The display is darker that usual (aspire 3820 t)

Today, when I turned on my Acer Aspire 3820 t the screen was much darker than usual. Everything looks very good and is visible, but only looks like I put the brightness to the lowest setting. I tried to change the brightness, but it looks the same, no matter what I put it.

I use an external display and more integrated into the computer notebook monitor and the external monitor works fine.

OS: Ubuntu 14.04

  • Brightness of the display on Satellite Pro 4300 very dark

    Hello
    I have an old Satellite 4300 Pro that I've updated for my daughter last summer.
    I spent some time just right, put the upgrade of memory maximum and the installation of Windows 2000.

    She just gave it me as she has a new model... and I need the laptop.
    In any case, although it starts, the screen is very dark... totally unusable.
    Oddly, the display is dark during the part of the BIOS of the start-up routine as well.

    I tried many combinations of keys F nothing helps.
    Any suggestions?
    Phil

    Hello Phil

    Pleae note that use of the combination of keys for brightness settings work, just at the moment where OS is started and if some Toshiba designed tools are pre-installed. If this happens when starting laptop too and the BIOS settings are not visible properly I assume the inverter FL (backlight) is defective and must be replaced.

  • Portege R700 - the display hinges are loose

    Hello

    my brand new R700 seems to have a bit of a monkey of surrender of a screen on this subject.
    When I use the machine at home, I'm sitting on a coffee table, titration so the screen in an equitable way back at right angles to the display

    If I then get the laptop to use it on mine... well, basically... the screen returns to fully open/flat right through the movement of lifting machine

    Someone else had a similar problem and if yes is it too simple that chew up the hinge bolts and how they access do?
    I rip portable outside all the time, but never a new brand that I'm worried about scratching, so I want to assure you that I understand!

    see you soon

    Ben

    Hello

    Don t have had similar problems with my laptop but maybe the display hinges are loose
    Usually, these hinges are hidden behind plastic chassis and you would need to disassemble the laptop to get access to these parts.

    In general I put t recommend disassemble this laptop pretty.
    First of all, you will lose the status of the guarantee if you would remove the plastic cover.
    Secondly, you may damage or break this, and I think that that's not worth a risk.

    If I was you, I'd spend low and ask a technician for assistance.

  • PSE9 seems to cause a change in the display on the video card ATI Radeon Mobility in Win7

    Recently, I had some problems with my Dell StudioXPS 4650 and had to return the computer to its factory delivery configuration.  Then I reinstalled all my programs to it.  This whole process took a couple of weeks.  Things re-installed a Creative Suite Production Pro (CS 5.5).  The all last program I have re-installed, a few days before, was PhotoShop Elements 9.  Almost immediately after I started having display problems!  As mentioned in the title of the question, I have a videocard ATI Mobility Radeon HD 4670 with 1 GB of RAM video.  I have a processor Intel i5 with 6 GB of RAM.  Oh Yes... Win 7 Pro x 64.

    Anyway... any time the graphics loading gets "heavy" (busy), such as open several Web pages, view a video in Media Player, etc, the screen fills with noise, random groups of pixels, and do one of two things-clear up and give me the message that the video driver failed and resets or go to a BSOD!

    As I say, it started once I have re-installed PSE9 and I had a similar problem (usually restricted this year to the actual graphics programs such as PS 5.5) after the installation of PSE9 the first time, so I feel that PES should be somehow at fault!

    I don't mean to blame someone or something like that, I'm just curious if anyone else has had a similar problem and, if so, how they resolved/fixed!  All this, of course, is based on the question, "PSE9 does anything in Control Panel during installation, which could explain this?

    Any help would be GREATLY appreciated!

    Thanks in advance!

    I don't think that items is the cause, it is usually the display card drivers that cause this.

    Make sure you update your display driver on the ATI site not through windows update.

  • I did the screen too small (using about: config) and lost the address bar and all the menus. How to restore the display on a screen size can be used?

    I changed the size of display screen using about: config, as stated in the other answers help. After you use a value of 1.0, such as recommended, I've experimented with other sizes, because it seems small. I have entered a large number by chance (a typing error) and made the display so small that only a bug could read. And I lost all the features: bar address, menus, home, Favorites, settings icons.

    I uninstalled and reinstalled Firefox, thinking that this would fix it. But the new facility displays the same way: unreadable and no functionality.

    I found instructions on resetting to the factory settings, but cannot perform this task because I have to be able to access the menus to do so.

