Before removing the battery, ensure your notebook is turned off.
To remove the battery, follow the sequence as shows in the figure
below.
1 Slide and hold the battery release latch
2 Gently pry the battery from the computer chassis.
When your N521 Series notebook computer estimates that the
battery only has enough charge to continue for a few minutes, it will
alert you with a battery low warning beep. If you are consuming a
lot of power by using the audio system, the PC Card slots, the hard
drives, and optical disk drive, your notebook computer might run out
of charge much sooner than you expect. You should always respond
to the battery low indication by connecting to AC power or turning
off your notebook computer, or suspending to disk. If you do not do
so, the notebook computer will automatically suspend to disk and
turn off. The contents of the memory will store in the hard disk drive.
You will be unable to restart your notebook computer until it has con-
nected to the AC adapter or installed a charged battery. To replace
the battery pack, refer to the previous sections on “Installing the
Battery Pack” and “Removing the Battery Pack.”
Note: Be sure to save your data before replacing the battery pack or
connecting the AC adapter. Failure to do so can result in data loss.
Note: Danger of explosion if battery is incorrectly replaced. Replace
only with the same or equivalent type recommended by the manu-
facturer. Dispose of used batteries according to the manufacturer’s
instructions.
