Dell Inspiron brightness (FN + F4/FN F5) keys not working only not on the operating system Windows 7 (64-bit)

Hello.

I bought a Dell Inspiron N5110 for my son who has vision problems. The laptop has been brilliant, but now he is suddenly unable to use the keys FN + F4/F5 to turn down the brightness. The F4 main movements only 1 level of maximum brightness and it has meant he is unable to use the laptop because it's too bright. I tried to re install different drivers from the Dell Web site without success.

I hope someone can help out us here as the laptop is crucial for the education of my son, especially given his eyesight problems.

Thanks in advance to anyone who can help me.

Hello.

I just managed to solve the problem. I uninstalled Teamviewer and the FN keys began to work properly.

I then installed the latest version of Teamviewer and the keys still work very well.

Thank you very much for all your help resoling this issue.

    Check maual of the user of the ignition key (e.g. F11) you need to press on when you first ask the computer to access the XP restore partition. If you have a "restore CD" the game that the BIOS so that the CD-ROM drive is the 1st device to start, followed by the hard drive. then power on the computer and "press any key" when prompted to start the installation.

  • Some pavilion dv7 keyboard keys do not work. Operating system Windows 7 4 bits

    I hope someone can help me before I have to call HP.

    My laptop is just a little over a year. Worked very well. Suddenly, without factor precipitating known, press the caps lock light has stopped working. Not a big deal, but I do not know if the caps are locked or not. Interestingly, the same key suddenly started working after a few weeks of a malfunction. Then it stopped working again on its own. However, then the 'six' key stopped working completely. Went to the Forums and the less discovered how to appear and use the screen keyboard, but it's a pain.

    Now, the keyboard has worsened and there are five keys that don't work at all.  Obviously, five keys is one of them.

    I had seen the forum and read suggestiion to remove the battery and the push button for a time, did this, but nothing helps. There was another similar suggestion that doesn't work anymore.

    I would like to solve the problem before the warranty runs out. Suggestions? I appreciate all the comments. TX.

    This problem occurs in all programs? Honestly, this looks like a problem with the hardware keyboard. If you are still in warranty, you must take this opportunity to speak directly with HP support.

    You can check the status of your warranty here.

    If you are in the USA / Canada, just give them a call at 1-800-474-6836. If you are in another part of the world, you visit HP's Support around the world to find the coordinates for your region.

    Have a great day!

  • Dell Inspiron 531 s problem of power/does not recognize the hard drive

    My Office does not illuminate. I replaced the power supply. No, it powers on but does not recognize the hard drive. It gives an error as SATA 0 None SATA 1 no SATA 2 No. How do we know that the cables are properly connected. I feel like I'm very close to solving the problem but don't have a clue what that next step to follow

    The original PSU had 4 sets of cables and connectors.  The new power supply has 5 sets of son.

    From your post, I guess that the configuration of the system now recognizes the hard drive?

    If you do not have a floppy drive, then BIOS can find the player who isn't there, it returns this error.

    Make sure that the floppy drive [drive A] is disabled in the [BIOS] installation system, page 173, so that it is no longer looking for the disc and see if this stops the error message.

    If the hard drive is recognized in the configuration of the system, he now knows in windows "My computer" or in "disk management, [right click on 'My computer' and select 'Manage', then disk management]."

  • No satellite L855-B511 - how to activate the operating system Windows - no serial key

    Hello

    I had to replace the HDD on my L855-B511, I tried to create a recovery media to replace the HARD drive by using both DVD and USB sticks, but it didn't work because I think that the HARD disk has been corrupted.

    There is no license sticker windows at the rear of the laptop or under the battery (only the windows logo 8), so I downloaded an app to retrieve the product key from the registry, but after reinstalling windows, I tried to turn it on, I discovered that the product key is not valid (tried the application on another machine and it gave me a product key different than that on the sticker).

    is there a way I can reactivate windows without having to purchase a new license?

    > is it possible I can reactivate windows without having to purchase a new license?

    There is unfortunately no way to do it. In my opinion, your problem is clearly guaranteed service provider and the question should swap HARD drive for free. This model is fairly new, so I assume that the warranty is still valid. You could tell the guys to service this recovery media creation didn't work and ask if you can get a free recovery media.

    If you want to fix on your path you must order the new recovery disc. This laptop model is available on the Middle East so I don't know if you can order it on https://backupmedia.toshiba.eu/landing.aspx but you can check it out.

    I have an original cd of Windows XP Home Edition with the product key for it and want to use it... but when I look at the disk, according to me, he said: "Don't use this CD to reinstall the operating system on Dell count" that I had in 2004 and have more... what I want to know I can install it on a different computer now and it would be legal?

  • A key, but not cd/dvd for the operating system

    I received my new computer, but did not come with the operating system installed. It has the key for windows vista, but not CD... How to install the operating system

    Read the info below:

    How to get Vista recovery Media or the Vista recovery Partition on your computer back to factory settings.

    There is no Vista free download legal available.

    Contact your computer manufacturer and ask them to send a recovery disk/s Vista set.

    Normally, they do this for a cost of $ small.

    In addition, ask them if you have a recovery Partition on your computer/laptop to restore it to factory settings.

    See if a manual provided with the computer or go to the manufacturer's website, email or you can call for information on how to make a recovery.

    Normally, you have to press F10 or F11 at startup to start the recovery process...

    Another way I've seen on some models is press F8 and go to a list of startup options, and launch a recovery of standards of plant with it, by selecting the repair option.

    Ask them if you can also make recovery disk/s for the recovery Partition in case of a system Crash or hard drive failure.

    They will tell you how to do this.

    Every computer manufacturer has their own way of making recovery disk/s.

    Or borrow a good Microsoft Vista DVD (not Dell, HP, etc).
    A good Vista DVD contains all versions of Vista.
    The product key determines which version of Vista is installed.

    There are 2 disks of Vista: one for 32-bit operating system, and one for 64-bit operating system.

    If install a cleaning is required with a good DVD of Vista (not HP, Dell recovery disks):

    Go to your Bios/Setup, or the Boot Menu at startup and change the Boot order to make the DVD/CD drive 1st in the boot order, then reboot with the disk in the drive.

    At the startup/power on you should see at the bottom of the screen either F2 or DELETE, go to Setup/Bios or F12 for the Boot Menu

  • If I put all my files on the C drive that has the operating system and make a recovery of keys one, will I lose my files?

    If I put all my files on the C drive that has the operating system and make a recovery of keys one, will I lose my files? drive C whereas the partition that has the operating system and drive D is the lenovo drive that has all the drivers lenovo and all those. Did I lose my files?

    Yes, the collection clears all of the C drive and you will lose your files. The solution would be to backup regularly to an external HARD drive and after the key one to also restore the files from the external hard drive.

    This has been answered before, if you do a search for "key recovery" it appears among the first results.

    Reinstalling windows 7 after re-start of windows xp

    I bought my Asus computer came with windows 7 installed, earlier this year, I encountered a problem with the blue screen to come and I was unable to fix it, when I had my computer repaired they changed the operating system to windows xp, I was wondering if with registration # or whatever is on the side if I could download and reinstall Windows 7

    If the product key on the side of your machine is for Windows 7 and where-ever you guessed it "repaired" installed Windows XP - the real question becomes where they got a product key for Windows XP?

    You have the installation media for the copy of Windows 7 OEM which is preinstalled on your computer?

    If not - you will probably need to contact Asus (this laptop?) over media restore and/or check to see if the "repair" left any which restoration method should have been used intact.
