MY DELL INSPIRON 15 3521 BRIGHTNESS CONTROL QUESTION

When I bought my DELL 3521 a few weeks ago, that came with OS Ubuntu, I remember the brightness of the screen is adjustable using the Fn keys (F4 / F5).

Since I installed Win7 a few days back the brightness of the screen remain very dull (maybe the lowest setting), that doesn't bother me for my day to day work. But for my photo and graphic work, this intensity is far from satisfactory.

I have checked the internet on it and seen a lot of you also share the same experience. I did almost all of the advice given in it and since there was no improvement, I downloaded all the drivers on the official DELL site for Win7 and install.  Then something happened, it's now, I could see the brightness and the volume of the control on-screen icons or symbols.  Incindentally control of its (speaker) works very well (Fn/F10/F11/F12), while the screen brightness indication appears without any response to the keys (in fact, it indicates the maximum brightness in the scale, and when I try to reduce the scale reduced by point/scale and rest and not move any further).  However, there is no change in the brightness of the screen, which as I have already said, is low.

I have not yet decided to contact the dealer on this issue which might be a small question perhaps, that I am lying to reconcile with yet.

I don't know how to solve this problem. Is this a technical problem or a manufacturing defect? Could someone help me please. Must be very grateful.

Hi Gehan Wijesinghe,

Please go to the screen of the BIOS by pressing F2 permanently at the start to the top and do ensure that the behavior of the FN key is defined on multimedia. (See the image below)

  • What laptop to buy dell inspiron 15 3521 or 15 3542?

    Hello! I am a student and I am planning to buy a new laptop for my regular use.

    I'm confused to choose between Dell inspiron 15 3521 and Dell inspiron 3542.

    I know that inspiron 3521 is an and 3542 old product is a new version, but I am impressed by the performance of the battery and the reliability of the inspiron 3521. But I'm skeptical if 3521 will have the warranty and support both as the same as 3542?

    and I found a very few differences between the processors, they have either 3rd gen i3-227u and 4th gen i3-4005u. And windows 8 can be upgraded to 8.1 for free.

    the main reason I am leaning towards 3521 is design and reliability and there 65WH battery were as 3542 is well-bulky and 40Wh battery.

    Please offer me to choose between these two laptops. And I would like to know if the warranty will be the same for both products?

    Hi harrish.1992a,

    It seems that the 3521 is always available on the website of Dell India. The warranty is indicated under the pc as to how much time it is available. The two models seem to offer the same guarantee. You can always call and ask questions about the extended warranty.

  • Dell Inspiron 15 (3521) Touch screen replacement help

    This past Christmas, I got a Dell Inspiron 15 3521 touchscreen. Recently, I took it to his laptop computer case to find that the screen was cracked. It was not a crack in the external display. If you run your fingers on the screen, it's smooth, but there are visible cracks and a section of the screen that the office does not appear, but only an odd mesh of white and black with some other colors included in the section. I looked up the screen replacements and I found a detailed description on YouTube showing how to replace the display in the Dell Inspiron 15 3521. He was a link in the description of spare parts. That would solve my problem, but I just have a question: my phone is a touch screen and I am not sure if the replacement screen is a touch screen. I want to be able to use my laptop up. If it includes the ability to touch, I want a touch screen replacement. I'll post a link to the site with spare parts. Please respond and tell me whether or not it is tactile.

  • Problem with my Audio (DELL Inspiron 15 3521)

    Respected by all, I buy all new Dell Inspiron 15 3521 laptop 2 months ago. It was working great. A few days ago, the "Windows updates installed". and then I am facing problem in my Audio. When I start my laptop, within 5 minutes the sound stop working without giving me any message. When I disable Audio and activate again "Device Manager", he began to work, and then it works until the computer is turned off again. When I shut down my laptop and restart. the same problem occurs. I re - install Audio driver, but the problem persists. Please help me in this regard.

    Thank you

    There was a recent update of Windows that causes havoc widespread with audio. I suggest you try the solutions for this first before trying other things. Here are the 2 solutions the members of the forum have reported so far.

    ===========================================================================

    1ST SOLUTION POSSIBLE
    Countiss Forum member wrote that it is because of Microsoft...

    "KB2962407 update, stipulating that she fixed"Shortcut autonomy when an inactive audio device is not turned off on a computer running Windows". ".
    You don't have to do a restore of the system to get rid of updates; easier to go to Windows Update, view update history. On the top of this screen, click installed updates. "Then comes the with button the update you want to uninstall."

