If the computer still does not start up, call the Customer Support Center and a Customer Support specialist will assist you. 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. The more quickly you stop the current from passing through the computer the more likely you will reduce damage from short circuits. 3. Wipe your computer dry with a paper towel. 4. Before turning on your computer, make sure that all the liquid has dried. Note: If you want to replace your keyboard, contact the Customer Support Center. Refer to "Calling Lenovo" on page 135.

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. The more

quickly you stop the current from passing through the computer the more likely you will reduce damage

from short circuits.

3. Wipe your computer dry with a paper towel.

4. Before turning on your computer, make sure that all the liquid has dried.

Note:

If you want to replace your keyboard, contact the Customer Support Center. Refer to “Calling

Lenovo” on page 135.
