Press F2 while the system is booting in order to enter the BIOS Setup, and somewhere in there you should see a section for Keyboard Illumination that will allow you to customize brightness and the timeout value. However, keeping the backlight permanently on (assuming that's even an option) will reduce your battery life and may be a distraction if you're trying to watch a movie in the dark or something. On my laptop, I allow the backlight to power off after I think 20 seconds, and if I need to wake it back up, I do so by pressing something like the Left Ctrl key since it's easy to find by feel (very lower left corner of the keyboard) and there are very few applications where pressing that key by itself triggers any action.
the three levels of brightness aren't really all that different so i think i'll be fine
You may change your mind on that when you look at them in the dark after your eyes have adjusted, but whatever works for you!
Any idea where the "somewhere in there" would be? I can't find it. I see that it says backlit keyboard on the main page. All I want to do is keep it on
this will work ,
turn computer off
press the start button and start pressing F2 every second ,and BIOS will come up
press the + next to SYSTEM CONFIGURATION
the drop down window will have several keyboard options , press KEYBOARD ILLUMINATION
you will have all the options you will need , turn on ,off , different dormant cut offs , I will suggest turn off after 1 minute ,this gives you the best of both worlds , battery save and long enough to read a paragraph with out going dark
