Keyboard Dell Inspiron 7537 after reboot (or start-up) does not work

Hello!

I have a Dell Inspiron 7537. New installation of Windows 8.1. All drivers and updates for the installed BIOS Dell form site.

After I restart (or turn on) my laptop, sometimes keyboard does not work. Only the special buttons as light keyboard or airplane mode to work. All others - letters, numbers, etc. of the win-key will not work.

Question is completely random and not possible to recreate on purpose. Maybe a week without this problem, or can happen tomorrow.

What I tried:

1 reinstall Windows

2 removing and reinstalling Microsoft form of default keyboard driver in Device Manager.

3 update BIOS

4. run integrated Dell diagnostic utility (spent)

5 disable quick start setting and allow him to return.

I have a strong feeling that it's a software problem.

At the moment the problem is still there. Can someone give me some advice please?

After the upgrade to Win10 - didn't notice any problem. Thread can be closed.

  • Dell Inspiron 3147 11.6 "- touchscreen"in part"does not work after the pilot light"

    Every time when the laptop goes to sleep mode in itself and I put on, the touch screen will be in part does not, to be more precise, is the upper part of the screen. The problem is that on the screen, mouse and touchpad work correctly. Now I can solve the problem by pressing the power button to let him sleep and a second time to activate it, but I don't want to do it every day.

    Anyone has the answer to this? Please, I beg you! I just got a few days ago!

    Thank you.

    Hey, guys, I had the touchscreen partially responsible (upper right part) + 100% of the CPU. What I ended up doing, it was a clean install of Windows 10 and do NOT install Dell Quickset. I repeat, DO NOT install of Quickset. Hardware works fine without it and I stopped to get 100% of the CPU after idle and touch screen works normally. The only downside is that I get an unrecognized component (ACPI\SMO8810\1), which I think has to do with the keyboard locking in tablet mode. This isn't the complete solution of 100%, but I feel that the Dell power plan is not coded correctly. For any question, you guys might have, let me know!

    Do not have access to Safe Mode if you ignore the system restore and click on the button on the Start Menu?  Your initial problems are repeated in this case?

    If you can access Safe Mode things, see if it will help you create another user, and it will allow to test this new user in Normal Mode of loading.

    Also, if you can in Mode safe, download and run this program in mode safe mode and let it scan your computer for malware.

    Try this mode safe too.  Try running ChkDsk to check your drive for errors. Right click on your drive icon / properties / tools / error checking.  Try first by checking do not each box (that it will run in read-only mode) to see if it reports any problems file or hard drive.  If so, restart it by checking both boxes and restart to allow him to attempt to fix any problems found.

    If Safe Mode is not an option for you, see if you can access options of startup repair (be it to start any Windows Vista DVD or the Safe Mode screen options).

  • February 25, 2015, after agreeing the Firefox Hello does not work dwhelper. All proposed tests without success.

    I was download Firefox Hello a couple of days. dwhelper no longer works. I tested the extensions. As I only have two, dwhelper and add-on, it was easy to do.

    I use a lot dwhelper. I use online videos from many sources for my physics and astronomy, teaching needs.

    It is a problem with many video sites, not just YouTube.

    I deleted dwhelper and reinstalled. Firefox started and stopped. Rebooted my macbook pro as well.

    Program seems to be working and including window specifying the location to place the download file.

    Hello from Firefox is not a separate download - its share of Firefox itself. There is no direct interaction between your navigation and the morning of Firefox.

    It is more likely that Firefox updated to the latest version, and something in the change means that dwhelper does not work as well. I suggest you ask on the support site of the developer of the extension http://www.downloadhelper.net/documentation.php

    According to support threads this thread, there is also a beta version available that could solve your problem.

    Unfortunately its hard for us using extensions, they are developed by third parties.

  • Equium - dead after hibernation, the system recovery does not work

    Hello
    I'm trying to fix the laptop of one of my friends, but so far without success. It's a Toshiba Satellite with Vista.

    She had problems with a black screen after startup in Windows Vista. I found a work around for this problem, but it was a little complicated for her... She doesn't know much about computers. ;)
    So I but it would be a good idea to tell him to always use hibernation. However, when I put the portable standby extended, all seemed fine, shutdown, power off.
    I tried and then turn it back on. Light turns green, cd drive makes noises. Nothing more. Screen remains completely black. No sounds. Keyboard input does not work. No access to the Manager startup or anything else. He left light until I pass him by pressing the button for a few seconds.
    I removed the battery and put back in place, without result.
    Connection to an external monitor shows no results.
    When I put the original CD recovery Toshiba, no results.

    So, basically a cell phone dead. Ah yes, I'm in the Brazil in a small village, away from the stores of tech support or computer. Maybe a problem material, but all was working fine until I used the hibernation.

    Any help or ideas would be very appreciated! ;)
    Daniel

    Hello

    My laptop could not wake up after hibernation too but I managed to wake up again.
    This;
    Disconnect the power adapter and remove the battery.
    Now, you will have to wait a while 1 hour should be sufficient, but you can leave the laptop disconnected for a longer time (all night long)

    After that, you must connect the battery and AC adapter and should try to light the device if it will not help you then you are in trouble
    This would mean that a serious hardware problem causing this problem and I doubt you could remedy without any help from the ASP.

