Batteries
Caring for your Batteries 
• Always handle batteries carefully.
• Do not short-circuit the battery terminals (that is, do not touch both terminals with a metal object). Do not 
carry lose batteries in a pocket or purse where they may mix with coins, keys, or other metal objects. Doing so 
may cause an explosion or fire.
• Do not drop, puncture, disassemble, mutilate or incinerate the battery.
• Recharge batteries only as described in this manual and only in ventilated areas.
• Do not leave batteries in hot locations for more than a day or two; doing so heat can shorten the battery life.
• Do not leave a battery in storage for longer than 6 months without recharging it.
Increasing Battery Life 
• Power your notebook through the AC or optional auto/airline adapter whenever possible.
• If your notebook is running on battery power all day, connect it to the AC adapter overnight to recharge the 
battery.
• Keep brightness to the lowest level comfortable.
• Set the power management for maximum battery life.
• Put your notebook in Sleep mode when it is turned on and you are not actually using it.
• Limit your media drive access.
• Disable the Media Player auto insert notification function.
• Always use fully charged batteries.
• Eject ExpressCards when not in use.
Media Care
Caring for your Media (DVD/CD/CD-R) 
Media discs are precision devices and will function reliably if given reasonable care.
• Always store your media disc in its case when it is not in use.
• Always handle discs by the edges and avoid touching the surface.
