and install. After you select the updates you want, System Update automatically downloads and installs the
updates without any further intervention from you.
System Update is preinstalled on most Lenovo computers and is ready to run. The only prerequisite is
an active Internet connection. You can start the program manually, or you can use the schedule feature
to enable the program to search for updates automatically at specified intervals. You also can predefine
scheduled updates to search by severity (critical updates, critical and recommended updates, or all updates)
so the list you choose from contains only those update types that are of interest to you.
To open System Update , see "Accessing Lenovo programs on the Windows 7 operating system" on page 5
or "Accessing Lenovo programs on the Windows 8.1 operating system" on page 6.
If System Update is not currently installed on your computer, you can download it from the Lenovo Support
Web site at http://www.lenovo.com/support.

Cleaning and maintenance

With appropriate care and maintenance your computer will serve you reliably. The following topics offer
information to help you keep your computer in top working order.

Basics

Here are some basic points about keeping your computer functioning properly:
• Keep your computer in a clean, dry environment. Ensure that it rests on a flat, steady surface.
• Do not place items on top of the monitor or cover any of the vents in the monitor or computer. These
vents provide airflow to keep your computer from overheating.
• Keep food and drinks away from all parts of your computer. Food particles and spills might make the
keyboard and mouse stick and unusable.
• Do not get the power switches or other controls wet. Moisture can damage these parts and cause an
electrical hazard.
• Always disconnect a power cord by grasping the plug, but not the cord.

Cleaning your computer

It is a good practice to clean your computer periodically to protect the surfaces and ensure trouble-free
operation.
CAUTION:
Be sure to turn off the computer and monitor before cleaning the computer and monitor screen.
Computer
Use only mild cleaning solutions and a damp cloth to clean the painted surfaces of the computer.
Keyboard
To clean your computer keyboard, do the following:
1. Apply some isopropyl rubbing alcohol to a soft, dust-free cloth.
2. Wipe each keytop surface with the cloth. Wipe the keys one by one; if you wipe several keys at a time,
the cloth may hook onto an adjacent key and possibly damage it. Ensure that no liquid drips onto
or between the keys.
3. To remove any crumbs or dust from beneath the keys, you can use a camera blower with a brush
or cool air from a hair dryer.
