If you reset the BIOS settings and take the PC to sleep, it wakes up correctly.
After turning off the Core C6 State on the standard BIOS settings, the PC does not leave the sleep mode, and the coolers are switching on, but there is no video sound signal and the button on the system unit keeps flashing (which corresponds to the sleep mode).
