Re: No video on E6420 screen prior to Windows 7 loading.

Hi jamichau,

I suggest you to run Diagnostics on the laptop by connecting the external monitor to the laptop to view the screen. This is to check if there is any problem with the video card. Follow the steps to run PSA diagnostics:

  1. Connect an external monitor to the laptop.
  2. Restart the computer by tapping F12 key. Check the display on the external monitor.
  3. In the boot menu screen select Diagnostics from the list and hit enter.
  4. If the diagnostics displays an error, please reply with the right error message.

Please post the results.

Thanks & Regards,
Nikhil D
