hi there!

 

power off unit and hit the One Key Recovery button.

 

Perform the One Key Antivirus Feature and select full scan.

 

Make sure unit is plugged in-

 

Since Unit is new, this would be a good time to create Recovery Discs- this is very, very important.

 

When discs have been created, your safe.

 

Run the One Key Recovery Option and post back if issue persists.

 

Cheers!

Hi,

 

that's usually a graphics card problem.

 

Have you checked  at Device Manager and

 

whether or not there is an upgrade available at the

 

Lenovo site for driver downloads.

 

Also the knowledge base may provide an answer.

 

Let us know how you go.
