How do I unlock my Fujitsu Siemens Celsius h250?

I recently wanted to use my Fujitsu Siemens Celsius h250 again for a long time, but when I press the button, I only see these 2 locks, which always "look up". Can anyone tell me how to get the laptop up and running so I can use it properly?

Look for a key combination to boot the laptop

This is not a lock, but an error message. He has a hardware error.

Somehow, you can't find what you are looking for

Can you still fix that? Last night he went after a few attempts and it worked so far everything.

This is not an error message xD

This is a code that probably indicates a hardware problem

There's certainly a data sheet where you can find out what these "Morsezeichen" mean… Villeicht is only the Bios battery is empty or there's a loose connection. In the worst case, your ram or mainbaord is broken

Have now looked longer in the manual, etc., but unfortunately found nothing to this error message.

Then look more generally to the topic… Z.B https://de.ifixit.com/...et+to+BIOS

Here it should have been fixed by a BIOS update
