1. Turn the laptop off (not sleep or hibernate but off).
2. Connect an external monitor to the laptop.
3. Turn on the external monitor.
4. Turn on the laptop.
NOTE: You may have to press an "external monitor" button. Could be the f4 button or a button with two monitors on it, for the external monitor to work.
If you can see fine on the external monitor, then your attached display, or the ribbon cable that connects it, are your problem.
If you can't see on the external monitor at all, or the problem occurs on the external monitor as well, then it is probably the graphics card/GPU that is the problem, which may require the motherboard be replaced.
For being stuck on Aptio try this...
1. In the Aptio Setup Utility, select the "boot" menu and then select "Launch CSM" and change it to "enable".
2. Next select the "Security" menu and then select "secure Boot Control" and change to "disable".
3. Now select "Save & Exit" and press "yes".
4. Once you have done this, hold down the "power" button until the laptop turns off completely.
5. Now you want to power it back on and continually press the "F9" button for about ten seconds or until you are taken to the "Windows Recovery Menu".
6. In here select "Advanced Start Up" and then, once the recovery menu appears, select "Advance Options".
7. Choose "System Restore" and select a date prior to when the problem started.
The computer should now go through the restore process and then start normally for you.
