MacBook Pro 15" Unibody Late 2008 and Early 2009 Battery Replacement

2 minuten


Mijn probleem

My computer stopped charging, so we could only use it while plugged into the wall. Apple doesn't make these batteries anymore, but the tech recommended apple certified repair shops or iFixit. After a couple months of contemplation with everything loaded and ready in my ifixit cart, I finally purchased last week. Everything is wonderfully efficient so far.

Mijn oplossing

The battery was really easy to install with the repair manual, even when the old battery seemed "stuck" because the release latch was still partially engaged. Took two minutes even with this personal snaffoo.

Mijn advies

It might be helpful to include these instructions for calibrating the new battery, even if it's just a suggestion.

From apple via a Mac forum:

The battery calibration for the PowerBook G4 (15-inch Double-Layer SD) and any model of MacBook or MacBook Pro has been updated because of a new battery released with this computer. With these computers, follow these steps to calibrate your battery:

• Plug in the power adapter and fully charge your PowerBook's battery until the light ring or LED on the power adapter plug changes to green and the onscreen meter in the menu bar indicates that the battery is fully charged.

• Allow the battery to rest in the fully charged state for at least two hours. You may use your computer during this time as long as the adapter is plugged in.

• Disconnect the power adapter with the computer still on and start running the computer off battery power. You may use your computer during this time. When your battery gets low, you will see the low battery warning dialog on the screen.

• Continue to keep your computer on until it goes to sleep. Save all your work and close all applications when the battery gets very low, before the computer goes to sleep.

• Turn off the computer or allow it to sleep for five hours or more.

• Connect the power adapter and leave it connected until the battery is fully charged again.

Tip: When the battery reaches "empty", the computer is forced into sleep mode. The battery actually keeps back a reserve beyond "empty", to maintain the computer in sleep for a period of time. Once the battery is truly exhausted, the computer is forced to shut down. At this point, with the safe sleep function introduced in the PowerBook G4 (15-inch Double-Layer SD) computers, the computer's memory contents have been saved to the hard drive. When power is restored, the computer returns itself to its pre-sleep state using the safe sleep image on the hard drive.
