Thanks for the article, Roger.
My laptop is not as severe as in the article, never goes out, but may be going in that direction. Mine appears like a thin piece of wax paper is on the screen - still legible, but that bright and sharp.
Will do some research on the inverter/backlight.
My dilemma is to decide whether to upgrade to Win8 with this computer. I am currently running Win8 Enterprise Trial w/ IE10. Problem is the same on Win7.
