brightness setting display bar not showing?

hi just a few question....
1) I noticed that when i change the brightness of my AAO lcd, i can't see the brightness level indication as compared to the volume indication that appears green at the bottom of the screen. Is this normal???

2) And how many levels of brightness are there? I only noticed like 5 levels but when i press the fn+right arrow from the lowest level, i need to hit the right arrow 5 times before i get the 2nd level of brightness.

3) Do i have to register for the warranty online?

Hope u guys can enlighten me on these issues. Thanks alot!

 

There is no brightness level indicator on the screen. It'd be nice if there was, though. Some screens had a problem with flickering when the brightness was set too low so they got rid of the lower levels. If you update your BIOS (to 3307 or newer, I think) and your display is recognized as one that doesn't have the flicker problem then you'll get all ten levels.
