Jean-Pierre van Riel, the exact same thing happened to me. I was under the impression that my motherboard gave out and was planning to take it to the service centre.
However I did not update Ubuntu; I rarely boot into Ubuntu these days - have been using Elementary. And I also have Windows 10 Insider Preview. Installed a bunch of updates both in Win 10 IP and Elementary and I cannot remember which one was the last.

But the issue is the same - totally bricked laptop. Nothing boots, F2 and F12 don't work. Shorting CL1 and CL2 doesn't help. Took out CMOS battery and put it back after a while; no change. Swapped HDD and RAM; no help.
I went and bought new CMOS battery too just to see if that helps.

I do not think the BIOS is outdated - Fujitsu's support page lists my
BIOS as the latest.

Title:
  [Fujitsu LIFEBOOK LH532 (UMA)] Ubuntu EFI install locks out firmware
  access

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  :~$ apt-cache policy grub-efi-amd64
  grub-efi-amd64:
    Installed: 2.00-22
    Candidate: 2.00-22

  EFI installation of Ubuntu clears out the boot entries in firmware leaving user with no option but boot Ubuntu. Pressing (F2) to enter BIOS Setup has no effect as does pressing (F12) for Boot Order.
  The only way to get back firmware access is to flash the bios using manufacturer provided utilities. Unfortunately Fujitsu doesn't provide a BIOS flash utility for Linux/Ubuntu. It is to be noted that installed Windows in EFI mode on the same system does not clear out firmware access but just adds the 'Windows Boot Loader' entry at the top of the boot sequence.
