Samsung SUR40 which recently got stuck at boot up (see the photo below). Once the Kernel lib loaded, for some reason was getting stuck at:
StrongROM version 03.30 Build:_P
Powering it off or on, did not help. Neither did trying to get into the BIOS to try and change some things.
I did get this back up and running, and in the end the solution was quite simple - I had to physically take out the power cable (just powering it down was not enough); wait a few seconds and then plug the power cord in, and boot it back up.
