Spills on the keyboard

With a mobile computer, there are increased chances of spilling liquids on the keyboard. Because most
liquids conduct electricity, liquid spilled on the keyboard could create numerous short circuits, potentially
causing irreparable damage to your computer.
If you spill something on your computer:
Attention: Be sure that no liquid creates a short circuit between you and the ac power adapter (if in use).
Although you might lose some data or work by turning off the computer immediately, leaving the computer
on might make your computer unusable.
1. Carefully unplug the ac power adapter immediately.
2. Turn off the computer immediately. If the computer does not turn off, remove the battery pack. The
more quickly you stop the current from passing through the computer the more likely you will reduce
damage from short circuits.
3. Wait until you are certain that all the liquid is dry before turning on your computer.
Note: If you want to replace your keyboard, you can purchase a new one.
