Vandaag toch maar even AppleCare gebeld want ik was het zat!
Mijn iBook gaat nu al bij 40% op sleep (na 2 uur)
Alles even uitgelegd en ze sturen me nu een nieuwe batterij YES!!!
Voor de mensen waarbij de batterij ook slecht is en nog in de garantie zit kun je het volgende nummer bellen: 020-3469104 [optie 2]
Ik vroeg ook nog hoe je het beste met je batterij straks om kon gaan, en kreeg KB 86284 toegemaild, waarin het volgende staat
This document explains how to calibrate your new iBook or PowerBook G4 Lithium Ion battery for best performance.
The battery of an iBook or PowerBook G4 computer has an internal microprocessor that provides an estimate of the amount of energy in the battery during charging and discharging. The battery needs to be recalibrated from time to time to keep the onscreen battery time and percent display accurate. You should perform this procedure when you first use your computer and then every couple of months thereafter.
Follow these steps:
- Plug the power adapter in and fully charge your iBook or PowerBook G4 computer’s battery until the battery indicator lights turn off and the adapter plug ring goes from amber to green, which indicates that the battery is fully charged.
- Disconnect the power adapter and use your iBook or PowerBook G4 computer. When your battery gets low, you will see the first low battery warning dialog on the screen. Continue to use your iBook or PowerBook G4 computer until it goes to sleep. At that point the battery has been sufficiently drained for calibration.
- Connect the power adapter and leave it connected until the battery is fully charged again.
Note: You have to fully charge and then discharge your battery only once to calibrate it. After that, you can connect and disconnect the power adapter when the battery is at any charge level.
Important: 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 into shutdown. At this point, any open files could be lost. Therefore, it is important that you find an electrical outlet and connect the adapter before the forced shutdown occurs.
