Here is a despairing problem that drive me out of mind. You know that I have been longing for Windows 8 operating system for a long time. So last evening, I tried to install Win 8 on my laptop by myself, a computer novice. But after the installation, I found that the brightness of the screen was too bright, then I tried to adjust it. But I failed to adjust it. I do not know why!
Can you do me a favor? Is this a problem of graphic card?
Thanks a lot!
