iBook, iBook SE and iBook (FireWire) computers

There are a number of ways to determine if the battery has a full charge:

  • If the battery is being charged, the AC power port on the rear of the iBook will glow amber. It changes to green when the battery has a full charge.
  • The battery icon in the menu bar will have a lightning bolt through it when the battery is charging. The lightning bolt disappears when the battery is fully charged.
  • The battery icon in the Control Strip will show the same lightning bolt when charging. It also disappears when the battery is fully charged.

The Lithium-Ion iBook battery will take approximately 2 hours to fully recharge when in sleep mode or when shut down. If the computer is running, the charge time doubles to approximately 4 hours.

iBook (Dual USB) and later

When the battery on these computers is fully charged, the four battery lights (located on the bottom of the computer) will glow green.
