What do i Do I checked cpu nothing wrong I keep it in good shape.
1. Make sure the monitor is plugged into the integrated graphic adapter port. Make sure monitor is plugged in. Make sure monitor is set for correct input (VGA, DVI, HDMI, etc).
2. Reset the BIOS to default values in case you forced the BIOS to only send video to the PCI card. There is a procedure for that in the lenovo manual you can download for your PC.
