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. If you no longer have this copy of the Safety and Warranty Guide , you
can obtain one online from the Support Web site at http://www.lenovo.com/
support.
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 information
v Publications
v Troubleshooting information
v Parts information
v Downloads and drivers
v Links to other useful sources of information
v Support phone list
To replace some parts in your computer, you will 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.
When you are 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 yourmovement.Movementcancausestatic-electricitytobuilduparound
you.
v Always handlepartsandothercomputercomponentscarefully.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,removethenewpartfromthestatic-protectivepackaging,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 notplacethepartonthecomputer coverorothermetalsurface.
