Do not put the battery pack in trash that is disposed of in landfills. When
disposing of the battery, comply with local ordinances or regulations.
If the battery pack is to be stored separately, place it in a dry environment
of a temperature between 10-35 °C and keep it away from direct sunlight.
To extend battery life, we recommend you charge the battery to
approximately 30 to 50% capacity and recharge it every three months to
prevent the battery from over-discharging.

or authorized. The system will continue to boot, but may not charge
unauthorized batteries.
„ Heat and product ventilation
Computers, AC adapters, and many accessories can generate heat when
turned on and when batteries are charging. Notebook computers can
generate a significant amount of heat due to their compact size. Always
follow these basic precautions:
• When your computer is turned on or the battery is charging, the base, the
palm rest, and some other parts may become hot. Avoid keeping your
hands, your lap, or any other part of your body in contact with a hot
section of the computer for any extended length of time. When you use the
keyboard, avoid keeping your palms on the palm rest for a prolonged
period of time. Your computer generates some heat during normal
operation. The amount of heat depends on the amount of system activity
and the battery charge level. Extended contact with your body, even
through clothing, could cause discomfort or even a skin burn. Periodically
take breaks from using the keyboard by lifting your hands from the palm
rest; and be careful not to use the keyboard for any extended length of
time.
• Do not operate your computer or charge the battery near flammable
materials or in explosive environments.
• Ventilation slots, fans and/or heat sinks are provided with the product for
safety, comfort, and reliable operation. These features might inadvertently
become blocked by placing the product on a bed, sofa, carpet, or other
flexible surface. Never block, cover, or disable these features.