    =============================================================================

    2ND SOLUTION POSSIBLE
    Natakuc4 forum Member says update to Windows 8.1 will fix it. He wrote:

    "Ii you still on Windows 8.0." You should switch from 8.0 to 8.1 Windows Windows. See the instructions here:
    http://dellwindowsreinstallationguide.com/download-Microsoft-Windows-and-Office/Download-Microsoft-Windows/upgrading-to-Windows-8-1-from-Windows-8-0-via-the-Microsoft-store/
    Uninstall the audio and video drivers before the update. After the update, uninstall the network drivers and chipset and get drivers Windows 8.1 (WB64A).. »

    You can get the drivers that he mentions, either from the support page for your model once you select 8.1 as the operating system in the area of selection, or you can get the Dell ftp server, where they are named 'WB64A' and 'WB32A', which means 8.1 64 bit and 32 bit.

Here is a picture of headphones. Notice that the plug 4 segments instead of the normal 3 segments. It combines the headphones and microphone in a single dose.

  • Dell Inspiron 15 3521 graphics card

    I just bought a Dell Inspiron 15 3521, that contains the following components:

    -CPU: i3-3227U @ 1.90 GHz + Intel HD Graphics 4000

    -RAM: 4 GB @ 1600 frequency

    - AMD Radeon HD M 8730.

    The laptop came with Ubuntu 12 and I formatted everything; After that, I installed Ultimate SP1 Windows 7 x 64.

    Because I got no CD / DVD with its pilots, I downloaded them via the Dell Support site (choose my specific category) and with a pilot program; First, I installed Intel HD Graphics 4000 and then I restart the laptop. She has worked, good graphics. The latest driver I installed, dell support ( http://www.dell.com/support/troubleshooting/us/en/19/Product/inspiron-15-3521 - I chose Windows 7 x 64), AMD Radeon HD M 8730 that contains this description:

    This package provides the AMD Radeon HD M 8730 graphics driver and is supported on Inspiron 3 x 21 and 5 x 21 and Vostro 2521 running the following Windows operating systems: Windows 7 and Windows 8.
     
    After I reboot the laptop, when the office was released, the Office had a problem: (flashed) blinked quickly; I tried thousands of possibilities (uninstall it, download it again, uninstall Intel HD Graphics 4000 and first install AMD Radeon HD M 8730 and after that, reinstall the Intel graphics card; I tried a different version of the AMD Radeon graphics driver and no way).
     
    What should I do?

    In fact, the problem came from Intel HD Graphics 4000; If I install the latest driver for this material, part, it won't work (I'm still having this problem with the display flashing); But if I install a version more old Intel HD Graphics 4000 and after that I install AMD Radeon 8730 M driver, it works... Why is this?

  • Linux Mint on Dell Inspiron 13 3521?

    Hi all!

    I bought 3521 Dell Inspiron notebook with Intel Pentium Dual Core 2127U with HD VGA, Ivy Bridge, Intel HM76 Express, 4 GB of RAM DDR3, 500 GB of HDD, Intel® HD graphics last week.

    It was pre-installed Ubuntu 12.04 oem on it and works perfectly. However, as the person who will use it has used to Win XP and Win 7 I think installing Linux Mint would be a better choice for her and I did. Unfortunately, LM 13 does not work by itself, I have graphics problems causing problem and make non-functional system and it of course because it lacks drivers included in the oem version of Ubuntu. I restored back oem Ubuntu but I wonder if there is a chance that I can get LM works on this laptop or I'm stuck with Ubuntu for good? Is it perhaps an oem version of LM for this laptop available or could we somehow build it using the drivers included on the Ubuntu Dell restore disc and exactly how can you remove it?

    13 LM is equivalent to Ubuntu, but you will probably need to update the stack of materiel support yourself.

    More information here: https://wiki.ubuntu.com/Kernel/LTSEnablementStack

    The version of Ubuntu, delivered with your laptop is probably already set up with the battery on the right. Otherwise, there is no reason why Mint would not work while Ubuntu would.

    Another option is to use the latest version of Linux Mint (with cinnamon 2.0 which is a huge improvement).

  • Dell inspiron 7559 screen brightness flicker

    Hi, I recently bought a Dell Inspiron 7559 for school, my first laptop ever. It took me about 6 months to finally decide on a laptop, and I am very happy with it... it's beautiful. But I had two problems with the display. First of all, there is a slight yellow discoloration on half right, not a big problem, just my OCD, probably just a backlight bleed or something. But the big problem is that the brightness of the screen flashes constantly. I can only really noticed on the lowest brightness, but I use those so it's a problem. I've tried EVERYTHING. Tons of pilot fiddling, fiddling power supply option. I can't say if it sparkles in the bist of screen or the lcd screen of the bios, but I have disabled the NVidia intel HD graphics drivers and and no matter what I do, it still flashes. This makes me think that it is a hardware problem. If someone has an idea, I would really appreciate it. Do I have to send in for repair, or simply wait a little I read online somewhere that the lcd backlighting should "settle" so he can stop the blinking with takes a decent amount of screen time. Sorry for the long post, but this is my first pc, and I'm a bit picky about the function of my things. Thank you.

