Calibrating the Battery

IMPORTANT: Fully drain and recharge the battery at least every 60 days.
IMPORTANT: You can check the battery gauge (battery meter) by double-clicking
the Battery icon
All batteries lose their charge when not being used for a long period of time.
You may notice your battery gauge does not correctly display the battery charge
level when you first receive your computer or if you have not used your
computer for a long period. If your battery gauge becomes inaccurate, you must
recalibrate your battery. To do this, fully charge your battery then drain it to
empty (your unit will enter the hibernation mode automatically).
To recalibrate your battery, complete the following steps:
1. Plug in the AC adapter. Allow the battery to charge until the battery
charge light turns off, showing that the battery is fully charged.
2. After the battery charge light turns off, unplug the AC adapter.
3. Turn on or restart your computer.
Steps 4 through 9 prevent your computer from entering the sleep mode. These
steps allow your battery to drain faster.
