• X120e Funtion keys brightness does not?

  I just got the x120e and I have been through the fixed auto-éclaircissant himself. After that, I hit the Fn + Home and adjusted to my preference. He was not on the charger when I did so I was in a dark room I had the brightness down. Later in the day, I plugged it in to charge and I went to make it brighter. The brightness does not change however. All other agents Fn + F keys work. But not both for brightness. The strange thing is, I shut down the computer, whereas standby mode, then opens it again and it was really brilliant and I had to almost squint, but once again the keys did not work to lower it. I closed it and opened it and it is even lower. The keys still don't work. Any suggestions?

• Satellite A100-812: screen brightness does not not & screen turns off after a while

  Some power management features do not work after a bios update (5.90).
  The display brightness can be changed in the power manager, or the top menu system. In the power manager, the cursor can be moved, but the brightness is not set. Toshiba menu system appears to hang on trying to change the brightness with F6 - F7 and won't move the cursor.

  In addition, the screen does not turn off after the set amount of minutes in the power manager.

  What is going on? How can this be repaired?
  Thanks in advance.

  Hello

  Some questions; Why you have updated the BIOS?
  Are you sure you used the right BIOS?

  In my opinion you shouldn't t to update anything if the laptop works properly!

  However, try to access the BIOS, set the default settings and save the settings before exiting the BIOS.
  If this does not help, I would pick up the laptop with the Toshiba Recovery CD.

  Good bye

• FN + brightness does not not on windows 8.1 on M6600

  Hello. Thanks for any suggestion or you can provide advice.

  I have been using Windows 7 on M6600 for awhile. He has mainly worked not to mention that I was becoming "Nvidia Kernel Mode Driver stopped responding and recovered the question" sometimes and I had no other choice to restart to make it work again, it's for a while...

  When windows 8.1 became available through business, I put a hand on her and decided to reinstall fees.

  I backed up all my data and destroyed Windows and recovery partitions, leaving the dell system partition.

  8.1 Windows Installer has been surprisingly fast, 15 min. As soon as I started, I installed driver chipset Dell video drivers and other drivers. All entries in Device Manager have been without warning, some drivers have been found and some I installed on Dell site. I installed most critical programs and everything was cool and functional. NVIDIA video driver crash seems to be gone too. I have 2 other machines windows 8 so my experience windows 8 was there and I'm very happy with everything in windows 8.1

  Then finally, I noticed that the brightness of the LCD screen is not working. I made sure that I had driver Dell Intell HD 3000, driver Nvidia from Dell and Dell installed feature pack. I tried with the feature pack of Dell and without it.

  I have studied this topic, found another reference to Windows 8 having the same problem. I have 3 monitors and are they running Optimus. This worked great in windows 7.

  Some posts suggest that it is essential to install the drivers in the order. I started to doubt my installation process, if I missed something. I created the image of the system what I did rebuild in windows 8.1 and complete clean reinstall. When windows 8.1 came, I was always checking brightness. I worked very well with the native control windows 8.1. It was light and moved up and down, brightness adjustment. I immediately installed the driver chipset, rebooted, noticed that windows installed sound driver Intel HD 3000 generic in the background (which broke the brightness) and right on the top, installed DELL Intel latest driver and restarted; brightness adjustment still divided. All this according to Dell reinstall guides. As soon as windows are HD 3000 and installed the driver, fn + brightness has stopped working. so no matter the other drivers, driver Intel he kills and driver video dell Intel does not restore the brightness setting.

  I tried again. Format the partition and 15 minutes later, repeat of history. As Intel video driver is installed, the control function kills and Dell Intel driver(Win7-8_64_15.28.14_3040_Dell_setup_ZPE) does not restore it.

  So I restored windows 8.1 recorded image to get my first windows 8.1 rebuild. BTW, those who install 8.1 have no need to use (DDPA_Setup_TDC1K_A06_64bits_ZPE) security software Dell, windows 8.1 supports fingerprint scanner by default. just set it up. It works very well. 8.1 is very catchy in my laptop and I like him. I boot on the desktop (do not use 8 Start, which I use on win 8 machines) and the MS splash screen is an OK compromise in my opinion.

  This question has nothing to with the installation of sequence here. by me, Chipset and video drivers are installed in the correct order.

  I can control the brightness going in and using the BIOS. but it's an ugly way. I can control the brightness while boots windows 8.1, which is fast enough on M6600 with disc DDD, but necessary and it is difficult to judge the brightness right here.

  Some have suggested that it is thanks to Optimus. I need, I have to use 3 monitors and sometimes travel. and it worked fine in Windows 7.

  Anyone of you have any idea what I can do? Thanks a lot for your suggestions!

  PSI found the following reference http://adrynalyne.blogspot.ca/2012/10/fix-brightness-control-for-windows-8.html which seems to suggest that there might be question of deployment.

  My install Windows with driver Dell Intel 8.1 shows "FeatureTestControl" = dword:0000f960 currently.

