My FN+Home and FN+End not working for changing brightness

Saddam Al-Nasser wants more answers to this question
Let me guess it is too bright in a dark room?
dell vostro 1015
NO OS stated, at all. by OP or Hyjackers.
the dell site has xp vista and w7 driver only for this old PC
if the device manager shows, keyboard drivers missing then try the one below marked,
Mouse, Keyboard & Input Devices 07 Jul 2012

below covers both types of personal computers.

oops dell lost the users manual after 9 long years, sadly
see the 2 keys below, blue, sun Icons
you push Fn blue key left side of keyboard
then push SUN key down. lower red arrow below.
if this fails to lower the backlamps
that means the drivers are missing. xp,.vista,w7 are all dell supports. (NO OS stated by OP nor hyjackers. as is par here)
Fn+down-arrow : key. if dead driver is wrong.!!!

go to start-->control panel--->display--->adjust brightness

i need to know what operating system you use this will work for only Vista and 7 and 8 and 8.1

hey Robe, try these:
from Lenovo:
http://support.lenovo.com/en_US/downloads/default.page?
Hotkey Utility:
http://download.lenovo.com/ibmdl/pub/pc/pccbbs/mobiles/8jvu39ww.exe
Access IBM button (for Windows XP):
http://download.lenovo.com/ibmdl/pub/pc/pccbbs/mobiles/1rth52us.exe

I also started facing the same problem all of a sudden, but just disabling and enabling the Nvidia display adapter under device manager solved the issue. Not sure if it will help u, but should give it a try,

Maybe a crumb under the Fn key. Give it a stab and see. Otherwise go to start-control panel-monitor-adjust brightness. Hope this helps.

Try installing the below Keyboard Driver\Software from the below link.

You should try to determine why your Fn keys are not working... just to make certain, the Fn+Home key will increase brightness and Fn+End will decrease.

You can try the blue IBM-Access Key. In the Configure tab, you can manage the display settings.

If you cannot see your display because it is too dark, try attaching an external monitor via the vga connector.

Well I don't know exactly why it is messing up, but here is a possible solution. I know that the link below doesn't pertain to your computer, but follow the instructions in the forum link:

Here are the drivers directly from invidia for your card. Use these in the formula from the above post:

http://www.nvidia.com/object/geforce_notebook_winxp_185.85_whql.html

check the version of driver you have for the geforce graphics card. it is likely the generic microsoft driver. you need to update that by obtaining the correct and most current driver from the NVIDIA site

You probably just need to download the hotkey software.

Your is HERE.

Download, install, and let us know what happens.

If that doesn't work we'll try something else.
