Spills on the keyboard
Problem: I spill something on the computer.
Solution: Because most liquids conduct electricity, liquid spilled on the keyboard could create numerous
short circuits and damage your computer. To solve the problem, do the following:
1. Ensure that no liquid creates a short circuit between you and the ac power adapter (if in use).
2. Carefully unplug the ac power adapter immediately.
3. Turn off the computer immediately. If the computer does not turn off, remove the removable battery. The
more quickly you stop the current from passing through the computer the more likely you will reduce
damage from short circuits.
Attention: Although you might lose some data or work by turning off the computer immediately, leaving
the computer on might make your computer unusable.
4. Wait until you are certain that all the liquid is dry before turning on your computer.
