Sony :: Hotkey Will Not Change Brightness

Dec 8, 2009

I did a clean install of Windows 7. I did not load all that crap from the 2nd CD.I am trying to determine which Drivers I need to install.

I installed the VAIOģ Event Service and Sonyģ Shared Library.

What is strange is, when I click on the FN button and press the increase brightness key, the brightness meter does appear on the screen, but it will not go above the lowest setting.

Acer :: Change Language For Hotkey/launchkeyExtensa 7620

Dec 3, 2007

When I press the wlan or the bluetooth key, the short message is in Finnish. I would like to have that in English or Swedish.

Is it possible to change? How?

The notebook is an Acer Extensa 7620. Tried to find a driver for launchkeys, but no driver is available on their ftp-site for this notebook. Can a similar driver work? And what name has that driver?

Sony :: Vaio FZ LCD Can't Change Brightness

Feb 19, 2010

I've done a search and couldn't find anything relevant.

My FZ of 28 months old has suddenly started making a faint buzzing noise from the screen.

At first I thought it was the fan, but I realized it's the LCD. I can't change the brightness for some reason using Windows 7 but it's on Max Bright. I've seen some threads of people having this problem on lowered brightness levels but this is happening on full.

When I shut the lid, the buzzing stops. It can be heard if I stand behind the laptop or place my ear beside either rear corner of the laptop.

Dell :: 1557 Brightness Can't Change

Dec 6, 2009

I got my Dell 1557 about a month ago and for a while, it seemed just fine with my display brightness.

I could change it to however bright I want it to be. Then today, when I turned on my computer, my settings for my display brightness was at the highest when it normally is in the middle.

At first I thought nothing of it because I could easily change it with the F4 and F5 buttons, but after I logged on and tried to change it, nothing happened. Not even after I restarted the computer or reinstall the ATI Catalyst Center.

Lenovo T540p T400 / T500 :: Can't Change Brightness

Dec 13, 2014

After updating my Thinkpad T540p, I cannot adjust the brightness in anyway. This is a problem because the screen is too birght and eats up battery.
It appears the only way to adjust the brightness is to use Intel HD Graphics, which isn't so convenient.
Fn keys don't work. changing the brightness on the Power Manager settings doesn't work. There is no brightness option on Windows Power Manager.
I have Intel HD Graphics 4600
I have Lenovo Power Manager 6.66.3
Edit: In fact, I think it's posisble that Power Manager to just outright no longer works.

Lenovo U/S Series :: Can't Change Screen Brightness Anymore - U410

Jun 27, 2014

For some reason I can't change my screen brightness anymore. I've already tried a HD 4000 driver rollback to version and I also disabled "adaptive screen brightness" at the power management. For some reason I can change the brightness by using the "microsoft basic display adapter" driver instead of the HD 4000 but that isn't a real solution.

Acer Aspire 5742G :: Unable To Change Screen Brightness?

Oct 9, 2014

I own a 3.5 years old Acer Aspire 5742G (Core i3 M380; NVIDIA540M). the heat sink or the collinig fan might have some issue as it usually gets overheated when playing games (even CS condition zero/1.6). I don't play games anymore, so its not a problem.
The problem is that I am unable to adjust the screen brightness from the keyboars shortcut (Fn+ Left/Right arrow key), neither from the control panel (Power Settings).

Although I do noticed something that, if I change my brightness settings (nothing happens) and I close the laptop lid (display screen) by folding it down and openeing it back after 3-4 seconds, the brightness is now changed.

Dell :: Inspiron 9300 No Brightness Control/white Screen At Bootup After Graphics Card Change

Jan 8, 2010

I have Inspiron 9300. Unfortunately, my geforce 6800 died and I bought as a replacement x300 which was installed by a laptop repair service (they fixed other thins too.

It was due to power surge). Everything works but when I boot up the computer or when the display is set to be turned off in the power settings in Windows instead of being actually turned off the display is on and is all white.

Also brightness regulation does not work via Fn +arrows keys and is set to maximum and the white color is so intense that I get a headache after a couple of hours staring at the screen.

Acer :: Empowering Technology Hotkey

Apr 25, 2009

how, when you press the "e" empowering technology button the toolbar pops up?

And when you switch on the bluetooth module, the WLAN switch, and even the FN+UpArrow and DownArrow and the little green text at the bottom of the screen comes up? Well, in my system it's not working anymore.

Last thing I remembered that happened was my Norton IS 2009 detected a virus and prompted to restart the system, and so I did, and then things started to go weird. For instance, the touchpad driver needed to be reinstalled, and then I could see that my startup items DRASTICALLY got reduced, looking at the task manager. I tried reinstalling the Empowering Technology Framework, but still it doesn't work. Any of you guys experienced issues like this?
