Sony :: Vaio Z In Stamina Mode

Nov 3, 2009

Since I installed the new driver of Windows 7 for my Z, I have some wierd problem in Stamina mode (see attached photo). I wonder if someone has the same problem. I installed the driver in the same time that I update my Z's RAM to 6GB (bought a 4GB). It may be my new RAM, but I don't have any problem in Speed mode, no error with Memtest, and no BSOD either.

Sony :: VAIO SZ5- Can't Switch Between Stamina/speed Mode

Aug 8, 2009

I have a VAIO VGN-SZ55GN but I found out that I can't switch between speed/stamina mode.

I had had the intel graphic driver installed automatically after I'd installed a new OS onto the laptop but I can't get the nVidia driver to work.

I tried shutting down the laptop, moved the switch to speed and turned on the laptop again but I still can't get the laptop started up w/ nVidia graphic card.

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.

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.

Sony :: Vaio SZ440ARGH! Speed Mode Brightness Controls In Windows 7 (x64)

Nov 9, 2009

just can't seem to get my Brightness controls to work in speed mode in windows 7.

I've tried 169.09, 180.70 and the most recent forceware drivers.

I've installed the registry file that was recommended in one thread.
I've tried all kinds of orders. Still, nothing.

I've currently installed (in this order)
SPEF
SonyPI
Shared Library
SonyUtils DLL
Event Service
The Registry Patch
NVIDIA Drivers

They work fine in STAMINA, but not in SPEED. I can't even access them through Windows Mobility Center or Power Options. I can change them a very small amount though the NVIDIA control panel through the "adjust color settings" tab. Otherwise, theres no mobility options in the NVIDIA panel.

Sony :: Vaio Z11MNB: Brightness Adjust Doesn't Work In SPEED Mode

Mar 12, 2010

I've just installed Windows 7 Ultimate 64bit on my Vaio Z11MNB. As Google told me there is a problem with the FN + F5/F6 brightness adjust in speed mode.

All Sony software ist installed correctly and in the newest version I found.

As in many threads mentioned I followed the right order. But I still cannot adjust the brightness in speed mode

This thread Problem with Vaio Z Windows 7 brightness lead me to the right graphic drivers I thougt... Okay these drivers[url] are for the ZD790 but this shouldn't matter it's the same 9300GS chipset...

The following sony software is installed:
SETTING_UTILITY_SERIES_5.1_5.1.0.11200
SFEP_DRIVER_SONY_8.0_10Q1_O_7_8.0.1.1
SPIC_DRIVER_8.0_09Q3_7_8.0.1.1
SONY_SHARED_LIBRARY_5.5_5.5.0.10160
VAIO_CONTROL_CENTER_4.1_4.1.0.10160
VAIO_EVENT_SERVICE_5.1FH_5.1.0.12010
VAIO_POWER_MANAGEMENT_5.0_5.0.0.11300
VAIO_SMART_NETWORK_3.1_3.1.0.11250

Another smaller problem: From time to time there is a yellow exclamation mark at the SD-Hostcontroller in the device manager. I've googled a lot but there seems to be no other driver than the windows included. VEN_1180&DEV_0822

Sony :: Vaio Z Stamina/Speed Switch In Windows 7

Feb 12, 2009

Does any else have this feature working under Windows 7?

I have everything functioning (incl. FN brightness and volume controls) in my partitioned install except this.

I have the switch itself set to "Stamina" but neither mode even brings up the little green light beside it. It is completely unresponsive.

Sony :: Desktop Background Goes Black After Switching Between Stamina And Speed Modes

Mar 31, 2010

I have my destop wallpaper/background set to change every 30 minutes, pulling from the entire picture library (which is a few gigabytes). I have noticed that every now and then...say, maybe 10-20% of the time. The desktop background goes completely black after the switch. This happens whether the switch is set to Auto or I manually flip the switch (which makes sense, actually).

The only thing that restores the picture to view is logging off and back on. None of the following have any impact or cause the picture to display:Right-clicking on the desktop and selecting.....

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.

Specs

Windows 7 Home Premium 64 bit

Core i7-720QM

4GB DDR3 1333Mhz RAM

Full HD 1080p High Brightness LED

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 10.18.10.3960
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 9.17.10.3223 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.
