Troubleshooting
If your computer has an error, it typically displays a message or an error code, or makes a beep when you
turn it on. When you experience a problem, see the corresponding symptom and solution in this topic
to try to solve the problem by yourself.
Computer stops responding
Print these instructions now and keep them with your computer for reference later.
Problem : My computer is unresponsive (I cannot use the ThinkPad pointing device or the keyboard).
Solution : Do the following:
1. Remove all power sources from the computer and reset the system by inserting a straightened paper
clip into the emergency-reset hole in the bottom of the computer.
2. Reattach the ac power adapter and restart the computer. If the computer does not start up, continue
with step 3.
3. While the computer is turned off, remove all power sources from the computer and remove all external
devices that are attached to the computer (keyboard, mouse, printer, scanner, and so on). Reattach the
ac power adapter and restart the computer. If the computer still does not start up, call the Customer
Support Center.
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. 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.
