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 your computer stops responding, and you cannot turn it off,
press and hold the power switch for 4-6 seconds. If the computer still does not respond, reset the
computer by inserting a needle or a straightened paper clip into the emergency reset hole to turn off
the computer. 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.
