I've searched around these forums and not been able to find a solution for my problem. Here's the whole story.
I've had my IdeaPad Notebook P500 for over a year, and rarely had an issue with it. Today, I accidently touched the F11 key, which happens to be the "Brightness minus" key.
Immediately, the screen went very dim, to the point where it actually hurts my eyes to be typing this.
I can adjust the brightness sliders up and down on the screen, using both the F11/F12 keys and the slider box available from the "Brightness" selection under "Settings". Even though the sliders go up and down, the screen stays the same very dark level.
Windows 8 64-bit is my OS.
I have uninstalled and re-installed the Intel HD driver.
I have shut down the laptop and turned it back on while holding the F12 (Brightness plus) button. Yes, it sounds crazy but someone mentioned it on another thread so I figured what the hell. It was useless, though.
I have rebooted several times.
Anyone have a clue as to why one simple mistype has apparently hosed my computer, and better yet, anyone know what I can do about it?
Solved! Go to Solution.

Here is a cut and paste from another topic I found through laborious searching. My P500 is basically a Best Buy packaging of a Z500, so I figured I'd give this a shot, and it worked! Hope this helps others.

Finaly finaly after 5 hours searching, I found the best solution:
1- install latest driver of Intel Hd Graphic 4000
2- install latest driver of your graphic card
3- This step will fix the problem:
- go to registery by regedit and change the value to 0xf048
this will fix the problem.

I had this problem today, and the Geek Guy from the local Best Buy gave me a fast and easy solution. When booting the computer up, hold down the F12/increase brightness button. Upon bootup, the brightness is normal.

I have Lenovo P500 Ideapad laptop, and I also hae an issue about the brigtness. I did try all of the versions. Firstly, I would just constantly refresh the VGA x-32 driver, but just today I again got the problem of brightness, and i was trying to do it again, but it shows error and says that my computer does not meet the minimum requirments for the installation. I also tried to restart my computer holding the F12 button, it did work as it got brighter, but now I again can not adjust the brightness, it just stays the same. not up or down. would anyone help me with this problem please?