  • Satellite A200 - 19L: no sound after hibernation & CD/DVD drive does not work

    First of all, my laptop computer became very slow loading vista after formula 1 week to buy it.

    Second, sometimes when I put the mode 'sleep' a revival of the laptop, there is no sound and a red circle appears over the speaker icon in the bar of tasks, and when I go into control panel > Sound, he tells me that no. his drive was installed and when restarting the laptop the problem resolved?

    Thirdly, after the formula of the week 3 buy the computer also dvd - cd player has the same problem, like the sound and when you open my computer that NO cd\dvd drive icon and when I put a cd or dvd, it does not work or run and it happens all the time, even if the laptop restarts.

    Since then im able to watch movies or work.

    I'm lost and I don't know what to do!
    (Sorry for my bad English, but I hope you understand the problems)

    Hey Osama

    I think I can help you. The questions that appear on your laptop are not serious and the only one associated with software or registry.

    Regarding your noise problem:
    Please check this Microsoft document
    http://support.Microsoft.com/kb/929685/en-us
    or
    http://support.Microsoft.com/kb/937077/

    the MS update must be downloaded and installed ;)

    Regarding the missing CD/DVD drive;
    I think you should try to remove the drive from Device Manager and reboot the laptop. Then the operating system should recognize the STRANGE again.
    Secondly you should access the registry editor and should remove the upper filter and bring back the key filter
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Class\ {4D36E965-E325-11CE-BFC1-08002BE10318}

  • Windows 8 - not able to access 'Change PC settings'; Unable to create a user profile. Store/Start menu does not work.

    Hello

    Recently, I'm stuck with these issues:

    1. not able to access 'Change PC settings' - when I click on it nothing happens.

    2 start menu/Store does not work - I am using the profile of the user admin Start Menu is a blank blue screen with just the user name appears at the top right. Store is completely scratched too.

    While the guest user has all the tiles in Start menu/store.

    3. cannot create a user profile - I wanted to try to create a new user profile and check if the store is working properly. When I click on 'Add a new user in the laptop settings' nothing happens.

    I tried the system restore, but it does not solve all of the above. Is there any solution to these problems without having to reinstall Win 8? I don't have the installation discs.

    TIA!

    You can use the restore or refresh options without going in the settings of the PC.  Read the instructions carefully, it says:

    If you can't identify, or use laptop settings app, you can access these rather safe mode options. On the login screen, click on the power icon, and then hold down the SHIFT key on the keyboard while you click on restart. Now keep update until the next screen appears.

  • After that insert update trigger does not work properly

    Hello experts!

    I created an insert/update trigger after and what strikes me is that it does not work as expected.
    The trigger starts a procedure that performs an insert in a second case of changing values table triggered table ("my_table").

    The problem is that in my second table values, which are correlated to the "my_table", are not changed by the correct values immediately. The trails of the trigger and insert!

    I need to update two times to values appear in my second table. Then only the data of the first update will be inserted in the second recital to table the table parent ("my_table") held the most recent values.

    Do you have an idea what could be the problem?
    create or replace
    trigger myscheme.after_update_insert_set_tw
     after update or insert
      on myscheme.my_table
      for each row
      
    declare 
    
    begin
    
     pr_my_table_tw_sync_sk(:new.lng_falle, :new.int_fallennummer, :new.lng_schaedling, :new.objectid);
    
    
    end;
    Brgds,

    SEB

    Remove the pragma autonomous_transaction and validation of your relaxation. This might be the reason. The transaction autonoumous cant properly consider the values of the current transaction (which is not engaged yet).

    This is not logically (if the upgrade fails or is rolled at the time you do not want the inserted row).

    If you then get a problem because the mutation of tables, you will need a different solution: an autonoumous transaction is not the right solution to workaround.

  • Satellite L670 - after Win 8 upgrade WIFI does not work properly

    Afteer upgrade to Win 8, the WiFi of my Satellite L670-128 has stopped working properly.

    The connection only works some time, usually only a few seconds before the connection is lost.
    After a few seconds or minutes the connection is restored, just soon to be lost again.

    Cannot download large files or even to see larger photos on normal web pages. Is there any Win8 driver for Broadcom coming 802.11n network card, or should I throw one 2.5 year old computer in the trash?

    Buy a usb-wlan card is not an option, as wireless mice is already "permanently" reserving one of the three usb ports and wlan card it would be just to the left...

    To my knowledge this L670 series isn t Win 8 taken in charge and this means that there is no special Win 8 drivers for this device, so I put t think you will find an another Win 8 driver for this WLan card.

    But do you really want to throw this laptop in the trash just because the wifi does not work properly running Win 8?
    The device was working properly under Win 7?

    I would recommend running a few Wlan test.
    For example; Disable wireless encryption on your router and Wifi connectivity with the open network do that just for testing purposes, perhaps you will need to change the type of encryption to test.
