Installing device drivers
Device drivers are programs that contain instructions for the operating system about how to operate or
“drive” a certain piece of hardware. Each hardware component on your computer has its own specific driver.
If you add a component, the operating system must be instructed on how to operate that piece of hardware.
After you install the driver, the operating system can recognize the hardware component and understand
how to use it.
Note: Because drivers are programs, like any other file on your computer, they are susceptible to corruption
and might not perform properly if corruption occurs.
It is not always necessary to download the latest drivers. However, you should download the latest driver for
a component when you notice poor performance from that component or when you added a component.
This action might eliminate the driver as the potential cause of a problem.

following:
1. Go to
http://www.lenovo.com/support.

The system update function of Lenovo Companion helps you keep the software on your computer up-to-

Lenovo Companion then displays a list of update packages and categorizes each update as critical,
recommended, or optional to help you understand the importance. You have complete control of which
updates to download and install. After you select the update packages you want, Lenovo Companion
automatically downloads and installs the updates.
Lenovo Companion is preinstalled on your computer 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
