Lenovo Ideapad Brightness Issue

As I posted in anoter thread for the P500 Brightness Issue:I'd just like to start by saying this error was casued by a Driver Update downloaded by Windows Update for the Intel HD Graphics 4000. The new update causes Windows to fail to control the backlight.Symtoms:- Pressing the Brightness keys ether does not change the display brightness, or causes the display to go to minimum brightness at all times.How to Fix:Hit the Start Button + R on your keyboard, this will open the 'Run' Box.

In the Run Box you should type devmgmt.msc This will directly open the device manager.(It must be spelled EXACTLY this way, and you must type the.msc to open this window. Alternatively, you may find the Device Manager via Administrative Tools Computer Management in the Control Panel after selecting View Large/Small Icons from the dropdown list in the top right corner.)This will open the Windows Device Manager, Once the Window is loaded and the devices appear, double click 'Display Adapters' Then right-click 'Intel(R) HD Graphics 4000', Click Properties from the dropdown list.Once in the Properties window click the Driver Tab, Then click on the ' Roll Back Driver' button. If you are prompted if you want to install the previous version of the drivers, Select ' Yes' Windows will Install the older (and in this case, working) driver and reboot, or prompt you to reboot, depending on your settings.Please Note the following before attempting the above instructions;- YOU MUST Have Administrative Privilages to use the Device Manager- DO NOT Confuse 'Roll Back Driver' and 'Uninstall'. Uninstalling The Intel(R) HD Graphics 4000 Driver May cause failure to display graphics at all, or the standard VGA driver will load and you will have sub-optimal video graphics until you install the proper driver.- DO NOT Uninstall or Rollback any other drivers, they are unrelated to this guide and may casue system unstability and loss of functionality of devices.Alternatively, You may find the old drivers in your backup partition, Usually Labbed 'Lenovo (D)', in my case this partition was lost when I installed a faster RPM drive to my machine.Hope this information helps.
