Most recently my son turned on his ibook and his screen was black, the computer is running but he can't see anything on the screen. Specifications are as

follows: serial # LW550647QRYC Model # A1080. Does Apple still warrant, have the website to validate, this known screen problem with the Ibooks?

Hi, Richard. Welcome to Apple Support Communities.

The newest iBook is seven years old at this point. Apple quit support for them long ago (except for the forum here in Apple Support Communities).

Have you tried resetting the PMU?

The PMU (Power Management Unit) has control over the backlight function, so resetting it sometimes helps in this situation.
