Hello Patrik,
Please try to perform a BIOS recovery on your system:
1. Copy the recovery file (*.bio) to a bootable USB thumb drive.
You can download the BIOS recovery file here.
2. Place the thumb drive in a USB port of the target system.
3. Shut down the system and unplug AC power.
4. Open the chassis and remove the BIOS Configuration Jumper. See the
Technical Product Specification for details including the location of this jumper. Page 38
5. Power the system on.
6. Wait 2-5 minutes for the update to complete.
7. System will either turn off when the recovery process is completed or it
will prompt you to turn off the system.
8. Remove the thumb drive from the USB port.
9. Replace the BIOS Configuration Jumper.
10. Restart system.
If the problem continues, please send us an screenshot on how are you enabling the onboard VGA on the BIOS
Best regards,
Sergio S.
