Quick Tips

It takes approximately 4 hours to charge a fully discharged single battery

with unit off or in suspend mode.

Optimizing Battery Life

• Set power management setting for best battery life.

• Adjust display brightness levels to lowest comfortable setting.

• Utilize Suspend mode when not using your notebook.

• Read the Power Management section in your User's Guide for additional

features.

• Remove PC Cards and Express Cards when not needed

• Turn off Wireless LAN when not in use

• Close unused programs

• Remove unused USB powered devices

Adjusting Display Brightness

• Fn + F6 to decrease brightness

• Fn + F7 to increase brightness

Adjusting Volume

• Fn + F8 to decrease volume

• Fn + F9 to increase volume

Heat damage to your Lithium ion battery

• Extended exposure to heat will have a negative impact on your battery.

Do not expose your notebook to exces sive heat such as leaving it in

the car on a hot summer day. If you are near an outlet and playing

a graphics-intensive game, it is recommended that you remove the

battery from the unit to avoid exposing it to excessive heat.

Discharging your battery

• Full battery discharges (to unit shutdown or 0%) should be avoided. It

is recommended that batteries only be partially discharged to levels of

20-30% before recharging.

Prolonged storage

• If your notebook isn't going to be used for a while, you should remove

its Lithium ion battery. To store a battery for long periods of time, its

charge capacity should be around 40% and store it in a cool dry place.

Purchasing a replacement battery

• Only purchase a replacement battery from Fujitsu. Ensure that you

purchase a battery that is specifically designed for your model

computer. It is recommended that you purchase a replacement battery

only when the current battery has noticeably degraded; unused

batteries will still suffer degradation when stored.