    How long have you had your xps and don't know if it's a hardware failure?

  • No microphone on Dell Inspiron 15 3521

    Hey, I have the Inspiron 15 3521 with windows 8.1 and it does not recognize the internal mic.

    For example when I go to the "speech recognition" and press "Set Up Microphone" I get 3 Options "Micro helmet", 'Desktop Microphone' and 'Other' rather than their work.

    I tried to reinstall the drivers and updating the system but nothing works.

    Help, please.

    Hi.I recently came across this problem. In my case, there was a small piece of rubber protecting the mic only slightly slipped and was covering the microphone. Just lift the cover from the top of the screen and remove the rubber or paste it again into the correct position. It is located to the left of the webcam.

  • problems with dell inspiron 15 3521: bios, graphics driver, drive Max

    OK first let me start off with audio I bought this laptop earlier this month and I noticed after a week tht one of the speakers has not been done no sound so I looked and most of the people, said her probably a driver or a balance so I checked all kinds of sounds tested left balance speaker mute or not mute (only the left speaker works) I uninstalled the drivers (realtek) tried it out with the Trusted (sarcasm) windows 8 drivers only its tht came was left aside I also checked with him the dell windows Diagnostics both before windows he showed tht, everything was perfect and diagnostics bios dell had a sound check, so I tried it and only had sound in the left (so im guessing this is not not a windows problem). So if I miss sumthing here pls enlighten me as I have not installed sound mods vlc or wutever so I don't skip infact I don't think I've ever done my volume sound goto 100.

    Second problem is the bloody grahics driver first time I opened my laptop, he told me to check my graphics driver and started acting out (my screen was blurry) so I tried to install the latest driver that didn't help so I returned the laptop and got a new... same problem after I found theres a specific driver that he recommended that works. Now if any of you are assuming that oh so what just cuz the graphics driver is not up to this day he should at least perform normally not act as sumthings broken or overheated... .well not it not anyho is the problem always sumtimes asks me to check my catalyst (he does not do anything when I click it) but that's all it works fine another tht can and I'm not sure if this is related to the graphics or disc bt sumtimes it turns off automatically and selects on some im do (especially on firefox) also tht problem was on my first computer laptop bt it was very common
    This brings us the third disk problem... the system is great other then all of these problem bt sumtimes I noticed it starts hanging in the boot and the reason behind it is I noticed that on my task manager, the disk will 100% use mainly cuz of system and antivirus loaded thereon im bt guessin' meadow is a windows problem 8 I don't really know

    OH and I almost forgot the Yes of the bios when I had my second laptop as the third day, there was a mistake that I woke up that I had left my laptop on all night on a normal surface meaning, there is no heat or anything like that... it wasn't hot anyho has committed a random error sum which I restarted my pc came to the dell screen and then a black screen that he said media controls and then FAIL
    then he said control media FAIL and it starts normally and it does every day since tht then of course diagnostics and everything works fine, he said that everything is fine TELL me HOW to MAKE IT GO AWAY

    azk_1
    Yes, it was the front windows dell dignostics the f12 wen u GET u turn on the pc

    That might have been the PSA Diagnostics. Dell 32-bit audio Diagnostics play a piece of music, but the PSA tests just play system sounds. Anyway, you wrote "and the bios dell diagnostics had a sound check, then I tried and didn't sound in the left. If you did not hear audio in right during the diagnostics speaker then the speaker needs to be replaced.

    azk_1
    BT he nevr said that he self tht the speakers have a problem, he said everything was fine

    No matter what the tests said - it is important only if you can hear the sound of the set of tests. If you can't hear it there is a hardware problem.

    azk_1
    and what abt the error its also before starting windows... .black screen then it says media controls and then fail whats tht abt

  • Dell Inspiron 1520 screen brightness adjustment does not

    When I try to adjust the brightness of the screen by pressing the Fn key and pressing the up/down arrows, nothing happens. I finally found it to work several months ago. I downloaded Dell Quickset and BIOS update today, but this does not solve the problem. Any constructive suggestion appreciated.

    Brian

    I just tried this and IT WORKED! I don't know how much luck you'll have, but try the Fn key and pressing the up and down arrows while your computer starts. It worked for me. For my Inspiron 1420, I adjusted the brightness, while he was when the screen went black and the words "Microsoft Corporation" above and the Green loading bar going across the screen. That's what I did and I hope it works for you! :)