  Could someone post what their Windows 7 for FeatureTestControl registry value uses the last Dell Windows 7 Intel driver, please?

  SOLVED. By installing the driver the most recent HD3000 from Intel, then create a HD3000Fix.Reg file with these entries, open the file or apply to Windows RegEdit (be careful as usual), then restart:-Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class\ {4d36e968-e325-11ce-bfc1-08002be10318} \0000] "FeatureTestControl" = dword:0000ffff [HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class\ {4d36e968-e325-11ce-bfc1-08002be10318} \0001] "FeatureTestControl" = dword:0000ffff [HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\intelkmd] "FeatureTestControl" = dword:0000ffff - I use this for two years for every time Intel updates the HD3000 drivers and it works well for Windows 8.0 and 8.1 of Windows on two different PCs, including the 6600 with video Intel HD3000 precision. Hope this helps others... 64Dude

• Laptop HP - 15-r213ns: hotkeys (keys of wifi sound, brightness), does not work after windows update

  Hello

  I have a HP laptop - 15-r213ns (ENERGY STAR) with windows 8.1

  Last night, after an update of windows, the shortcut of the brightness (F2 and F3) volume (F7 and F8), wifi (F12) and keys all others have stopped working.  I can always change the brightness and volume using windows, but I can't do more using the keys.

  The function keys are working, as refresh F5 or F3 Browse. I noticed that before I had to press the FN key for this and now she does without the FN + Fx, so I guess that the update of windows must have changed something here.

  They used to work fine before the update. I reinstalled the display drivers (NVIDIA G-FORCE 820 - M) and looked for new drivers or update drivers using HP Support Assistant, but everything is up-to-date.

  I was looking for hot key factors in the page of HP drivers for my product but could not find any keyboard, drivers or software related shortcut keys.

  any suggestions?

  Thanks in advance,

  Marco

  Hi, Marco:

  The system of the event utility is supposed to get the Fn keys to work.

  Details:

  This package contains the HP System Event utility for the laptop models running a supported operating system. HP System Event Utility allows the special programming function keys.

  File name: sp70439.exe

  You can find this file in the Software - Solutions section of the driver for your model page.

• L855-135 satellite display brightness does not work using the new ATI driver

  Hello

  I just bought the L855-135 with a Radeon HD 7670 M and wanted to update the graphic with map
  the last driver AMD. After that, I realized that the brightness setting didn t work anmore. So I uninstalled
  the new driver and installed again the old driver from this site. Now, the brightness setting works fine again but I Don t really want to get stuck on this older version of the driver. Its around the age of 8 months. Before I bought my laptop I've never heard their update policity. Can someone tell me when they intend to update their-own-amd-drivers toshiba? I really want some new drivers but I Don t want to lose the ability to adjust the brightness. For me, it's a reason to give the laptop back, but I like really this laptop with the exception of its own pilots.

  Can someone tell me how long it will take to get a few new drivers? And I mean not more recent that the 'old' but still 6 months of NEW drivers.

  Thank you.

  > After I realized that the didn t of brightness adjustment works more. So I uninstalled the new driver and installed the old driver from this site again. Now, the brightness setting works fine again but I Don t really want to get stuck on this older version of the driver.

  I found another thread on the same topic.
  It seems that the command buttons FN brightness don t work using the NON-Toshiba graphics card driver.

  You know this Toshiba page graphics card driver is a driver updated, created and configured especially for models of Toshiba laptops.
  This driver supports protection against overheating. Other drivers don t

  However, it seems that there is no other solution than to use the Toshiba configured and modified drivers.

• HP Pavilion 15 Win 8.1 brightness does not change the question

  Hello

  I have this model of laptop - HP Pavilion e017tx. I just upgraded to 8.1 Win. Faced the problem of explorer.exe when stopping. Now after this, I face the problem of brightness adjustment!

  I am not able to change the brightness of this laptop since the function keys or the control panel? What continues?

  Any ideas?

  Thank you

  Hey thanks for the reply! ... I actually already had correct/more drivers later for video.

  The solution for me was to re - install the drivers of HP system event... I am now able to adjust the brightness. I was hoping that the upgrade to 8.1 win to win 8 would be nice and simple straighforward, but there are many of these little problems that keep popping up after the upgrade. URL compatibility which provided HP says that the laptop is compatible or not, but in the job or the guide, they should mention in detail (if possible for all / most of the hardware configurations) on what to expect and what drivers to reinstall or upgrade etc. after upgrade to 8.1 Windows

  Thank you

• T440 display brightness does not

  After that the first time I put my piece of crap T440 for sleeping, the keys on the keyboard to change the brightness of the screen stop working - no effect, & not on the screen display. Given generally terrible all of the features of this machine, I'm not too surprised. I downloaded & installed the power management program, the pm, the driver display driver and a box of chocolates. Anyone have any ideas?
