mouse and choose different options.

    If it works, try to open the Device Manager and properties for the keyboard. You will find the option to update the driver. Check if you can find some update driver. The keyboard uses the standard Microsoft so f driver, you may be in line that some drivers are.

    Of course the best solution and easiest for you is recovery facility. If you don t want to do this try to find right drivers using this driver update option.

    One last thing: If you have a lot if important saved on the HARD disk you can remove your laptop and plug it into the other PC / laptop as external device and make a backup. After doing this you can install the recovery image and the problem is solved.

  • Satellite C660 - keyboard does not work but the Num and caps lock shift are on

    I have a Satellite C660 which was working fine this morning. When I came home from work and he turned, the keyboard does not work and therefore can not enter my login information.
    The Num and caps lock shift are turned on.

    Any ideas on how to solve this problem?

    Hello

    You are able to disable the CapsLock and NumLock?
    You can access the BIOS by pressing F2 by turning on the device?

    If this does not work, I would recommend checking an external USB keyboard.
    If the USB keyboard would be functions, then this means that the internal keyboard is defective and must be replaced.

  • Satellite C660 - screen problem

    When my wife got off the plane a luggage handler helped pushing his mother in wheelchair and dragging one of the bags behind him allowing my wife to take care of the rest of the luggage. Unfortunately, the laptop that sat on that bag decided that he didn't like the ride, he jumped the bag and tried to get into the terminal under its own power from the battery.

    There is no visible damage to the laptop as it was inside the bag and no crack or anything on the screen. When turn on the laptop, the screen may remain empty, flicker or it shows the log on and office but instead of white to white, it displays a purple rose, only showing not ecru is affected. Other colors appear correctly although they look as if the display is set to 256 colors or the use of the wrong driver.

    I plugged an external monitor to it and that works very well with the color. If the computer laptop screen flickers a light tap at the back of it he still will get, but the color is not corrected. I think it may be just a loose connection or wire cut between the screen and the motherboard but don't know if the color change would be caused by the present.

    Satellite C660 (PSC1LA-00J001) looks brand new, but I don't think it would be useful to take to get fixed.

    Any ideas on what could be the problem?

    It took me 2 1/2 hours to post this same exact message because somewhere in there is profanity or inappropriate language. :(

    Hello

    On this virtual path, it is not possible to say with certainty what the problem is here. Your laptop must be disassembled and all should be checked. Graphics card seems to be OK, so it must be a problem with connectors, cable or with the screen itself.
    > Satellite C660 (PSC1LA-00J001) looks brand new, but I don't think it would be useful to take to get fixed.
    Why not? Same display exchange is not so problematic. Googling around you will find many online stores where you can order the new display, if necessary. Even on eBay you can get it at reasonable price.

    If you do not have experience with this kind of things I recommend you contact the closest to the Toshiba service provider or some independent IT service and ask for help. Check what options are available and how much you have to pay for the repair.

  • Satellite C660 - touchpad problems

    Hello

    I have problems with the touchpad on my Satellite C660. I have only had it for about 2 & 1/2 months, and the problem seems to be worse.

    I tried to check for drivers, changing the settings of the touchpad, but nothing helped.
    The main problem is that when you move your finger on the pad, the cursor will not move, however it also scrolls the page more or less important size.

    I'm quite frustrated because it is essentially a new machine.

    Everyone has ideas, or should I try to get replaced by a new one.

    Thank you

    James

    Looks like you're triggering gestures. For example, if you press the right side of the touchpad, it will allow the scroll bar.

    You can disable these features in the advanced Touchpad settings.

  • Satellite Pro C660 - keyboard problems

    This issue is one for computer laptop Toshiba Satellite Pro C660-1UX running Windows 7 Home Premium Service Pack 1.

    Some of the keys on Board (E, T, U, I, O, A, B, N, and the Enter key) fail to register.
    All keys tested so far seem to register normally.

    When you connect an external USB keyboard, all the keys work properly. When you use the integrated keyboard or external USB keyboard, however, pressed some key is selected for about 2-3 seconds so that his character register. This makes typing incredibly slow and is naturally unacceptable.

    I checked the Manager of devices looking for errors, but can't find one. The keyboard driver is classified properly installed and functional, and driver update indicates that the latest version is in already in service.

    I've also scanned for viruses using Spybot and Malware bytes and also with laptops own antivirus software pre-installed. All the analyses of the entire system refer a none found the message of threat.

    I read that the keyboards on these machines can sometimes be problematic, which could respond only to edge, some function keys. The fact that all the external USB keyboard keys work seems to confirm this. However, the fact that the keyboard both onboard and external is affected by the same slow pressure might also suggest a bios problem - but that this laptop computer is several years old and working perfectly, why bios suddenly would cause this problem.

    I visited the Toshiba site and based on this laptop with the part number: PSC0ME-02100SEN, I have concluded (rightly or wrongly) that the correct bios download version is 1, 70 - WIN, only when I read the following installation instructions http://aps2.toshiba-tro.de/kb0/HTD9502M10000R01.htm bios
    I became quite concerned, like installing the bios update seems far from simple.

    Does anyone know if it is possible to download and install the bios right through an update automated versus manual download and installation step by step, which, if not carried out as planned, could make the laptop completely unusable.

    Has anyone reading this post experienced similar problems with this make and model laptop and was able to return successfully to the good operating condition. If so, how?

    All constructive advice would be welcome.

    > When you connect an external USB keyboard, all keys work correctly.

    This means that the keyboard controller is OK and the internal keyboard is defective.
    To resolve this problem of keyboard, internal keyboard needs to be replaced.

    > However, the fact that the keyboard on board as external is affected by the same keypress slow could also suggest a bios problem - but this laptop computer is several years old and works perfectly, why bios suddenly would cause this problem.

    Hmm I n t think so
    The keyboard delay can be bound to parameters.
    You can check this in the control panel-> keyboard
