lack of brightness control
When I upgrade from vista to windows 7 missing control brightness and when my laptop battery light don't overtemperature and brightness in power option is missing and I can not increase or decrease the brightness of function "fn" my laptop is sony vgn series.
How can I control the brightness?
Read the article: How to adjust the brightness and contrast of your monitor . You will find a section how adjust brightness automatically using Adaptive brightness.
You will also need to go to your laptop manufacturer website and search for a drivers. It may be necessary if you want to use the keys on your keyboard to increase/decrease brightness.
Depends on what graphics card you have, go to the manufacturer site and see is there any software for the control of your graphics card. This kind of software can automatically adjust the brightness when you unplug your laptop. It could be ATI Catalyst Control Center... but it depends on what graphics card you have, you need to find the website of the manufacturer of graphics cards.

Portege M200 tablet - screen brightness controls F6/F7 does not

Thank you

Hello Laurence
From my experience, you need the Hotkey Utility for display devices. The new version is v2.6.0.000. You can find this tool on the Toshiba site.
Please take a look at this site:http://EU.computers.Toshiba-Europe.com

HP 14 laptop: brightness control problems
Hello
My mother has recently bought a new HP 14 laptop and when the AC is plugged in, the display BRIGHTNESS varies from no visible state. Brightness controls are also reversed, for example when I press the brightness control, it will be brighter.
I thought it could have been a graphics driver issue but I have updated graphics for the latest versions and still no change. graphic design is a "Intel HD 4000'.
All the solutions to this problem would be great,
Thank you

Hello and thanks for the display on the HP support forums. With Windows 10 some of the performance parameters are a bit off. The first thing I would try is running an update of the system BIOS. Or BIOS Reset would be my first choice.
Here is a link to help you with this.
Please let me know if it helps. Thanks again for posting and have a great day.

UGG knew the deivce is working good
I did a live update for a new bios it installed and work, after the reboot, my screen metor is slow, he hasmore icon than he had done previously and now my brightness control has stopped working on the screen. I can't turn down the brightness at all in the control parameter or power controls.
How to take the subway at only 3 rows of icons and how do Iget my brightness control works again? It's virtually unusable tablet, screen is bright andmetro screen is horrible slow. Already done a reboot, live update shows no new updates.
Need help on this a little.
Nevermind, I saw in the device manager that the firmaware somehow wantedanother restart to complete the update of the firmware. Very strange, because it seems to complete the first time and the live update did not show anything in the waiting.

Is IM having sony vaio e15117 possible to control the brightness of the computerWhen the brightness control menu does not work please give me a solution
Hello Shaik,
Thanks for posting your question on the Microsoft community.
Thank you for details on the issue.
This problem may occur because of corrupted display drivers or incorrect display or power settings.
I suggest you to perform troubleshooting of power utility and check.
Reference:
Open the troubleshooter of power
http://Windows.Microsoft.com/en-us/Windows7/open-the-power-TroubleshooterTroubleshooting of power check things as settings timeout of your computer, which determines how long the computer waits before turning off the display or enter the mode 'sleep'. These settings can help you save energy and extend the life of the battery in your computer.
Please also to update the website of the manufacturer of the computer display drivers and check.

Computer laptop HP G72-130ED - the screen brightness control never worked again
Hi people,
I've had this laptop again (in 2010) and control screen brightness function keys never worked.
All other functions working keys, it's just the f2 and f3 (light downwards and upwards) are not.
All updates (from the site of HP Netherlands) support have been installed.
In addition there is no brightness control of in control panel windows or which would allow control over the brightness using the mouse.
It would be great to have control of the brightness of the screen because the screen is really bright and it is unpleasant to use in any other circumstance during the day!
Grateful for your help, Zion.

Hi all
I use a MacBook Pro (13 "to end 2011) and iMac (27", by the end of 2012). Both are up to date, running El Capitan 10.11.5. They are connected with a thunderbolt cable in order to use the iMac as a second screen (TDM).
Now, when I press CMD + F2 to the iMac, iMac gets used as second screen as expected, but it goes really dark! He's not black, you can still see the desktop but on a sunny day, it's really hard to see anything. Now, it's pretty embarrassing, but the second part of the question makes it a pain in the *. When the iMac is dark, I always go to the system preferences and open the settings for the display. I can see a window with the parameters for the iMac, but there is no cursor for the brightness! There is no way to make it brighter!
The only solution is to disable the target (CMD + F2) just display mode to enable it again after a few seconds. Sometimes I have to activate the TDM twice but sometimes it takes 4 or 5 loops toggle just to see the brightness slider!
Here is a screenshot of the settings without the cursor window
And that's what it looks like after a few loops, and then I can adjust the brightness.
Any ideas why this happens? Any advice on a possible solution? Why - what is darkening the iMac? Why is the cursor missing?
Best,
Stephan

Satellite Pro R50 - brightness control F3 does not work
Hello
I have a R50 Pro Satellite - bought just 1 month ago.
Suddenly the order of function F3 to control light intensity has stopped working.
The brightness can down with F2 function but F3 does not work
F3 in the software and the operating system back to research, but do not work by pulling the brightness setting.
So I'm stuck with my brightness down as low as it goes.
I downloaded the latest driver for the feature key and installed, so it isn't that.
Anyone got any help they can give?
See you soon
CraigAs a temporary solution, you can change the brightness in the power settings.
I really don't understand what the problem may be, but try to reinstall the utility system then Toshiba and Toshiba driver to feature key. -
Qosmio F55 - LCD replaced and brightness controls are reversed back
Hello
the LCD for my Qosmio F55-Q502 cracked and I ordered the same room and when I installed it, everything works fine and everything but the brightness up and down are reversed. As Fn + F6 makes more brilliant while Fn + F7 makes it more dark? The first that comes with it is a lp154wp1 (tl) (e1) but I had is a lp154wp1 (tl) d1).
Does anyone think that the bit of a variation of the model can do reverse controls? Even on Windows when you cursor to the right BRIGHTNESS, it darkens and to the left, it illuminates. For anyone else who needs information on their Qosmio F55, the original is also a lp154wp1 (tl) (e1) and also known under the name of lp154wp1 (tl) (a3) which is written on the Board of the lcd screen. The replacement lp154wp1 (tl) (d1) is also known as a lp154wp1 (tl) (a2) also wrote on the lcd dashboard
Any suggestion or help would be appreciated!
Hi hulkster,.
Where you have ordered the new view and it are a Toshiba original spare part?
If yes I would contact an authorised service dealer or the store where you bought it. In my opinion the screen is not 100% compatible for your model. This would also explain the different reference numbers you posted
