www.gateway.com Cleaning the convertible notebook screen Caution A convertible notebook LCD screen is made of specially coated glass and can be scratched or damaged by abrasive or ammonia-based glass cleaners. Use the special cleaning cloth included with your convertible notebook to wipe away dust and fingerprints. Dampen the cloth with water or a mild window glass cleaner solution but never spray anything directly on the surface. If liquid collects around the edges, wipe it up immediately. Maintaining the battery(ies) The life span of a convertible notebook battery is about 1.5 to 3 years, under normal conditions. As a battery begins to die, you will have to recharge the battery more frequently because it cannot hold a full charge. Do not expose the battery to high heat or freezing temperatures. Hot batteries discharge very quickly, and cold ones cannot create as much power. Short battery life is more likely to be caused by heat than by charge/discharge patterns. Keep your lithium-ion battery cool. Avoid a hot car, for example. Charge often, but do not try to fully discharge the battery frequently. This only adds strain. Several partial discharges (regular use), with frequent recharges, are better for lithium-ion than one total discharge. Recharging a partially charged lithium-ion battery does not cause any harm because it has no memory. Batteries with fuel gauges (convertible notebooks) should be recalibrated once every 30 charges. If ignored, the fuel gauge becomes increasingly less accurate and in some cases will cut off the device prematurely. For more information about recalibrating the battery(ies), see "Recalibrating the battery(ies)" on page 65. Using the right charger is important. By now you probably know that each kind of battery has its own technology, its own rate of charge, and so on. Charging lithium batteries correctly is one way to extend their life and to avoid damage. Clean the gold or silver connector on the battery(ies) (the part of the battery that makes contact with the convertible notebook) with alcohol or electronic contact cleaner. Cleaning helps maintain good contact, which improves the transfer of power from the battery(ies) to the convertible notebook. 85
