14. If required, you can find your country's Customer Support Center at the following Web address:<br />
http://www.lenovo.com/support/site.wss/document.do?sitestyle=lenovo&lndocid=migr-4hwse3. When<br />
calling the Customer Support Center, please make sure you have your machine model type, serial<br />
number and the computer in front of you. Also, if the machine is producing error codes, it is helpful to<br />
have the error screen on or the message written down.<br />
Making sure device drivers are current<br />
Device drivers are programs that contain instructions for the operating system about how to operate or<br />
“drive” a certain piece of hardware. Each hardware component on your computer has its own specific driver.<br />
If you add a new component, the operating system needs to be instructed on how to operate that piece<br />
of hardware. After you install the driver, the operating system can recognize the hardware component<br />
and understand how to use it.<br />
Note: Because drivers are programs, like any other file on your computer, they are susceptible to corruption<br />
and might not perform properly if corruption occurs.<br />
It is not always necessary to download the latest drivers. However, you should download the latest driver<br />
for a component if you notice poor performance from that component or if you added a new component.<br />
This may eliminate the driver as the potential cause of the problem.<br />
Getting the latest drivers from the Web site<br />
You can download and install updated device drivers from the <strong>Lenovo</strong> Web site by doing the following:<br />
1. Connect to the Internet.<br />
2. Go to:<br />
http://www.lenovo.com/support/site.wss/document.do?sitestyle=lenovo&lndocid=tpad-matrix<br />
Enter the product number of the computer or click Detect my system on the screen.<br />
3. Click Downloads and drivers.<br />
4. Follow the directions on the screen and install the necessary software.<br />
Getting the latest drivers using System Update<br />
The System Update program helps you keep the software on your system up-to-date. Update packages are<br />
stored on <strong>Lenovo</strong> servers and can be downloaded from the <strong>Lenovo</strong> Support Web site. Update packages can<br />
contain applications, device drivers, UEFI BIOS flashes, or software updates. When the System Update<br />
program connects to the <strong>Lenovo</strong> Support Web site, the System Update program automatically recognizes<br />
the machine type and model of your computer, the installed operating system, and the language of the<br />
operating system to determine what updates are available for your computer. The System Update program<br />
then displays a list of update packages and categorizes each update as critical, recommended, and<br />
optional to help you understand the importance. You have complete control of which updates to download<br />
and install. After you select the update packages you want, the System Update program automatically<br />
downloads and installs the updates without any further intervention from you.<br />
The System Update program is preinstalled on your computer and is ready to run. The only prerequisite is<br />
an active Internet connection. You can start the program manually, or you can use the schedule feature<br />
to enable the program to search for updates automatically at specified intervals. You also can predefine<br />
scheduled updates to search by severity (critical updates, critical and recommended updates, or all updates)<br />
so the list you choose from contains only those update types that are of interest to you.<br />
For more information about how to use the System Update, refer to “System Update” on page 37.<br />