    Hello PaulaBob, have you changed the value of layout.css.devPixelsPerPx? -You can perform the following steps to change the still 'blind ': value

    1. Open firefox, and then press ctrl + L (this will focus in the address bar)
    2. type of topic: config
    3. Press ENTER twice
    4. type devpix
    5. Press the tab key
    6. Press enter
    7. type 1.0
    8. Press ENTER again and I hope you should be normal visibility now

    Hi Anthany,

    If you have a hardware device that does not properly with your computer, you probably need a driver updated. There are three ways to update a driver:

    • Use Windows Update. You will have to perhaps set Windows Update automatically download and install recommended updates.

    • Install the software from the manufacturer of the device. For example, if your device is equipped with a disk, this disk can contain software that installs a driver for the device.

    • Download and update the driver yourself. Use this method to install a driver that you download from the manufacturer's website. If Windows Update can't find a driver for your device and the device didn't come with software that installs a driver.

    Step 1: Download and install the latest version of DirectX.

    Step 2: Download and install the latest graphics driver and see if it works.

  • My hp dv6-6195 ca changes the display brightness when you look dark or black backgrounds

    My laptop has started to get a question where I come back to a page with a black or dark background and it seems as if my brightness has dropped. If I transition to a page of white or clear, it slowly goes back to the original brightness. Is there any software issues I can change in the related settings or would it be a hardware problem? My laptop is out of warranty, so I don't know if I can send it to get her replaced screen if it's a difficult problem. Anyone else having problems with the display of brightness varies when going from dark to light?

    The last action I can remember was the upgrade of the AMD Catalyst Center, but I have found no setting he woud change that.

    specs: WIndows 8 | HP Pavilion dv6-6195 ca | I7-2630QM | 120 GB OCZ Vertex 3 SSD | 750 GB 7200 RPM hard drive. 8192MB RAM | Radeon HD 6770M 2 GB | FHD LED (1920 x 1080) anti-glare display

    It is because the intel hd graphics driver you have in your system... steps, I followed to resolve are -

    (1) right click on desktop, and then open the graphics properties

    2) click on the column on the left power tab

    Select battery 3) in respect of the power source

    (4) uncheck the display power saving technology

    (5) reboot your system

    90% of the time it should start without this question for you, 10% of the time, it can further lower your brightness even if you uncheckd the option but a reboot again simply would help

  • Crush the display flashes for 2-3 minutes after that mini mac wakes up from sleep

    Crush the display flashes for 2-3 minutes after that mini mac wakes up from sleep

    If you have another Thunderbolt cable, plug it into the unused port on the

    Thunderbolt Display and then in the Mini and see if the same thing happens.

    What you can see is a precursor of the poster, built out of the cable.

    At least, it could eliminate a costly repair problem.  Although the cable itself is not

    expensive, opening to the top of the screen of TB to replace could be.

    Well that not connected on a Mini, I began to see in similar behavior my

  • One of my computers works very well to display my beneficiaries of my bank online and the other computer says that I don't have any beneficiary, worm 35 on both.

    Everything on my online banking Web site works fine except the display of my beneficiaries. It does not, he tells me that I don't have any beneficiary. This function works very well on my backup computer with 16, 32, and 35 versions.

    That's what my Bank said:
    There was some problems with the compatibility of Firefox to view online recipients. Please, try the following steps to clear the cache and delete cookies. If there is still a problem, start Firefox in Mode safe. While you are in safe mode, press the < Alt > or < F10 > to display the toolbar. Then select Tools > Options > advanced > general. Find and stop using hardware acceleration.

    Boot in safe mode to fix the problem, but it's a bit of a pain. A refreshment or a reset seems a little drastic and I would like to know what exactly is the problem before using the shotgun approach.

    Thank you

    Thanks for the replies. I have try to disable hardware acceleration, but probably no connect fees. My only add-on is edge of adblock and I disabled it for the site. The thing is, I don't want to disable either of these elements. I'll just start firefox in safe mode, if I need to access my beneficiaries. I was hoping that someone may know something that is bad in my profile that has carried over from previous versions or another kind of corruption. It seems strange that an entire site could work very well with hardware acceleration, but not to this one point.

    Your machine is still under warranty, so you should take it to your local Apple store for repairs. Function late in January, you bought it, you still have phone without support. If you can't find any help on the Apple Store, then I don't know what you expect to find here. We have no way to check for problems you have described or any additional hardware, etc.
