Cleaning Guidelines

Never clean the computer with its power on.

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

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

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

Battery Pack Guidelines

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

Operate the computer with the battery pack installed even when using external power. This ensures that the battery is fully charged.

If you will not be using the computer for a long period of time (more than two weeks), remove the battery pack from the computer.

If you remove the battery pack, make sure the battery terminals do not contact any conductors such as metal objects or water. Otherwise, the battery may become unusable as a result of a short circuit.

If you need to store the battery pack, store it in a cool, dry place. Never allow the temperature to exceed 60 °C (140 °F).

Do not leave the battery pack in storage for more than 6 months without recharging it.

Note: In order to fixed battery back, we put the block of the battery on the back of the battery. ( If you want to replace battery pack, please see page 3-5. )
