If required, you can find your country's Customer Support Center at the
following Web address: http://consumersupport.lenovo.com.
When calling the Customer Support Center, please make sure you have
your machine type, model, and serial number available and the
computer is in front of you. Also, if the machine is producing error
codes, it is helpful to have the error screen on or the message written
down.
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 new component, the operating system needs to 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:
Due to the fact that drivers are programs, like any other file on your
computer, they are susceptible to corruption and might not perform
properly if corruption occurs.
