When your business keeps you tied to the computer for long hours, it is helpful to adjust the display brightness to a level comfortable for your eyes. Changing the brightness is useful when you work in different locations with various lighting conditions. Fortunately, keyboard shortcuts on HP Pavilion notebook computers using Windows 7 or Vista help you adjust the screen brightness quickly without interrupting your work. Using the Fn or Function key in conjunction with other keys will let you adjust the brightness of the screen and perform other special functions.

I cant seem to find the brightness adjuster in my laptop after I reformatted it with windows 7 ROG Rampage(64 bit). My laptop is HP Pavilion dm4-1209tx. I also checked with the HP website and my drivers are all up to date. I also tried installing HP Quick Launch but was unable to do so probably because it is not supported by my OS. I've run out of ideas anymore. Any advice? Thanks!

I've had the same problem once. For me, the trouble maker was TeamViewer's mirror driver. Uninstalling the mirror driver fixed the problem for me and the brightness adjust controls started working again.
I've contacted TeamViewer about this problem and it has been confirmed by TeamViewer support staff although they don't consider it a bug. Here's their response:
Thank you for your interest in TeamViewer.
This is a known issue, if the monitor driver is installed you lose your brightness settings. IF you want to recover them, you need to uninstall this driver and restart your computer.
If we may of further assistance, please don't hesitate to contact us again.
To uninstall the monitor driver, follow these steps:
If you don't have TeamViewer on your computer, make sure you don't also have similar software (LogMeIn, RealVNC, etc.) that can install a monitor driver. To check if your computer's monitor is using one of these mirror drivers, do the following:
If it does, you need to find and uninstall the respective monitor driver.

When Windows can't find the correct driver for a graphic card it will use the Standard VGA Graphics Adapter driver, which is generic and provides basic video functionality only.
According to the official specifications, the laptop has switchable graphic cards.This means the computer actually got two different graphics cards: Intel HD Graphics and AMD Radeon HD 6370M. The first one is integrated into the CPU and is energy efficient; the second one is discrete (or dedicated) and is more powerful.
The system can let you choose which graphic card to use, while defaulting to the integrated one to prolong battery life. Switchable solutions are based on custom hardware, and require specific drivers provided by manufacturers in order to work as intended.
Additionally, the the brightness adjustment was available before formatting. This suggests that the issue can be tracked down to a missing driver.

Some manufacturers provide automated tools to check whether the drivers are up-to-date, but sometimes they might fail to properly detect the installed hardware, thus requiring manual intervention.

I can't stand Microsoft flaws. And or driver issues for not getting along with Microsoft. Who knows but I have the same problem the brightness controls completely disappear and the screen defaults to very bright.
In device manager the quickest way I found was to simply disable your display adapters and enable them instantly. This reboots the drivers and brightness control will be back to normal. But for how long that's the problem. Changing drivers and all the mentioning of power settings is absolutely useless and I wish people that haven't experienced a cure for this would stop leading everyone around in circles. That is why I am writing this.
