    Some people said you had a problem with any of the mobile world?
    .. .hmm statement very interesting but according to her simple nonsense.

    First of all every part is covered by the warranty s notebook. Standard warranty covers material for the first month issues 12. Of course, it is possible to extend this warranty

    In case the material part will begin a malfunction within this period, the part will be replaced in the warranty conditions. Otherwise if your warranty isn't valid more and you will pay for the replacement of equipment.

    In my opinion, the material must be checked properly to get information what part is malfunctioning.
    Maybe it s just a defect of operation of the keyboard or in the worst case, the motherboard
    It is difficult to say what's wrong so far in the part was checked.

    In case the external keyboard still works correctly, the card mother isn t touched and the new keyboard should solve the problem.

    It's very strange. Unfortunately I have no precise explanation. I suggest you check this with external keyboard to see if the keyboard is not defective.

  • Satellite A300 - 1 5: keyboard and touchpad not working

    I have problem with keyboard and touchpad. Laptop satellite A300 - 1 5

    I have Vista home premium and when I turn on the computer, I put password in the user box then my keyboard and the touchpad do not work.

    In the Bios my keyboard work but when Vista starts it doesn't have.

    How to solve this problem?

    Thank you!

    Hello

    First of all, please check the status of the device in Device Manager.
    Please check if the keyboard and touchpad are listed correctly without any yellow exclamation point.

    But you should try to reinstall the drivers again, even if the keyboard and the touchpad have been recognized correctly.
    In this case I recommend to remove the keyboard and the touchpad Device Manager, and then you must restart the computer once more.

    After Vista has restarted the two devices should be recognized again and should work.

    Please check this!

    Hello

    Looks like I found the solution! I recently came across another post on this forum, where user reported his g5050 showing similar symptoms as mine. A lenovo admin had suggested that it might be due to overage charges stored on the laptop, causing the whole f on the keyboard and the touchpad to act as its loosely connected.

    Solution:

    As soon as I find my cell phone charged, immediately I removed the seizure of power enter the laptop!

    And now, its all working fine!

After disabling laptop and put on 30 minutes, 1 hour or 6 hours, problem exists always again :(

    Then I reinstalled the system of zero, use, update to the latest drivers and issues is always present. I tried this 3 times, but I have no idea what to do. Sometimes when I close the lid of my laptop and later at the output of the keyboard and the touchpad of stand by are frozen.

    Laptop have guaranteed but last time, replaced service card motherboard and CPU. Laptop may be defective?

    Thnx and sorry for the gramatic mistakes

    Hello

    > graphic driver cannot initialize, keyboard is not working and touchpad is froozen. In this situation, I can use external USB mouse and keyboard, Internet (WLAN, LAN), Sound.
    For me, it sounds like that just internal peripheral input (keyboard and touchpad) don t work more and they need to be replaced.
    What do you think about this?

    You can contact your authorized service provider. They can exchange the two parts for you.
    Check this box!

    Regarding your display driver problem, you must update the driver and install the latest version of the BIOS.

  • Satellite A300-1AL - keyboard and touchpad issues after change of OS

    Hello

    I'm looking for suggestions or ideas how to deal with the problem of keyboard and the touchpad, which occurred just after I installed the new operating system. I changed from Windows Vista to Windows 7 and my keyboard and touchpad become inactive after a few minutes of starting the system. It is not serious if I write something or not, the unit works for a short time, then turn off automatically. I tried to find updates the driver but failed to come through what might be the solution. It is difficult to work with the screen keyboard so I hope that you will be able to help me.

    Thank you in advance,
    perkit

    I have Satellite A300-1LI and I installed clean Win7 32-bit using the Microsoft installation disc and all devices are working properly including the keyboard and the touchpad.

    Have you installed Win7 upgrade or clean the Win7 version?
    Have you used Microsoft installation CD?
    In General, keyboard and touchpad must work without any additional driver.

  • 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.

  • Pavilion Notebook PC 15-079er: problems with sleep and shutdown 15-n079er HP Pavilion Notebook PC.

    Hello world

    I have a huge problem with my Pavilion. I used Windows 8.1 earlier, and I decided to upgrade to Windows 10. I did not like something (can't remember what) and decided to return to Windows 8.1. Almost a year passed, I am again on Windows 10. But if I SLEEP my computer:

    • Screen goes black, everything seems normal.
    • No matter how long wait, fan keeps spinning and power LED, LED Wi - Fi on.
    • Keyboard input does not help. Does not meet what it is.
    • The only thing left to do - stop hard.

    And if I shut down the operating system:

    • Windows normally stops, close all applications, screen goes black.
    • Fan on, led on.

    I did not notice these problems with restarting and the hibernation.

    Two things I've done in this gap of the year:

    • Replacement screen. An old broke. Thanks to my cat...
    • Formatted the drive. I don't think it would do anything diffirent.

    So, any help would be appreciated.

    Thanks in advance,

    Hello

    On some machines, the pilot for 11 series IMEI has been known to cause that kind of question of the judgment, so it may be worth trying an earlier version.

    You can use the following method to install an earlier version of the driver IMEI.

    Download driver IMEI on the link below and save it in your downloads folder.

    http://ftp.HP.com/pub/SoftPaq/sp66001-66500/sp66228.exe

    Disable your wireless card (should be f12 ).

    Open your download folder and run the installer - it warns you that it is an earlier version, but simply continue.

    When finished, restart the laptop.

    If the computer shuts down correctly, turn on your wireless adapter and use the utility on the following link to prevent Windows 10 to update automatically the driver IMEI again.
