Conditioning the Battery Pack
You need to condition the battery pack when the actual remaining power in your
battery is less than what Windows Power Meter indicates, or you buy a new battery
pack.
1. Make sure the computer is turned off. Connect the computer to AC power and
wait until the battery is fully charged. The battery indicator turns orange first;
then, turns to green when the battery pack is fully charged.
2. Turn on the computer.
3. When the message Press <F2> to enter SETUP appears, press F2 to open the
Setup Utility.

4. Disconnect the AC adapter, and leave the computer on until the battery is
completely discharged and the system shuts down automatically.
5. Connect the computer to AC power and let the battery fully charge again.
6. Turn on the computer and follow the steps 3 to 5 again.
7. Restart the computer. The conditioning process is complete.
Do not connect the computer to wall outlet while discharging the battery.
The conditioning will be cancelled.
Changing the Battery Pack
The capacity of a battery pack gradually decreases when used repeatedly (the
deterioration rate depends on the operating environment). If the battery life
becomes extremely short even after the conditioning, you should buy a new
standard battery pack (CE-BL17). An optional battery pack (CE-BL18) is also
available in some countries.
When you replace the battery pack with a new one:
1. Turn off the computer and disconnect the AC adapter from the computer.
2. Close the display cover and turn over the computer on a flat place.
