I am an Ibook G4 newbie actually a laptop newbie and I have a question about the backlight.
When my Ibook wakes from sleep it takes a few seconds to get to the right brightness. I know lcd displays are not supposed to have a warm-up so I was just wondering is this normal
Other then that I love my Ibook



Thanks
Matt

I do not know why, but all my laptops and my friends soes like that, it take 5-10 sek to get full backlight. so I suppose its perfectly normal.

It's normal, pretty much every laptop has it. Even my 17" Powerbook. Don't worry about it, 5 second is not that long of a wait for your display to adjust itself again...

you have to remember that there is a CCFL light that is lighting the display up...it is just like a flourescent light in an office...they don't just turn on like a incadecent bulb does...there is a little bit of warm up that has to happen so don't worry about it...if it starts to take longer and longer to warm up then I would start to wonder...something else to remember about any LCD is it takes apx 30 minutes for them to warm up
