Does anyone have any idea what that means?

5.3 (flashing signal)

System board

The integrated controller timed out while waiting for the BIOS.

Disconnect all accessories from the notebook.

Shut down the notebook using a hard reset (press and hold the power button until the system switches off). Then restart.

Unfortunately does not work

As soon as I restart the laptop, the screen remains black and the caps lock key continues to flash

Ok, then maybe the other way around (the code), then the BIOS can't find a CPU. This is then a repair case.
