For the record: all my problems seem to be gone since I updated to the latest HP BIOS release and removed the "power-on password". This can be done by changing the password and entering two empty fields for the new pass. That's a bit simpler than what HP support suggested me to do to get rid of it (opening the laptop and removing the CMOS battery) (Running Feisty now)
