iv Hardware Replacement Guide  
 
Overview  
This guide is intended to be used by customers who are replacing Customer  
Replaceable Units (CRUs). In this document, CRUs will be referred to as parts.  
This guide does not include procedures for all parts. It is expected that cables,  
switches, and certain mechanical parts can be replaced by trained service personnel  
without the need for step-by-step procedures.  
This guide contains instructions for replacing the following parts:  
Note: Use only the parts provided by Lenovo.

v Keyboard  
v Mouse  
Safety information  
Do not open your computer or attempt any repair before reading the “Important  
safety information” in the Safety and Warranty Guide that was included with your  
computer. To obtain a copy of the Safety and Warranty Guide, go to the World Wide  
Additional information resources  
If you have Internet access, the most up-to-date information for your computer is  
available from the World Wide Web.  
You can find the following information:  
v CRU removal and installation instructions  
v CRU removal and installation videos  
v Publications  
v Troubleshooting information  
v Parts information  
v Downloads and drivers  
v Links to other useful sources of information  
v Support phone list  
Tools required  
To replace some parts in your computer, you might need a flat-blade or Phillips  
screwdriver. Additional tools might be needed for certain parts.  
Handling static-sensitive devices  
Static electricity, although harmless to you, can seriously damage computer  
components and parts.

v
 
When replacing a part, do not open the static-protective package containing the  
new part until the defective part has been removed from the computer and you are  
ready to install the new part.  
When you handle parts and other computer components, take these precautions to  
avoid static-electricity damage:  
v Limit your movement. Movement can cause static electricity to build up around  
you.  
v Always handle parts and other computer components carefully. Handle  
adapters, memory modules, system boards, and microprocessors by the edges.  
Never touch any exposed circuitry.  
v Prevent others from touching the parts and other computer components.  
v Before you replace a new part, touch the static-protective package containing the  
part to a metal expansion-slot cover or other unpainted metal surface on the  
computer for at least two seconds. This reduces static electricity in the package  
and your body.  
v When possible, remove the new part from the static-protective packaging and  
install it directly in the computer without setting the part down. When this is  
not possible, place the static-protective package that the part came in on a  
smooth, level surface and place the part on it.  
v Do not place the part on the computer cover or other metal surface.
