Extent Battery Life -Macbook Pro

Issue umur battery adalah issue populer bagi pengguna notebook. Karena sifatnya yang mobile maka sangat wajar bila pengguna notebook berharap notebooknya mampu bertahan lama tanpa “infus” (tanpa plug ke listrik). Bahkan salah satu indikator bagus tidaknya sebuah notebook adalah ketahanan battery-nya.

Tapi, battery perlu dipelihara. Salah memperlakukan battery, maka umur battery akan cepat berkurang. Jika demikian, pengguna notebook akan dipaksa untuk merogoh “kocek” yang lumayan dalam untuk membeli battery baru. Atau pilihan lainnya, bertahan dengan sistem “infus” 🙂

Ini juga menjadi kekuatiran saya. Saya tidak ingin battery Macbook Pro saya cepat rusak, murni karena harganya yang bakal lumayan bikin pening 🙂 Karena itu saya googling, dan dari berbagai macam tips yang beredar di mbah google sepertinya berikut ini yang paling “afdol” (kalau kata si Kemal, peserta Stand Up Commedy Indonesia 2) karena tertulis di website Apple. Tapi sepertinya ini juga applicable untuk battery-battery notebook lain. CMIIW.

Secara summary, perlu dilakukan pengosongan secara rutin. Satu bulan sekali sudah cukup. Caranya sbb:

PowerBook G4 (15-inch Double-Layer SD), MacBook (all models), and MacBook Pro (all models) 

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:

  1. 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.
  2. 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.
  3. Disconnect the power adapter while 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, the low battery warning dialog appears on the screen.
  4. At this point, save your work.  Continue to use your computer; when the battery gets very low, the computer will automatically go to sleep.
  5. Turn off the computer or allow it to sleep for five hours or more.
  6. 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.
