zUse a soft cloth moistened with water or a non-alkaline detergent to wipe the exterior of the computer.

zGently wipe the display with a soft, lint-free cloth. Do not use alcohol or detergent on the display.

zDust or grease on the touchpad can affect its sensitivity. Clean the pad by using adhesive tape to remove the dust and grease on its surface.

Battery Pack Guidelines

zRecharge the battery pack when it is nearly discharged. When recharging, make sure that the battery pack is fully charged. Doing so may avoid harm to the battery pack.

zThe battery pack is a consumable product and the following conditions will shorten its life:

when frequently charging the battery pack

when using, charging, or storing the battery in high temperature condition

zTo avoid hastening the deterioration of the battery pack thereby prolonging its useful life, minimize the number of times you charge it so as not to frequently increase its internal temperature.

zCharge the battery pack between 10 °C ~ 30 °C (50 °F ~ 86 °F) temperature range.

A higher environment temperature will cause the battery pack’s temperature to rise. Avoid charging the battery pack inside a closed vehicle and in hot weather condition.

Also, charging will not start if the battery pack is not within the allowed temperature range.
