  Hello

  just installed windows 7 64 bit on my SL500. previously, I had vista 32-bit home.

  granted, everything works, but I can't change the brightness. its default value (which is 85% I think)

  also, the sound is not loud enough.

  any ideas people?

  Thank you

• Can not change the brightness on my laptop Vista

  Using the Control Panel, power or FN + F7 or F8 options, I can't adjust the brightness on my laptop.

  I used to be able to use these options and could change the brightness, but now all of a sudden, I can't. I tried to update the driver for my monitor, but it says that it is up-to-date.

• Can not change the brightness control does not work

  Hello

  Is IM having sony vaio e15117 possible to control the brightness of the computer

  When 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-Troubleshooter

  Troubleshooting 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.

  I hope this information helps.

• Satellite L50 - B - 12 G - can't change the brightness of the display

  Hi people,

  For some reason that I can't find out, since yesterday I can not change the brightness on my deskop.
  It's a Satelite L50 - B - 12 G with Windows 8.1, 64 bit.

  (F2 and F3) function key does not move the scroll bar, and when I try the same thing on the control panel is like this:
  It is not simply to change the brightness

  At the same time, when I'm with an open office document or on a web page, don's work the cursor as usual... it is slower to move from one cell to another cell in Excel for example.
  The sane is to arrive with the page down key.

  Can anyone help on this? It becomes very annoying.

  Best regards
  Jose

  How did you try to increase or decrease the brightness of the screen?
  Did you press the FN key also?

  Well, as you said the F2 and F3 keys increases or decreases the brightness of the display
  The extra pressure of the FN button depends on the key mode feature which is located in:
  Office Assist-> tools & utilities-> Control Panel-> keyboard

  Permit special mode button allows you to use special features without pressing the FN key.

  That's why I recommend that you check this setting!

• I can not change the type of standard user to the admin account.

  I had a very difficult time, adding new accounts to the system.  Now that I have, I can not change the type of standard user to the admin account.

  As you don't declare that you tried, I am unable to say where you went wrong. Here is a method to promote the accounts without going through the various GUI screens:
  1 restart in SafeMode with network.
  2. log on as an administrator.
  3. click on start.
  4. type the three letters cmd in the search box.
  5. press on Ctrl + Shift + Enter
  6. click on "run as Administrator".
  7. type the following commands and press ENTER after each:
  NET user
  (This will show you all existing accounts)
  net localgroup administrators 'xxxx '.
  (This will encourage user xxxx to Administrator status. Replace xxxx with the correct name account).

• "Not available" brightness - can't change the brightness level

  Omni HO 27-1015 t CTO Desktop PC product number: Windows 8 new installation B2Q20AV

  I can't control the brightness in the settings - brightness icon bed: not available

  No error message

  Setting of power doesn't have the brightness slider

  Forward power, lack of control of the brightness setting

  Reinstalled the Intel drivers from the HP site with administrator installation and reboot.

  Thanks for any help

  I had this same problem on a spectrum One and it was driving me crazy! Windows wouldn't let me change the brightness no matter how, I went to this topic, and I saw that you get the message "Not available". Finally, I stumbled across the "HP My Display" program and was able to adjust the brightness in there. What is loaded on your PC? So far, it's the only way I found to change the brightness on this machine.

• I can't change the brightness Displal in my Probook430

  Hello.

  I recently bought a HP Probook430 and installed Windows 7 Ultimate 32 bit and I don't seem to be able to change the brightness of the screen, using the fn + f9/f10 (although volume settings are changed in the same method smoothly).

  Although the parameters of brightness do not seem to change, this bar will appear when you press fn + f9/f10.

  

  What should I do in order to make the brightness display editable settings?

  Thank you!
