Battery Packs

Even if a battery pack is heavily used, it should not be necessary 
to calibrate it more than once a month. It is not necessary to 
calibrate a new battery pack before first use. However, make sure 
that the battery pack is fully charged, especially if it is the only 
power source.

Calibrate the battery pack under the following conditions:

■

When the battery status display seems inaccurate.

■

When you observe a significant change in normal battery 
run time.

■

When the battery pack has not been used for one month 
or more.

To calibrate a battery pack, you must fully charge, fully 
discharge, and then fully recharge the battery pack.

Fully charge the battery pack when the notebook is in use. To 
charge the battery pack:

1. Insert the battery pack into the notebook.

2. Connect the notebook to external power through an 

AC adapter. (The battery light turns on.)

The battery light turns off when the battery pack is fully charged.
