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. Press and hold the power button until the computer turns off. If you cannot turn off the computer by
pressing the power button, remove the ac power adapter and the removable battery. After the computer
is turned off, reconnect the ac power adapter and reinstall the removable battery, and then restart the
computer by pressing the power button. If the computer does not turn on, continue with step 2.
2. While the computer is turned off, remove all power sources from the computer (removable battery and
the ac power adapter). Plug in the ac power adapter while keeping the removable battery out of the
computer. If the computer does not turn back on, continue with step 3.
Note: When the computer starts up and enters the Windows environment, use the proper shutdown
procedure to turn off the computer. When the computer is off, reattach the removable battery and
restart the computer. If the computer does not start with the removable battery reattached, remove the
removable battery and again start with step 2. If the computer starts with ac power but does not start
when the removable battery is attached, call the Customer Support Center for support.
3. While the computer is off, remove all sources of power (removable battery and the ac power adapter).
Remove all external devices that are attached to your computer (keyboard, mouse, printer, scanner, and
so on). Repeat step 2. If step 2 is unsuccessful, continue with step 4.
Note: The following steps involve removing static sensitive components from your computer. Make sure
that you are properly grounded and remove all sources of power attached to the computer. If you are
uncomfortable or unsure about removing components, call the Customer Support Center for assistance.
4. While the computer is off, remove all sources of power and external hardware. Remove any non-original
memory module added to your computer. After removing the extra memory module and reinstalling the
original memory module, repeat step 2. If the computer still does not turn on, consult the user manual
for other customer-replaceable components that are attached to your computer.
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

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.
